Abstract

Two battery packs are loaded into respective loading portions, and serve to deliver power to respective units of a personal computer through a port and are supplied with power through the port from an AC adapter connected to an AC power supply so that they are charged. Each lock portion serving as a loading mechanism includes a switch interlocking therewith. Output of the switch is delivered to a CPU serving as a mode control unit. The CPU controls a CPU serving as a switch control unit within the battery pack in correspondence with loading state of the battery pack inputted from the switch interlocking with the lock portion to switch operation mode of the battery pack. Thus, it is possible to prevent instantaneous cut-off of power supply at the time of removal of battery without allowing the apparatus to be complicated, and/or without allowing the cost to be high.
