[ltp] 770X Batteries

[John D'Ausilio]

Yup, that's the symptom all right. Search battery on the IBM site, follow

I believe these batteries have a small processor in them which monitors
charge going in and out, and it seems that it can get confused. Try that
procedure out and see if it works before you shell out for a new battery.
