Hello all,
I just salvaged a good working Abit BH6 from a local recycling store, and it comes with a PIII-433MMX CPU.
I immediately replaced its CMOS battery with a brand new CR2033, but every time the system is turned off (and the power is unplugged) it looses the CMOS settings and I have to modify all the settings, and as you know, it becomes annoying real quick.

I have even taped the CMOS battery securely with a piece of electrical tape thinking it might be loose (it is a bit wobbly), but it did not make it difference.

Any help would be appreciated!

Thanks!

I have this issue with a core 2 duo computer. My best bet is that something on the motherboard died and needs to be fixed

I see, well the system seems to be working great, and I guess I can live with it: as long as it is still plugged-in (but powered off) it can retain the CMOS data.

You're absolutely certain the clear CMOS jumper isn't set to clear CMOS data? It's the one called CCMOS1, right above the upper ISA slot. It should be set to bridge pins 1 and 2.

If the CMOS clear jumper is not set, you can trace the battery using a multimeter. Try to see where the 3V from the coin cell goes on the disconnected, powered down motherboard.

CR2033? I think it's supposed to be a CR2032. Does that matter? Is there even such a thing as a CR2033 or is that a typo?

Typo. And it wouldn't matter as long as the battery was connected properly.

A Cr2032 is a lithium battery with 3V. It is 20 mm in diameter, and 3.2 mm thick.

So a CR2033 if it existed would just be a tad thicker. 😀

Just a week ago I've fixed motherboard (GA-586SG) with exactly the same symptoms. CMOS didn't hold data after switch off, moreover new CR2032 lasts few days. Obviously - short circuit. It was SMD capacitor near the southbridge.

Wow, thanks for your input, I really appreciate it all, and YES it was a typo!
