Abstract
When a computer system's power button is depressed a timer is begun, an operating system visible status flag is set, and an interrupt is sent to the operating system indicating power button activation. If the operating system does not clear the flag within a specified time period, the computer system is considered to be in an error (e.g., "hung" state) and the computer system is powered down.
