Bios question

[Liquid_Scope_99]

Hello lall it seems when i restart my pc after its been off awhile its like it resets the bios to default.
if i go in and reset everything and then reboot its fine but if i leave it off a while and come back and turn it on it has reset to default again .
I was thinking it was probably the cmos battery does that sound right to you guys it will be this coming weekend before i can get one .
Just wondering what you all think thanks in advace .

I would say it's the battery. Does the computer have any power running to it when it's off, or do you cut it off?

[Liquid_Scope_99]

no it has no power whatsoever running to it when its off thanks for the help

If you don't cut the power off, that will be a temporary fix. It would probably be best, though, to replace the battery.

Agreed, definately sounds like a bad battery.

If it's the same size and voltage, it should work. I think they are all 1.4V.

I believe mine is a CR2032.

Many are 3V

If you have to reset your clock (in bios or windows). as well as you bios settings, then I would agree with everyone. It should be the battery. It doesn't matter if the power is completely cut off or not. If the battery is good you should be able to unplug the PSU power cord and not loose bios or clock setting.

But if it's left plugged in with a bad battery, it will usually hold the time and settings, if you need it to.

True, if it is loosing settings while still plugged into a live power outlet, there could actually be several thing wrong. Your PSU could be going out. PSU's still supply power to the mobo even if the computer is shut off. This is for the porpose of retaining bios settings. You can get a PUS tested for about $10 and check it out. Also check you mobo's website and see if there is bios update available.

i would go for CMOS battery, take it to a watch shop, they should have one, there normally button batterys and voltage can vary, some are 1.4 and some 3v

Bad batteries can cause a lot of problems even if you have your computer plugged in all the time.
