PC shuts down when put to sleep

[1pbfoot]

I had a problem, HP ENVY 13 F.18 BIOS update results in my laptop doing a hard reboot, every time the computer goes to sleep (either via button, or by OS usage timeouts).  Trying to find info how to rollback to a previous BIOS (F.12), but the Insyde BIOS updater refuses to downgrade versions...

Hi all... I just discovered another problem with this F.18 version of the BIOS.  Specifically, a Windows 10 shut down actually results in a reboot.  Even a hard shutdown (hold power for 5 seconds) results in the computer rebooting, regardless of whether on battery power or AC.  As of now, I have no way to shut down this laptop, except by letting the battery completely die.

Please stay away from the F.18 version of the BIOS.

SOLVED...  Basically, the F.18 BIOS upgrade corrupted my CMOS settings, but not in a way that was detectable by the BIOS.  Specifically, going into the BIOS Setup & changing settings didn't resolve the problem.  Restoring the F.18 BIOS (stored on a hidden partition on the SSD HD, or via a USB flash drive) did not resolve the problem.  Attempting to revert back to the F.12 BIOS (including by trying to restore via a USB flash drive) did not resolve the problem...

The solution is to clear the CMOS using the WindowsKey + V method outlined in https://support.hp.com/us-en/document/c02693833 . (All other approaches, including WindowsKey + B failed).  You then have to change the settings in the BIOS setup as appropriate--but since there are so few settings, it's a quick endeavor...  My laptop is now fully functioning with the F.18 BIOS.
