Abstract

The present invention features a personal computing device that may be powered by a single battery having a single lithium-ion cell or by a plurality of lithium-ion cells connected in parallel. The personal computing device may provide computing power comparable to that of conventional laptop computers and execute an operating system and application software comparable to that executed by conventional laptop computers. Furthermore, the battery'"'"'s time between charging, when used to power the personal computing device, may be similar to the time between charging of a multi-cell battery when used to power a conventional laptop computer.
