Ok so here is the problem. I really don't know when this started happening but it suddenly just did. Just a heads up, my laptop has not been through a heavy fall or anything like that. Sometimes the charging indicator light does not light up but the battery still shows as charging in windows. Its at 89% since the last 2 hours. As soon as i unplug the charger, the laptop just turns off and does not start without it. I can't even contact acer support since my laptop is not in warranty anymore ;/. I just did not notice it before because my laptop is usually plugged in on my desk. Please need help asap. Thx in advance

Referring to a Toshiba Tecra 9100, model no: PT910E-602SF-EN

The power button normally doesn?t turn it on at all, though occasionally it boots up normally, starts to load windows, then always cuts out after 5-15 seconds anyway.

It still charges up the batteries fine, but won?t turn on. I?ve checked the ram, hard-drive, and I re-set the bios to defaults - nothing stops it from cutting out if you can get it to turn on.

Any ideas what could be the problem? Any help appreciated, it?s the second time one I?ve had - the same problem last time!


A:Tecra 9100 turns on intermittently, and turns off after 10-15 seconds


Have you already tried cleaning the fan? Maybe a lot of dust is blocking the fan so the notebook can?t start and turns off itself due a higher temperature. It would be worth a try cleaning it.

But in my opinion you have everything done what you can do and it looks like a mainboard malfunction. If cleaning the fan doesn?t help I think the mainboard is defective or something else. If you are familiar with notebook disassembling you can try to repair it yourself with second hand parts. Otherwise it?s time for a new notebook I think?

I have a problem with my laptop (Tecra S5 series).
Every time when I start or restart my laptop, the display is moving too slow, it has yellow stripes and sometimes is blinking.
When I open the Device manager I can see the Display Adapter (NVIDIA Quadro NVS 130M) with yellow circuit with a extension mark. When I go inside it says: The device cannot start. Code 10.

Then I have to go in Safe Mode, uninstall the drivers for NVIDIA Quadro NVS 130M, install again and restart. I have noticed that when this Display Adapter is OK, then I don't have problems with my laptop screen.

I want to connect my laptop to a DVI screen and it only has a DisplayPort (and VGA but I do want to get the full resolution) port.
So I need an adapter.
Can I use a passive adapter or do I need to buy an active?

A:Tecra R850-117: Need info about Display Port to DVI adapter


As far as I know the DisplayPort on the left side complies to the V1.1a standard.
This means that the DispplayPort is compatible with DVI and HDMI standards so you can use an DisplayPort to DVI or HDMI adapter.

So you could use something like that:

Got a Tecra M1 refusing to power up since few days.

The M1 has 3 led to indicate: (a) the AC power is connected (b) the power is on (c) the battery is available / charging.
Each of these can be green or amber.

The symptoms are the following:
- with AC adapter and batteries plugged, (a) and (c) are green
- when powering the laptop, the leb (b) is turing green for a fraction of a second; then start blinking amber with more or less 1 second frequency. Got a intermediate beep on speaker with the same frequency.
- display is bank. Not even bios is displayed.

I tried already the following:
1) remove AC and battery, wait a while, plug both and restart. Same issue
2) remove battery, boot on AC. Same issue.
3) remove AC, boot on battery. Same issue.

Any idea ?
Does anyone know the meaning of having this "power-o" led blinking amber.

A:Tecra M1 does not power up

Hi buddy,

Good job because this was described [HERE|]

Unfortunatley that?s everything what you can do if your notebook doesn?t start. At the moment it looks like a serious hardware malfunction and the mainboard or CPU could be affected.

I would recommend contacting an authorized service provider in your country. The guys can make an exact diagnostic and tell you how much a repair would cost.

Good luck! :)

PC at home is running XP Service Pack 2 and the internet is supplied by a NetGear WG111v2 Wireless USB Adapter and has been fine for a number of years now.
I've just added an Access Point to the network to help with the signal around the house. This is all working fine with a laptop running Vista and looked to be working fine with the adapter but I was having massive problems with the NetGear Wizard wishing to always validate the settings and always scanning.

I uninstalled the driver and wizard and started again, no more validate settings and connection details saved fine. Connected but still scanning so I've now removed the wiazard and use the Windows utility to detect and control the wireless and this works but only for a few minutes.

The issue appears to be with the adapter, after between 2 and 6 mins the blue light goes off and I lose net connection. The only way to get it back is via a PC reboot and then it all works fine again for 2 - 6 mins.

Is this a known issue with the adapter? Few years old so could be it's faulty but with USB devices I would expect it to fail and not work rather than the symptoms I have.

A:Netgear USB Adapter Turns Off?

I wonder if it is the adapter, or power settings that turn off the port after an idle time. In your power options, in the advanced section, there is a section on USB where "USB-suspend" can be enabled or disabled.

My Tecra M2 will start-up, but the battery is always dead, if I remove battery and just use the power cord the machine starts up fine work as it should then just cuts out, after five minutes.

It also starts up with battery and power cord but after five minutes as before but flickers then dies.
If i leave the machine closed to recharge it only charges for five minutes before the green power cord led goes out with the amber battery light. Then the power cord light flashes amber.
I disconnect the power and remove battery to get it back to recharging status.

The machine was working fine before and is running on xp pro.

On this virtual way it is not easy to say what the problem is but after reading your posting I believe your Tecra has problem with power supply electronic.
To be honest I don?t think you can do anything about that.

Of course it can be checked by Toshiba service but I think it is too expensive for this old piece of hardware.

I'm pretty confused, and I'm hoping someone here can help me. Last week I took my laptop into Best Buy for a diagnostic due to some issues. After I picked it up, I noticed that every time I restart/turn on the computer, the wireless adapter turns on for a couple of seconds then shuts back off, and I have to manually press the adapter button twice for it to turn back on. I've never had this happen before.... and I reinstalled the OS last night at the recommendation of Best Buy because of the other issues, yet this adapter thing is still happening. The wireless works perfectly fine after I turn it on, but normally my adapter turns on automatically.

Does anyone know why this might be happening and what I can do to fix it? Right now it's just more of an annoyance that I have to turn the adapter on every time, but I'm worried that means something is wrong? Like I said, this didn't start happening until a week ago.

The laptop is an HP G60, running windows 7 home premium. The adapter is an Atheros AR5007.

A:Wireless adapter turns off each reboot?

You could check the power settings in the properties for the adapter. Your system might be turning it off to conserve power. Also you might check your power settings in control panel to see if it is set to the minimum power settings which could turn off the adapter.
Some laptops I have seen with bios settings having to do with adapters on and off.

I've a Tecra M11 (Windows7 64-bit). The Toshiba Power Saver Settings V8.9.3.64 are installed.

My problem is: The fan is almost always on with maximum speed, whereby there is no processor load (only 1-5%). That is really loud and annoying!

What I've done so far: I switched the cooling method to "battery optimized" for both power modi, but without any effect.

1) Is there any quite office mode available (as many other notebook manufacturers offer for there business notebooks) to work in a silent environment?
2) Is there any option to deinstall the Toshiba Power Saver Settings and use the standard Windows7 cooling methods, because Windows 7 in general offers a passive cooling option with the effect that the fan is off.

Thanks a lot!

A:Tecra M11 power saver settings - fan almost always on

I?m really wondering this ?cooling method? settings didn?t help. I have Tecra A11 with Win7 64 bit and my notebook is absolutely silent. Changing these settings on several other Toshiba notebooks the result was the same. Notebook was much quieter.

Which power plan do you use?
Have you noticed some difference when you switch to ?Toshiba eco mode??

# As far as I know such mode is not available on Toshiba notebooks.
# You can remove Toshiba power saver but it is a little bit complicated. You must remove whole Toshiba value added package. Later you must install VAP again but not in standard but custom mode and remove check mark in front of applications you don?t want to install.

I never heard about such feature and from my knowledge such option does not exists in the BIOS released for Toshiba notebooks.

In my case the BIOS contains an option like Wake Up on LAN or Wake up on Keyboard.
This allows the notebook to wake up from sleep mode by LAN or keyboard.

The option which you are looking for should be something like ?Power on USB? etc? but I doubt its part of the current BIOS

My Dell D800 laptop stop working.

When I plug the ac-adapter the power light goes off on the adapter. It is obvious short on the motherboard. I did took it apart and look for some problem around DC-jack, but I don't think the problem is there. All the accessories are off . It is only mobo now by it self and does same thing. Anybody knows where I should look for the short. Which chip or diode it could be? I heard it is very common problem with D800 and D600 models. Since I am pretty good with soldering I think, and it is my hobby as well I would like to repair the mobo my self instead replace. Definitely would be much cheaper as well.

Thanks in advance for any input on this matter.

A:Dell D800 AC adapter turns off when plug in

Some laptops have a separate internal DC converter, and some DC converters are part of the motherboard. If you haven't tried another AC adapter, I would do that first. After replacing the AC adapter, check the DC jack for a high resistance using a good multimeter... A normal resistance would be around a half Meg ohm. If the internals are shorted, the resistance would be much lower. Unless you have the skill and tools to do surface mount soldering, I wouldn't attempt a repair

- computer got extremely hot on the surface (I had tried to open the computer and to clean inside, but it still got extremely hot)

- if the computer does not start, is is because of the internal HDD problem (discovered once in a while it recognized an old HDD, I had attached to the internal port, as otherwise the DVD-drive did not work) - and easy repair is possible

Possibly one of the processes hangs somewhere in the background and jams the CPU which cause higher heat dissipation. This could lead to higher temperature and the overheating protection shuts down the notebook to prevent the hardware from overheating.

Not sure why this happens but maybe you should reinstall the Eco Utility which you can find on the Toshiba European driver page.

Dear all,

I have 3 Tecra A9 Notebooks that came with a T7100 Core2Duo CPU running at 1.8Ghz with 2MB Cache. Upgraded all 3 to a T7700 running at 2.4Ghz having 4MB Cache. According To Intel the TDP of both CPUs is at 35W. Notebooks don?t get hot, not even warm actually. The CPU FAN switches itself to full power right after displaying the BIOS screen with the Toshiba Logo. Running Bios Version 2.1 on all 3 systems, having same behavior on all 3 systems. CPU properly recognized under WinXP, Win7 and Win10. Is there any way to get the CPU fan adjusted back to normal? The system isn?t any hotter than before the CPU Upgrade, just for some reason the BIOS now decided the fan has to run with full power. I even exchanged one of the CPU Fans with the one from a Tecra A10 Notebook but had the same effect than with the original fan. Having no Idea what I could do. Hope for your help!

as soon as I'm trying to boot the laptop it gives 1 little click (Supposedly the HDD trying to start) and then it stops booting in an instant. It doesn't have more then 0.1 seconds to turn off again and the only sign of life is that little click. From that moment on the battery led will turn completely off (while the charger is still inside) and the power led will start flashing orange in this order: Short, Long, Short, Short, Short, Short, Long Long (Repeat).

anyone has any clue what's happening here? I'm expecting a defect in the mainboard but it might be something else.
(Good to note is, that we own 2 of the same laptops. Both the charger and battery work in the other laptop. I've also tried to boot it without the ram and HDD but no succes either.)

Kind regards,

After rebooting (this happened a couple of times...with the hdd and today with the ssd so it should not be their fault) the windows or toshiba screen do not appears only a black screen, no disc activity and the fan works like crazy!!! I stop this after 1-2 minutes because nothing happen!

We are having a problem with the battery on one of our laptops. When left for an hour or so the laptop shuts down as the battery runs out of power. We have fitted a new battery but still only get about 1.5 hours.
In addition the fan is running constantly. I have looked at the PC Healthcheck software which shows as follows:
*Electric Power*
Remaining charge 14%
System power consumption 40%
Battery Health good
*Temperature and Fan*
CPU temperature 67%
Internal system temperature 56%
Fan speed 88%

I would appreciate any suggestions.

A:Tecra M11-130 battery not holding power and fan running constantly


Do you have any apps or services hogging the CPU?

Maybe there is something in Task Manager using 90%+ CPU. If not, maybe there is dust buildup in the heatsink or some other cooling problem.

If you turn on eco mode, does that extend the battery to 2+ hours?

I have an Tecra R950-16L for about 3 months now everything works fine. Now since a few days I have the problem, that sometimes, especially after I transported the notebook before, the internal display stays black after I power on the notebook.

I can blindly type my password and see from the disc activity that windows is starting probably, but no display is shown.

After I move the notebook around and shake it a bit it sometimes works again and the it stays working until I move the notebook again somewhere else (at least this is what seems to make the effect occur).

Seems to me like a loose connector to the display or something like that?

Is there any chance to repair this on my own?
I do need my notebook all the time and do not want to send it for repair if not 100% neccessary.

What do you suggest?

>Seems to me like a loose connector to the display or something like that?

Yes, it looks like there is a loose connection or maybe something wrong with the lid sensor.

>Is there any chance to repair this on my own?
I don?t think so.
You would need to check what?s wrong exactly. After this has been checked, you would need to disassemble the notebook and this is not easy. Last but not least you would need the compatible parts to replace the affected hardware? I don?t think you can do that?

>I do need my notebook all the time and do not want to send it for repair if not 100% necessary.
Well, you could ask the Toshiba authorized service provider for details and how long such repair would take.

Is there a BIOS update that allows me to select "BOTH" as an option for the Power On Display?
Currently it only lists Auto-Select and Internal.

Auto-Select only outputs to the external screen if one is connected.
I need to set the default as output on both screens.

Older Toshibas do this. In fact, every other Toshiba I've used has this feature.
As a presentation/hire/conference laptop, this is an important feature.

And yes, I've updated the BIOS to the latest version.

i did the offered upgrade to W8, i am very satisfied with the W8 system, but the problem is that the notebook is consuming battery also in the hibernate mode.

I would understand that the power consumption will be in the sleep mode, but on the hibernate mode?

I found out that when the computer enters the sleep mode or hibernate mode and i open the lid, the computer automatically starts EVEN if the option to "power up computer when lid open" is unchecked.

When i select to power off computer - it does not react to open lid, i have to press the power button.

The problem could be in the windows system, that the OS tolds the computer to wake up when the lid closed.

The problem is, that the computer starts charging everytime i wake up from hibernation (i had my office 15minutes from home, and it consumes about 1-2% from battery.

It is quite anoying that my full charge battery capacity is on 83% of original one (i bought my PC in June2012).

I had Lenovo T60 7yrs ago, and there was an option to start charging the battery only when the battery charge was under 95% and it saves the battery capacity.

Does anybody have some clue?

Thank you!

Fact is that battery capacity will be reduced even if the notebook is completely OFF. Battery capacity will lose few percent of capacity. To reduce this check -

Looking for some help, think on right track but want to confirm and get things fixed.

Have a Tecra R840-S8450 that is having issues powering up. When you try to start it, the plug orange light flashes a code. That code is 01001010 which I derived from shortlong short short long short long short blinks of the orange power light.

So this is great progress, assuming I translated that right to 52h, which equals "EVER5V voltage is under or equal to 4.5V when the computer is
booting up". However it does not tell me what is wrong in such a way that I can try to do something to fix it.

Hi there,

I have a Tecra m9 laptop and when I try to power it on, it flashes with an orange light in this sequence:

6 short blinks, 1 long blink, 1 short blink, a gap, and then it repeats.

Does anyone know what the problem is?
Any advice would be greatly appreciated.


A:Tecra M9 - no power up, orange light error code sequence

What you see is blinking code. The blinking LED provides an error code. Short means 0 and long means 1.

Hexadecimal code can be ?read? by service partner. When the microcontroller detects some problem with power supply the blinking code will be sent. Unfortunately you cannot do anything alone. Contact nearest service partner in your country and ask for help.

All you can try at the moment is to remove battery and start notebook with AC power supply only.

I need to "check cables and power", as a result of the Seatools for Dos test and on start up "Media failure, check cables PXE-E61" message. I also get a message from the CHKDSK using the XP Pro CD, saying after 26% that "The volumn appears to contain one or more unrecoverable problems".

Do I remove all B6 screws or what else - to remove the rear cover to "check the cables"?

The start up defaults to the Safe Mode screen, then to BSOD no matter which choice is taken, the BSOD is too short a time to read the message and their is no option in Safe Mode choices to turn off "Restart on failure".

I have removed and reinserted the HDD and RAM with no change to issue.

Hope this makes sense and someone can give advice.



A:How to remove back cover of Tecra S1 PT831A to check cable and power?


Every notebook has in BIOS the list of all bootable devices. If none of them can be used the last one, LAN port, will be checked and then you will see this PXE-E61 message.
So the problem can be your HDD.

Start with HDD check. Enter BIOS and set it to default settings. Restart notebook and check if HDD is recognized and listed properly in BIOS settings. If yes there is no problem with connectors.

I recommend you to obtain new HDD for testing purposes. Put new HDD and try to install OS using original Toshiba recovery disc.

My computer regularly turns off all by itself. It could be anywhere from 3 miniutes to 3-4 hours for it to turn off by itself. When I unplug the computer power cord and plug it in again then the power turns on again but usually turns off again after awhile. Why does my computer turn off by itself and how can I resolve this problem?

A:Power on computer turns off by itself

A few initial thoughts.

- How old is the PC? If it isn't that new have you ever cleaned it out inside?

It could be a heat related issue although I would of thought you would get a warning before shutdown (although not always). If the temperature reaches or exceeds the temperature set in the BIOS the system will shutdown to protect itself.

- If it runs for a while, then shuts off. When you turn it back on does it normally shutdown again after a very short time? Or can it run for ages again before turning off?

My computer has been running amazingly untill about a week ago it started shutting off right in the middle of operation. When I would boot it back up Microsoft would do the "Send error report" thing and it would send me to a web page saying that it was a hardware problem but it didn't know what hardwear was failing. It gave me a list of possible:
If overclocking turn off (Which I was and did disable)
Check Prossesor (My AMD 64 X2 +4200 is brand new and appears to be working fine)
Over packed power strip (Not a problem)
And Power supply. ( I think this is the most likly but have no way of proving it. I'm running 4 Hard drives. 1 Floppy. 2 CD drives. PCIe graphics card. 2 180mm fans and 1 80mm. all on a 450w power supply. Is that too much for it to handle? and Yes it's all nessisary.)

A:Computer turns off as if power went out.

It also can depend on the quality of the power supply. A cheap PSU will say 450 W but this is a peak value, and is an unrealistic dream. If it is a name brand or one of high quality it will put out a constant 450w. Check the label on the PSU to see if it is 450 Peak power, or 450 Constant. If it is peak, I would be looking into getting a more powerful PSU. I personally like to buy quality PSUs. I have a Cooler Master True 550w and it has never given me a problem.

Wondering if someone could shine a little light my way. My boyfriend has an emachine desktop W4682 and just tonight it has started giving me two problems.
First when turning on the pc the power light turns on and stays on, you can hear the fan humming but nothing else happens... no signal to the monitor. Something that I noticed was that the light for the dvd+-rw drive stayed on too. Thinking that maybe the dvd drive might be the problem, I opened the tower and disconnected the dvd drive. So far so good. The pc turned on and booted completely. After a couple of minutes of using the pc I started getting an error that said "power surge on hub port" and all I could do (after reading a few posts here and there) is turn off the usb alert on the advanced options.
For now I am able to use the pc but I'm worried that I might be causing it some permanent damage by leaving it as is. Best idea yet is to buy a better power supply? Anybody got a better one?

*Not expecting miracles here. I know of the little potential the emachines have*

A:Power light turns on but nothing else happens

G'day Myzteryh, these kinds of problems present difficult answers, quite obviously there is a malfunction of some type but what is the best course of action.
It is possible that some kind of malfunction has happened within the DVD combo or some other problem has affected the DVD combo but not knowing becomes difficult. The usb indication also is a consideration.
You could take it to a shop but they probably would not do more than what I am about to suggest.
It would probably be pertinent to obtain "Everest Home" off the net, (google it, Lavalys) this is an analysis program that can be helpful, remove any unneccessary USB stuff, load the Everest program, if you are able to, open it, then open the computer icon in it, then open the sensors section. This will show voltages and temperatures within the machine. If you could somehow copy and paste that page here would be nice, reallly what we are most interested in is the voltage readings, you can expect the table to show suggested readings on the left and actual readings on the right. I do feel you may find some way to achieve this without much problem and we may be able to work out what may be happening.
Do not leave the machine running for any period longer than neccessary at this time. (give it some thought)
If any of the twelve volt readings are above 14 Volts just switch it off and replace the power unit without any further testing.
There may be other ideas on how to address this problem.

Cheers, qldit.

A:Power on computer turns off by itself very often

This could be caused by a component of your computer heating up and telling the computer to shut down to prevent over heating. Make sure the computer is clean on the inside first and foremost! I suggest finding a temperature monitoring program like MBM5 or speed fan so you can tell just how hot things are getting. Hope that helps! Give it a shot and tell us the results.

This is a common problem (I see lots of posts)
The problem source is the [Dell] AC adapter.  PA-21 Family, 65W, P/N: NX061.  It is made in China.
I have an XPS M1330.  Using Dell after warranty service, replaced the Mother Board twice, replaced the battery twice, replaced the AC adapter twice - not fixing it.
Turns out the power warning message is very informative.  It states "Please connect a Dell 65W AC adapter or greater for best system performance".  So, I plugged in my Dell 95W adapter - WOW Problem Solved.
A lab test of my new Dell 65W AC adapter shows it to be 64.6 watts.  If this unit gets hot (like after several hours of use), it may not put out the full 65 watts - the system may not recognize the adapter, it may power the system ok, but won't charge the battery.
These units burn out after only a few months of use. Their cables are too fragile. If Dell's or their supplier's Quality Control can't produce a reliable 65W product - I found seveal "Made In USA" universal adapters.

A:AC Adapter - Alert - "AC power adapter wattage and type cannot be determined"

I'm new here and have a problem with my laptop. It's a fairly old vaio about 2-3 years. It recently started to turn off randomly, no warnings, not even a BSOD. I have searched and non of the other computer shutting down problems have the same symptoms.

Let me explain. When plugged into the wall via the AC power adapter, when idling or waiting for games to load etc. it may choose to shut down unexpectedly. Now I've been having this problem for a couple of weeks now and when it's running on the battery, it's fine, it can run till the battery is empty without shutting down, this is bout 1 hour and 30 mins. If it was connected to the power adapter, it would certainly shut down much earlier than this.

Heres the weird bit. When connected to the wall via the AC power adapter, it will NOT shut down if a 3D application is running, this includes playing games. When there is nothing 3D to render, such as when games are loading or it is idling on the desktop, it will certainly shut down, randomly. Another thing is that it will also NOT shut down if running in safe mode. I have left it on safe mode for about 5 hours for a test and no shut downs. Only when in normal mode it will. I have also left a game running for around that long in normal mode and no shut downs. Now to prevent my computer from random shut downs when I am using it, I continuously run a 3D modeling program in the background.

Hi! Yesterday, I turned my PC on from 1:00PM to 12:00AM. After that, I turned it on at 7:30AM, and after 4-5 hours of working, it turned itself off (directly, but the green LED on the case was still lighting until I kept my finger pressing on the Power button. Then the light was gone). After that, I opened it again, but after about 3 hours of continuous working, it stopped in the same way as before - with the green LED lighting. I left it for a couple of hours. Then turned it on again, but this time, after an hour of working, it stopped!
For knowledge, I faced this problem months ago, when I used to turn it on for 10 hours daily (for about a month)!

A:My PC Turns Itself off With the Green Power LED Lighting!!!!

An intermittent power issue? I would be inclined to suspect the power supply or motherboard being at fault, but it really could be a multitude of different things. First of all I would check to make sure all of the cables are properly secured. Also make sure your computer and display are plugged into a surge protector, this is important. If you know what your looking for open up the case and make sure that the ATX power plugs are secured properly and that there isn't too much dust in there, especially inside the heatsinks.

Hi,     As you mentioned latop turns on but nothing else happens, please turn off your laptop and turn the laptop on and keep tapping f11 key on keyboard now you must see recovery manager screen,select system restore on the list and select earlier date when your laptop was working fine and click finish at bottom once the laptop restarts you should be able to use without any problem, If not then check lights on caps and num lock whether it is blinking if yes then check how many times caps lock blink and reply back to this message, and if their no light blinking then you might have to reseat RAM and HDD even after reseat if still their is no display try connecting it to external monitor and check if their is no display then it should be problem with motherboard.  Thanks.ChetanI work on behalf of HPPlease click ?Accept as Solution ? on the post that solves your issue to help others find the solution.Click the KUDOS STAR on the left to say ?Thanks? for helping!

When I turn on my computer, a blank blue screen comes up and remains.  The startup sequence does not initiate and the computer will turn off after a minute or so.  Hitting the esc key after power-on gets me to the "Choose an Option" page.  From "Advanced Options", I have tried "System Restore" and "Startup Repair" neither fixed the problem.  Unable to boot in safe mode or change any of the startup settings because the system startup (restart) sequence is broken. A hard system reset did not work and pushing the F2 Key does not bring up the sys diag page. At this point, it seems that the only options left are trying to boot from a USB device or doing a PC Reset (keep my files)? Any suggestions would be appreciated. Thanks

I have an Averatec 3200 series laptop that has XP home edition,512MB DDR, 80GB HDD,AMD Athlon 2200+, when I turn the power on the blue power light comes on and i can hear the fan run but there is a series of three beeps and then silence and then keeps repeating the sequence of beeps until i just turn it off but the screen never lights up or comes on.
The last time that the laptop was on and working, while i was in the middle of an application, the screen had lines running across the screen (up & down) and the whole thing froze up and when i turned it off and then back on this is the problem i was having. Is there anything i can do to salvage this laptop or is gone? Thanks to anyone who can help me!!!

A:laptop power turns on but screen doesnt

Sounds like the laptop is not able to do the POST successfully. Try removing everything non-essential from the laptop (hard drive, optical drive, graphics card if it is not soldered onto the motherboard, etc.) and try powering it on. If that succeeds, add the additional components to the computer one by one until you isolate the one causing the POST to fail.

Good day, So I can keep trying to turn it on and it does the same thing everytime. Lights turn on, battery light turns on orange, not once but twice. AC comes on green and then orange.. However it may be orange because of the battery light illuminating it and it could be un lite. Fans or hardrive seem to fire up in this short time. The battery is connected and AC is plugged in as the battery doesnt last long so I mostly only use it with AC. The screen doesnt flinch in this time. Had no problems previously. Any help would be greatly appreciated.Thanks,Jesse

Hi Jesse, Welcome to the community. Sounds like a motherboard failure. Unfortunately you will need a new motherboard. Vince.

Computer info:
The computer is an HP Pavilion ze2000 laptop.

How do I stop my computer from turning off randomly, or stop it from not turning on at all?
Or, what hardware could be causing the problem?

(1)When I press the power button, the display will turn all gray and then it powers off a second after pressing the button.

(2)A couple days ago, I was able to turn it on, and when I could, it would randomly power off while I'm using it, without warning.

Figured this out so far...
So far, I can guess it's a problem with a loose hardware
because if I hold it a certain way, it won't turn on(1), until maybe if I hold it a different way (upside down, tilted to the side, etc). Or, if it's already on, and I leave it sitting for a while, it stays on... until I pick it up(2).

Thanks for reading this, and many thanks if you have a solution!

I reformatted my PC a few days ago and since then the monitor keeps shutting down randomly. The screen goes black and message 'no signal detected' appears then screen turns off, although power remains on (monitor power light turns to amber). The pc itself remains on and running - it doesn't shut down. I then have to shut down and turn pc back on manually.

Last night when watching a video file, screen blacked out and shut down. The audio of the video file also crashed so I assume it caused a problem to the pc? I'm not sure. If it didn't, surely the audio would continue.

The monitor is running of the onboard graphics card (motherboard) and bios setting is set as 'onboard VGA enabled' - my graphics card doesn't work and haven't had time to replace yet. My monitor has been running off the onboard VGA for a while now without any problems until I did the reformat.

I have checked cables and heating and can't find the problem. Please help!

Model: HP Pavillion 15 ak007txOriginal OS: FREE DOSCurrent OS: Windows 10 64 bit Problem: I tried to update the BIOS using this file:Released:2016-07-05File name: sp76335.exeVersion F.80It gave me a Blue Screen of Death and the computer restarted. After restarting I only get a blank screen, the fan also does not turn on, there's no text and no way to access the BIOS nor the boot menu.The Caps Lock led does not blink but the power button blinks every 2 seconds indefinitely,every time the light goes off a click sound is heard from my laptop. This, according to HP, suggests a BIOS Corruption Failure. What I've tried:I have removed the battery and tried to perform the hard reset procedure but that does not help.The only progres that i have had is that i tried the windows logo+b button and now the blinking stops and the power button stays on that too indefinitely.i have tried this method many times but to no avail. I also tried creating a usb bios recovery as mentioned by HP and tried the windows logo + B button combination but still nothing has happened.I hold the windows logo + B, then turn on the computer. Nothing happens. I have tried holding them for different lengths of time, there's no beeps, no text on the screen, nothing.  Please help me out,What am I missing?

Basically what the title says. I have my power options for my monitor timeout set to never turn off. It's a desktop, and I think I can trace the problem to a certain program. I have Arcsoft Totalmedia Theatre installed for playing BluRay movies and when I run it, it changes the display options back to Windows Vista Basic. It would seem that the power option changes itself back after I close this program and Vista goes back to Aero mode.

Any ideas what I could do to fix this? I use the program a lot and I absolutely hate turning my monitors back on.

A:Vista turns off monitor even though power options are set to never

I would remove Arcsoft Total media Theatre, then reset Vista, defragment, and reboot, then reinstall ArcSoft TotalMedia Theatre, and see if it will behave next time.

i have a computer that when you plug the power cord into the powersupply it turns on.
I removed all the connectors for the PS, HD, and any others that connect to the front panel, and the computer still comes on once you plug in the power cord.
Bad Mobo? or Bad PS?

It could just be a BIOS setting on the motherboard. See if there is some type of power-up option in one of the BIOS configuration screens.

To be clear, my PC turns on and seems to run exactly as it should, so this is possibly more of a cosmetic/superficial issue. The little light located on the power button no longer lights up when the PC is powered on. Strangely, the light still blinks on and off as it should when the PC is in sleep mode, so the light still has some functionality.My PC is only a couple of months old, so I'm just a little concerned that this could be a sign of things to come. I hope that other components don't start failing on me.Does anyone here have any possible explanations?Thanks.

My roommate tried to "fix" his PC but god knows he doesn't know crap. The PC acts like it is going to turn on, but the light on the front of the tower does not light up, nor does the display. The light on the motherboard is solid green, and he is still able to charge a phone through the PC, so I'm guessing the power supply is good if it can do all of this. At this point I am at a loss because I'm normally very good with this stuff, any suggestions? and I don't believe it's the video card.

Hi broken_biker69,

I'm just wondering if this is something quite basic. Please try the following:

Remove the Power Adaptor
Remove the Battery
Remove any other external devices (ie USB devices)
Hold down the ON button for 30 seconds
Then put the Power Adaptor in ONLY
Turn on the Power at the wall (just in case!)
Turn on the computer

If that works please reply (to this thread)

When i try and connect the 4 prong power source to the motherboard, the fans and lights quickly flash and stop spinning after about 1/4 of a turn.
When i disconnect the 4prong power cable, and only leave the larger power cable in, the pc turns on like normal and stays on, but displays no picture on the monitor and also the mouse doesnt light up?
Am i right in thinking that the processor has broken? and that the pc needs the 4prong power source to function properly?
please help,

I have a Dell Inspiron 530 (desktop) with Vista Home Premium. Until the other day, when I pushed the power button to start the PC, it turned blue and the PC went through the boot-up process. Now, it turns yellow and nothing happens unless I do more. So I push and hold the power button until it turns off. Then, I push the button a bit more strongly and it turns blue and boots.

My first thought was that the power switch for this 2008 PC is getting old and that I may become unable to boot at all. So I have decided to just let it go into sleep mode for now rather than turning it off for the day.

Any ideas on solving the yellow light issue?


A:Power button turns yellow instead of blue

It's an error indicator (not a failing switch).

Depending on the model, there may be other error indicators as well. In any case, q quick search found this: Inspiron 530 steady amber power light. - General Hardware - Desktop - Dell Community

Hi, My battery seems to hold a charge very well. However, the problem is when I try to move my laptop on battery power; it suddnely turns off. It also shuts down when jostled or bumped. The battery is great when the laptop is stationary. I noticed this problem when I move from one class to another: The Aspire V works great during class, but the moment I shut it and put it in my backpack it shurts down and I need to reboot it for the next class. The laptop is great when it is plugged in. This seems like a hardware issue but I don't know what to do. Thanks for your help!

It might be the power supply, a lot of the Gateway and eMachine computers have problematic power supplies. See if you can borrow a power supply, say from anther computer, and try it.

I had no problems whatsoever when I had Windows 7. However, after upgrading to Windows 10, I've gotten several BSOD crashes. I think I have a general idea of what's happening, but not why.
As well as I can figure, my computer seems to be crashing after going idle for a few minutes. I looked up "windows 10 bsod after going idle" on Google and found lots of threads that seem to describe the same issue, but I'll explain anyway in case there are any hints I'm not noticing.
I originally had the power saving settings set to turn the monitor off after 5 minutes and put the computer to sleep after 20. After the monitor turns off, the HD light shows the HD is being accessed heavily (because of automatic maintenance tasks?). But after a few minutes the light stops flickering and just stays on constantly. If I jiggle the mouse to turn the monitor back on, the screen is either blank or frozen, the mouse cursor is the spinning wheel for a while (I can move it around but that's all), I can't start Task Manager or anything, and then I get a BSOD.

Hello, I'm new to these forums. I think I'm in the right area, if not I'm really sorry.

My problem is my pc won't turn on. One early morning it was already running, just fine running the scheduled virus scanner. Around noon when I came back to check on it, there was no video and I had to force it to power down/reset by holding down the power switch. After that, it wouldn't show any sign of life.. none at all, no noise, no crackle, no smoke or fire, or smell.. until just recently.

I did a number of tests already. This is what (I think) I've found out.

It does not seem the PSU is the culprit.

I brought the PSU to a shop and asked them to check it for me.. they said it was fine.
It worked in my friend's computer, which is identical stock-wise (mine only has a different PSU and one more RAM card)
Taking the stock PSU from my friend's PC and inserting it in mine did not boot up my PC

The red and black wires on the power switch is okay on continuity. This is proven with the next thing.

The computer came to life! Or I thought it did. Unplugging ONLY the P4 molex connector allows the PSU to turn on, where it was not before. There is no video however, and it doesn't seem like anything else turns on. Testing that connector, I get 12V which seems right.

This connector, when disconnected, keeps my PSU from powering on.
I've reset the BIOS on my mobo and the canisters on it look alright. After this, I'm not sure what else ... Read more
