, System operation. The following describes the operation flow 2 according to the third embodiment of the present invention. In this embodiment, judging the CPUs in the first and second embodiments is taken as an example. However, in this spirit, the same reasoning applies to judging other different CPUs, and it is stated here first.

2. When the power is turned on, the processing device i 丨 first outputs a message that causes the computer system to operate on the processing device 1 1 when it receives battery power. Therefore, in step S51, the computer system first sets VID 4 ~ 〇. Set to CPU ... VID 4 ~ 0, and during the boot process, the computer system judges what the value of CPU-VID 4 is at this time in step S52. Since the CPU VID value of each CPU is not the same, the CPUs in the first embodiment and the second embodiment are one. If it is the CPU in the first embodiment, the CPU-VID value is (0, 1 ,; [ , 1, 0). If it is the CPU of the second embodiment, its CPU-VID value is (1: 0: factory u}). This embodiment uses the values of CPU ... VID 4 to determine the type of the CPU. If the value of CPU-VID 4 is 0, the process proceeds to step S56, at which time the operating voltage of the computer system is 1 · 3 V. The computer system sets S W V I D 3 ~ 〇 to (1, 0, 0, 0) 'and inputs SW ... VID 3 ~ 〇 to the switching device at step s 6

Life. Next, in step S57, the computer system will detect the system ^ power supply source. If the power source is an external power source, the control device 丨 7 sets ^ HI / LO # to 1; otherwise, if the power source is a battery power source, then The control device 17 sets VR ... HI / LO # to zero. When VR HI / L〇 # is 〇; jump back to step S56, the system continues to operate at a voltage of 1.3V, and continuously detects the source of power; if VR ... ΗI / L 0 # is 1, go to step $ $ 8. 'Set v I j) q ~ 3 to SW ... VID 0 ~ 3, that is, set VID 3 ~ 〇 to (1, 0, 0, 0). At this time, the VID of the system is (〇, 1,0,0, 〇).

477925 V. Description of the invention (9) The operating voltage of the system is switched to U V. If the value of the CPU ... VID 4 is 1, the process proceeds to step S53, and the operating voltage of the computer system at this time is i. In step S53, the computer system sets yiD 3 ~ 〇 port again to (1,1, 〇, 1), and inputs Sw vi d 3 ~ 0 to the switching device 13 on standby. Then, in step S54, the computer system will detect the power supply source of the system. If the power source is an external power source, the control device HI / LO # is set to 1, otherwise, if the power source is battery power, the device is made. It means that HI / L0 # is set to 0. When the VR display is "up =! Thin", the system continues to operate at the voltage of hlV, and continues to measure the power source, the right VR --HI / L0 # is 1, then go to step S44, and change the VID. ~ 3 "Is the content of SLVID Bu 3, which will be _ 3 ~: two (, 1, 0, 1). At this time, the VI D of the system is (0, 1, 1 〇), and the operating voltage of this system is switched to 35V. Therefore, the computer system can automatically detect 2 voltage sources and automatically switch the supply system. The voltage of the "Electric House" = the trouble of the operation. ^ Eliminate the fine author Although the present invention is disclosed in the preferred embodiment as above, the invention, any person skilled in the art is not limited to the scope, should be With a few changes and embellishments, the spirit and scope of Ming Ming will be determined by the scope of the attached patent application.
