Abstract

A method for remote control of a computer system is disclosed. By pressing buttons of a remote controller, a computer system in remote end is operated. When users in remote end press buttons for transmitting signals, a receiving unit of the computer system receives the signals. Then the receiving unit sends a first signal to a chip unit for transmitting a second signal to a central processing unit so as to make the central processing unit stop current work temporarily and run a service program for initiating a multimedia player system mode or other modes.
