HP Z800 RTC stops when powered off [SOLVED]
« on: August 26, 2019, 11:29:09 am »
Start with the system running, and the clock set correctly.   Shutdown/Power off.  Come back later Power on and boot up.  Clock shows same time as when I shut down!!!   :-//

Yes, I have replaced the CR2032 backup battery (the old one measured at 1.66V).

Has anyone seen this before?

I can't see any BIOS setting that would obviously cause this problem.

Suggestions most welcome!!!   I'm about to remove the CR2032 and let it sit for a while.

Thanks
David

Ah well, all's well that ends well!  Unplug, remove CMOS battery, press clear CMOS switch, replace battery, plug in again and set up BIOS from defaults seems to have fixed the problem!
