Abstract: A portable computer is provided with a clam shell case design, sealed with a sealant, form-fitted sealing units, a detachable handle, a detachable shoulder strap, and a detachable rear housing combination which increase the portability of the computer. The portability of the computer is increased because the clam shell case with sealant, and port sealing units, along with the detachable rear unit, combine for protection of the inside of the computer, including the internal circuitry, the display, keyboard, pointing device (or mouse), power cord, battery pack, extra batteries, and extra diskettes from the weather, increasing portability. The sealant waterproofs the portable computer by being placed between the top housing and the bottom portion of the portable computer, eliminating the need for a separate carrying case to hold the portable computer and to protect the portable computer from the elements. The form-fitted port sealing units protect the ports and the internal circuitry from the elements.
