Windows 10: Black screen after sleep mode

Hello.


I updated windows last Saturday 19th September 2020 and after leaving it in sleep mode it doesn't work anymore. The computer is running, but the screen is black. I have already tried to press ctrl+shift+windows+B, but it doesn't work. When I force it to shut down by pressing the power button and something weird happens: if I'm not charging the laptop, it shuts down but as soon as I turn it on again, it only shows the black screen and the computer is on; if being off I start charging it, it automatically turns on with the black screen. It seems that if it is charching I'm unable to force it to shut down. I have also tried to run it with another os in an USB stick and still it doesn't work.


I have read that this is due to the las update in September. In some places it is suggested to use ctrl+shift+windows+B, but it doesn't work for me. They also suggest changing some settings in the computer, but I am not able to even access any settings because the laptop is still in the "running mode" with black screen.


Is there any solution for this? Any suggestions?


Thank you.

sleep mode

Hi disgruntledWC,

There could be other settings on your computer that triggers your computer to go on sleep even though the sleep settings is set to never. To ensure that the sleep and display settings are properly set, I suggest that you look into the Advanced Power Settings.
Follow these steps:

• Open Control Panel and click Power Options.
• On your preferred plan, click Change plan settings.
• Click advanced power settings.
• Expand Sleep option, and make sure to set the following:

Sleep after : Never

Hibernate after : Never

5. Click Apply, then OK.

Please check also the screen saver option.

• Navigate to Settings > Personalization > Lock screen.
• Click Screen saver settings.
• Set your Screen saver to None.
• Click Apply, then OK.

Once done, please observe if your computer still goes to sleep mode after a few minutes of inactivity.

Looking forward to your reply.

Regards.

 

Laptop Screen Stays Black after Sleep Mode

Hi Danielle,

Improper power plan settings or a possible fault on the display driver after the recent update can cause your screen to stay black when waking from sleep mode. As an initial step to prevent this from happening, we suggest that you restore the power plan
settings to default. To do this, follow these steps:

• Type Command Prompt in the search box. From the search result, right-click on
  Command Prompt and select Run as administrator.
• Copy and paste or type in the command below:
  
  powercfg -restoredefaultschemes
• Press Enter and wait for the command to finish.
  
  Note: This option will delete all custom power plans and restore the built in power plan settings of your device.

In the event that you encounter the same issue after restoring the power plan settings, ensure that your device display driver is updated. You can follow the steps provided on this

link on how to update your drivers and check if the issue persists.

We'll appreciate if you can send us an update.
