Method of powering down a computer system by performing an unconditional shutdown after interrupts of first and second software systems respectively fail following a power button event

摘要

A method for powering down a computer system is shown. A power button is actuated and an interrupt is generated in response to the actuation of the power button. An unconditional shutdown of the computer system is performed on system software failing to respond to the interrupt. The system software powers down the computer system on the system software responding to the interrupt.
