Computer repair technicians fix and maintain computers for corporations and individual clients. Because modern electronic components, including those in computers, are usually non-repairable modules, you will seldom do more than replace computer modules. However, as easy as this is, you still need specific skills, such as being able to:

1. Troubleshoot a problem to identify its defective module.
2. Disassemble the computer to where you can access that module.
3. Replace the module while wearing a grounding wrist strap to guard against static-electricity damage.
4. Reassemble the computer.
5. Test the computer to ensure that the new module is functioning correctly.
