How laptops are made

A 1981 Epson with an LCD, a battery and a built-in printer was already being called a laptop.

The short version

A laptop is assembled in a metal or plastic clamshell. The motherboard, memory and storage are fixed into the lower half, where most of the hardware lives. A keyboard and trackpad go on top, a lithium-ion battery fills much of the underside, and a hinged lid carries the flat-panel screen.

  1. Mold or machine the case

    The lower and upper halves of the case are molded in plastic or machined from metal.

  2. Install keyboard and trackpad

    A thin keyboard, usually with scissor switches, and a trackpad go in the top of the base.

  3. Hinge on the display

    The flat-panel screen, usually 11 to 17 inches diagonally, goes in the lid with a webcam above it.

  4. Load and burn in

    Software is installed and the machine is run for hours to find early failures before shipping.

Worth repeating

  • Seiko Epson showed an early machine called a laptop in 1981 with an LCD screen, a rechargeable battery and a built-in printer, weighing 1.6 kg.
  • Laptop keyboards more often use scissor switches than the rubber domes common on full-size keyboards.
  • Most of a laptop's hardware sits in the lower half under the keyboard, and the lid holds little besides the screen.
