Windows 10: In Windows 10 version 1809, after the system wakes from sleep, the display’s brightness...

After installing Windows 10 version 1809 and performing the initial setup in Out-of-Box Experience (OOBE), brightness worked correctly. But after waking from sleep, the display’s brightness appears to be very dim. The display is only able to reach about half of its regular brightness.

wake from sleep issue in windows 10

Hi,

Thank you for posting your reply. Apologize for the delay in response.

I suggest you to check which devices are configured to wake up the computer from sleep by following the steps below:

• Right click on Start icon and select Command Prompt (Admin).
• Type the command line below:

Powercfg /devicequery wake_armed

3. Check if the devices (Keyboard, Mouse, Ethernet cable) are listed.

If the system is not going to sleep and going to Hybernate, the only option to wake up is to press the Power button.

Hope the information is helpful.

 

1809 not waking up display from sleep sometimes


I have a machine that has developed a peculiar issue only since going to 1809: occasionally when the display (Dell UltraSharp U2713HM) goes to sleep, it won't wake no matter what I do locally or remotely (via RDP or TeamViewer). It's interesting that the most recent patch (17763.168) includes this fix:

• Addresses an issue that displays a black screen on some servers when waking a display from sleep.

But I'm still having the issue. At first I thought maybe it was the display going bad, but it's fine outside of Windows. Once it happens the only way I can get the display to come back is to power cycle the machine.

I have an Nvidia 1050 Ti card with the latest driver (417.22 from December 3rd). I checked the Nvidia site for firmware, since I know there was a DisplayPort 1.3/1.4 issue that could cause this a while back. But I ran their updater utility from June and it said I was current. I checked Dell's website for any firmware updates for the display, and there are none. The BIOS on the machine is current.

Any ideas?

Thanks
