What motherboard revision do you have?
Because if you have a rev.B mobo, you should
use a rechargeable battery. But if you have
a rev.D, then you have to use a non-rechargeable
battery because the rev.D mobo doesn't recharge
any battery...
My A4000D has rev.D and I've placed a coin-cell
battery in it that lasts for about 2-3 years.
I've also placed an 2x aa battery holder on the
back of the A4000 in case the internal coin-cell
battery gets empty, and I don't wanna open the
case. Very handy!
