ABSTRACT:
A portable computer (40) has an integrated motherboard/keyboard/housing assembly (48) wherein the keys (50) are disposed through the motherboard (54) to contact a keyboard circuit (56) on the upper surface of the bottom layer of the main housing(44). During a keystroke, the key travels within a hole (52) in the motherboard (54), which also acts as a guide to the key. Accordingly, weight and height associated with separate assemblies is greatly reduced.
