Please refer to the first figure. The first figure shows a block diagram of a computer system for displaying corresponding information when the host is to be powered on and turned on according to the first preferred embodiment of the present invention. As shown in the figure, the first comparison of the present invention is shown. The computer system 1 (hereinafter referred to as the computer system 1) for respectively displaying the corresponding information when the host is to be turned on and turned on can be a system composed of electronic components in the server (that is, the server itself). It can also be additionally installed in the server in the form of being integrated into the chip. The computer system 1 for displaying corresponding information when the host is to be powered on and powered on includes a host power management module 11, a processing module 12, and a display module 13, wherein the host power management module 11 is electrically connected. The processing module 12 is electrically connected to the display module 13 . In addition, the display module 13 is electrically connected to a Baseboard Management Controller (BMC) 2.

The host power management module 11 can detect and determine the operation status of the host (refer to the server in the preferred embodiments of the present invention, but not limited to other embodiments). For example, the preferred embodiment of the present invention The host power management module 11 determines whether the host is to be powered on or powered on. The manner of determining the host is, for example, based on the magnitude of the power supply voltage, but is not limited thereto. In addition, in the definition of the preferred embodiment of the present invention to be turned on, in a narrow sense, the host is in a shutdown state, and in a broad sense, the host is in an abnormal operating state, such as a sleep state or a suspended state.

When the host power management module 11 determines that the host is to be powered on, transmits a first level display power management signal S1 to the processing module 12, The first level indicates that the power management signal S1 is a low level signal (ie, a low level voltage signal).

After receiving the first level display power management signal S1, the processing module 12 processes the first level display power management signal S1, thereby outputting a first display power source S2. Specifically, the first display power source S2 is a system communication.

The system DC power is another type of power that is converted and output after the host is turned on. After the power is turned on, the system AC power and the system DC power are two power supply links coexisting, that is, after the host is powered on, the display module 13 is powered from the first display power source. S2 is converted into the second display power source S5, and if there is an external display device (not shown in the first figure), since the power consumption is large, and the power supplied by the system alternating current is small, it needs to be needed after the power is turned on. Convert system AC power to system DC power.
