Abstract
A portable computer incorporates an AC adaptor for providing DC power to the portable computer. Especially, the adaptor is configured to be housed within or detached from the battery pack-receiving bay of the portable computer. Preferably, the AC adaptor includes a second connector electrically connectable to a first connector provided in the battery receiving bay, to form appropriate electrical connection. Also, the AC adaptor has the same configuration as the battery pack. Further, the AC adaptor has a DC jack for receiving a DC plug, and for outputting the DC power at the side of the adaptor provided with said second connector. The DC jack may also be provided on the side of the adaptor opposite to the second connector, when the AC adaptor is mounted in the battery receiving bay. With this arrangement, use of the portable computer becomes more convenient by incorporating the battery pack in a detachable way. Further, when the AC adaptor is installed instead of the battery pack, the continuous usage of the battery pack, i.e., frequent charging/discharging of the battery can be prevented, and thus poor performance and shortening of the battery life can be effectively prevented.
