Windows 11: Randomly wakes from hibernate

Operating Systems & Open Source Windows

Hi there,

I’m always using hibernation instead of shutting down my system to easily continue my work where I left off.

This worked fine for almost 2 years until suddenly starting about 10 days ago, the system randomly wakes from hibernation on its own.

The event log is useless e.g.:

The system has returned from a low power state.

Sleep Time: ‎2025‎-‎01‎-‎08T18:41:39.755584400Z
Wake Time: ‎2025‎-‎01‎-‎08T18:43:44.071271200Z

Wake Source: Unknown

What I tried so far:

  • Reset the power plan
  • Disabled wake timers (confirmed using powercfg /waketimers)
  • Disabled “allow this device to wake the computer” for all devices
  • Did a Windows repair installation
  • Updated some drivers
  • Reset the BIOS
  • Updated BIOS to latest version
  • Disabled “wake from RTC/PCIe” in BIOS
  • Disabled “WOL” in BIOS

This automatic wake as well happens if no USB device and no network cable is connected!

Any ideas?
