I just started using a Tripp Lite 300 Power Inverter and used a Dell Latitude 810 with it.
Not sure if this is coincidince or not but now the laptop wont charge with the AC Adapter anymore, even if plugged into regular AC plug at home or office. PC states it does not recognize the type of AC Adapter and will work slower and battery will not charge.
Is it possible that the Tripp Lite inverter did something to this AC Adapter?
