So my boss brought his laptop in to me because everytime he unplugged the AC power, it shut off. At first I thought battery, being the most obvious thing, was the culprit. I found out that he had just put a new battery into the laptop about 9mo. ago (because it was losing charge after only an hour or so.
He had a virus about a month ago, and did a system restore; only AFTER this did his problems start. I tried a BIOS update, wondering if something happened during the restore, but it doesn't appear to make a difference. I have also uninstalled and reinstalled the battery controller in the hardware manager.
His battery monitor doesn't even show a battery when you go to check the charge level, and the charge light (lightening bolt) doesn't stay on when plugged in...only for a few moments after startup (or randomly).
Is this another battery problem (system does run w/o battery on ac only), or an internal problem with the mother board (charging system?).
