Title: Security control for computer power supply system

Abstract: A computer system power-on security control that does not allow a computer power source to turn on until a valid passcode is entered. The system includes a mouse intercept unit for intercepting mouse signals directed to a mouse controller in the computer system when the power source is off. A memory stores valid passcodes used to power on the computer system. A comparator unit is configured to compare received mouse signals to the stored passcodes. A power supply control unit, connected to the comparator unit, outputs a power control signal to turn on the computer system power source when the mouse signals match the stored passcode.
