Hi, we had also trouble with an empty battery at the T112. I figured out there is a Fujitsu D2963-S11 G2 mainboard inside (Fujitsu SBC – 004-111 – AE8214 also called) and I had to boot it after Battery replacement using the frontpanel connector. But BIOS is on default setting, means display only VGA Port and Boot from Network. Wanted to Change but BIOS asking for a password. We dont have one. Anyone an Idea how to reset it or is there a service password known who is also given on delivery ?
