Abstract
A system and method for enabling a computer system to cascade from the suspend state to the zero volt suspend-to-disk state. The system and method uses the computer system's real time clock (RTC) to provide an alarm indicating when the computer system should enter the suspend-to-disk state. The RTC is used because this device is active even when the computer system is in an ultra low power state, such as the suspend state. The present invention also includes a method which prevents the power management or system management software from interfering with other application's use of the RTC alarm.
