COMPUTER SYSTEM AND METHOD FOR RESETTING THE SAME
First Claim
1. A method for resetting a computer system, the computer system comprising a basic input output system (BIOS) chip and a keyboard controller, and the method for resetting the computer system comprising:
- monitoring the keyboard controller by the BIOS chip to determine whether a time that the keyboard controller remains in a hang up state reaches an idle time limit;
monitoring the BIOS chip by the keyboard controller to determine whether a time that the BIOS chip remains in the hang up state reaches the idle time limit; and
when it is determined that the time of one of the BIOS chip and the keyboard controller remaining in the hang up state reaches the idle time limit, triggering a hardware reset signal by the other one of the BIOS chip and the keyboard controller to reset the computer system.

Abstract
A computer system and a method for resetting the same are provided. The computer system includes a basic input output system (BIOS) chip and a keyboard controller. In the method, the BIOS chip monitors the keyboard controller to determine whether a time that the keyboard controller remains in a hang up state reaches an idle time limit. Besides, the keyboard controller monitors the BIOS chip to determine whether a time that the BIOS chip remains in the hang up state reaches the idle time limit When it is determined that the time of one of the BIOS chip and the keyboard controller remaining in the hang up state reaches the idle time limit, the computer system is reset in accordance with a hardware reset signal trigger by the other one of the BIOS chip and the keyboard controller.

6. A computer system, comprising:
-
a power management circuit, managing a power of the computer system; a basic input output system (BIOS) chip, coupled to the power management circuit; and a keyboard controller, coupled to the power management circuit and the BIOS chip, wherein the BIOS chip monitors the keyboard controller to determine whether a time that the keyboard controller remains in a hang up state reaches an idle time limit, and the keyboard controller monitors the BIOS chip to determine whether a time that the BIOS chip remains in the hang up state reaches the idle time limit, when it is determined that the time of one of the BIOS chip and the keyboard controller remaining in the hang up state reaches the idle time limit, the other one of the BIOS chip and the keyboard controller sends a hardware reset signal to the power management circuit to control the power management circuit to turn off and then turn on the power of the computer system. - View Dependent Claims (7, 8, 9, 10, 11, 12)
