Abstract: A machine implemented method includes creating a universally unique identifier, detecting a trigger of a sleep event, and associating the universally unique identifier with the sleep event. The method monitors sub-system events that occur after a sleep event has been triggered and stores data in non-volatile non-disk storage (e.g., non-boot storage) identifying an event stage corresponding to the sub-system event that is occurring. The method determines whether a wake event has completed and logs each of the sub-system events using the universally unique identifier until a wake event has completed.

Abstract: One embodiment of the present invention provides a system that enables a computing device to save additional power by entering a “hibernation mode,” wherein the active state of the computing device is preserved in non-volatile storage while power to volatile storage is turned off. During operation, the system reanimates a computing device from a hibernation image by restoring reanimation code from the hibernation image and then executing the reanimation code. While executing this reanimation code, the system restores the rest of the hibernation image by, reading compressed data containing the rest of the hibernation image, and decompressing the compressed data using computational circuitry within the computing device. During this process, the decompression operations are overlapped with the reading operations to improve performance.

Abstract: A system that causes a computing device to enter a hibernation mode. During operation, the system creates a hibernation image for the computing device by identifying processes that do not have visible user interface elements, and generating the hibernation image so that processes with visible user interface elements can be reanimated from the hibernation image first to get the computing device reanimated quickly, while the identified processes are reanimated later. Next, the system stores the hibernation image in non-volatile storage. The system then causes the computing device to enter the hibernation mode, wherein the active state of the computing device is preserved in non-volatile storage while power to volatile storage is turned off.
