Transcript of Computer Hardware Servicing: Hand Tools

Assigned Task:

Have an advanced reading about Occupational Safety and Health Use the appropriate tools to do each of the following tasks. Safety precautions must be observed while working.
 
1. Loosen computer casing screws.
2. Blow away dust from keyboard.
3. Tighten screws of a PC.
4. Bundle cables inside the computer.
5. Test functionality of the printer port. 1. Watch the video presentations on youtube using the following URL:
 
http://www.youtube.com/watch?v=s7M6_VeDhJE&feature=related
 

2. After watching the presentation, you must answer the following questions:

a. What is your observation on the video being presented to you?
b. What are the tools you are familiar with?
c. Do you think those tools are essential in computer hardware servicing? Explain your answer. Using the different available tools in the following, you will segregate the tools according to their classification whether it is an ESD tool, Hand tool, Cleaning tool or a Diagnostic tool. Proper Use of Cleaning Materials
 
1. To clean computers and accessories:
2. Use mild cleaning solution and lint-free cloth to clean computer cases, outside of monitor, LCD screen, CRT screen and mouse.
3. Use compressed air to clean heat sinks.
4. Use Isopropyl alcohol and lint-free swabs to clean RAM.
5. Use hand-held vacuum cleaner with a brush attachment to clean a keyboard. Proper Use of Hand Tools

1. Use the proper type and size of screwdriver by matching it to the screw.

2. Do not over tighten screws because the threads may become stripped.  
Proper Use of Antistatic Mat

1. Lay the computer on the mat.
2. Connect the computer to the mat with the cable.
3. Connect the mat to a reliable electrical ground with its cable.
4. Now, you and the computer are at ground potential. Proper Use of ESD Tools
Proper Use of Antistatic Wrist Strap

1. Connect the cable to the metal chassis of the computer.
2. Wrap the strap around your wrist.
3. The connection will keep your body at the same voltage (potential) as the computer.
4. Attach the wire on the same side of the equipment as the arm wearing the antistatic wrist strap to keep the wire out of the way while you are working. LOOPBACK ADAPTER – Used to test the functionality of computer ports. MULTIMETER – Used to test the integrity of circuits and the quality of electricity in computer components. DIAGNOSTIC TOOLS
 
Computers are easier to use and more dependable with each new generation of hardware and operating system update, but that does not mean they are problem-free. PARTS ORGANIZER – Used to hold screw, jumpers, fasteners and other small parts and prevents them from getting mixed together. CABLE TIES – Used to bundle cables neatly inside and outside of a computer. COMPRESSED AIR – Used to blow away dust and debris from different computer parts without touching the components. LINT-FREE CLOTH – Used to clean different computer components without scratching or leaving debris. CLEANING TOOLS

Having the appropriate cleaning tools is essential when maintaining or repairing computers. Using these tools ensures that computer components are not damaged during cleaning. FLASHLIGHT – Used to light up areas that you cannot see well. PART RETRIEVER – Used to retrieve parts from location that is too small for your hand to fit. TWEEZERS – Used to manipulate small parts. WIRE CUTTER – Used to strip and cut wires. NEEDLE-NOSE PLIERS – Used to hold small parts. HEX DRIVER – Sometimes called a nut driver, is used to tighten nuts in the same way that a screwdriver tightens screws. PHILIPS HEAD SCREWDRIVER – Used to loosen or tighten cross-head screws. FLAT HEAD SCREWDRIVER – Used to loosen or tighten slotted screws. HAND TOOLS
 
A hand tool is a device for performing work on a material or a physical system using only hands. Hand tools can be used manually or electrically powered, using electrical current. ANTI-STATIC MAT – Used to stand on or place hardware on to prevent static electricity from building up.





  ANTI-STATIC WRIST STRAP – Used to prevent ESD damage to computer equipment.




  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 particles and cause the buildup of static electrical charges on people and objects in the environment. Grounded antistatic work mats used with antistatic wrist straps provide the most basic means for the controlled discharge of electrostatic electricity. Electro-Static Discharge (ESD) Tools
Hand Tools
Cleaning Tools
Diagnostic Tools HARDWARE TOOLS 4. Tools to be operated according to manufacturer’s instructions

5. the right protective equipment for the tool and activity be used. 1. All tools be kept in good condition with regular maintenance.

2. The right tool be used for the job

3. Each tool be examined before used and damaged or defective tools not to be used Environmental Safety and Health Program requires the following: Once selected, use the tool for the purpose for which it was designed. SAFE USE OF TOOLS When obtaining the tool all the associated tooling and consumable parts, as recommended by the manufacturer, must be included. Selecting the best tool for each task requires training in the proper use of the tools, field experience in their safe use, and following the manufacturer’s guidance and instructions for that specific tool. Know and understand in detail the scope of work to be accomplished


Plan for the scope taking into account the sequence of tasks. How do you select the best tool for the job??? PREPARING FOR THE TASK TO BE UNDERTAKEN INCLUDES PROPER TOOL SELECTION A tool is handheld device that aids in accomplishing task. Tools range from a traditional metal cutting part of machine to an element of a computer program that activates and controls a particular function. PROPER TOOL SELECTION 10.
