1. An information handling system comprising:
- a housing;
plural processing components disposed in the housing and operable to process information;
a cover coupled to the housing and operable to between an open position and a closed position;
a display integrated in the system, the display visible to a user in the open position and protected from view in the closed position;
a switch associated with the cover and housing and interfaced with the processing components, the switch operable to detect whether the cover is in the open position or closed position and to communicate the detected cover position to the processing components;
a power manager associated with the processing components and operable to alter the operation of the processing components when the detected cover position changes from the open position to the closed position; and
a cover delay module interfaced with the power manager and operable to delay the power manager from altering the operation of the processing components by predetermined amount of time after the cover position changes from the open position to the closed position;
wherein the processing components comprise a BIOS, the switch interfaces with the BIOS, the BIOS communicates the detected position to the power manager and the power manager comprises an operating system module, and wherein the cover delay module delays the power manager by delaying communication of the detected position to the power manager.

Abstract
Power down to a reduced power state, such as a standby or off state, of an information handling system is delayed by a user-configured time after detection of closing of the cover of the information handling system. In one embodiment, a cover delay module associated with the BIOS of the information handling system delays communication of the detection of the closing of the cover from the BIOS to a power manager of the operating system that commands the reduced power state. In another embodiment, the cover delay module integrates with the operating system power manager.

8. A method for managing portable information handling system operational states, the method comprising:
-
placing the information handling system in an active state having a lid in an open position; closing the lid; delaying a change from the active state for a predetermined time; and initiating a reduced power state in response to the closing of the lid following the passing of the predetermined time; wherein delaying a change further comprises delaying communication of a power down signal from a switch that detects closing the lid to an operating system that initiates the reduced power state. - View Dependent Claims (9, 10, 11, 12, 13)

14. A system for managing portable information handling system operational states, the portable information handling system having a housing and a cover, the cover having open and closed positions, the system comprising:
-
a switch operable to detect the closed position; a power manager interfaced with the switch and operable to transition the portable information handling system to a reduced power state if the switch detects transition from the closed position to the open position; and a cover delay module interfaced with the power manager and operable to delay transition to the reduced power state in response to the transition to the closed position by a predetermined time after transition to the closed positions; wherein the cover delay module comprises a firmware module interfaced with the switch and operable to delay communication from the switch to the power manager of detection of the closed position. - View Dependent Claims (15, 16, 17)
