Abstract: A method for remote diagnosis for hardware, generating a trigger command by a remote management device comprising a plurality of candidate commands for triggering a baseboard management controller when the remote management device receives a user command, and sending a executing command to a BIOS by the triggered baseboard management controller; performing a diagnosis process and generating a diagnosis message according to the diagnosis process based on a boot code of the BIOS by the server, and then sending the diagnosis message to the baseboard management controller by the BIOS. Storing the diagnosis message by the baseboard management controller, and sending a feedback command to the remote management device after the baseboard management controller stores the diagnosis message, and then generating a feedback message by the remote management device.

Abstract: A temperature-controlling method adapted to a server comprises: getting a detected temperature; selecting a schedule from a plurality of schedules according to the detected temperature by a gain-scheduling unit, wherein the plurality of schedules comprises an initial parameter set and at least one cooling parameter set; calculating and outputting a control signal of fan speed according to the initial parameter set or said at least one cooling parameter set by a PID controller; and adjusting a rotating speed according to the control signal of fan speed by a fan.
