I have a laptop that will not power on. Before this level of failure, I was provided the battery temporarily disabled. Rebooted the pc into BIOS. BIOS regonized the adaptar but no battery. Shut the unit down to remove and reseat the battery. Booted into BIOS, same issue.
I read a forum to hold the power button with battery and ac adapter disconnected to discharge device for 30 seconds as it was the longeat recomended. Reconnect battery and attempted to power device. Connected the ac adapter and attemped to power. No power.
