A portable computer includes a chassis having a heat producing electronic component mounted therein. A heat sink is mounted in the chassis adjacent the component. A heat pipe has a first end rotatably connected to the heat sink and extends to a second end engaged with the component. The heat pipe is rotatable so as to move the second end into and out of engagement with the component.

Heat sink assembly with rotating heat pipe

A computer processor/heat sink assembly in which a heat sink is provided extending adjacent a processor or electrical component to be cooled. The heat sink has a plurality of spaced fins having openings therein and is positioned in an air flow path so that the air flows through the openings to dissipate heat from the processor to the air. The assembly can also be positioned in a second position in the air flow path so that the air flows between the fins to dissipate heat from the processor to the air.

The present invention provides a portable computer having a palm rest integrated therein that allows the user to maintain a wrist-neutral position when using the portable computer. The portable computer comprises a computer chassis having a side wall adjoining a bottom that forms a footprint of the chassis, a keyboard positioned toward a rear end of the chassis, and a cover member covering a portion of an interior of the chassis. The portable computer further includes a palm rest integrated into the structure of the portable computer's chassis. The palm rest is comprised of a palm support that has front and rear ends and that is pivotable with respect to the chassis between a covering position and an elevated first palm support position. The palm support is pivotable about a hinge, that couples the palm support to the chassis. The palm rest further includes an adjustable extension structure having a first end coupled to the palm support and a second end coupled to a wall of the chassis. The adjustable extension is pivotally coupled to the palm support adjacent a front end of the palm support.
