Abstract

Embodiments of the invention provide for operating a handheld computer with multiple time-out periods in a manner that is more efficient and effective for conserving power than previous systems. In an embodiment, the handheld computer implements one or more additional time-out periods by identifying an occurrence of an event that requires the handheld computer to be in the high power state to perform a specific function. An event may include a function such as sounding an alarm, although other events are also encompassed by embodiments of this invention. When an event is identified, the power state of the handheld computer prior to identifying the event is recalled. The handheld computer then implements a time-out period based on its previous power state. In one embodiment, if the handheld computer was in a low-power state prior to the event occurring, the time-out period is shortened.
