Patent ID: 8370615

Claim:
A hard disk temperature monitoring device, suitable for monitoring a temperature of a hard disk in a computer system, comprising: a hard disk, storing an operating system; a basic input/output system (BIOS), having a setting configuration, wherein when the setting configuration is a first setting value, operation of the hard disk is restored, and when the setting configuration is a second setting value, the operation of the hard disk is stopped; a thermal sensor, sensing a temperature of the hard disk; and a keyboard controller (KBC), electrically connected to the thermal sensor via a data transmission channel for detecting the temperature of the hard disk, wherein when the KBC detects that the temperature of the hard disk rises to a first predetermined temperature, the setting configuration of the BIOS is set to the second setting value, and the BIOS stops the operation of the hard disk according to the second setting value, wherein if the KBC detects that the temperature of the hard disk rises to the first predetermined temperature, the KBC sends an interrupt signal to the BIOS, and wherein the interrupt signal is a system management interrupt event (SMI event), and after receiving the SMI event, the BIOS enters a system management interrupt routine (SMI routine) to enable the operating system to enter a freeze mode.
