I'm working on an Acer B116 notebook that if it sits for awhile keeps losing the BIOS settings. It reverts back to UEFI, refuses to boot and the time goes back to 1/1/2014. Going into the BIOS and changing it to legacy boots it right up. I checked the CMOS battery and it's at 2.63v. but the label on it says 3.0v. Could this be my problem?
