Solved BIOS keep resetting everytime plug off

[leonnkeong]

My BIOS keep resetting after I shut down and plug out. I am suspecting CMOS battery drained out but this PC is only 3 years+. Moreover, my time and date DID NOT RESET back to the default, it still remain as usual. Any idea on this?

I'm using GIGABYTE GA-Z77P-D3.

Thanks in advance guru!

Check the CMOS jumper on your MB to see if it's still on the "reset" position.

Nope. I never open my chassis recently anyway, nothing changes in there. Any idea?

change the battery for the cmos.

But my time and date didn't go away, still CMOS battery problem?

check for a update for the bios ? sometimes weird things just happen ..

Currently the most recent is F7. I'm using F2. But weird thing is, it was okay for the last 3 years, just why suddenly pop up such thing. :shock:

I understand what you are saying about the system clock seeming to rule out the battery. However, you can't be sure which components are more or less tolerant of marginal voltages.

In troubleshooting a thing like this, I would go from "easy" to "hard," that is, first change the battery (cheap, low risk), before moving on to something like flashing the BIOS or looking for a short in the hardware.

I have a Gigabyte motherboard, and the BIOS has a way to set it to a "known safe state." You might want to do that after changing the battery.

Just to be clear though if the current BIOS is F7 (actually I think there's an F8a beta) and yours is F2 that would be on the list of thing to address. Just move it to after the easy stuff.

Right you got the point. Gonna replace CMOS and see how is it. Will update here.

Update : Changed CMOS battery and everything is fixed. Thanks!
