Keeping your Computer Clean

Cleaning the keyboard

Dust, food, liquid, and other particles can get stuck underneath the keys on your keyboard, which can prevent it from working properly. The basic cleaning tips below can help keep your keyboard clean.

1. Unplug the keyboard from the USB or PS/2 port. If the keyboard is plugged into the PS/2 port, you will need to shut down the computer before unplugging it.
2. Turn the keyboard upside down and gently shake it to remove dirt and dust.
3. Use a can of compressed air to clean between the keys.

Cleaning the mouse
There are two main mouse types: optical and mechanical. Each is cleaned in basically the same way, although the mechanical mouse requires a bit more work.

1. Optical mice require no internal cleaning because they do not contain any rotating parts; however, they can get sticky over time as dust collects near the light emitter. This can cause erratic cursor movement or prevent the mouse from working properly.
2. Mechanical mice are especially susceptible to dust and particles that can accumulate inside the mouse, which can make it difficult to track—or move—properly. If the mouse pointer does not move smoothly, the mouse may need to be cleaned.
