Infrared signal processing devcie and computer

Abstract

An infrared signal processing device includes an infrared signal receiver to receive infrared signals from a handheld remote control and a signal generating circuit connected to a power management unit of a motherboard of a computer via a cable. The device further includes a prompting unit to output a prompt and a processor to decode the infrared signals received by the infrared signal receiver. The processor controls the prompting unit to output a prompt to prompt a user to input a password when determining that the infrared signal received by the infrared signal receiver is a startup command or a shut down command. When an inputted password matches with a preset password, the processor controls the signal generating circuit to generate a control signal and send the control signal to the power management unit to start or shut down the computer as required.
