CMOS Battery low / US486 P3 Main Board

December 29, 2009 at 10:12:33
Specs: Windows 95
When booting, comp gives the message: "CMOS battery low, press F1 to run SETUP". Could you please tell where the battery is located and what type it is? The computer was not powered for almost 1 year.

Thanks guys, the first problem to solve is to find the battery on the motherboard, which is a US486 P3 motherboard. I opened the comp. and I just cannot see anything looking like a battery. Does anybody have a diagram of this motherboard and the battery type?
Thanks

Jennifer, this is a desktop, 15 years old, put together by a small company named GB486 Computer systems, and this company no longer exists.

The problem here is that the US486 kind of indicates the board ran 486 processors yet you indicate P3 processor. There are a couple of earlier pentium versions in between.

Where did you pickup that model number?

That's what the book of the motherboard says: US486 P3 Main Board. It came with the motherboard and gives all info about it but location of the battery. There is only one spot on the diagram, which says "J2 external battery connector", and it's shown as a small rectangle with the numbers 1 2 3 4 in line and in the rectangle. I'm not sure whether this is the CMOS battery. The general specs of the motherboard say that there is a rechargeable battery and external battery connector on board. This computer was built by Gainberry Computers, a company that no longer exists.
Ask me for more details if you want, maybe I can find them in the book.

That's an old 486 motherboard. The P3 is part of the model number and not a cpu designation:

Likely the battery is one of the barrel-shaped 3.6 v rechargeable ones, usually located near the keyboard socket. They tend to leak and corrode after a few years so if you locate something that shape that's nasty looking, that's probably it.

The link above shows an external battery connection. They all had those connections but usually came with a rechargeable battery.

A Batteries Plus store will have replacements or Radio Shack or a computer supply store.

The one I'm thinking about looks like this:

If that's the one and you replace it, make sure you get the polarity right.
