Abstract
A computer system having an operating system which complies with the advanced configuration and power interface (ACPI) specification comprises a temperature sensor for sensing an inner temperature of the computer system and for generating an alarm signal when the sensed temperature exceeds a predetermined value, a bridge controller for generating a system management interrupt (SMI) in response to the alarm signal, a basic input-output system (BIOS) read-only memory (ROM) for storing a power management routine, and a power management processor for receiving a power control command signal generated by the power management routine in response to the SMI, and for generating a system command interrupt (SCI). The operating system causes the computer system to enter a 'sleep' state in response to the SCI. The computer system enters the 'sleep' state when the inner temperature exceeds the predetermined value, and restores data normally when the computer system resumes operation.
