ABSTRACT:
An abnormal power interruption internal circuitry protection method and system is proposed for use with a computer platform, such as a blade server, which is characterized by the utilization of each server module's identification code (i.e., blade ID signal) and power-good signal to judge whether each server module is subjected to an abnormal power interruption, such that in the event of the abnormal power interruption, a small amount of remnant electrical power left in the internal circuitry of the blade server can be fetched as power source to shut down the server modules through a normal shutdown procedure. This feature can help protect the internal circuitry of the server modules of the blade server from being damaged due to abnormal shutdown in the event of abnormal power interruption.
