Greetings,
My EliteBook 745 G5, which is running Windows 10 Pro 64-bit, will randomly restart (with no error message) shortly after login with a firmware newer than Q81 Ver. 01.07.00 - 04/15/2019. If the restart doesn't occur, the system will remain stable until I lock/unlock the screen again.
I could not find any relevant entries in Event Viewer to explain this (albeit, I'm no Windows expert). The extended HP Hardware diagnostics completed without finding any issues. I reset the BIOS settings to factory defaults, re-imaged the system to a clean state with the latest Windows 10 v1909 media tool from Microsoft, applied all updates/drivers that Windows Update suggested, and installed the HP Hotkey Support and System Default Settings for Windows 10 packages, but behavior continued. Once I rollback to the 01.07.00 BIOS / firmware, the problems disappeared (seemed to occur more often with 01.08.00 than 01.09.01). I'd prefer to run the latest firmware to get other bug fixes / security updates, but I can't sacrifice stability. Any thoughts on troubleshooting further or anyone else experience this?
