Computer maintenance

The crumbs, dust, and other particulate that fall between the keys and build up underneath are loosened by spraying pressurized air into the keyboard, then removed with a low-pressure vacuum cleaner.

A plastic-cleaning agent applied to the surface of the keys with a cloth is used to remove the accumulation of oil and dirt from repeated contact with a user's fingertips.

If this is not sufficient for a more severely dirty keyboard, keys are physically removed for more focused individual cleaning, or for better access to the area beneath.

The top surface of the mouse is wiped with a plastic cleanser to remove the dirt that accumulates from contact with the hand, as on the keyboard.

When major maintenance such as patching is performed, a backup is recommended as the first step in case the update fails and reversion is required.

They also introduce new features and capabilities, ensuring that the software remains compatible with evolving technological standards and user needs.
