In computing, a keyboard is a typewriter-style device, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboards became the main input device for computers. Keyboards typically have characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol. However, to produce some symbols requires pressing and holding several keys simultaneously or in sequence. While most keyboard keys produce letters, numbers or signs (characters), other keys or simultaneous key presses can produce actions or computer commands. Despite the development of alternative input devices, such as the mouse, touchscreen, pen devices, character recognition and voice recognition, the keyboard remains the most commonly used and most versatile device used for direct (human) input into computers.
In 99% of laptops the keyboard is the largest input device present. It covers the top of the inside cover, and can be removed as a whole. That being said the keyboard is not truly attached to the laptop and dust, debris, or food can get into and under the keyboard itself. This causes your keys to become “sticky” and sometimes unresponsive. Also this could lead to potential computer damage, depending on what may fall in between the keyboard cracks.
If food or debris get lodged between your the keys and the keyboard, this can produce non-functioning keystrokes. Liquid damage would have the same effect, but also producing a “sticky” feel if the liquid contains sugar. Individual keys can get broken off or removed over time and need to be replaced. Some of the errors you could see if your keyboard needs to be replaced are:
- Missing Keys
- Stuck or Sticky keys
- Keyboard not accepting input
- Keyboard displaying the wrong keystroke, A=F etc.
