Problem encountered on multiple Yoga 370 : unattended Hibernate
(https://download.lenovo.com/supportdata/driver.html?id=DS032258&l=en) --> PM already up to date
no specific keyboard entry , no keyboards shortcuts (it happens twice while skype meeting f.e.)
not related to a time-out power save mode or whatever (High-Perf power scheme, no sleep no hibernate when plugged-in)
Lenovo Companion not installed
Check Event viewer logs : Power button or Lid Switch ?!?
Log Name: System
Source: Microsoft-Windows-Kernel-Power
Date: 04/04/2018 10:22:58
The system is entering sleep.
Sleep Reason: Button or Lid
