ABSTRACT:
An electrically powered apparatus having a system body obtains power from an AC adapter connected to the system body. The system body and AC adapter are powered from a commercial power source. A battery connected to the system body is charged, then discharged to power the system body. An embedded controller suppresses power supplied from the AC adapter on a predetermined condition while both the AC adapter and the battery are connected to the system body. In a peak shifting time zone, switches are opened to enable the battery to power the system body. When the capacity of the battery is insufficient, a switch is closed to enable the AC adapter to power an inverter. When the capacity of the battery is still insufficient, another switch is closed to enable the AC adapter to power the CPU.
