Question pretext
A Laptop or notebook computer is defined as a portable computer small enough to use in your lap. This is the same as a notebook computer which is defined as an extremely lightweight personal computer <http://www.webopedia.com/TERM/N/personal_computer.html>. Laptop or Notebook computers <http://www.webopedia.com/TERM/N/computer.html> typically weigh less than 6 pounds and are small enough to fit easily in a briefcase. A laptop integrates most of the typical components <http://en.wikipedia.org/wiki/Computer_hardware> of a desktop computer <http://en.wikipedia.org/wiki/Desktop_computer>, including a display <http://en.wikipedia.org/wiki/Computer_display>, a keyboard <http://en.wikipedia.org/wiki/Computer_keyboard>, a pointing device (a touchpad <http://en.wikipedia.org/wiki/Touchpad>, also known as a trackpad, and/or a pointing stick <http://en.wikipedia.org/wiki/Pointing_stick>), speakers, and often including a battery, into a single small and light unit. The rechargeable battery <http://en.wikipedia.org/wiki/Rechargeable_battery> (if present) is charged from an AC adapter <http://en.wikipedia.org/wiki/Electronic_power_supply> 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. NOTE: Smartphones, IPads, Kindles or other PDA (Personal digital assistant devices) etc are not included here.
