Hello,
I have a pc that won't boot. It says CMOS battery low. I read somewhere that if you clear the CMOS, somehow the battery will no longer be low (I guess it's magic). I moved the jumpers to clear CMOS. When I boot with the jumpers in the Clear position, it still says CMOS battery low but it also says Checksum error. When I put the jumper back in the normal position, it still says CMOS battery low. Was I suppose to do something in CMOS setup with the jumpers in the clear position? Is there anything else I can try?

HELP!!!!

If it is one of the little round shiny ones just change the battery I think the number on it is 2032 or something like that.

If it is the round barrel type soldered on that's another story.

And welcome to sysopt.

I believe its the barrel. I don't know exactly where as I looked up the motherboard and the manual is in German. I don't see the round shiny one anywhere on the motherboard. I believe it looks like a watch battery so I'm inclined to believ its a barrel.

What can I do in this case?

The round shinny battery (watch type) needs to be replaced,then you wont have the error.I replaced one on my son's pc today(cr2032 from radio shack) Took all of 2 min.If you get a checksum error after replacing battery,just go into bios(tweak setting if you want) ...save settings and reboot.If you dont have a watchlike battery on the mobo(motherboard) then you have a older soldered on battery(looks like a big chip sometimes) then your only choices are replacing the motherboard or "wiring" a battery to the mobo.
hope this helps

Unfortunately it doesnt have the round battery. How can I wire a battery to the motherboard? I'd rather not replace it if I don't have to.

A little more info would be a great help now.

Brand of machine or motherboard.

Model number and anything else you can come up with will be helpful.

It's AMI M560. I think ver3.1.

When you first turn on the computer hit pause when the first screen appears.

On the bottom of the screen there will be a string of numbers.

Example.

2A59I-XXXX-XXXX

or

51_0102-XXXX

or

40-01S5-XXXX

Write this whole line down and post it here and we'll try to find it for you.
