Product: HP All-in-One PC 24-df1000i (30J69AV)
Operating System: Microsoft Windows 11

When I turn on my PC , message is being displayed " The CMOS checksum is invalid, CMOS report (502) " and ask for restart. But after restart the same message is again appearing in the screen. How to solve it?

When powering on, press the ESC or F10 key and go into the bios setup and change something.  Add a second or two to the time.   Then save and exit.

If it happens again you should swap out the CMOS battery.  I assume you are not dual booting another operating system such as Linux and then going back to Windows.
