I want to change the temperature at which the laptop turns off itself since it's pretty low(About an hour playing Assassin's Creed Brotherhood will get this guy hot)It didn't have a password since i had to go to the BIOS to change the main boot device to CD so i can install Windows 7(it didn't come preloaded)And after installing the fingerprint device driver(i believe it asked me to make a BIOS password that i later forgot...)It's a brand new model.I don't believe there would be a master password since by default BIOS was unlocked.
