Display all power related events (turn-on/-off/sleep/hibernate/...)?

Solution 1:

I think you also get what you want by running the following command (elevation required):

powercfg /sleepstudy

Sleep Study report saved to file path C:\WINDOWS\system32\sleepstudy-report.html.

The report should contain all sleep, hibernate, shutdown related events and some other related information:

Note: also you might be interested in what powercfg /systemsleepdiagnostics generates.
