Unplugging PSU wipes CMOS?

This is a problem that my rig has had forever, but after my Vista BSOD troubles, I'm looking at everything more closely to see if I could have some defective hardware somewhere...

Basically, it seems that if I turn off/unplug the PSU (Seasonic S12 - 500W), then when I plug it back in and boot it up, the BIOS reports a CMOS checksum error and all the settings are gone.

Board is Asus P5W DH. Any ideas? Bad battery? Short somewhere? Fried board?
 
So... the board could have come from the factory with a dead battery? So much for quality control...

I'll probably grab a battery and try that at some point - I'm not in a huge hurry, given I almost never turn the box off, but... if it's indicative of a bigger problem, I want to find that bigger problem.
 
a lot of these core2 boards, p965 chipset seem to have this cold boot issue.

i doubt a battery change will do anything for you if it is one of those boards.

what mobo do you have?
