[G4] OT, Dead APC backup

[k s d]

Wow! I was away for a couple of days.
Thanks for everyone who replied. I enjoy taking electronics apart to see how 
they work and I was hesitant to do this w/the BU because I wasn't sure 
whether it retained a charge or not (Like monitors that can hold a charge 
for a very long time)... I'll open it up and see if a new battery will help. 
Thanks everyone.
