Need CMOS battery help

I don't want to go to the trouble of opening up my Desktop PC. I have this HP a300n pc that cannot keep the the time current,.

When I turned off the computer and turned it back on it boots up with  Jan 2001 and a different time. I was told

that the cmos battery may be too weak and should be replaced. So, I called the HP tech help and to my surprise the tech guy

whom I talked to didn't know that the pc had a clock on the motherboard!!!! Amazing.

I need to know if anyone out there happens to know which battery model the a300n would accept. I checked the HP site and other internet

sites without any luck.

Re: Need CMOS battery help

You can purchase the battery almost anywhere. You need the CR2032 model/battery number.

Your motherboard specification:


Almost all ATX motherboards use CR2032, but the battery is very easy to remove. Turn off the PC, move it away from a carpeted area and ground yoursef (touch the faucet in a sink), remove the side panel, take the battery out, look at it, take it to your local department store watch or electronics department and buy a new one.
