Description of the invention (7) Sense the status of each power supply to determine whether each power supply is available ( ⑽ 秘 ⑷, Another-aspect 'sensor is also connected to the predetermined voltage Vpi ~ ¥, its function and purpose will be The following is explained. The controller 42 is controlled by the sensor and can not selectively turn each switch on or off. For example, when the sensor 4! Senses that the first power source is available, That is, the control device 4 is commanded to turn on the-switch so that the-power source can: transmit to the computer system 6 and trigger the computer system 6 to enter a power management mode. In this embodiment, the power management of the computer system 6 The mode is similar to the conventional one, but the power management modes can be divided into three types according to the received first, second, and third power sources: fullspeed mode, throttling mode, and Hibernate mode. Full-speed mode means that computer system 6 operates in normal mode, that is, all components in computer system 6 (such as processor, hard disk, memory ...) are supplied with power for normal operation. The throttling mode is similar to the full speed mode, but the 15 processor in computer system 6 is forced to change. The lower speed operation mode can reduce power consumption and enable computer system 6 to operate for a long time under a fixed power supply. . The hibernation mode allows the system to maintain a short period of time, and the system automatically shuts down after the system automatically stores the data in the memory (RAM) in a compressed form on the hard disk. Of course, the controller 42 can also receive the request from the computer system 6 and turn on or off the power source. For example, when the user presses the power start button on the host computer, the computer system 6 sends out the controller 42. The requirement to turn on the power causes the controller 42 to control the switching device 3, so that the power can be transmitted to the computer system 6. When the user uses the operating system to make the computer system 6 request to turn off the power, the controller 42 controls the switching device. Page 10 576443 10 15 20 A7 B7 V.
