Aspire s7-191-6447 LEDs both dark, charger voltage...

Q: Aspire s7-191-6447 LEDs both dark, charger voltage...

Hi, Used my Aspire s7-191-6447 (Windows 8.1) as recently as last night without problems. This morning, LEDs are dark, even when the charger is plugged in, and it doesn't start. My voltmeter shows the charger output as +42 V, which seems way high even without a load (nominal is +19 V / 3.42 A). This laptop has an external battery pack that is marked as nominal input +19V / 3.42 A and output +11.1 V / 484 mA. (So it appears the actual operating voltage going into the laptop itself is +11.1 V. I'm confused about why the voltage would be further stepped down, but whatever.) I removed the external battery pack from the laptop, hooked it up with the charger, and looked at its output (i.e., the second plug that goes into the laptop). Same +42 V. Has anyone seen such a high unloaded voltage coming out of their LiteOn charger? Is it likely to have fried the laptop? Thanks in advance,Doug

It came with HP original charger 18.5V | 3.5A 65W but when I looked under the battery on my laptop it says 19.5V | 2.31A  I google about replacement charger fo Folio 9470m and there is allot of it with 18.5V | 3.5A 65W.  My question is, how can I be sure tahat this is the right charger? If it is not, can this diference in Voltage damage my laptop?

I have Aspire S7-392 for almost three years. I charged the laptop for few hours and then switched off the power. After few hours tried to turn it on and the laptop won't start. I put the AC adapter to charge again but see that LEDs do not turn on with AC adapter. Checked the adapter and it seems to be giving correct power output. After searching other threads tried the following:battery reset for 4 secTightening all of the screws on the backbattery reset with power button for 10 sec None of these seem to work. Any suggestions? Will replacing battery help in this situation?

My Dell Inspiron 17R 5720 doesn't recognize charger any more. And unfortunately my warranty expired 2 month ago.It was plugged in and working in the morning, but then in the afternoon I noticed that it was running on the battery only. It wont start without battery (just charger plugged in).
1. So here what I have done to debug. Me and my brother, we have purchased the same Dell laptops at the same time a year and a bit ago. This is why for a debugging purposes it was good.I took my charger and plugged in to his computer. And it works. Definitely not the charger issue I guess. And when I plug charger in to my computer, green light is still on the charger. And I have the original charger that came with the laptop.
2. Now, laptop works on the battery only, so this means that motherboard is working. I guess.
3. Next thing I did was unplugged charger and removed the battery from the laptop. Then I pushed and hold "Power" button for 45 seconds to discharge a flea charge. Plugged charger back in but laptop wont start.
4. Next I started laptop on the battery, went to BIOS and checked if the charger is recognized in the BIOS. No, it doesn't recognize charger. So, if it is not a charger then what else can it be?
5. Laptop doesn't have any strange smells so I'm not sure if anything happened with the motherboard, but I would assume mother board is ok because it works of the battery.

A:Dell Inspiron 17R 5720 doesn't work with charger. Charger is not recognized. Not charger problem.

Hi CJ777,
Thanks for reaching out with your query. You pretty much figured out all points of failure. Good job.
If the adapter is not detected in BIOS, it most likely is an issue with the mother board. In the BIOS set up, AC adapter should show up as 65w or 90w. If the adapter status is 'None' or 'Unknown Device Installed', it indicates that the mother board is not detecting the adapter for which the battery is not getting charged. Once the battery charge drains, I'm sure the adapter will not charge it again. Replacing the system board should resolve this issue.

I thought it must be the battery, so I installed a new battery. that did nothing to change the problem. So, I ordered a new motherboard and after a few weeks, I recieved it today, installed it, and I still have the same thing.

Hello! As the title says, I have an Aspire 7551 laptop--it's a bit old, so I realize that may be the problem, but I do want to troubleshoot before assuming it's just crapped itself.The other day, it stopped recognizing its charger. We at first assumed it was the battery, and bought a new one, but nope. Also tried 3 different chargers after that and still nothing. The new battery works, but but the laptop itself isn't acknowledging that there's a charger plugged in, and is running off of straight battery life. The physical laptop itself isn't particularly damaged, aside from general wear and tear from age, and the charger port seems undamaged.Any help would be appreciated!

My mother is having problems with her laptop, she said she could shut it down last night so unplugged it and left it over night, and today when she started it up everything was fine apart from a dark screen.

I have been on teamviewer trying to get to the bottom of it. Fn and arrow keys apparently adjust the brightness temporarilly but it just defaults back. I ran some windows check for solutions and it threw up this warning which indicates to me it could be a video card issue.

It also said something about Skype, so I updated that. I ran CCleaner and the SF_diagnostic tool. I have attached the zipped file to this thread. can anyone offer any insight to the possible cause of this because I'm stumped?STU9000.zip

I have just bought a new screen it is compatible. The old screen was defiantly dead screen wont show with torch. The new one I can only see with a torch, I sent it back they tested it said it was fine but still sent another. New one still the same can only see with a torch.
what else could be the problem? I have turned the brightness up I no it isn't that.

Ran into the same problem with an HP laptop several months ago, turned out that one of the wires supplying the inverter had worked loose from the plastic terminator.

So since you have verified that the screen itself is not the issue, it sounds like an inverter or backlight issue. This site helped me out with that laptop.

I can't believe nobody has asked this question before sind I have googled it and it does not appear that uncommon. I downgraded from Win10 and somehow I can't get the BIOS to give me options. The screen does not get a signal and all I get is a blinking power button. Here is what I tried: I disconnected everything - HDD, DVD, Power and removed the battery from the motherboard and waited 5 minand combinations of the abover connecting something :-) I believe I should reset the motherboard BIOS and frankly on the motherboard I encounter just three locations where I could manipulate things with jumpers. Is there a manual for the MB somewhere? A way I can flash a new firmware from a USB stick? Any trick to get the Monitor to show something?

Recently I bought a charger for my HP G61-110SA which was just a replacement adapter. Now yesterday it did something weird. Basically, there are two pictures of the two indicators there are to show whether it is charging, one is on the front and one is next to the port on the side. Basicaally the charger wasnt changing the indicator on the side or the one on screen but the one on the front was working when I turned it on. By default the laptop chages brightness when plgged in but now it sort of brightens a bit (not to the full level as should do) and then goes back to normal. Today the laptop is still doing the same but the front light now only turns on for a few seconds before turning off! I dont know whether it is charging. Is this the laptop or the charger. Any help would be useful, I have attatached the side indicator and the front one

UPDATE: I found a website which said you could turn it off and start without battery but with charger and then turn off and use both. However, I turned it off and removed the battery and it wouldnt charge. Then I put the battery in and it started charging-weird. Also the light on the front doesnt last very long so I am stuck. ANY HELP?

Just looking for some advice from you any clever electronics bods!

I have some superbright blue LEDs, rated at a maximum of 5.5V. I was going to run about 4 of them by connecting them in parallel, across the ground and +5V terminals on a molex connector from the PSU (And also through a switch installed in the front of my case.)
Is this likely to cause any problems? Do I need something to limit the current on each circuit?
Would I be right in thinking I could also run a few in series across the 12V rail? Would that be any better?

I have a laptop with a light surrounding the mouse touch pad.
Is there any way to turn it off permanently, without opening up the laptop and cutting the power to the LED?

Everytime I turn it on I have to use the keyboard combination Fn + F7 to turn it off which his very annoying.

Is there a way in Windows 7 that I could execute that command at startup?

You can see a picture of the laptop here:

This wouldn't be a Win7 function since this is custom hardware done by the laptop manufacturer.

The only thing I would suggest is poking around in the settings for the touch pad and see if there is a setting to disable the LED.

It's also possible that they hid the setting in another device too.

Unfortunately the only advice I can give you is to start poking around in the settings of the various devices.

As I was writing htis I also thought it might be in the BIOS of the machine. So, I'd check there too.

3. Change the color of the blue LED to a green LED that's not as bright.

You can not modify the firmware on an active cable modem without the cable company getting SUPER suspicious, you'd need to keep up on spoofing the correct firmware to the cable company and it becomes a huge mess.

If you have soldering skills, that is your only other way.

I hope that I am posting to proper forum topic here, but I just finished a new build with the following specs:

Asus P8Z77-V Mobo
Intel i5 3570K unlocked CPU
Xigmatek Durin D982 heatsink/fan for CPU
Asus video card - GeForce GT 640 (2GB DDR3)
16 GB RAM, Crucial Ballistix, DDR3 1600 (2x8GB)
CoolerMaster Silent Pro M 850w PSU
Toshiba 500 GB HDD 7200RPM SATA 6.0 gb/s
Asus DVD optical drive, SATA
2 case fans

In any case, my system is booting fine, and I just got Windows 8 64 bit installed, but my concern is that as soon as i flipped the switch on at the back of the power supply, it started up my fans, and both LEDS at front of case lit up. But I had not powered on system. So then i booted, and worked a little bit, and when I shut it down, the LEDS stayed lit, the fans still ran AND the fan in the PSU kept running - and did not stop until I flipped the switch at rear of PSU off again. The only fan that did not keep running was the CPU heatsink fan.

My case Fans are connected directly to the motherboards case fan connections. I have the PSU plugged in at both the 20+4 connection and the 12v 4+4 connection.

I don't know what other info you may need to be able to help me out, but does anyone know what I need to do to stop fans and turn off LEDs when I power my computer down? It is something I need to set in BIOS? I know there are a lot of power settings in there, but I figured I would ask first. Electrical issues are not ones I have any knowledge of....Any help would be great... Read more

Hi rather simple problem for some tech dedu to answer but here it goes.

After reformatting my PC because of freezing on the screen to select last good configuration of safe mode etc, I managed to get windows reloaded. I suspected a hard drive fault. 12 hrs later after a restart nothing would appear on the screen. I noticed both LEDs on the front case where on constantly. I have read somewhere before that if the load LED flashed repeatedly there either is not any ram installed or it is faulty. So what does the following indicated.

Power and H/D load LED's on constantly mean?

H/D has been replaced and same fault appears. Motherboard RAM LED is on.

Thanks for anyhelp you genious's can provide. Cheers.

David
 

A:Power + Load LEDs on constantly

Welcome to TSG!

There is no "standard" fault diagnosis indicated on PC's by the power and HD activity light.
There may be some on specific brands of PC's but nothing universal.

The power light is on because the power is on (nothing more or less)

The HDD activity light is on because the HDD thinks it's active, eithier because it is, or because it's dead, or because the cable is incorrectly attached, or because there is a motherboard problem or.... etc.

Does the PC POST (Power On Self Test)? e.g. show the BIOS boot-up sequence and beep prior to this?

Hello,
I was just recently updating my soundMax audio drivers (as my sound stopped working mysteriously over the past 24hrs) on my Asus P5B motherboard. I left the room momentarily and when I came back, black screen and pulsing audio blips/front LEDs. I powered down the PC, removed the speaker wiring and same thing. The green power light on the bottom right of motherboard is solid green, outside case power and HDD light pulsing on/off. CPU/PSU fans run, but surge with pulsing.

I have since tried a different PSU, unplugged all periperals, removed/swapped etc ram sticks, removed/cleaned cpu fan, reapplied heatsink, checked all cables....and still the same issue?

Did my CPU or MB fry? Would simply updating a driver cause this?

Upgraded my box a couple months ago.. Added ThermalTake TR2 600W PSU, GeForce GTX 550Ti PNY video card, 500G HDD etc. It's been running fine until the sound issue. Any Ideas? (hopefully other than buy a new MB/CPU??)

Thanks.
 

A:Pulsing Power and front LEDs..help!

Definitely strange. Though wrong drivers can damage hardware, theoretically, it is very rare and not likely if you used the correct driver and the sound worked.

It may just be coincidence. But I'd vote power supply before CPU or board. Try a replacement if you have one.

Of course, check all internal connections, cards, and RAM.

When approaching a 24 pin connector for the LEDs and power button and at the time of the act i thought it was one solid piece of connector and i could just pull it but when i pulled it the whole thing scattered.

(I'm writing this on a different pc so I cannot use TSG Info)

I woke my pc up from sleep state, as usual, and the blinking light on the case that is usually blinking when it's in sleep state was still blinking, like it wasn't all the way 'woken up'. Some regular lights that usually go on when it's awake went on but I could hear that the fans weren't totally spinning up. The monitor had not awoken either.

Then I noticed some red lights on on the video card, lights I believe are not usually on. So I'm thinking it's damaged or dead??

Hi, I bought a refurbished Lenovo ThinkPad model Z61t from a well known vendor back in May and it worked fine for several months but then just recently I tried to power it on and nothing happened. I assumed the battery was dead so I pulled out the power cable and plugged it in but I noticed that the green power & battery LEDs didn't light up like normal and when I tried to power on the laptop again nothing happened. I tried using a different power cable but it didn't work either. Since this unit was refurbished it only came with a 90 day warranty. I don't know what else I can do to get this laptop working again. Any suggestions?

For people who undestand circuit boards I did a test with a power tester and the yellow power connector on the back of the laptop. When the yellow power connector is not connected to the laptop motherboard my power testing meter shows ~20 volts but when I plug the connector into the laptop motherboard like it's supposed to be my power testing meter shows ~0.5 volts. Is that normal. Why would the output of the power supply drop to such a low level?

My hypothesis is also my fear; that the motherboard is dead.
 

A:ThinkPad Z61t no LEDs and won't power on :(

Im guessing also that its a bad motherboard or a power supply problem of some sort.If where you bought it is reputable and even though the warranty is gone hopefully they can make it right for you.Motherboards can be very expensive to replace. You have to decide if the computer is worth fixing or not depending on its age.Ive bought many lenovo and dell refurbished laptops and in theory if they were refurbished from the mfr they shouldnt have problems already.If the vendor refurbished it they should of made sure all was well before selling it. But to be fair things can be fine one minute and not the next.

Hi guys,

Got a Coolermaster HAF 922 and as is obvious, it's main light be red so I'd like some extra Red Cathode's because I'm sad like that

However, I can't find any that are reviewed positively as red They all say Pink, Orange etc.

This discounts the major brands I can find (Akasa, Sharkoon) and from what I've read they all suffer from this issue...

So it seems the solution are red LEDs! But again, I can't find any reviewed ones at all :-/

So I turn to your superior knowledge base

Hi, my dell E510 wont fully power up, when i turn it on the Dell screen pops up and loads up to about 90%, at which point it just freezes. My keyboard wont respond to anything. Ive trouble shooted it and after a while fiqured out that the front I/O board was bad (or at least thats what i thought). I just pluged in my usb wireless network card into one of the USB ports on the front and the computer powered up just fine. This worked a couple of times, but the problem came back. I decided to order a replacement front I/O board from dell, and when i received it i replaced it and it powered up fine the first time, but has not since.

I researched some more and tried to narrow the problem down and make sure it was the front I/O board. I did this by unplugging the computer, disconnecting the entire front I/O board, taking out the CMOS battery, and resetting the MB by using the CLR pins, reinserting the CMOS battery then plugging back in the power supply. The computer turned on by itself as it was supposed to, but the same problem existed (90% loaded on the DELL screen). This leads me to believe that the I/O board isnt bad, because if it was it should have powered up just fine, which doesnt make sense because when i mess with it sometimes it will work, but hasnt recently.

Everytime i try to power it up the front 1 and 4 led lights will turn green and stay green once the DELL load screen gets to 90%. Any Help is greatly appreciated.

A friend's Satellite Pro L650 having worked fine until yesterday, suddenly powered itself off. Now on startup, it will power on as normal for about 10-15 secs before powering off abruptly. On power off, the white/blue DC In LED and the orange Power LED both flash on an off together at about one second intervals. This powering off happens whether I let it boot to Windows or press F2 to go into BIOS setup.

I'm assuming this flashing is intended to serve as some sort of diagnostic code, but I've yet to track down what it means. Can anyone help?

For the avoidance of doubt, powering up without the battery produces the same, abrupt power off experience, except the two LEDs remain solidly lit this time. With or without battery, trying to power up again immediately after a power off produces no response at all. Removing the power lead and immediately reconnecting it again and then powering on produces an abrupt power off, but within less than 5 seconds of being turned on. The longer I wait between power on attempts seems to give a slightly longer powered on state, but without fail, the machine will just power off suddenly. Surely with the short "power on" times we're talking about, it can't be any kind of thermal cut out?

I had an old Satellite L450D lying around which coincidentally uses the same PA-1750 AC adapter but using it made no difference. Its battery of course will not fit the L650 !

So, to give some background, this is my first build, and it has been assembled and working for 4 months now with no problems. I was able to identify the original motherboard as defective the first time I was building it, and the new one has never given me any problems.

My parts are an i5 2500k, a Gigabyte 768 mobo, a Seasonic 750x PSU, a Gigabyte 6850, and 8GB of GSKILL RAM. And I have an aftermarket heatsink as well. CPU is not overclocked.

Essentially, I was running it overnight to patch a game, and this morning when I came to wake it up the monitor wasn't showing anything. Turned it on and off again, "no signal", etc. I tried turning on my sound and restarting the computer, and I didn't get the bootup sound, so I'm guessing my CPU is not booting at all.

I have run it overnight before with no problems, and as stated, I have an aftermarket heatsink and it's not overclocked. I would be very surprised if it overheated.

Also, normally when I boot up, the motherboard LEDs start up for a second and then turn off. Now they're just staying on- not blinking, just staying on. I don't think it's the PSU either, as it has more than enough wattage, but a failure is always possible I suppose.

I have not taken it apart yet- I'd like to avoid that if possible- but if you have any advice I'm willing to take it. Hopefully, if I can't resolve it, I can at least find out which part is the issue.

Thank you very much for your help... Read more

Hello I have quite a frustrating problem, last week on my last PC I was having problems with it slowing down in games even though it was more than fast enough to handle them, after trying to trouble shoot it, my screen randomly went black after I restarted it the front LEDs wouldn't turn on, my keyboard and mouse would not light up and the screen was black, though all fans would turn on, so I started to trouble shoot, I bought a new PSU, I tested my GPU in my roommates computer. And I replaced the ram with my roommates ram, I posted on other forums and they said it was likely my mobo or CPU, so I went ahead and used it as an excuse to upgrade, I bought a new core i5 4690k CPU and an MSI z87 mobo, put everything together and still the exact same problem. The only components I haven't replaced are the fans and my computer case / power button and audio/USB jacks. I don't know what to do now, could it be that there is something wrong with my power button coming from the case that is causing all this? (Note the front LEDs flash for a split second when I turn the PC on or off)
 

A:Solved: brand new PC won't turn on, fans start but no front LEDs or signal to monitor

My Elitebook Folio 1040 G2 is failing to start up.  Currently the AC adaptor is plugged in but the Power Button and Caps Lock leds are flashing white and the Battery LED is flashing orange. The battery is totally drained and the laptop will not start. Immediately prior to this problem I was running a scan on the laptop which was taking several hours and I noticed that the battery was not charging even though the AC adaptor was plugged in.  The battery level was 4% for a couple of hours and then the laptop turned off (I assume because the battery was drained). Based upon previous instances of this problem reported  on the forum I have tried the following removing the  AC supply and holding the power button and mute button for> 30secs removing the  AC supply and holding the power button and esc button for> 30secs removing the  AC supply and holding the power button and wireless button for> 30secs removing the AC supply and disconnecting the internal battery and holding  power button and mutebutton for> 3osecsremoving the two screws from the middle back of the computer base and then hard restarting In each case the flashing lights and failure to start remain.  I  am assuming the ac adaptor is alright as the flashing lights only occur when this is plugged into the laptop. Doesanybody have any ideas as to how this can be resolved? Regards          Rap...

Evening all, I just have a minor dilemma with the Sapphire Trixx software I have, or possibly even something else entirely. FYI, I've been using Crysis 2 as my main benchmark alongside 3DMark and Heaven DX11 since that game is quite power hungry with DX11 enabled.

Basically though, I have an HIS Radeon HD 7950 in my new system and for some reason the voltage being pumped into it seems to change by itself. I believe the stock voltage for this card is 1,087 under load, since hitting the reset button in Sapphire trixx always puts it back to this figure, and since anything lower causes Crysis 2 to crash within minutes on stock clocks when running it with DX11 & settings at full pace.

For some reason though even when I load a stock or overclock profile, apply and save it in Trixx, sometimes when I reboot my system the clocks stay the same but the voltage has randomly decreased to low 900's, which just isn't enough juice to power the card even at stock clocks.

I've been able to play Crysis 2 at the highest settings I can muster (1920 x 1200, DX11, High res and everything Ultra) on stock clocks with 1,087 voltage for several hours with no issues at all, and the same with my current overclock and voltage at 1,125.

It's worth me noting however, that this voltage decrease happens even when I leave the voltage at Trixx's "reset" value of 1,087 before shutting down for the night. I have disabled Catalyst Control Center since that caused a... Read more

A:Not enough voltage? on +12v

Hi waynosss,
what is generally accepted for a PSU in the way of tolerance is +/- %5 (12.6v - 11.4v) so if your 12v reading is being reported correctly, your 11.19v is indeed low and out of the acceptable tolerances.
i would try another program to back this up(assuming you do not have the equipment to test yourself) to confirm. your 5v and 3.3v readings look good.

Is there any way to get the safe operating voltages for P4 478 pin, DDR PC3200 ram and graphic cards (agp X800XT in particular)? I think I need more voltage on my ram, but I don't dare go any higher....
 

A:Max (and maybe min) voltage?

Dunno, here?

Else, search for the P/N of the part and it should be in the specs.

I have my Celeron Processor overclocked (see signature), and my BIOS gives me the option to change the cpu frequency so I could overclock higher. The option right now is set on "normal", and I wanted to crank the fsb to 160 (now at 155) to make 3.2 ghz, although the system becomes unstable. The voltage options list (besides normal): .01, .02, and .03. What should I do (if anything) to the voltage? Also, I have an option for changing the dram frequency (changeble in speeds of mhz). I have looked onling to see what the dram is, and I have figured out it has something to do with the ram of the computer, although the website I was on only gave ratios; what does this option do?

speedfan is telling me that the +5 volt line works at 6,85volt.if i measure the voltage on a molex with a voltmeter in the +5 volt position the result is +5,17.which one is wright ?do i need to replace the psu ?
 

A:PSU voltage

What are your other voltage readouts? I don't use speedfan so I can't comment on its accuracy but I do use a multimeter. If speedfan is correct then you definitely have a problem but if your multimeter is correct you are fine. Below or above 5% of the set voltage setting is when you need to become concerned

Test your other lines and do a comparison.

Interpreting your results
The general range of safe voltages is as follows (plus or minus 5%, according to the ATX standard)
+12v rail (11.40v - 12.60v)
+5v rail (4.75v - 5.25v)
+3.3v rail (3.13 - 3.47v)

Just because it's within that range does not mean it's doing its job.

Hi Everyone

I have recently built a new PC for a friend made from the following:

Kandalf LCS Case (the one with built in liquid cooling)
Thermaltake 520W Power Station Modular PSU
XFX 768MB 8800GTX Graphics Card
2 GB (2 x 1GB) Corsair Dominator DDR2 6400
2 x SATA DVD-RW Drives
2 x SATA 320GB HDD's
1 x SATA 400GB HDD
ASUS P5N32-E SLi Motherboard
Intel E6600 DUal Core Processor

The problem is the machine kept shutting down. I looked in the bios and the 12v reads 0.0. I put a new PSU (Hiper 580W Modular) and the 12v worked for a few minutes and then returned to 0.0

I tested both PSU's in another PC and both worked fine (used Speedfan). Why would the new PC stop the PSU's working?

Any help much appreciated

Thanks

Hey i was just wondering because my comp keeps freezing or restarting randomly and i was thinking that it was my power supply which is a Solytech 460W. Anyways i got this info from the bios

from the 3.3V its drawing 3.31V

from the 5V its drawing 5.02

from the 12V its drawing 11.96

I was wondering does this have nething to do with my problems or is it something else?

A:my cpu voltage

As a general rule, no. Gradually bring up the frequency, and run a torture test (Google Prime95). As soon as you fail a test, try bringing up the voltage slightly.

Be careful. I know someone who fried his CPU/MB increasing the voltage too much.
