HP Recommended
Product: HP All-in-One 22-c0063W
Operating System: Microsoft Windows 10 (64-bit)

This HP All-in-One is only a couple of months old. Brand new, just out of the box it displayed the CMOS checksum is invalid. CMOS Reset (502) error message, but then restarted and seemed to operate normally, unless it lost all power. (Shutting down PC with power supply still hooked up did not allow error to pop up.) I also recently was having problems with the PC unable to wake from sleep mode, but yesterday I downloaded a new HP Support upgrade, and used it to reset bios to default and PC now wakes from sleep mode OK.

But I still get the CMOS checksum error from a cold start (after PC has had power removed completely). I can read the BIOS version/date, but how do I know if it is correct? Instant Chat is wanting me to send PC in for repair, but I would rather fix it myself, if possible.

Thanks!
