Windows 10: Seemingly random black screen after sleep and keyboard disabled

Hi,

When I send my desktop pc to sleep, it sometimes comes back, sometimes does not. When I say he doesn’t come back I mean he restarts, it just doesn’t show anything on screen: only a black screen. I can’t seem to establish a pattern of when it happens beyond that it usually happens the third or fourth time I send it to sleep (the trigger might be time of sleeping frequency). Running Windows 10 home, 1909, 18363.657.

I’ve tried this troubleshooting by now, to no avail:

1. Turn off Hibernation: “powercfg /h off” on Command Prompt (just tried, even if the pc is a desktop)
2. Turn off Fast Startup: I think I did this, though can’t seem to find the setting any more on “Power Options/Choose what the power button does/Change settings that are currently unavailable” (been fighting this problem for some weeks now). I may have dreamt I turned it off : S
3. Disable “Wake on Magic Packet” and “Wake on Pattern Match” on ‘Network and Sharing Center/Change adapter settings/Properties (of the connection without the red cross)/Configure’.
4. “Windows key + Ctrl + Shift + B”: I would swear it once worked (maybe the pc was just slow waking up). I’d gladly try it out again, if not for the keyboard being lately disabled by the event of black screen. I’ll elaborate:

I’ve usually woken up the pc by pressing a keyboard key (also in the previous W7), and so I do now. However, now, when the pc is slumbering, I wake it up pressing a key, and the black screen case happens, the keyboard doesn’t seem to work anymore: lights off, and no living signals.

Maybe it has something to do, maybe not, just to let you know: I’ve always had problems accessing BIOS through this very keyboard (the one figuring in my pc specs), as it has never (neither when running W7) seem to turn on before Windows was initiated. In those cases I just used an old keyboard which works through a PS/2 port. Yet, I can’t see why these cases should be related, as in the matter in hands Windows is already launched.

Thank you in advance

I get a seemingly random series of black bars on the screen when I connect to servers using Remote Desktop

Original Title - Remote Desktop Black Bars

Hi All -

I get a seemingly random series of black bars on the screen when I connect to servers using Remote Desktop or RDCMan. I just solved the issue in RDP by disabling persistent bitmap caching in RDP. Now I'd like to find out if/how to turn it off in Remote
Desktop Connection Manager.

Thanks,

Joey

Disabling laptop keyboard

Hi,

Thank you for posting your query in Microsoft Community.

As per the description. Let me help you in resolving the issue.

I suggest you follow the steps below and check if that helps:

• Press Windows + X and select
  Device Manager from the list.
• Find Keyboards in the list of devices and click the arrow to expand it.
  
• Right-click on the internal keyboard and click Disable. If there is no Disable option listed, click
  Uninstall.
• Click File>Exit. Your laptop’s internal keyboard should now be disabled.

Note: If you had to choose Uninstall instead of Disable in step 4, the keyboard will be automatically detected and re-installed if you ever have the Device Manager scan for new hardware for some reason. If that happens you’ll need to repeat this procedure
in order to uninstall it again.

Hope the information helps. Please let us know if the issue persist and we will be happy to assist you further.
