A write filter is used to handle write operations by an operating system of a computing device that has a main storage medium in which the operating system image is stored. The write filter is placed in the operating system to intercept write commands for writing state data into the main storage medium and to write the state data onto a non-volatile auxiliary storage medium to prevent the state data from being lost when the device is shut down. The write filter creates checkpoints (or watermarks) for the state data in the non-volatile memory to protect them from being written over and to allow the system to roll back to a previous state. The write filter also enables the operating system image in a writable main storage medium of the computing device to be replaced with a new operating system image while the operating system is still running through by gradually copying the new image into the main storage while moving the old image into a look-aside buffer in the RAM.

A shutoff condition monitoring method for a computer, includes the steps of: a) determining that an abnormal shutoff has occurred when the computer shuts off without passing through predetermined shutoff processing; b) counting the number of times of repetitive occurrences of the abnormal shutoff; and c) determining that predetermined recovery processing should be carried out on the computer when the number of times of repetitive occurrences of abnormal shutoff exceeds a predetermined value.

The computer system initially operates in a fully operational mode in which an operating system in the computer system is operating and the computer system executes one or more user applications installed in the computer system. In response to a predefined time interval lapsing, the computer system automatically switches from the fully operational mode to a limited operational mode in which the one or more user applications are terminated, the operating system is shut down, and a BIOS within the computer system solicits entry of a password by a user. If the user fails to enter a valid password, operation of the operating system and execution of the one or more user applications are prevented. If a user attempts to activate the computer system for which the time interval has already lapsed, a BIOS within the computer system boots up, determines that the computer system is currently set for a limited operational mode, prevents boot up of an operating system of the computer system, and solicits a password from a user. If the user fails to enter a valid password, the BIOS continues to prevent boot up of the operating system. If the user enters a valid password, the operating system boots up and executes one or more user applications within the computer system.

The invention discloses a terminal starting control device. The device comprises a detecting module, an inquiring module and a control module. The detecting module is used for detecting the state change under the shutdown situation. While the detecting module detects the state change of the terminal under the shutdown situation, the inquiring module inquires the previous shutdown reason of the terminal. The control module controls the starting situation of the terminal according to the different shutdown reasons. The invention further discloses a terminal starting control method. The technical solution is capable of reducing the user operation about the starting problem of the terminal, and improving the user experience. The operation is more humanized.
