Screen fades/blanks out

when i wake up my computer the screen will come to life and then go blank. the computer is still on because i have to manually turn it off and restart. sometimes it takes a couple restarts to get it back. Once it faded out but most of the time it just goes black. Any clues as to what is going on? Anyone??

Does it only happen with Microsoft Office applications? Sometimes this can also be caused by a memory leak, occupying lots of system resources to the point that Microsoft Office needs to 'queue' the text up in the buffer for display, hence the partial blanking.
Check you task manager - does the Physical Memory Usage exceed 85%?
Rather than using System Update to check for the graphics driver update, go straight to Lenovo's support site to get the driver from there. There are some times where system update doesn't display updates when there's actually one. Compare the driver version on the support site against that in the device manager's display card properties page, and update if necessary.
If you are using Firefox Developer Edition without e10s (electrolysis mode) and running some flash based app memory leaks can be very common. There is currently no solution to this issue, there are workarounds however. Either don't run any flash-based apps, don't run Firefox Developer Edition at all, or downgrade to the stable release of Firefox.
Let me know if this helps, please mark the respective posts s a solution IF it has helped you to solve the problem. This will make it much, much easier for others encountering the same issue to get to their answer, avoiding any duplicate queries.
Thanks!

Screen continually blanks out

I have a 20GB ipod, about four months old. Recently the screen has started blanking out randomly, and for long periods of time. It still plays music, but is practically impossible to use because the screen is so unpredictable.
Could it be something to do with the battery?

I've just noticed in another topic that the DVI output from Macs is 'exclusive' to Apple Cinema Displays, and can only be used with third-party display via a DVI - VGA adapter. This would make sense in relation to the other post on this subject elsewhere, where the poster talks about resolving the problem with the VGA adapter, although he thought this indicated the DVI cable was dodgy... I've not seen this issue coming up in any other discussion/post here or elsewhere where various third-party (and Dell) displays are discussed.
In addition to the circumstances listed above in my earlier post, I've now noticed that the problem is at its worse when viewing a web page with Flash content - constantly updating/changing animations and effects...
Any thoughts?
Thanks

Xperia Z3 screen continually blanking out

I was half way through writing a text message the other night and my screen had what could only be reffered to as a brown screen of death. I force restarted the phone and the Sony logo would start up before it went straight to a black screen. I could tell there was a back light behind it though. Eventually after turning it off and on about four times it started normally and I didn't have any further problems... for 24hrs.
When my alarm went off this morning I had the same screen of death and was only able to turn off my alarm by force restarting my phone. Now when i restart my phone I can usually get it to turn all the way on but then it randomly 'blanks out' after a few seconds. When this happens I can continually press the power button to get me back to my lock screen. Sometimes the screen will stay active long enough for me to unlock the phone, occassionally long enough to even read or write a message, but always, whether it be after 1 second or 20, it eventually blanks out where I can eventually start from the unlock screen after continually pressing the power button.
In a word, it's infuriating. I have already had to deal with two broken screens with this phone (both whilst just sitting in my pocket) that have cost about $350 each to fix and now this. I am definitely never going to buy Sony again however I need this phone to last until the end of my contract.
Does anyone have any idea how to fix this without having to be without a phone for up to 5 weeks??

Tapping iPad (3) causes screen to blank out

My iPad(3/iOS~6+) has a really weird behavior: If I tap it in certain ways that are a little hard to describe -- for example, puttig ti down on a table, even really gently -- the screen blanks out! It still seems to be backlit, but nothing shows up on it. The machine is still on; the sound works fine and siri answers and works fine, but the screen is simply black! The only way to get it back on it to either hard-boot it, or, interestingly, to close and then re-open the magnetic cover. Is it possible that whatever it is that the magnetic cover triggers has become loose and is triggering when I tap it in certain ways? What should I do? Should I have the screen replaced?

The Basic Troubleshooting Steps are:
Restart... Reset... Restore from Backup... Restore as New...
Restart / Reset

If you try all these Steps and you still have issues... Then a Visit to an Apple Store or AASP (Authorized Apple Service Provider) is the Next Step...

Full screen preview blanked out in from options in audio video settings?

Hi all,
Am running FCP6 and have lost the option to preview fullscreen in the audio video settings menu. It is literally missing, as an option, though the space the option inhabited is still there. Only options I have are to preview via firewire to my CRT monitor. I have tried to refresh AV devices and all frames, but doesn't seems to help/work.
Any suggestions?
Many thanks,
-Tom

Hi David and thanks for your suggestion. I gave it a try and no luck. Its just the same. I have no options in video playback at all unless I connect my deck and then I have only the via firewire options, the deck provides. BTW, I know its the wrong forum, but I have the same blanking out situation in the output filed in MOTION.
Any more suggestions would be greatly appreciated.
Thanks,
-Tom

Screen keeps blanking out

I have been experiencing a problem with my screen completely going blank of its own accord. I can still very faintly see the screen when it does this and the computer responds normally to commands. Using the brightness control button makes no difference (although I can faintly see the control responding on the). Putting hte computer to sleep and then waking it up sometimes helps, but only for a short period.
There are a few factors that seem to influence when this happens.
- if I plug anything into the USB port, it is guaranteed to dim
- The problem has only been occuring since I bought a new battery last week
- It doesn't happen when I have the computer plugged into the mains, only when I am running from the battery
Any ideas of what is causing this?

Might be your inverter board. Read this post:

Macbookpro screen blanks out momentarily?

My macbook pro screen momentarily blanks out, then comes back on. It happens very quickly, if you blink, you could miss it. It is almost like it is "catching up". This happens even on the home screen, when nothing is running, so the system is not being tasked. The system responds normally, no sluggishness or anything, the screen just blanks out, then everything is up and running as if nothing ever happened. It is unpredictable, meaning it does not occur "every three minutes, five minutes, etc". I can say it happens probably once every ten minutes, but not on a regular, predictable pattern.
Any thoughts or suggestions would be appreciated!
Thanks!

Hi @N_K_1660 ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion 15 Notebook and issues with the screen going black while playing videos. If you adjusting the Sleep settings in Windows 8 sleep options , this should help.
The section Enabling Away mode when sharing media files in Windows 8 will help as well.
Thanks.

How do I play a video in full-screen mode on one screen of a dual-screen Windows 7 system without blanking out the other screen?

How do I play a video in full-screen mode on one screen of a dual-screen Windows 7 system without blanking out the other screen? Not losing the other screen would be useful as I would like to, for example, monitor my emails whilst watching a video or to work on a project whilst watching an instructional video.
Note : Resizing a window to fill the screen is not acceptable as it still leaves unsightly borders.

[Solved] Screen blanks out after quitting X

Hello everyone.
I don't use any login manager such as GDM or Slim, I just start X from the terminal when I need it. However, after installing Arch the last time (new hdd), every time I exit X (XFCE 4 is my window manager) the screen blanks out. I know the system is still responsive, because if I type startx or reboot, it works. Calling startx wakes the monitor again. However, I don't need X all the time, sometimes I prefer not to use it.
I haven't dealt with this before and searching for a solution didn't help - nvidia users used to have this issue until a particular driver update.
However, I have an ATI card (HD 5750) and I use the xf86-video-ati driver.
Appending vga=773 to kernel options changes the resolution (of my ttys) but it doesn't solve the issue.
I'm kind of clueless about how to proceed, so any hints and tips would be welcome.
Thanks

The catalyst driver doesn't have the issue, so as far as it works, the issue is resolved.

Having an intermittent issue where my iMac blanks out on me. On restarting I get several bands running down the screen with pixels jumping around within the bands, then the white screen of death and nothing... This happens intermittently and usually restarts OK. Happened again three days ago and wouldn't restart for two days (again the bands/pixels etc) but now operating fine? Any ideas whats wrong with my iMac and what the solution may be? Also gets very hot from time to time, particularly if I'm playing music/watching youtube/movies for extended periods.

X220 Screen Blanking out

Hi,
I have a problem on my X220 where the screen blanks out.
Here's how it happens.
First, the system hangs, noticably (like freezes for about half a second)
Then the screen goes completely black
And then comes back on
None of my programs are closed or reset (Chrome, Gtalk etc.) and only thing that seems to be different is that the Lenovo Power Manager/Wireless Manager Icons seem to have reset.
Anybody know what could be causing this?
(if it matters, I have my pagefile disabled, but have 8GB of ram installed. I closely monitor my ram usage and it has never been above 4.2 GB)

AT: tocirahl
I had the same issue you describe. After booting into WIndows the system blanks a few times and eventually hangs. Sometimes I can just see a popup appearing showing "Display driver has stopped responding and has recovered".
The strange thing is that my system has this issue ever since I got yhe machine and first powered it on. Even completion of the factory windows installation was not possible due to this crash. I found out that when the Graphics Driver was installed the system would crash.
I have send it back for repair yesterday and I am still waiting to hear the cause of this blanking/crashing issue. Quite anoying because the system is not usable at all.
Any suggestions what this issue can be?!

Screen Saver when calling and need to use the Keypad, the screen saver doesn't detect the phone has left the ear and blanks out the screen. Even ending a call is difficult as the screen blanks out within seconds

I have to use the Keypad a lot when making calls. Make the call, the Robot then asks to enter a number for a service, pull the phone down from the ear, the screen may light up for a second, but then the screen saver cuts in, blanking the screen out. Sometimes you hit the Home Key to awaken the sccreen, enter your number and then back to the ear to hear the next set of instructions. Back and forth just trying to enter the options is a pain. Sometimes even trying to end the call, the screen blanks out and you fight to try and end a call.
If I use the Speaker function the keypad works; the speakler phone is not alway appropriate.
It appears that the phone gyro, doesn't detect the phone has moved from the ear to the viewing angle. This wasn't an issue until recently and I can't remeber if it's the iPhone 5 or one of the updates. It definitly wasn't there earlier on, as I threw away an Windows 6.5 phone for the same problem.
I'm not sure if it's a hardware or software (design) issue.

It is not the gyro. This has everything to do with the iPhone's prioximity sensor.
Are you using a case that may be blocking or partially blocking the proximity sensor? If you are using the case, remove the case prior to the next call to see if the same occurs without the case.

Screen blanks out when trying to move apps in itunes 11.1

I can't move apps from one screen.folder to another without the screen blanking out in itunes 11.1

I've had a similiar problem. I once tried connecting my player to a stereo system using someone elses stereo and audio cables. I connected the cables to the headphone jack and watched as my creative zvm sort of freaked out and went to the fm radio screen. However, a few seconds ago I tried this once again using my own cables (exact same type as my friends audio cables, just a different brand) and was able to successfully connect my player to my stereo reciever and nothing went wrong. So the only differences between these two attempts were the cables (which as far as I know are the exact same thing, just with some minor cosmetic differences, both had a standard audio jack that fit the headphone connection, and both split into two auxiliary connectors for audio, one red, one white), both went through different stere recievers, and I had upgraded my firmware since that last attempt.
When I first tried it and the player freaked out I wondered if it was caused by some complication due to the feature that allows you to have a wired remote control. But since it works on my setup I'm not too sure about that unless that was somethign that got fixed with the latest firmwware release.
And this is something I tried while writing this. I went into settings, went to audio/video settings and turned oof the Video Out option. Connected my usb dongle (that came with my player) to my player and connected my video cables to the player and connected the white and red connectors to my reciever. The screen stayed on and audio played through my stereo. Even with Video Out on music still played but obviously the screen turned off as it switched to A/V Out mode.
