Satellite L855-149 screen is black while waking up from sleep mode

Hi all

I've had this laptop for about a month now.
I'm having a problem with the screen, when the computer is left idle, the screen turns off or the laptop goes to sleep (as expected) but when I go back to the laptop and press a few keys or move the mouse from the laptop back to the top but the screen remains black.

I'll have to do a hard reboot of the machine for me to be able to reuse it, which as you understand it is not ideal.

Thank in advance for any help.

Is that what happens since the first day of purchase?
I mean it would be interesting to know if this problem could be reproduced right after that the laptop was recovered using Toshiba Recovery option.

According to my experience such issue could be related to the problem of software (background process) or problem of graphics card driver or BIOS.

  • y510p screen stays black after waking up from standby or hibernation

    Seems that since the latest graphics drivers NVIDIA update (I'm not 100% sure on this subject, but I think that this is the case), my screen remains black at being woken up from sleep or hibernation. I know it's on, and what is not a matter of the computer is slow, because it is not and even if it were, leaving for several minutes and it remains empty and the power button and keyboard and everything comes on and it starts to heat up to the top, so I know it's something. Hit the FN - F2 for the backlight does nothing, so I don't think that is the question. The only way to solve it is to hold down the power button / stop and reboot, which pisses me off because sometimes I have a large upward job and am forced to lose. Anyone else see this problem? Could it be related to new graphics drivers, or is this something worse and related material? My screen looks OK when it comes to everything else.

    Thank you!

    Well everyone, I think I 'solved' the problem. The latest NVIDIA drivers, I have installed the other day fixes the problem. I can sleep, hibernate, shut down, you call it without going through the screen lights up only not for the last day today. I can't say for sure, but I am sure that it was the matter of 99%. I appreciate the help nonetheless.

  • Alienware R5 is not Waking Up from Sleep Mode

    Hi all. I recently bought an alienware aurora r5, and it works fine except he wakes up not of mode before pressing the mouse or the keyboard. I have an Acer H236HLBID monitor connected to the GPU via HDMI. The monitor will turn on (No Signal screen) when I move the mouse, but the computer itself doesn't go out of fashion 'sleep'.

    I tried upgrading the BIOS to the latest version, but it does not solve the issue. I also tried to reinstall the drivers of ASMedia USB 3.1, of https://www.reddit.com/r/Alienware/comments/4ckz82/x51r3_wont_wake_up_and_freezes_randomly/d4za4ma?st=isy4l18r&sh=69044241, without a bit of luck.

    Here is some information on my system:

    CPU: Intel Core i7 6700 k

    GPU: GTX 1070

    Any help would be greatly appreciated. Thanks in advance!

    I found the cause of the computer do not wake mode "sleep" using USB devices. You need to boot into the BIOS setting and activate "Allow the devices to wake mode ' sleep'" or something similar. By default, this option is disabled.

  • Computer is unresponsive after waking it from sleep mode

    This is starting to happen more frequently.

    I put my computer to sleep and 5 minutes in forest exploitation and using anything (e.g., google chrome or itunes), the application crashes.  I then click on Ctrl-alt-del, but never, it appears (usually works).  Then I move the taskbar, and it shows a "explorer.exe is not responding...". ».  Then the entire computer just freezes, and then the only thing I can do is hold down the power button to force a stop.

    My wife's computer is also windows 7, and it still works ("not responding") when she wakes up from his sleep.  If its something with my computer.

    Is there any solution for this?

    Hi XxRicyxX,

    (1) remember you to make changes to the computer before this problem?

    Step 1: Disconnect all external devices (printers, scanner, USB (universal serial bus) drives, etc...)  Except the mouse and keyboard, and then test to see if the problem persists

    If this solves the problem, then add back devices at a time until you discover the piece of hardware causing the issue.  Then get any drivers\software update for the device.

    Step 2: Run the troubleshooter to power and check to see if that corrects this problem

    Open the troubleshooter of power
    http://Windows.Microsoft.com/en-us/Windows7/open-the-power-Troubleshooter

    Step 3:  Clean boot the computer, allow the computer to sleep and test

    Follow step 1 in the link below

    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7
    http://support.Microsoft.com/kb/929135

    If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem.

    Continue with the remaining steps to pin-point on the third party service.

    After find you the program that is causing the problem, you will have to perhaps to update or install a newer version of the program, if you rarely use that you should consider uninstalling the software.

    Important: Be sure to put the computer on normal startup followed step 7 in the link.

    Can someone please help?
    My Toshiba Satellite L855-149 primer not Windows or same boot a disc to install a new copy of windows 7. He keeps making a firm hard down when trying to load the screen of windows 7. It will only start in safe mode.

    Its a little strange... my head made shipwreck.
    Anyone had this same problem?
    Help, please

    As I see you have tested on power supply battery. The same thing happens on the power supply?

    Anyway, this issue is for the service then I recommend strongly to contact the nearest Toshiba service provider and ask for help. In my opinion, these questions it's that no much you can do about it.

  • Satellite a200-1sv screen remains black at startup in Vista

    Hello

    We have a problem with Toshiba Satellite A200-1sv my girlfriend: when we started, most of the time, the screen remains black, while the computer starts: after awhile, we can hear the sound of windows (vista).

    In addition, if connect us another screen of the computer, it displays the scheduled start screen. In order to use the computer, it must launch a few times... The support guy where we bought the computer told us "the computer is not compatible with Vista, we cannot do something".

    Can we do something?

    Thanks in advance,
    Ju

    I have to smile to read this message
    Mainly, this statement is funny;
    > The support guys where we bought the computer told us "the computer is not compatible with Vista, we can't do something."

    I think that this laptop has been delivered with the Vista operating system. So why the guy said that the laptop is not compatible with Vista?  :| …. that's nonsense.

    First the A200-1SV belongs to the PSAE6E series and it s fully Vista capable.
    Secondly, like you say the external screen displays home Toshiba screen and so I guess that's just a matter of adjustment.
    What you can do is to use the FN + F5 key combination to switch between display devices.

    If it doesn't help to try to put the laptop back to the factory settings using the Toshiba Recovery CD!
    In this case, the new OS, driver and tools will be installed and then everything should work fine.

    Good bye

    I Hare recently upgradedmy Toshiba Satellite L855-149 to the most recent version of windows 8 6.2 and since I did then the Synaptics touch pad stopped working, I guess because the driver does not work with this version of windows 8.

  • Satellite A100-049 screen remains empty when reactivated from sleep mode

    Intermittently, have been left for a while my screen A100-049 remains empty when reactivated from sleep mode. It does not meet the access keys and have checked the settings which seem to agree.

    Hello

    What do you with the mode 'sleep'? Do you mean the hibernation mode or the mode booth? What operating system do you use?

    Listen buddy. It's really not easy to say why it happens without running diagnostic tests. I think you should try to update the graphics driver and check if you are using the latest version of the BIOS. Two updates might be useful in resolving these issues

    Good luck

  • Satellite A500-18 x - don't wake up from sleep mode

    I've had this laptop for a little over a week and when it goes into mode 'sleep' trying to wake him up, all the lights on the keyboard lights up and I hear it works but the screen remains black. I updated display drivers and that fixed it for a few days but now it stopped working again. updated audio drivers would force it to not wake from sleep mode kos that he worked well, since I've updated the display driver and then yesterday I updated audio drivers and he returned to not wake up once again in mode 'sleep'. any help much apreciated.

    Updated the BIOS and update the driver to display again.
    Maybe the after the audio driver that something was wrong, you can clean the registry using CCleaner in most of the cases it s a good idea.

  • m8200n crashes, blue screen, freezes, power light flashes blue in Sleep Mode!

    Hello world! I have the HP m8200n and similar problems for a year now such as published by other people with the Black Out of the screens, screens blue and gel. I did a lot of game online lately and installed a video card, better food, added a GB of ram and a Blu - ray burner and also added some fans inside. I am still using the Windows Home Premium 32 bit OS that comes with it, and all the software is always up-to-date. Only thing I noticed what happens regularly is when the black screen, blue screens or freezing is usually just after I wake the computer from sleep mode. Then I usually attempt to restart it places several times until finally, it starts and works without any problem. Of course, I ran the diagnostics and all past. But just recently noticed when I put my computer into sleep mode, the front power led does not more change to amber color, it just flashes blue and turn off without reason. He always wakes normally when I move the mouse, and the blue light comes on and when I put it in mode 'sleep' it goes back to the blue flashing light. In addition, when I start to play online the rear case fan begins to spend a quick back and forth and then at normal speed. Usually, I try to blow and clean up so much dust that I can possibly do. But I wonder if these are all signs that my computer is about to fail completely? No matter how useful counsel that it would be VERY, VERY, very appreciated!  Thank you!

    I have same m8200n and same night Mare, I pulled out one of the ram sticks first the left right and fixed it

  • Satellite L750 - does not wake from sleep mode

  • Satellite U920T - the screen goes black when you drag the keyboard

    This morning, I turned on my U920T-10 days but the screen remained black.

    At first, I thought the screen was broken, but in mode 'Tablet', the screen became. Now when I slide the keyboard the screen goes black again.

    How can this problem be solved?

    Hello

    For me, it looks like a bad connection somewhere between the screen and the motherboard.
    This could be possible reason for failure to display while sliding in and out.

    I guess this can be resolved easily and I think that it is a job for a technician (authorized service provider). I recommend you contact the service technician in your country to get the laptop fixed. I hope that the warranty is still valid in order to repair for free.

    I hope that this can be corrected. I keep fingers crossed.

  • Satellite P100 - the screen goes black

    Hello

    I have a Satellite P100 and randomly, the screen goes black but the system continues to operate. I downloaded the latest drivers from toshiba, all power options the maximum support, run ccleaner and driver Sweeper to remove the old entries driver, re-installed the login screen of the mobo and nothing seems to work.

    The screen goes black sometimes when using windows but STILL turns black as soon as the ramps of gpu for example of playing a video or comparative analysis of the graphics card.

    Any help would be greatly appreciated.

    Hey,.

    > ALWAYS goes black as soon as the ramps of gpu for example of playing a video or comparative analysis of the graphics card.
    This means that the graphics card is defective

    Theoretically, it could be an overheating problem too. Higher time can also cause a black screen. You should try everything that is possible to clean your laptop using the jet of compressed air to blow the dust from the cooling fans.

    If it doesn t help it seems to be a hardware malfunction but seriously a point would be interesting: have you noticed the same thing with preinstalled OS (Vista) Toshiba?
