Abstract

A portable computer includes a portable computer body having an upper surface, a lower surface and a lower front edge thereof. An add-on battery is detachably mounted on the lower surface of the portable computer body and has a wedge-shaped portion corresponding to a wedge-like space which is defined between the lower surface of the portable computer body and a surface on which the portable computer body is placed, when the portable computer body is placed to be inclined about the lower front edge of the portable computer body. The portable computer body is, when it is equipped with the add-on battery, inclined in such a manner that the upper surface of the portable computer body is lower at a front edge thereof.

Claims

1. A portable computer supportable on a support surface, comprising:

a portable computer body having upper and lower main surfaces joined by corresponding front and rear edges;

a battery detachably connectable at an upper surface thereof to the lower main surface of the portable computer body adjacent the rear edge thereof and maintaining the rear edge elevated with respect to the front edge, relatively to a support surface on which the portable computer body, with the battery detachably connected thereto, is supported; and

said upper surface of the battery being in contact with said lower main surface of the portable computer body within a region thereof adjacent the rear edge, when said battery is connected to the portable computer body.
