Unlocking your Toshiba Satellite BIOS isn't the same as loading any piece of software on your computer. The BIOS is the gateway to your entire machine--it controls the way your Toshiba Satellite laptop computer operates. Because of this, the only time you can actually unlock your BIOS is when your computer is starting up. This will require a restart or turning your computer on, depending on the state that it is currently in.
Press "Power" to turn on your Toshiba Satellite. If the laptop computer was already on, restart it.
Hold the "ESC" key until you hear your computer beep.
Tap the "F1" key to unlock your Toshiba laptop computer's BIOS.
