Abstract: An update method for a basic input/output system (BIOS) and an update system thereof are provided. Firstly, a program code of a boot block included in a main BIOS block is executed to detect whether the main BIOS block is crashed. A program code of the BIOS is stored in the main BIOS block. A BIOS image file is searched from a storage device when the main BIOS block is crashed, which includes a program code of a graphical user interface (GUI) and a plurality of update files. The program code of the GUI is executed to display graphic updating information of the BIOS. One of the update files is selected by a control command to update the main BIOS block. Therefore, the needed update file can be selected to update the BIOS by graphically display the updating information of the bios, thereby improving the update efficiency and usage convenience.

Abstract: First, an application program is executed on a computer, and then a virtual sleep request is received. Next, the configuration of a CPU, built in the computer, is saved to a RAM. Finally, both the processing speed and the core voltage of the CPU are reduced, and the application program originally executed on the computer continues to run.
