The transparent display screen has a black border coincident with a peripheral portion of the screen. The rear surface of the computer is black. The portion of the computer shown in gray shading represents a metallic-looking surface that preferably contrasts with the black portions.

All broken lines represent environmental subject matter that forms no part of the claimed design.
