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.



Thank you,



Don DeWitt
