You work for a small city IT department and you are training

You work for a small city IT department, and you are training a new technician in computer maintenance procedures. What devices do you say are safe to operate inside a computer?

A. A can of compressed air

B. Air from an air compressor

C. A magnetic probe

D. An ordinary home vacuum cleaner

Solution

A and C. A can of compressed air is commonly used to blow out dust and debris in a computer case. Make sure you are working in an area where the dust won’t contaminate other objects or make a general mess. You can use a specialized magnetic device to lift out loose screws or other small metal objects from a computer’s interior that are too difficult to grip by hand. Also, this tool is safer to use than putting your hand in the case, since you are less likely to accidentally damage some component.
