I’m running a Dell Dimension 8400 sp2 During boot-up there is a system battery low voltage warning. I assume that means the battery is ready to be replaced. What are the basic dos and don’ts on replacing it? Where is it located and where do you buy one? Do I lose any settings when replacing it? This is the first time I have run into this. There are no other problems with the computer; it is in good running condition.
