PROBLEM TO BE SOLVED: To provide a system and device of feeding a power to a personal computer capable of intensively managing the personal computer having a battery by a central control mechanism, of monitoring a charging state of each personal computer in a power saving time period to operate the personal computer by the battery in the power saving time period, and of operating the personal computer normally.SOLUTION: In a system and device of feeding power to a personal computer, a power feeding control tap in which a control circuit for controlling a power supply to be supplied for each socket of an AC power supply to the personal computer is incorporated, and the central control mechanism controlling the control circuit remotely are provided. To the personal computer, a power supply monitoring circuit monitoring a charging state of the battery is provided, and a charging state transmission circuit transmitting the charging state to the central control mechanism is arranged. In a power saving time period, the AC power supply for each personal computer is blocked by a command from the central control mechanism by using the power feeding control tap to operate the personal computer by a battery. The AC power supply is supplied in the case that the charging state of the battery is reduced to a predetermined value for each personal computer, and the battery is charged to the predetermined value, and thereafter, the AC power supply is blocked to operate the personal computer by the battery. The above process is repeated. |
