Help! I keep losing CMOS settings, even with a new battery.

Gigabyte GA-7ZXR
1.33 GHz T-bird
768 MB PC-133 SD-RAM
Win98 SE
BIOS ver. F9

For the last few days, when I turn on my trusty machine, it comes up beeping in need having the CMOS reset. I can turn if off for a few hours, come back and turn it on, again, and it's fine, but every morning for the last few days, it wakes up with BIOS Alzheimers.

So far, I have replaced the battery (which measures good with a volt meter) and reflashed the BIOS with the same version I have been running.

The only other thing I can think of is that the CMOS EPROM is going bad. Any other ideas?

TIA

Sounds like a bogus board. I'd email giga-byte and get a replacement.

I had the same thing happen years ago on an Abit BX2 mobo. I replaced the EPROM chip with a new one from Abit. It cost about $30 because the board was out of warranty, but it fixed the problem.

Hi,

One last thing to try - Check that the battery contacts are clean. If possible, use a multimeter against the contacts (with battery in place) to measure the potential.

Good luck,

Andy

Thanks for the input. It happened again, this morning.

I'm going to try to find a replacement EPROM chip, locally. If I can't, I hope it isn't too expensive wherever I find one. Right now, I'm beginning to think somebody sneaked into my case and replaced it with RAF (Random Access Forgettory). :Q
