Windows 10: Windows 11 can't wake PC after sleeping for a longer period.

Computer goes to sleep just fine but does not wake if it has been in sleep mode for a longer period of time 8 hours for instance. When the computer is sleeping my keyboard's lights are turned off as it should be, and when trying to wake it the lights come on but screens stay dead. So it seems like it is trying to wake up but can't and I need to shut the computer off and turn it back on for it to work. Any idea why this could be?Specsrocessor IntelR CoreTM i7-9700K CPU @ 3.60GHz 3.60 GHz Installed RAM 32,0 GB Motherboard AsRock Z390 Extreme4GPU Nvidia 3090 RTX

Blue screen error when computer wakes up from sleep after a longer period

Hello,

I have been experiencing a blue screen error whenever my laptop wakes up from sleep after an extended period. It does not happen if I open the lid and wake up immediately, but will if I leave it longer (?hours). It will restart and seems to be running fine after until the next time I wake up from sleep. I have a Lenovo Thinkpad X1, windows 11. Please advise.

Thank you!

 

Troubleshooting PCs spontaneously waking from sleep

I've also battled with sleep/wake issues over the years, and from experience have learned that trying to find, or rationalise, the root cause is a waste of time. All you need is `powercfg`.

`powercfg -devicequery wake_armed` from an Administrator PowerShell window/Command Prompt will give you a list of all devices that can possibly wake the PC. This command is interesting because very often, it will show devices that you'd never expect being able to wake your computer. I think in one instance I had the chipset device listed!

`powercfg -devicedisablewake "device_name_from_device_query"`will prevent said device from ever waking the computer. This command is 100% the only thing I have found that will resolve sleep/wake problems. Updating drivers, unplugging peripherals, switching to a cleaner power supply (UPS), changing ethernet cables... none of those have helped, yet`powercfg -devicedisablewake` has done the trick.

Note that occasionally, devices you have disabled wake for may start waking up the PC again - this happens if you plug a USB device into a different port, or occasionally when drivers are updated, because Windows sees it as a new device. In that case rerun `powercfg` to find and disable that device again.

If this does not resolve your wake issues, I would start looking at power fluctuations.
