A laptop also known as a notebook is a personal computer designed for mobile use small enough to sit on one's lap. A laptop includes most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touch pad, also known as a track pad, and/or a pointing stick), speakers, as well as a battery, into a single small and light unit. The rechargeable battery required is charged from an AC/DC adapter and typically stores enough energy to run the laptop for two to three hours in its initial state, depending on the configuration and power management of the computer.
