K7S5A CMOS checksum errors

Hi,

I had this problem occur twice today during startup. It's the first time this has happened in about 5 months, when I replaced the stock mobo battery. I checked MBM5 and it's showing 3.28V for the battery, is this normal? I've also flashed the BIOS twice since I've owned it, but no other visible problems. Thx

this has happened to me before. i just went to bios, checked to make sure everything was same, rebooted, and was fine.

It usually works fine but it started acting up today. After I go into the BIOS and re-set the settings it will boot up OK. But doing it every time is a pain in the ass.

Does anyone know about rechargeable CMOS batteries? I remember reading somewhere that the mobo will charge the battery while the power supply is on, but the battery I bought was an Energizer and it didn't mention being rechargeable on the package. Thx
