Abstract
An electrical apparatus including an AC adapter 51; a battery 52 that repeats charging and discharging to power the apparatus; an AC/DC enable circuit 61 that switches between stop and start of power source from the AC adapter 51 to the body; a charger utilization circuit 62 that charges an output capacitor (Cout) of a charger 60 while the power source from the AC adapter 51 stops; and a battery detection circuit 63 that detects disconnection of the battery 52. If the battery 52 is disconnected from the body and the battery detection circuit 63 detects the disconnection while the power source from the AC adapter 51 stops and the body is powered by the battery 52, the AC/DC enable circuit 61 starts power source to the body while the body is powered by the output capacitor (Cout).
