Windows 10 Inconsistency between System Events and POWERCFG /SYSTEMSLEEPDIAGNOSTICS

Hello,


I think I see a discrepancy between events in System Event viewer and what POWERCFG /SYSTEMSLEEPDIAGNOSTICS reports.

In Event viewer I see the following sequence:

00:48:02 Kernel-Power Event ID 42 (System enters sleep)
00:48:02 Kernel-General Event ID 1 (Time sync)
00:48:02 Hyper-V-VmSwitch Event ID 24 (No longer operational)
00:48:03 Kernel-Power Event ID 107 (System resumes from sleep)

So only one second of sleep. After that, the first event is around the time I woke the system.

However, the system was asleep for the whole night, until I woke it with the power button. This is confirmed by POWERCFG /SYSTEMSLEEPDIAGNOSTICS, where can be seen that the system was asleep.

So where comes event 107 from, and what does it mean?

Event 42 is a problem in itself (for me):

- the event states that the reason for sleep is Application API. This tells me exactly nothing.

- I have tried to configure the system in such a way that it NEVER goes to sleep, unless I tell it to. I went everywhere, Settings, Control panel, Group policy (both local and domain). I let programs try to prevent sleep. Nothing works. The only consistent thing is that sleep only occurs when the lid of the laptop is closed. Not immediately, but after a random time.

Hardware: Asus N53SV, 20 GB memory

Software: Windows 10 Pro build 14393.693. Reinstalling Windows from the ISO downloaded from Microsoft did not help.


Any comments?

TIA,


Bart
