Warning Message

Alert! The AC power adapter wattage and type cannot be determined. The battery may not charge. The system will adjust the performance to match the power available.

This is usually due to a dusty charger and charging port or bad outlet. Clean your charger and port. If that doesn’t fix the issue, try plugging your charger into a different outlet.
