CMOS Checksum Error - Defaults Loaded

Had this happen on booting up this morning.

Pressed F1 and the clock had reset to January 2004. Reset the time and date then rebooted, all was OK.

For sometime now if the weather is cold, the clock has lost time.

I presume that the MOB battery is to blame. The board is a Gigabyte GA-7DXR.

Have looked in the manual but it does state the battery specification.

Is this a serious problem i.e. the BIOS could revert to the defaults ?

Probably the best thing is to just replace the battery. They cost just a couple of pounds. Maplins and the like will sell them.

Your battery is located to the left of the 3 white tagged memory slots. click here

the bios can some times reset it's self if

new hardware is added

windows shut down after a serious error

a glitch with memory.

most of the time, its the battery.

I will close this post now as the fault has rectified itself.

Many thanks for the replies.
