Abstract: A portable computer includes a display portion comprising a display and a base portion pivotally coupled to the display portion. The base portion may include a bottom case and a top case, formed from a dielectric material, coupled to the bottom case. The top case may include a top member defining a top surface of the base portion and a sidewall integrally formed with the top member and defining a side surface of the base portion. The portable computer may also include a sensing system including a first sensing system configured to determine a location of a touch input applied to the top surface of the base portion and a second sensing system configured to determine a force of the touch input.

Abstract: A base plate includes a planar member. Two rods extend from the planar member, each of the rods having a free end. A battery includes two bores there-through, the bores positioned and configured to receive the rods when the battery is positioned on the planar member. Two first terminals protrude from the planar member. Two second terminals are recessed within the battery and are configured and positioned to contact the first terminals when the battery is positioned on the planar member. Two third terminals are configured for connection to a vehicle's battery cables and are electrically connected to the first terminals. A cap threadedly connects to the free end each rod to secure the battery on the base plate.
