COMPUTER HARDWARE SERVICING; TESDA COMPETENCIES
This is an online lecture in Computer Hardware Servicing, prepared by Mr. George P. Lumayag, ICT Coordinator. These Skills Learning Competencies are patterned from TESDA in preparation of the K to 12 implementation.
Electro-Static Discharge (ESD) Tools
Static electricity is easily generated by friction on carpets, tile flooring, clothing, hair, fabric, and etc. The friction of moving air alone will charge suspended parties and cause the buildup of static electrical charges on people and objects in the environment. Grounded antistatic work mats used electrostatic electricity. Examples of ESD Tools:
Anti-static wrist strap
Anti-static wrist strap-used to prevent ESD damage to computer equipment.
Anti-static mat
Anti-static - used to stand on or place hardware on to prevent static electricity from building up.
Hand Tools
A hand tool is a device for performing work on a material or a physical system using only hands. The hands tools can be manually used employing force, or electrically powered, using electrical current. Examples of Hand Tools:
Flat head screwdriver
Flat head screwdriver - used to loosen or tighten slotted screws.
Philips head screwdriver
Philips head screwdriver - used to loosen or tighten cross-head screws.
Torx screwdriver
Torx screwdriver - used to loosen or tighten screws that have a star-like depression on the top, a feature that is mainly found laptop.
Hex driver
Hex driver - sometimes called a nut driver, is used to tighten nuts in the same way that a screwdriver tightens screws.
Needle-nose plier
Needle-nose plier - used to hold small parts.
Wire cutter
Wire cutter - used to strip and cut wires.
Tweezers
Tweezers - used to manipulate small parts.
Part retriever
Part retriever - used to retrieve parts from location that are to small for your hand to fit.
Flashlight
Flashlight - used to light up areas that you cannot see well.
Cleaning Tools
Having the appropriate cleaning tools is essential when maintaining or repairing computers. Using these tools ensures the computer components are not damage during cleaning. Examples.
Lint-free cloth
Lint-free cloth - used to clean different computer components without scratching or leaving debris.
Compressed air
Compressed air - used to blow away dust and debris from different computer parts without touching the components.
Cable ties
Cable ties - used to bundle cables neatly inside and outside of a computer.
Parts organizer
Parts organized - used to hold screw, jumpers, fasteners and other small parts and prevents them from getting mixed together.
Diagnostic Tools
Computers are easier to use and more dependable with each new generation of hardware and operating system update, but that doesn't mean they're problem-free. Here's the most popularb tools for diagnosing your computer problems:
Multimeter
Multimeter -used to test the integrity of circuits and the quality of electricity in computer components.
Loopback Adapter
Loopback Adapter - used to test the functionality of computer ports.
PC Tools for Software and Hardware Trouble Shooting.
These are the PC Tools and Components that will be used in PC Hardware and Software Trouble Shootings.
A lens 
A lens is an optical device which transmits and refracts light, converging or diverging the beam.[
