My laptop keeps giving me this message at boot up "The Ac power adapter type cannot determined. Your system will operate slower and the battary will not charge. Please connect a dell 65w ac adapter or higher for best system operation" I have tried 2 chargers and am getting the same problem and when i go in to the bios i get 2 battery option
Battery info "idle 0% charged"
Battery health "not installed"
Is there anyway of finding out if the battery is at fault as I dont want to have to buy a new one only to find out there something wrong with the laptop
