Windows 10: PC won't go into sleep regularly and wake up in an hour after upgrade to OS Build 19041.388

Hi,


Windows 10 Pro, 64 bit. Recently upgraded to OS Build 19041.388


Since the upgrade, I have noticed that the PC no longer enters sleep mode as regularly as before the upgrade.


Before the upgrade, PC will enter sleep if idling for 30 min. I have noticed it will wake up around midnight by itself but will go back to sleep after a few min.


After the upgrade, I have not seen it once entering sleep mode after idling. If I make it sleep manually, it will wake up in less than one hour. Once awake, it won't go back to sleep.


How could I troubleshoot? Some information below


In the Event Viewer, the most recent wakeup is 0:36.

PC Won't go to sleep - Fixed Feature Power Button

Hi recently my laptop won't go to sleep, after one second is back from sleep saying that the power button was the trigger for waking up.




I tried everything that I saw in similar post all over the forums.

1. All the drivers updated
2. Turn of all wake timers and allow device to wake up the computer from mouse, keyboard, Realtek PCIe Controller, Wireless AC.
3. Turn "wake computer" from UpdateOrchestrator in Task Scheduler
4. Run all the troubleshooters from windows
5. Reinstalled Windows latest build
6. Tried on older Windows build

Has anyone can suggest anything else ?
It drives me crazy , its suddenly happened and now a can't find any solution

 

PC will not automatically go to sleep after upgrade


Hi all,

After upgrading to Windows 10, my PC will not go to sleep automatically nor will the displays turn off after the specified time (10 minutes). If I put it to sleep manually from the Start menu, it will go to sleep and usually stays that way until manually woken up. I had no issues with my PC going to sleep in Windows 7.

So far I've tried:

• Unchecking "Allow this device to wake the computer" on my NIC
• Disabling password required when the PC wakes up (saw it on another thread so figured I'd try it)
• Updating all drivers (chipset, graphics, etc)
• Updating my motherboard's BIOS
• Disconnecting my keyboard and mouse
• Checking powercfg /requests (its blank - everything is none)

Anyone run into this yet or have any ideas on where to go from here?

Thanks!

 

Windows 10 Upgrade 1903 64 bit Sleep Wakes Up on Multiple Computers

Someone suggested I look at all the drivers list before and after the upgrade. I did, nothing found/changed in drivers.

What I did discover was that after the KB4503327 upgrade, if I put the computer to sleep mode (via power menu,) I discovered the computer wakes up after the minutes set in the "turn off screen".
So, if the screen shutoff were five minutes and I put the computer to sleep, it would wake up after that amount of time, then turn the screens off after another time period of five minutes.

At this point, I have set the screen turn-off to "never" and any other sleep mode to "never".
Then, when I put the computer to sleep, it stays asleep.

This issue was never seen until this OS upgrade was installed in the system.

My next step is to upgrade the video adapter (something from 2007) to a new and different model adapter to see if that corrects this issue, or not. For now, my work-around is to set "never" in "sleep mode".
