Embodiment Construction

[0015] In order to improve the flexibility of the power management in the computer system, the present invention adds a mechanism for the user to set the shutdown mode of the embedded controller (such as the keyboard controller) according to the needs.

[0016] For details, please refer to figure 1 , figure 1 It is a schematic diagram of a power management process 10 according to an embodiment of the present invention. The power management process 10 can improve the flexibility of power management in a computer system, which includes the following steps:

[0017] Step 100: start.

[0018] Step 102: Generate a setting command CMD_SET for setting a flag F (Flag) of an embedded controller of the computer system to a first value V1 or a second value V2. If the flag F is equal to the first value V1, execute step 104; otherwise, if the flag F is equal to the second value V2, execute step 106.

[0019] Step 104: Switch the embedded controller to a deep sleep mode when the compute...

Abstract

The invention relates to a power supply management method and a computer system. The power supply management method is used for promoting the flexibility of power supply management in the computer system and comprises the following steps: generating a setting instruction; guiding an embedded controller of the computer system to switch to a deep sleep mode or a dead halt mode when the computer system is powered off; in the deep sleep mode, the embedded controller consumes specific electric quantity and the initialization is not executed when the embedded controller is restarted; and in the dead halt mode, the embedded controller consumes no power and the initialization is executed when the embedded controller is restarted. By using the method provided by the invention, the flexibility of power supply management in the computer system is promoted.

Description

technical field [0001] The invention relates to a power management method and a computer system, in particular to a power management method and a computer system capable of improving the flexibility of power management in a computer system. Background technique [0002] Notebook computers have the characteristics of small size, light weight, and easy portability, which allow users to easily work outside the office and use various functions of the computer system without being restricted by bulky desktop computers. before the desktop. In order to be convenient for users to carry with them, notebook computers are all equipped with rechargeable batteries for storing power, so as to provide power required for operation. Since the power stored in the rechargeable battery is limited, when the power of the rechargeable battery is exhausted, the user must replace the battery with sufficient power or use other power sources to continue using the notebook computer. [0003] Therefor...
