And when I turn on my laptop it gives me the "AC Adapter - Alert - "AC power adapter wattage and type cannot be determined" error. According to the tests, battery life is excellent. Using original charger. Please help!
The battery won't charge with an unknown AC adapter. First thing to try - a new OEM Dell AC adapter. If it's not recognized, replace the DC jack. And if that doesn't do it, replace the mainboard.
