Vacuuming the computer, cleaning CD/DVD laser, and using urethane swabs to clean between the keys on a keyboard are all common tasks performed during preventive maintenance. Cleaning the CPU's gold pins, lubricating disassembled drives, and replacing cables are more advanced maintenance tasks. Using alcohol to clean the case, moving adapters to different locations on the motherboard, and pressing the power-on and off button 10 times in quick succession are not standard practices during preventive maintenance. Replacing the computer case, upgrading the microprocessor, and using soap and water to clean printer rollers are all major hardware changes and not part of routine preventive maintenance.
