Let use sample event
The system has returned from a low power state.
Sleep Time: 2020-10-09T06:47:50.010484400Z
Wake Time: 2020-10-09T07:40:18.281270500Z
Wake Source: Unknown
What can cause that MS Windows do not gather information about wake source? I guess when system is smart enought to be able to wake up by signal from some device like mouse or graphic tablet, it should be also capable of gathering information about signal source.
Why is this information not filled? Is it due cheap HW, bad settings of USB controllers, badly chosen USB ports for particular devices, UEFI settings, bad device settings, bad power management setting, …?
