    Abstract: A method to avoid over-rebooting of a power supply device comprises Step 1: receiving a power-good signal generated by a power supply device working normally; Step 2: checking whether the power-good signal is received; if no, demanding the power supply device to reboot; and Step 3: recording a count of rebootings of the power supply device; after the power supply device reboots, checking again whether the power-good signal is received; if yes, letting the power supply device keep on working and resetting the count of rebootings; if no, demanding the power supply device to reboot again, accumulating the count of rebootings, and checking whether the count of rebootings is greater than a limited count of rebootings; if yes, forbidding the power supply device to reboot. Thus is solved the problem that a power supply device whose abnormality cannot be removed by rebooting may damage the information device.

    Abstract: An inrush current recording module is installed in a power supply unit. The power supply unit has a front-stage power circuit and a back-stage power circuit. The front-stage power circuit includes a first ground terminal, and the back-stage power circuit includes a second ground terminal. The inrush current recording module includes a series circuit and a detection recording unit. The series circuit is formed by a capacitor and a resistor, and includes two ends thereof respectively connected to the first ground terminal and the second ground terminal. The detection recording unit detects the resistor to generate a voltage signal, compares the voltage signal with a voltage determination level, starts timing an inspection period when the voltage signal is greater than the voltage determination level, and records whether a current inrush current is harmful or harmless according to whether a power output signal is obtained within the inspection period.
