APPARATUS AND METHOD FOR RE-BOOTING A SYSTEM UNDER INCIDENT POWEROFF IN PC

摘要

One device and a kind of method, even if for restarting a kind of incidental parking generation of a power code that system is arranged to that normally and promptly PC will not be separated from power supply under the incidental parking of a PC in PC restarting systems. One SMPS (Switching Power Supply) (110) is generated and is provided multiple operation voltages required for one PC of operation, and a monitoring device checks whether that the output of SMPS is normal or abnormal. When anomaly occurring in the output of SMPS, a reset signal supplier resets a system wake-up module (120). Monitoring device includes a glitch detector (130), detects a glitch signal when exception occurs from SMPS in power supply output, is changed by the glitch signal that response detects and export one predetermined time of level of an output signal. One reset signal supplier includes one and door (140), is used for the output signal in monitoring device and exports an AND operation between the reset signal from a System Management Controller (100).
