It's on the motherboard. Unplug the computer, remove the battery and get the numbers off it. Radio Shack or any store that typically sells watch batteries should have them. You might want to bring the battery with you to cross reference it with.
Thanks for your help.
I did changed the big battery and tried updating the time and date but was not successful in resolving the problem of time and date. There is another small battery which I cannot locate that keeps the exact time and date.
