Abstract
A portable computerhas a first metallic portionand a second metallic portion, and an expansion devicehas a first magnetand a second magnet, whereby the expansion devicecan be attached to a predetermined position of the portable computerusing attractive forces generated by the magnets. Therefore, when the portable computerto which the expansion deviceis attached is dropped mistakenly on a floor, etc., and the impact is applied on the expansion device, the expansion deviceis separated from the portable computereasily. Thus, even if the expansion deviceis damaged, the impact to be transmitted to the portable computercan be reduced by separating the expansion devicefrom the portable computer, which reduces damage to the portable computer
