How to unlock bios of toshiba portege m500
two options
1. look on the mother board for a small round battery about the size of a nickle, remove it, start pc, after start up shut down, replace battery, start up again... or remove battery, let sit for about 30min, replace battery start pc.
2. look for a small red or yellow toggle switch or button on the mother board, (should say "reset bios") push button, restart pc.
i assume this is a lap top so there will be some disassembly of the unit, not to extreme though, usualy the battery and the switch/button are next to one another and located toward the front of the mother board, and if in lap tops the battery or batteries are in a plastic covering wired to the mother board with a small connector, just unplug connector if you cant find the reset button.
hope that helps
