Power supply switching of a computer system by a remote controller

A computer system including a wireless remote receiver adapted to communicate with a remote controller, the computer including a power supply system selectively generating a main power supply and a standby power supply, each button of the remote controller, when activated, generating a data code at f1 frequency, the remote controller transmitting the data code out wirelessly via a carrier signal of f2 frequency, f2 being larger than f1, the computer system comprising:

• a central processor unit;
• a memory coupled to the central processor unit, the memory storing a procedure when assigns one selected button on the remote controller to be a wake-up operation of the computer system by sampling data at f3 frequency such that a code corresponding to the selected button is obtained while the selected button is activated, wherein f3 is larger than f2, and storing the code into a register within the controller;
• and
• a controller, responsive to activation of the selected button, for instructing the power supply system to turn on the main power supply to power the computer system.

A method for waking up a computer system by a button of a remote controller, the computer system including a wireless signal receiver and a power supply system selectively generating a main power supply and a standby power supply, the remote controller generating a data code corresponding to the activated button at f1 frequency wirelessly, the method comprising the steps of:

• (1) assigning the button to be a wake-up operation of the computer system, said step of assigning comprises the steps of:
• (11) specifying the wake-up operation,
• (12) instructing the computer system to sample data at f2 frequency, wherein f2 is larger than f1,
• (13) the computer system obtaining a code corresponding to the button while the button is activated, and
• (14) storing the code into a register within the computer system;
• (2) determining if the button is activated;
• and
• (3) if the button is activated in step (2), instructing the power supply system to turn on the main power supply to power the computer system.
