Title: GA-P35-DS3 CMOS checksum errors and time resets after mains power removed
Post by: Susan on September 28, 2010, 09:15:26 am

I have replaced the battery on the board, but still the bios acts as if the battery is low. If I keep it plugged in at the wall while its off it remembers the time and settings and boots fine. Unplugged for just a few minutes and it says CMOS checksum errors, so i have to load defaults and set the time and then F10 save it and then boot. Its a version 1 board with F14 bios. Has worked great for about 2 yrs. Any help welcome, or can i return it for repair out of warranty. Thanks.

Hello Susan and welcome to the forum.
From what you have explained I would say that the fault is on the board itself. The only other reason would be the battery that you exchanged is faulty. I would try another battery preferably from another source and if it still won't work properly arrange to RMA the board. ;)

Thanks Dark Mantis, I will try another battery then see about RMA. What do i need to do to RMA it as i have never done that before, how much in total will it cost. Thank you for your help.

The proceedure is simple enough. Just contact the returns department
returns@gbt-tech.co.uk
and they will email you the necessary form.
Cost wise it should be just the charge for sending the board to Gigabyte UK as now they pay for the return cost. ;)

It is still within warranty as Gigabyte guarrantee thier products for three years. So you shouldn't have any problem. ;)
