System battery Dell Dimension E521

[rwarth]

I get "Warning BIO S V 6.00 system battery is low."
Which battery is this, where can I buy one, how do I install it?

Most desktop boards have the "button battery" a cr2032 lithium, which sells for $2-3 at many stores. To remove, use a small flathead screwdriver and press on the tab holding the battery down. Then take it with you and match it up. Even walmart or target may have this battery. Frys has it; you may also find some at goodwill stores that sell computer conponents.

Sounds right.
