Abstract
A computer system enters or exits a sleeping state, such as the ACPI “S1” state, in response to a sleep or wake event. Upon detecting the sleep or wake event, a system component generates a sleep or wake signal that instructs the computer to enter or exit the sleeping state. This sleep or wake signal is of a type to which the computer's processor does not respond. Therefore, a PMI signal is asserted in response to the sleep or wake signal. The PMI signal, when asserted, causes the processor to halt program execution.
