A laptop computer, or simply laptop (also notebook computer or notebook), is a small mobile computer, which usually weighs 2-18 pounds (1-6 kilograms), depending on size, materials, and other factors.
A laptop computer is much smaller than a desktop. Laptops usually run on a single main battery or from an external AC/DC adapter which can charge the battery while also supplying power to the computer itself. Many computers also have a 3 volt cell to run the clock and other processes in the event of a power failure.
As personal computers, laptops are capable of the same tasks as a desktop computer, although they are typically less powerful for the same price. They contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and efficient power consumption. Laptops usually have liquid crystal displays and most of them use different memory modules for their random access memory (RAM), for instance, SO-DIMM in lieu of the larger DIMMs. In addition to a built-in keyboard, they may utilize a touchpad (also known as a trackpad) or a pointing stick for input, though an external keyboard or mouse can usually be attached.
A Tablet PC is a notebook- or slate-shaped mobile computer. Its touchscreen or digitizing tablet technology allows the user to operate the computer with a stylus or digital pen, or a fingertip, instead of a keyboard or mouse.
The form factor offers a more mobile way to interact with a computer. Tablet PCs are often used where normal notebooks are impractical or unwieldy, or do not provide the needed functionality.

The company was established in 1935 under the name Fuji Tsūshinki Seizō (富士通信機製造, Fuji Telecommunications Equipment Manufacturing), a spinoff of the Fuji Electric Company, this in turn being a joint venture between the Furukawa Electric Company and German conglomerate Siemens founded in 1923. Despite its connections to the Furukawa zaibatsu, Fujitsu escaped the Allied occupation of Japan mostly unscathed.
In 1954 Fujitsu manufactured Japan's first computer, the FACOM 100, and in 1961 the transistorized FACOM 222. In 1967, the company's name was officially changed to the contraction Fujitsū (富士通).
In 1955, Fujitsu founded Kawasaki Frontale (川崎フロンターレ, Kawasaki Furontāre) as a Fujitsu soccer club. Kawasaki Frontale has now been a J. League football club since 1999.
After 1981 Fujitsu gradually took over International Computers Ltd (ICL) in the UK, ultimately becoming Fujitsu Services in 2002. ICL Inc, the US subsidiary was founded in 1992 and was renamed to Fujitsu Transaction Solutions in 2002. This division provides Point of Sale computing products to retailers and service of equipment.
From February 1989 until the Summer of 1997 Fujitsu built the FM Towns PC variant. It started as a proprietary PC variant intended for multimedia applications and computer games, but later became more compatible with regular PCs. In 1993, the FM Towns Marty was released, a gaming console compatible with the FM Towns games.
Amdahl became a wholly owned subsidiary of Fujitsu in 1997.
The active partnership with Siemens AG was revived in 1999 in the form of Fujitsu Siemens Computers, now Europe's largest IT supplier, and owned 50/50 by Fujitsu and Siemens.
On March 2, 2004, Fujitsu Computer Products of America lost a class action lawsuit over hard disk drives with defective chips and firmware.
On April 1, 2006, Fujitsu Software Corporation merged with Fujitsu Computer Systems Corporation.
