Beware the Lenovo Vantage app. My PC (Carbon X1 gen 6) started to auto wake up every weekday morning at 05:30 from hibernate, even when I was away on holiday. I had a frustrating time trawling through scheduled tasks, power plan settings and device power settings, all to no avail. The powercfg sleep study and wake timer diagnostics did not help either - it just said unknown wake reason.
The culprit? It's Lenovo's own app - Lenovo Vantage. There is a (new?) feature called Smart Standby that automatically set itself to ON. This automatically wakes your computer every weekday at 05:30 ready for work. It must save all of 10 seconds start up on my laptop.
I've turned it off and hurrah, the PC stays hibernated.
Also it fixes another issue - I found that the "Hibernate After" time setting was being changed from my value. Yes, Lenovo Vantage was silently zapping that too.
So beware this dangerous app. Shame on Lenovo for turning this feature on by default and not explaining its consequences better.
