Abstract
A computer system and a bootup and shutdown method thereof are provided. The computer system includes a memory, a chipset, a basic input/output system (BIOS), and an embedded controller, and an operating system (OS) is executed in the computer system. In the shutdown and bootup method, the embedded controller is notified to prepare to enter into a standby mode when the BIOS intercepts a shutdown instruction issued by the OS. The content of a register of the chipset is set according to the standby mode. A current operation mode data of the computer system is retained, and power is continuously supplied to the memory to make the computer system enter into the standby mode.
