Abstract

A laptop computer includes a wireless pointer device which is located within the base of the laptop. In an exemplary embodiment, the pointer device is an infrared mouse designed to fit within a cradle mechanism. In one example, the cradle mechanism is located centered and below the keyboard and may be inserted in, and replace, the space generally used for the touch-pad surface of a touchpad pointer system. The mouse is recharged when engaged with the cradle mechanism. The cradle mechanism may be selectively opened to release the wireless mouse or pointer device for use in interacting with the laptop computer.
