Abstract: A power management method is adapted for a computer system that includes a CPU, a control unit, a BIOS and multiple PSUs. When one PSU operates abnormally, it sends an alert signal that is in an alert state to the control unit, and the control unit causes the CPU to operate under a predefined lowest power consumption limit. The control unit computes an updated power consumption limit, and notifies the BIOS to write the updated power consumption limit into a model-specific register of the CPU, so as to make the CPU operate under the updated power consumption limit.

The adjustment plate is movably connected to the panel for connecting a rear support post and is adjustable to suit varying distances between front and rear support posts. The rails are detachably mounted on the panel; a gap between two rails is adjustable to accommodate different server devices.

Abstract: A method for protecting a server from damage by a liquid leak from a liquid-cooling unit of the server is provided. The server further includes a liquid leak sensor unit, a programmable logic circuit, and a power supply unit that supplies main power and standby power for the server. When a liquid leak is detected, the liquid leak sensor unit generates a main-power-off signal to the programmable logic circuit that causes the power supply unit to stop outputting the main power accordingly. The liquid leak sensor unit sends a total-power-off signal to the power supply unit to stop supply of the standby power after the power supply unit has stopped outputting the main power.

Abstract: A system includes a host and a display. The host includes a programmable logic device (PIP), a baseboard management controller (BMC) and a switch. The PLD performs a power-on procedure based on a power-on sequence code, generates variable character information in the power-on procedure, and fills the variable character information into a variable field in a preset log text file to result in an updated log text file. When it is determined that the power-on procedure is not normally completed, the PLD controls the switch to switch to a debug mode, and transmits a video signal containing debug information corresponding to the updated log text file to the switch so that the video signal is outputted to the display.
