Abstract: A power management system and a power management method for a main system are provided. The power management system includes plural battery units and a charging management unit. A charging rule is executable by the charging management unit. The charging management unit is electrically connected with the plural battery units and the main system to dynamically detect electric quantities of the respective battery units and a system consumption power level of the main system. The charging management unit calculates a system surplus supply power level according to a system supply power level and the system consumption power level. The charging management unit dynamically adjusts charging capacities of the respective battery units according to at least one of the electric quantities, the system surplus supply power level and the charging rule.

Abstract: A USB detecting method for use with a controlling and processing unit, a USB input/output port, at least one switch and at least one USB peripheral device is provided. The at least one switch is arranged between the controlling and processing unit and the USB input/output port and/or arranged between the USB input/output port and the at least one USB peripheral device that is electrically connected with the USB input/output port. Firstly, a USB detection signal of the at least one USB peripheral device is provided to the controlling and processing unit. According to a result of receiving the USB detection signal, the controlling and processing unit determines whether the switch is reset. For resetting the at least one switch, the controlling and processing unit simulates the action of plugging and pulling out the USB peripheral device.
