How come my laptop will not boot up if I remove the battery?

by on November 5, 2011

Q: I have a Dell Latitude D510 which was dropped. The computer still works, but only as long as the battery is charged. The AC adapter does not recharge the battery. The battery was tested and the AC adapter was tested, both tested OK. If I leave the battery in the laptop will boot up. But if I remove the battery the unit will not boot up. Anyone know how to fix my problem. Thanks
