By being embedded in a portable computing device, a battery pack is made essentially inaccessible to unauthorized users, thereby allowing for a battery pack that can be made smaller and of lighter construction material, thereby facilitating greater component density within the portable computing device, lower cost to manufacture, and more environmentally secure. In another embodiment, the battery pack can take the form of a battery assembly formed of a single piece housing having a cantilever portion to provide additional stiffness.
