Electrical apparatus, computer, and power switching method
First Claim
1. An electrical apparatus, comprising:
- a body that consumes a power;
a power source that powers said body with a power received from a commercial power source; and
a battery that repeats charging and discharging to power said body;
wherein said power source is used to drive a predetermined subsystem selected from a plurality of subsystems and said battery is used to drive other subsystems of said body.

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.

15. A power supplying method that enables a body to be powered by both of a power source connected to a commercial power source and a battery that repeats charging and discharging while said body is connected to said power source and said battery respectively, said method comprising:
-
enabling said power source to power a predetermined subsystem of said body; and
enabling said battery to power other subsystems of said body while said power source powers said predetermined subsystem. - View Dependent Claims (16)

17. A power supplying method that enables a body to be powered by a power source connected to a commercial power source and a battery that repeats charging and discharging while said body is connected to both of said power source and said battery, said method comprising:
-
deciding whether or not a peak power reduction time set for said commercial power source is reached; and
enabling said battery, when said time is reached, to power said predetermined subsystem and said power source to power other subsystems of said body. - View Dependent Claims (18)
