How do you check whether the CR2032 is supplying electricity to the CMOS
after the PC is shutdown?

1. Enter a non-default BIOS setting via the BIOS menu.
2. Key F10 to save BIOS settings and boot.
3. Shut down.
4. Restart and inspect BIOS settings: if your entry in
#1 appears, the battery is supplying enough power.

I actually unplug the PC and waited an hour. Nothing went wrong.

I needed to wait till tomorrow for a longer test period.

I hope nobody in my sister's home actually altered the settings to
justify the purchase of a new PC.

I replaced the power supply of that PC last night (Antec EA-380). This
morning, no problem reported. Need to wait a few more nights to be sure
whether it's the source of the problem.
