Abstract: A system and method is disclosed for adjusting power consumption of a computing device. The computing device is configured with one or more sensors to sense when a user moves away and returns to the computing device. Over a period of time, the computing device determines a pattern of activity related to how long the user is normally away from the computing device during particular times of the day. The computing device may then adjust power consumption of the device or associated components during times of the day for which a pattern of activity has been determined. For example, the computing device may adjust a duration that the computing device will remain idle before power to the computing device is limited.

Abstract: A computing device may detect the presence of a user after the user has not interacted with the computing device for a predetermined time period. The user may leave the device powered up, but after the predetermined time period has expired, the device enters a user detection mode from a normal operation mode such that nonessential components are powered down. A trackpad may be used to detect the presence of the user in the user detection mode. An electric field is generated by conductive plates of the trackpad. When the user extends his hand over the trackpad, sense lines in the track pad detect the interference with the electric field caused by the hand. A processor is signaled to return the device normal operation mode and restore full power to the device. A camera may be also used to detect the user's presence during the user detection mode.

Abstract: The surface of an touch-sensitive input device may act as a physical button that the user may push down to perform a click or other operation. For example, the user may push down the surface of the input device with one finger for a left click and push down the surface of the input device with two fingers for a right click. In one aspect, a system for detecting a left click or a right click when the user pushes down the surface of the input device is provided. When the system first detects that the surface of the input device is pushed down, the system may wait for a short period of time before making a determination of whether the user is pushing down the surface with one finger or two fingers. During this time, the system may collect additional information to make a more reliable determination.

Abstract: A system and method is disclosed for recovering a boot image from a secure location. Hardware instructions initiate a sequence of boot cycles to launch a computer operating system on a computer-enabled device. During the boot cycles, multiple levels of boot code are verified and a determination is made whether each level is usable by the device. If a level of boot code is determined to be unusable, a secure copy of the boot code is loaded from a secure read-only location to repair the unusable code to launch the computer operating system.
