Apparatus and method for reducing impact-induced shock and vibration in a portable computer

The disclosures herein relate generally to computer systems and more particularly to an apparatus and method for reducing impact-induced shock and vibration in a portable computer. A portable computer housing including an enclosure with a support wall and a strike zone including a first protrusion in the support wall. A support member is attached to the enclosure. The support member includes a base wall positioned in close proximity to the support wall of the enclosure. A second protrusion is formed in the base wall of the support member. The second protrusion is offset from the base wall by a first distance with at least a portion of the second protrusion being received within the first protrusion. A recess in the second protrusion is offset from the base wall by a second distance. The second distance is less than the first distance. The potential for impact-related failure of components in the portable computer is greatly reduced. Also, the configuration of the strike zone reduces the magnitude of the shock from an impact and eliminates a portion of the high frequency content that is known to damage components such as the hard drive.
