About 10 years ago I was a certified Compaq and Toshiba service engineer working for a repairshop. Some laptop models did have those eeprom passwords, even back then. IIRC for certain Toshiba models you needed to have a special connector, attach it to the printer port, turn the laptop on while holding F2 and the bios password would be cleared. Taking the batteries out really didn't work.Quote:

That would effectively erase it.
