Computer system having remote wake-up function and remote wake-up method thereof

Abstract

A computer system having a remote wake-up function capable of storing confidential information, and a remote wake-up method thereof. The computer system having a remote wake-up function includes: a network information storage portion for storing network information including a network address and a password; and a magic packet controller for receiving a magic packet via a physical layer portion, comparing a network address and a password which are contained in a magic packet, with the network address and the password stored in the network information storage portion, and generating a wake-up control signal to transfer to a power management unit of the computer system only when the compared network addresses and passwords are the same each other, wherein the computer system suspended is booted by the wake-up control signal. Therefore, when waking up remotely the computer system via a network, it is determined whether or not such remote waking up is by an authorized supervisor system. As a result, the computer system can be prevented from having information stolen therefrom by a user with bad intentions. Also, as a further result, the computer system can avoid becoming damaged by a user with bad intentions.
