• operating one of said plurality of remote controllers to turn on and boot said computer;
• waiting a predetermined period of time for said computer to lapse into a stand-by mode;
• pushing a button on one of said plurality of remote controllers to attempt to bring said computer to a normal mode;
• transmitting a password to said computer from said remote control device that attempted to bring said computer back to a normal mode;
• determining whether the remote controller used to attempt to bring said computer to a normal mode is the same remote control device that booted said computer;
• bringing said computer back to a normal mode if said remote control device used to bring the computer back to a normal mode is the same remote control device used to boot the computer;
• and
• rebooting said computer and repeating all of the above steps if the remote control device used to bring said computer to a normal mode is different from the remote control device used to boot the computer.

A computer being operated by a remote control device, said remote control device transmitting security information to said computer to activate said computer, said computer comprising:

• a remote control signal receiver for receiving signals from said remote control device;
• a shell program for handling and transmitting said received signals from said remote control device;
• and
• a general purpose input/output unit connected between said receiver and said shell program to facilitate communication therebetween.

A method for resuming normal operation of a computer when a computer is in a standby mode, said method comprising the steps of:

• performing a screen save function;
• switching said computer from a normal operation mode into a standby state;
• pushing a button on a remote wireless device;
• transmitting security data from said remote device to said computer;
• checking whether the security data transmitted from said remote wireless device matches security data stored within said computer;
• and
• reviving said computer from said standby mode to a normal operation mode if said security data input from said remote wireless device matches said security data stored within said computer.
