FAST COMPUTER STARTUP

摘要

Fast computer startup is provided by, upon receipt of a shutdown command, recording state information representing a target state. In this target state, the computing device may have closed all user sessions, such that no user state information is included in the target state. However, the operating system may still be executing. In response to a command to startup the computer, this target state may be quickly reestablished from the recorded target state information. Portions of a startup sequence may be performed to complete the startup process, including establishing user state. To protect user expectations despite changes in response to a shutdown command, creation and use of the file holding the recorded state information may be conditional on dynamically determined events. Also, user and programmatic interfaces may provide options to override creation or use of the recorded state information.

主权项

1. A method performed on a computing device, the method comprising:
detecting, by the computing device during a startup process of the computing device, a hibernation file that was created during a preceding shutdown process of the computing device, where the detected hibernation file stores a system state and first hardware configuration of the computing device as existing on the computing device at a first time of the preceding shutdown process; determining, by the computing device, that a second hardware configuration of the computing device at a second time of the startup process remains compatible with the first hardware configuration of the computing device at the first time of the preceding shutdown process; and restoring, by and to the computing device in response to the determining that the second hardware configuration of the computing device remains compatible with the first hardware configuration of the computing device, the system state of the computing device stored in the detected hibernation file, where the system state being restored is a part of the startup process of the computing device.
