The laptop keyboard generally has a scissor key mechanism. Laptop keyboards have a scissor-type mechanism to maximize the amount of distance inverted dome switches can travel without making contact with other keys, unlike a standard desktop keyboard where each switch sits in a rectangle that could collide with adjacent buttons when it is pressed downwards.
The electronic circuits in the laptop motherboard update sixteen times per second and may send audio or video files to an attached monitor, hard disk drive, DVD player, or TV set. The processor (which typically exceeds one gigahertz) controls such operations as booting up for use and playing multimedia content if requested by the user.
