My boss has a Powerbook G3 (lombard i think?) and suddenly it's taking litterally DAYS to get the battery up to half full, but it still won't boot - not even if plugged in. So, I assume the power adapter is to blame, along with the ancient battery, but when looking for deals online I keep seeing how-to's on replacing the power card? Does anyone know what the symptoms of a failed power card are? Thanks!
