Battery is failing. Trivial to replace (at least, it used to be, back when I had desktop CPUs).

Thanks for giving nice suggestion .

As always, be careful about ESD (electro-static discharge) when working inside your PC (touch something metal that's grounded, like a radiator or sink water tap spigot, or 'go pro' and use a ground strap on your wrist).

I've never done that!

Which (between using a ground strap, and doing a CMOS battery change) haven't you done? Do you at least ground out before touching a chip or circuit board that was shipped in an anti-static bag?

Changing the battery. I guess I touch the case inadvertently for grounding.
