LAPTOP BLACK SCREEN (power + fan OK, HDMI to TV OK, touch screen OK)

Q: LAPTOP BLACK SCREEN (power + fan OK, HDMI to TV OK, touch screen OK)

Hello,
I have a Sony Vaio T-series laptop (model SVT13126CXS) running windows 7. As of yesterday the screen is black...it doesn't display anything.
Laptop powers on (lights are on, fan makes noise, etc.).
I was able to plug an HDMI cable from my laptop to my TV and I am able to use the laptop using my TV screen (laptop screen is still black, but displays on TV works).
And the odd twist... this is a touch screen laptop, so I am able to touch my laptop screen and it makes clicks and moves cursor on my TV. (for some reason, the track pad doesn't work while its on TV display though).
Any help would be greatly appreciated. If you can give me steps into diagnosing the problem, that'd be great!
I live in a small college town and there is only one computer repair shop and since it's a monopoly he rips people off. Charges $95 for a diagnostic (if you get it fixed, it goes towards the repair; if not, it's $95). Charged my friend $120 for macbook charger and it wasn't even an genuine Apple product!

Hello,

My laptop's screen goes black when I connect it to the TV via a HDMI cable, however this is completely new as it used to work fine. I can still watch things on my TV but I have to look at the TV screen where text comes up quite small and it makes it hard to do stuff, so I was wondering if anyone would know why my laptop's decided to start doing this, and how I can get it back to both screens working at once? The volume and everything else works ok, it's just a bit annoying is all!

I have Windows Vista Home Edition, not sure of the details, but I got it just when Vista first came out.

Thanks!

Hi we have a compaq laptop that is about 5 years old. It's a basic laptop and was quite inexpensive when we purchased it. I think it was like $300-$400. Anyway, we had a power outage and now the screen is blank (black to be specific). When I turned it on the lites flash and it sounds like its running, but nothing, I mean nothing shows up on screen. My question is what could be wrong? Would it be worth paying someone to fix it? Do you think I lost the pictures downloaded on the laptop? That's the only data I care about recovering! Thx in advance for your thoughts.

Hi Guys,

Im having some problem with my Packard Bell EasyNote TJ61 - I powered it on and the fans whirred like normal and the lights on the keyboard came on like normal - the power button lit up. But the screen stayed black. Then the fans went silent after 5 seconds and it sounded like it was switched off but all the lights were still on - the power, hard drive and keyboard ones. I noticed if I run my finger over the touch pad buttons for volume etc they light up so im not sure whats wrong.

I replaced the screen on the laptop the other day and it was working fine until last night and this has happened. Any suggestions?

I've tried replacing ram / replacing hard drive / pulling the cmos battery for 30mins / unplugging and trying the 30 seconds power button trick but nothing.

Any suggestions?
 

A:Laptop Power On - Screen Stays Black - Fan Goes Off 5 Seconds

If you have a PC monitor connect it to the laptop and see if you get a display on it.

Also check the laptop screen for a dim image, shining a light onto it may make it more visible.

What was wrong that made you replace the screen ?

Hello all,
I am using a dell studio xps 1645 with ati mobility radeon HD5730 inbuilt.

Problem i have been facing past few weeks is that my laptop screen is going black and is crashing a few minutes after booting up when i connect to ac power.

I did a few diagnostic tests. It is working perfectly in safe mode. It is working perfectly when i disable my graphic adapter and boot in normal mode. The tricky part is that it works perfectly with graphic card enabled when im using with battery. As soon as i connect AC power it crashes with black screen in a few minutes/seconds. I also uninstalled and reinstalled the graphic drivers and BIOS is also up to date

I recently updated my graphic card drivers but still it worked well for a few days. I could play games with no problem at all.
I used to have a heating problem aswell. The screen would lag and audio would distort. I have cleaned my heat sink now but cannot test it out as my laptop crashes. Also my battery is pretty old now and gives only 30 min backup.

Any help would be much appreciated

2. So you never see a thing on the screen? If this is true, the video chip might be gone.

3. If a computer shuts down, 90% of the time it is due to a heat issue. How old is the laptop? Has it ever been cleaned of accumulated dust?

Yesterday I was on my laptop and before I shut it down it went into what looked like a different mode. I booted it up this morning and it is still in this mode. It looks like touch screen mode but I do not have a touch screen.  The icons on the task bar are spaced out and there is a back button on the task bar too which is not normally there. When i right click against the task bar, one of the buttons says "Show touch keyboard button".  All of my files are spead out as if to have room for touching if I had a touch screen but I do not. I am finding this very annoying because I cannot get onto my desktop properly and is not in the right mode. Please help!

Hi Lenovo Forum, Yesterday when I started my computer it showed the lenovo splash screen and the screen then turned black and nothing happened. I tried restarting the computer etc. but nothing seemed to help, so I decided to do a complete reinstall of Windows 10. Everything went fine until Windows Update installed the Intel® HD Graphics 4400 driver. About 80 % into the insatllation it plays the windows sound of something getting unplugged and the screen turned black (like before the complete reinstalllation and format). I have been able to get into the computer again by forcing it to shutdown and turn it on in safe-mode and disable the Intel® HD Graphics 4400 driver. I have tried to install an older version of the driver but it did not help.Therefore I am asking all of you if you have experiened anything like it and if you have a solution? Best regards,Rasmus Villebro

Recently I bought a new Full HD TV, it's a Samsung LE40B530. I'm trying to get this TV connected to my Compaq Presario CQ50-100ED laptop from hdmi output to the hdmi input on the TV. The videocard is a GForce 8200M. The latest drivers are installed.

The problem is that when I connect the two, the laptop screen goed black and the TV says 'No signal.' Pressing the FN F4 does not work. Also I'm not able to get back into vista on the laptop. The screen stays black even after unplugging the HDMI cable. I have to hold the power button to switch the laptop off. Not a good thing.

Hello and thanks for reading,

I have a 2 year old HP pavilion dv6 series laptop running windows 7. Yesterday I turned it on and it started normally but when I tried to browse on Firefox it gave me the blue screen (for the first time ever) and it shut down. Fearing I had a virus I ran it in safe mode and started a scan and began transporting my pictures via Dropbox just in case it died on me. Sure enough a weird error message (couldnt figure out what program made the message pop up) popped up saying I had a bunch of urgent viruses.. I didn't click on it at all and before I couldn't think of what to do the blue screen popped up and it shut down. When I tried to restart it the HP splash sign popped up and the screen flickered black and a blinking cursor started in the upper left corner. So this is where I stand now... Black screen with blinking cursor. Set default setting in BIOS (didn't work) and F8 (safe mode) or F11 (system restore) does nothing... The black screen just stays there. Any ideas? Is it a gonner? I'm hoping to get back on and get my pictures if possible. Help please!

I recently did a factory restore on my laptop since it was giving me really bad problems before(BSOD on boot, unable to start in safe mode, etc). I assumed that it was caused by a bad video driver installation. Once I did my factory restore, this problem was solved, but it seems like a new one arose.

In the first few days the laptop was working fine, but I recently realised that if I unplug my AC Adapter, my laptop would work for awhile but will eventually die. The screen would just go black, then I would see weird colors and then it would go black again and I would be forced to hold the power button and restart. The funny thing is, this never happens when I have it plugged in.

I then realised that it happened when I plugged it out and moved it around, so I assumed it had something to do with the wiring inside my laptop. But it seems that isn't the case since even if I move it around while it's plugged in, it doesn't happen. I'm pretty sure it has something to do with my power supply at this point, but I'm not really sure.

If anyone can help, I would really appreciate it!

EDIT: It just happened to me as I tried to access my task manager. I did CTLR+ALT+DEL and my screen went black, and my laptop simply restarted itself.
 

A:Laptop screen failure; random colors followed by black screen

EDIT: It seems it has gotten way worse. It happened while it was plugged in, and not only that, but when I tried to turn on my laptop again, the screen remained black and I heard these beeping noises. (6 beeps in succession, over and over) Sometimes I turned it on and it didn't even beep. I managed to actually get my laptop to boot, but I'm afraid it will happen again.

Hi, I just got my Thinkpad P70 4k with Nvidia Quadro M3000M graphics this week, running Windows 10 Pro.I have run into a lot of issues regarding HDMI output - switching to discrete graphics disables the HDMI output and i can no longer change the resolution or scaling (nor does the Nvidia Control Panel show up). In mixed graphics mode the HDMI output works, and i can change the resolution  but after waking from sleep the image only shows on the external (HD display) connected over HDMI.I have to disconnect the HDMI cable to get video on the laptop screen and the reconnect it to get video on both screens.I suspect that the Intel Graphics runs the Laptop Screen in mixed graphics mode, in the Nvidia Control Panel I can only control the external display.    I am running the latest BIOS (2.03) and updated the Nvidia Drivers directly from NVIDIA (10.18.13.6256).  On another note I also had a black screen issue after updating the BIOS to 2.03 (no idea what version came installed) everytime i rebooted and had to disconnect the Bios Battery twice, but that somehow (??) got resolved after taking out a SD card from the Card Reader.

First post, but I have tried to uninstall video drivers, system restore, random registry fixes, and so forth. I also did a virus scan, showing 17 Trojans (I know, very bad). I am guessing that is how this happened, not sure though. Uninstalling the video drivers helps, until I need to restart it due to new software. Then I can sometimes get to the log in screen, but even after that, It just goes black after a few seconds. I have searched and searched all over, and have not found a fix. Any help?

I'm having a weird problem. My laptop will show a black screen when booting. It seems no matter how long I wait, nothing happens. When I attach an external LCD to the laptop, it shows the Windows load or Windows resume graphics on the external monitor, but not on my laptop screen. As soon as the Desktop Screen with the Windows Login appears, it then appears on my laptop as well.

I also can't seem to get to safe mode. I push f8 and it never comes up I haven't installed any new software or hardware to cause this.

I did two things to fix; First I lowered the resolution to 1280x1024 and it worked, but that drove me crazy, so I bought a Intel card with 1gb of video memory, which I'm told is the minimum one should use if one wishes to use HDMI HD 1920x1080. It probably would have worked fine with an ATI as well, but with at least 1gb of RAM.

The card I bought was a Gigabyte GTX 450 and I might have been able to go lower, but since it was only $90 I figured it was worth it.

If you have a card with 1gb perhaps you could give that a try, or try lowering the resolution and (maybe), color depth.

The machine in question was Windows Server 2008 R2, but hey, it's essentially the same as windows 7.

Just my 2 cents worth.

The problem started as a HDMI-cable was plugged into my running Satellite T130-17E and the screen was closed down. From that point the notebook screen stopped working. When booting the windows start-up logo is on for a couple of seconds and just before the entering the desktop the cursor is visible on the screen. But except from these short moments there is no action on the notebooks screen. When I reinstalled the driver to the graphic card there was some short moments (less than 0,5 sec) when the screen was active.

I can use the notebook without any problems via HDMI to my TV. And when I adjust the screens brightness (FN+F6/F7) the black screen can get more back-lighted.

When I turn off the HDMI-output or plugs it out - nothing happens on the notebooks screen.

Can some of you please try to help me out as I really need my notebook to work normal again. If you can help me sort out this problem I'll be very grateful-

Kind Regards,
Jacob Lindberg

A:Satellite T130 -Black screen- HDMI works perfectly

Hello Jacob

Start your notebook with HDMI cable and wait until windows is fully loaded. When you see the desktop on the TV use FN+F5 key combination and switch to the LCD back.

Can you do this?
Does it work?

Hi there
I see more and more laptops are being sold now with Touch enabled screens -- Now using a laptop in the Classical position I.e with the screen at RIGHT ANGLES (Vertically) to the desk what possible use is touch.

Now if it has a detachable screen or can work in Tablet mode (as a convertible) that's fine but as a standard laptop -- what would you USE the touch facility for even if you were running Windows 8.

Touch is fine on accessory devices such as drawing devices which you would have placed HORIZONTALLY on your desk or if you were using "Electronic Drawing table" type devices - but on a bog standard laptop screen. But on a standard Laptop. ?? - Maybe on a Train / Plane if you were using the computer as an e-book reader - but if you just wanted to read would you be using a computer anyway -- e-readers are ridiculously cheap now.

All it does is just push up the price of the laptop for NO BENEFIT WHATSOEVER.

Am curious - anybody here got a laptop with Touch - and what are they actually using touch for.

Cheers
jimbo

A:What use is TOUCH on a laptop screen

I totally agree with you jimbo. I bought a new laptop a few weeks ago and specifically looked for one that did NOT have a touchscreen. I tried out the touchscreen models in the stores and decided touch is not a good interface for larger screens. Works great on my phone and tablet but requires too many exaggerated arm movements on the larger screen. Constantly moving between touching the screen and going back to the keyboard was a pain as well.

hey guys, im thinking of getting a laptop with a touch screen, and i was just wondering if there is any way to also hook it up to a normal pc and use the laptop as a tablet?
 

A:touch screen laptop capabilities

The only "touch screen" laptops I'm aware of are tablet PCs. You don't really hook them up to a "normal" computer. A tablet PC is a computer unto itself. If you just want to use the tablet interface to enter input on another computer, I can't think of a way. The input-related software and drivers have to be running on the tablet itself. You can buy separate tablet hardware for connecting to any type of computer. That would be far more effective and cheaper.

Touch screen began to experience phantom touches in the lower and upper right hand corners of the screen. It interferes with the use of the laptop entirely, preventing me from even turning off the drivers to disable the touch function of the screen. I can only power the laptop off by pressing and holding the power button for several seconds. On reboot, PC behaves normally for up to 1 minute until phantom clicking resumes.  I would have have emailed support directly, but it seems I have no options but to call, which will not resolve my issue.

Is this correct, and if not what would you recommend instead?

Hi, my laptop running 8.1 (came with 8 from factory, updated when 8.1 came out) was updated a couple of days ago, through an official prompt. Since the restart, I am getting a Touch Keyboard icon on the taskbar, Office apps have a touch mode and the pointer keeps disappearing. It never did this before the update. My laptop is NOT touchscreen, it is a series 5 Samsung, I don't mind the new icons to be honest, but can't stand the pointer disappearing and having to reboot every time. Any ideas as to why it happened and how I can fix it/avoid it in the future? TYIA

A:Laptop thinks it's touch screen after update

If you go to the bottom left of your screen, right click, then click on system, does it say that there is pen and touch support?

Also go to Device Manager, and check to see if there are any Pen and Touch devices installed.

If you can, post a screen shot of your device manager, Your system Window, and your desktop, that will help me, and others to find out the problem to this issue.

Its strange if Windows has loaded drivers for a device that isn't present, or installed the wrong drivers for a device on your system.

Why? because my Samsung ATIV Book 9 plus screen has a slight crack, I mean barely noticable, but it totally wrecked the touch screen as in it starts to freak out. little circles come up on it as if it is being touched and so, it seems when I disable the touch screen that does not happen. But when I restart the computer it enables itself. Also sometimes it enables itself in the middle of the computer being on. I have gone to the Human Interface Devices and even clicked on the uninstall of the touch screen, but it installs itself right back in minutes. I can disable it, then if I restart, it is enabled again. And it can mess with things when it is enabled as it starts flipping out.

So, I want to be able to have it permanently disabled somehow. Is that a possibility? and it is incredible if it is not. I do not want to spend for a new laptop screen. The crack is barely visible, actually, but it is there from top to the bottom of the screen but barely visible.

A:I would like to permanently disable my laptop touch screen

Using Autoruns, you have to hunt down all the EXEs, DLLs, etc etc etc that involve the touchscreen operations, and disable said files. I did that for my extra antivirus program [now mummified] -- and it has not come back to life since then.

I'm looking for a desk top replacement. I'm pretty much decided on Windows 8 touch screen, on the reasoning that touch screen appears to be the future and Windows 8 is designed for touch screen and should only get better.

I use my computer virtually all day everyday and want a machine that I can use in my home office in the day and also take into the lounge in the evening to use while my wife is watching TV or to pick up during commercial breaks if I'm watching TV.

I use it for ebay (work), general browsing & email, a lot of listening to music and watching HD video - youtube, i-player etc, a lot of photoshop & occasional video editing. I'm not a gamer at all.
I want a laptop with a large screen that will do what I want with power to spare.

With all that in mind I have narrowed it down to theHP touchsmart 17-j011sa from John Lewis (http://www.johnlewis.com/hp-envy-to...-1tb-17-3-touch-screen-natural-silver/p764544)

I can't find much info in terms of reviews, either pro or user for this particular model, other than the 2 reviews on the John Lewis site, both of which criticise the quality of the keyboard, the feel of which is probably not that important to me as I'm not a touch typist - although obviously I don't want the keys to be falling off.

do you need a firewire connection at all for any video you have ?

A:Y70-70 Touch Laptop (Lenovo) Screen flickering

Hi there, Mons   -
 
Thank you for writing in to the Lenovo Forum - happy to have you here today.
 
To fix the flickering problem, you should first check the laptop cables for loose connections. So engineer have already diagnosed and confirmed, it was not the lcd cable which is faulty.
 
Another possible reason for the flickering problem in computer screens is interference of magnetic fields from other gadgets. Yes, check if near your laptop, you haven't placed speakers, fluorescent lights, cell phones, radios and any other electrical device. If it is so, you must remove any such interfering electrical gadgets away from your laptop. Studies have proved that cell phones do cause screen flickering.
 
Try and identify when you face this issue, when on Battery power, mains AC adapter or in both scenarios? Is it for a particular power plan or for all power plans? Also check if this happen when you enter BIOS and in Safe Mode too.
 
Please follow the below steps:

If updating video drivers does not help, uninstall and reinstall the Video drivers.
Open Control Panel\All Control Panel It ems\Power Options\Edit Plan Settings and restore the default power plan settings by clicking on Restore default settings for this plan. Do this for all your Power Plans.
Change the refresh rate and see if that helps.

Update us how it goes.

Someone else already posted this same question and never replied to the person asking questions.  So here's my attempt. I have a HP ProBook 450 G2 with the i3-4005U processor and it does not currently have a touchscreen.    I would like to consider adding the digitizer which I am finding for sale online, but I cannot tell whether or not it's just a matter of buying the digitizer or if the whole display would need to be replaced. This is the digitizer i was looking at (or a similar one):http://www.ebay.com/itm/New-HP-Probook-450-G2-Laptop-Touch-Screen-Digitizer-Glass-15-6-69-15I05-T02-... My Product Number is L8E08UT,  printed under the battery. Also,  second question related to the first.     If I can just install that digitizer, does it rely on the LCD Panel being the 1368x768 resolution?      I was contemplating upgrading to a 1080P panel from LG instead like others have done.  (I know this is completely unsupported, just not sure if the digitizers were resolution specific) Thanks in advance! Brian

For a whie now my laptop has been randomly turning itself off. And while the screen is black it will then what seems like turning on, will start to make the loudest fan noise (sounds as if it's overheated - but it doesn't feel overheated at all). It will continue to do this until I hold down the power button and then restart it again. Sometimes it will start back up normally, other times it will go straight to the black screen loud fan noise when I press the power button. I've tried to start it up without the charger plugged in and it will still shut off and do the same thing; this also happens when I try without the battery attached but just the charger plugged in. My laptop can then go days without this happening, everything in working order and then out of no where it will decide to do this. It's starting to become very very frustrating since I have important exams coming up where a dying laptop is not ideal!  Someone please help this poor student out!

I purchased my Laptop 8 months ago with Windows 8.  Worked perfectly. Upgraded to Windows 10 after 1 week, and still worked perfectly for 7 months.Now the mouse and the touch screen does not work properly.If I hook up external mouse, it works perfectly.Tried to resolve with HP support, but after getting cut off on the support line 3 X finally talked to support who said it is a Windows 10 issue with their drivers, even though it worked perfectly on Windows 10 for 7 months.Told me it is not a hardware issue, even though it obviously is, works perfectly with an exteranl mouse, and that I would have to pay $100 for him to supoort looking at the OS Drivers.Should I do a wipe, re-install Windows 8, and then phone to get support since HP will not support any issues if you are running Windows 10?Thank you

I tried connecting my computer (laptop) to my 47" philips tv and i get picture fine but no sound to my tv and it would be nice to get the sound through the tv instead of the laptop speakers.

A:No sound when using hdmi with flat screen tv on laptop

The video output is what normally goies to a monitor...did you make a sound connection to the TV?

I've seen an NVIDIA laptop use a "Resize Screen" program that works majestically. Unfortunately, I do not have a laptop with an NVIDIA graphics card (It's a Radeon, I think...in a Sony VIAO). Is there a program out there that will resize a screen to fit the TV? As you might have already guessed, when I use an HDMI cable from Laptop to HDTV, the screen just doesn't fit properly! Annoying...
 

A:How to resize screen? (Laptop to HDTV w/HDMI)

Well there is a chance that your computer does not have the right resolution for your tv... but...

See if you can't make that work for you.

Hello friends, I recently got the Gnome desktop environment on the Ubuntu Software Center, and I used the gdm and startx command as said by another forum site. Nothing wrong, they said to logout, tried to login again, goes to a black screen and sends me back to the Ubuntu login screen. Tried again, same result, panicked. Looked up video tutorial on how to fix it, they said to access the control panel via ctrl-alt-f1 or f2, went to a black screen, no text at all, computer runs fine, no crashing. Is there a special way to access the terminal in a System76 computer, I really don't know very confusing? Is there a way to login with the guest session? I use Ubuntu 15.10 Wily Werewolf on my laptop. What causes this, I read on Ubuntu forums it's driver issues with Ubuntu and Nvidia, but I have my suspections with the Gnome desktop environment.

Hello everyone.

Since I bought this computer, I can't see the loading screen for Windows XP when starting the computer. It doesn't output ANYTHING until windows has started.

If i press F8 or F2 or stuff to change the settings, the screen is still black and the screen NEVER starts because it never gets to Windows.
This is not very good, for example if i need to change some settings or something.

I don't know what is the problem.. But maybe someone here knows?

Here are some system info:

AMD Athlon X2 Dual Core Processor 3800+ 2,01 GHz
ATI Radeon X600
1GB of RAM.

Hope there is anyone out there (maybe even with the same problem) that could help me
Thanks in advance.
 

A:Black screen on initial power-up

Hehe it's just me that is stupid here... I found out what the problem was.

I plugged in my old monitor (it uses a VGA-cable). And it worked.

My new monitor uses a DVI-cable.. But it seems as the VGA is set as the primary display when starting up windows.

Anyone knows how to change this, so that it makes the DVI to primary? I dont know a **** since im a noob on computers

Thanks in advance

I went to use my laptop and it wouldn't turn on, the only thing that was running was the fan and it was much louder than usual. When I returned to the laptop a few hours later, the fan was finally off and the computer was unresponsive, no lights or sounds at all. I tried the hard reset and that didn't work. I tried numerous outlets and still no power. What else can I possibly do?

A:Black screen, no lights, no power

Hi @hotpops, May the Forums be with you! It is a great place to find the help you need, from other users, HP experts and other support personnel. I understand that the computer youare using will not start properly. I am happy to give you a hand with this. As a start, please post the full product number and operating system in use on your computer. See the following, if you need help with that information.How Do I Find My Model Number or Product Number?Is the Windows Version on My Computer 32-bit or 64-bit? But for now and assuming that you are running either Windows 8.x or 10, try going through this document: HP Desktop PCs - Computer Does Not Start (Windows 10,8). Just read through it very carefully, as there are parts that apply to desktops and often a link to follow for an All-in-One. Please let me know whether that works for you, and if it does resolve your issue, please mark this post as a solution. Kudos would also be appreciated.

Can any one help with my start up problem?

For my desktop pc I have a power and boot up problem that does like this……….

Turn on main front power button

BIOS screens run through all OK

Windows startup screen runs OK (with the flashing green/yellow bar)

Then what normally happens is a pause of one or two seconds before the Windows iconappears and I can login.

What has been occurring recently is at this pause, the screen stays black and the computer goes into what can only be described as a low power mode. I sense this as the fan speed reduces, sometimes uneven and the screen stays black. Nothing else will happen.

BUT if I turn the pc off at the main power button at the rear and switch on again it will boot up, all through the processes with no problems. However if I do this at the stage above I have effectively forced a shut down and Windows enter via ther ecovery, but this still works fine. Windows etc works then with no problems atall.

Also if after shutting the PC down correctly I turn off the rear power button and turnit on before start up, all starts OK.

No devices are connected and powered on at start up other than Netgear router. I have disabled the devices (Control panel, Device manager, Properties) to “wake” the computer (mouse and keyboard) and also the Network Adapter, all of which were causingp roblems in waking the computer. This was a while ago and has been working fine for many months.
