(Students stood up)
Okay, sir.
Last meeting, we had discussed all about the tools in
computer hardware servicing.
Electro-Static Discharge, Hand Tools, Cleaning Tools and
diagnostic Tools.
We have Antistatic wrist strap and Antistatic Mat.
Sir, we have Flat Head screw driver, Philips head
screwdriver, Torx Screwdriver, Hex Driver, Needle-nose
plier, wire cutter, Tweezers, Part retriever and flashlight.
We have four tools for that sir, namely: Lint-free cloth,
Compressed air, Cable ties and parts organizer.
Yes sir, we have Multimeter and loopback adapter.
II. Activity
Before we will proceed to our formal discussion, kindly get ½

III. Analysis
Do you find the activity difficult?
Or are you able to answer it as easy as 1,2,3?
Mostly, if not, all of the given items tackle about the use of
tools in an appropriate way. I am just trying to check whether
you already have the knowledge in doing it so or in using the
tools in a proper way.
Definitely, yes.
(mixed answers)
Okay sir, so would that mean we are going to tackle the
proper use of tools today?
IV. Abstraction
Since, we already had identified the tools in the previous
lesson, today we will be focusing on the proper Use of Tools.
Let us have first, the ESD Tools.
So what do you think the purpose of antistatic wrist strap?
Very good. (the teacher will give further explanations)
The wrist strap has two parts and is easy to wear:
1. Wrap the strap around your wrist and secure it using the
snap or Velcro. The metal on the back of the wrist strap must
remain in contact with your skin at all times.
2. Snap the connector at the end of the wire to the wrist strap,
and connect the other end either to the equipment or to the
same grounding point that the antistatic mat is connected to.
The metal skeleton of the case is a good place to connect the
wire. When connecting the wire to equipment that you are
working on, choose an unpainted metal surface. A painted
surface does not conduct the electricity as well as unpainted
metal.
Now, how do we use Antistatic mat? Or how does it work?
Very good, let’s proceed to the proper Use of Hand Tools
Screws Match each screw with the proper screwdriver. Place
the tip of the screwdriver on the head of the screw. Turn the
The purpose of an antistatic wrist strap is to equalize the
electrical charge between you and the equipment. The
antistatic wrist strap is a conductor that connects your
body to the equipment that you are working on. When
static electricity builds up in your body, the connection
made by the wrist strap to the equipment, or ground,
channels the electricity through the wire that connects
the strap.
An antistatic mat is slightly conductive. It works by drawing
static electricity away from a component and transferring it
safely from equipment to a grounding point: 1. Lay the mat on
the workspace next to or under the computer case. 2. Clip the
mat to the case to provide a grounded surface on which you
can place parts as you remove them from the system.
Reducing the potential for ESD reduces the likelihood of
damage to delicate circuits or components.
screwdriver clockwise to tighten the screw and
counterclockwise to loosen the screw.
Screws can become stripped if you over-tighten them with a
screwdriver. A stripped screw may get stuck in the screw hole,
or it may not tighten firmly. Discard stripped screws.
Very good question. Use a flat head screwdriver when you are
working with a slotted screw. Do not use a flat head
screwdriver to remove a Phillips head screw. Never use a
screwdriver as a pry bar. If you cannot remove a component,
check to see if there is a clip or latch that is securing the
component in place.
Use a Phillips head screwdriver with crosshead screws. Do not
use this type of screwdriver to puncture anything. This will
damage the head of the screwdriver.
Now since you already have the knowledge of hex driver, so
what do you think the proper way of using it?
The part retriever, needle-nose pliers, and tweezers can be
used to place and retrieve parts that may be hard to reach with
your fingers. Do not scratch or hit any components when using
these tools.
Let’s proceed to the Proper Use of Cleaning Materials
Keeping computers clean inside and out is a vital part of a
maintenance program. Dirt can cause problems with the
physical operation of fans, buttons, and other mechanical
components. On electrical components, an excessive buildup of
dust will act like an insulator and trap the heat. This insulation
will impair the ability of heat sinks and cooling fans to keep
components cool, causing chips and circuits to overheat and
fail.
Computer Cases and Monitors
Clean computer cases and the outside of monitors with a mild
cleaning solution on a damp, lint-free cloth. Mix one drop of
dishwashing liquid with four ounces of water to create the
cleaning solution. If any water drips inside the case, allow
enough time for the liquid to dry before powering on the
computer.
LCD Screens
Do not use ammoniated glass cleaners or any other solution on
an LCD screen, unless the cleaner is specifically designed for the
purpose. Harsh chemicals will damage the coating on the
screen. There is no glass protecting these screens, so be gentle
when cleaning them and do not press firmly on the screen.
CRT Screens
To clean the screens of CRT monitors, dampen a soft, clean,
lint-free cloth with distilled water and wipe the screen from top
to bottom. Then use a soft, dry cloth to wipe the screen and
remove any streaking after you have cleaned the monitor.
Clean dusty components with a can of compressed air. Blow out
the dust using short bursts from the can. Never tip the can or
use the compressed air can upside down. Do not allow the fan
blades to spin from the force of the compressed air. Hold the
fan in place. Fan motors can be ruined from spinning when the
motor is not turned on.
Component Contacts
Clean the contacts on components with isopropyl alcohol. Do
not use rubbing alcohol. Rubbing alcohol contains impurities
that can damage contacts. Make sure that the contacts do not
collect any lint from the cloth or cotton swab. Blow any lint off
the contacts with compressed air before reinstallation.
Keyboard
So how do we use flat head screwdriver sir?
How about the Philips head screwdriver?
Use a hex driver to loosen and tighten bolts that have a
hexagonal (six-sided) head. Hex bolts should not be over-
tightened because the threads of the bolts can be stripped.
Do not use a hex driver that is too large for the bolt that
you are using. But how about the Part reliever, needle-
nose plier and tweezers? How to use it properly?
Clean a desktop keyboard with compressed air or a small, hand-
held vacuum cleaner with a brush attachment.
Mouse
Use glass cleaner and a soft cloth to clean the outside of the
mouse. Do not spray glass cleaner directly on the mouse. If
cleaning a ball mouse, you can remove the ball and clean it with
glass cleaner and a soft cloth. Wipe the rollers clean inside the
mouse with the same cloth. Do not spray any liquids inside the
mouse.
Thus, all of those things mentioned are the proper use of tools
in computer hardware servicing. Have you understood all of it?
Very Good. Let’s have a quiz now.
Yes, sir. It is very informative to the extent that we will
apply this whenever/if ever we are asked to have practical
application/ Hands-on Practice.
V. Application
Direction: Identify the appropriate tool to use for each of the
following statement below. Write it in a ½ crosswise.
_________________1. Equalize the electrical charge
between you and the equipment.
_________________2. Tighten / loosen screw
_________________3. Tighten / looses bold with a
hexagonal head
_________________4. Retrieve parts that may be hard to
reach by your fingers
_________________5. Tighten / loosen a slotted screw
Okay, sir.
VI. Assessment
WHAT TOOL TO USE? Direction: Use the appropriate tools to
do each of the following tasks.
1. Loosen computer casing screws
2. Blow away dust from keyboard
3. Tighten screws of a laptop
4. Bundle cables inside the computer
5. Test functionality of the printer port
Read the instruction carefully before answering each of the quiz
items.
Okay, sir copy.
VII. Assignment
Study today’s lesson and prepare for a short/follow-up quiz
tomorrow.
Okay sir, we will.

Introductory Activity Teacher’s Activity Students’ activity 1. Opening prayer I am requesting everybody to please stand for the prayer. Will you please lead… (point one student to lead the prayer) 2. Greetings Good Morning Class! Before we will start, kindly pick up all the trashes and throw it inside the trashcans/bins. 3. Energizer Everybody stand; let’s have an energizer to warm up your mind and body. 4. Checking of Attendance Let us check your attendance first, say present if your name is called. 5. Review Can anyone retell or recall what we had last meeting? (the teacher will do Random calling) Very Good. Then what are the four categories of tools? What are the tools in Electro-Static Discharge? How about for hand tools? Very good, how about for the cleaning tools? And lastly, could you still remember the tools in Diagnosing computer damages/Malfunctions? Let us put ourselves in the holy presence of God. In the name of the Father, the Son, and the Holy Spirit. Amen The Lord’s prayer. Good Morning Sir. (students will start picking up the pieces of paper and plastic) (Students stood up) Okay, sir. Last meeting, we had discussed all about the tools in computer hardware servicing. Electro-Static Discharge, Hand Tools, Cleaning Tools and diagnostic Tools. We have Antistatic wrist strap and Antistatic Mat. Sir, we have Flat Head screw driver, Philips head screwdriver, Torx Screwdriver, Hex Driver, Needle-nose plier, wire cutter, Tweezers, Part retriever and flashlight. We have four tools for that sir, namely: Lint-free cloth, Compressed air, Cable ties and parts organizer. Yes sir, we have Multimeter and loopback adapter. II. Activity Before we will proceed to our formal discussion, kindly get ½ sheet of paper for today’s activity. Direction. Fill in the blanks. 1. The purpose of an antistatic wrist strap is to ________ the electrical charge between you and the equipment. 2. Turn the screwdriver _________ to tighten the screw 3. Turn the screwdriver ________________ to loosen the screw. 4. Use a ________ head screwdriver with crosshead screws. 5. On electrical components, an excessive buildup of dust will act like an _________ and trap the heat. Okay sir.
  • 2. 6. When compressed air is used to clean inside the computer, the air should be blown around the components with a minimum distance of ______ inches from the nozzle. 7. Pencils should not be used inside the computer to change the setting of switches or to pry off jumpers because the tip contains _____ which can act as a conductor and may damage the computer components. 8. To clean the screens of CRT monitors, dampen a soft, clean, lint-free cloth with _______ water and wipe the screen from top to bottom. 9. Clean the contacts on components with _________ alcohol. 10. Use a __________ to loosen and tighten bolts that have a hexagonal (six-sided) head. III. Analysis Do you find the activity difficult? Or are you able to answer it as easy as 1,2,3? Mostly, if not, all of the given items tackle about the use of tools in an appropriate way. I am just trying to check whether you already have the knowledge in doing it so or in using the tools in a proper way. Definitely, yes. (mixed answers) Okay sir, so would that mean we are going to tackle the proper use of tools today? IV. Abstraction Since, we already had identified the tools in the previous lesson, today we will be focusing on the proper Use of Tools. Let us have first, the ESD Tools. So what do you think the purpose of antistatic wrist strap? Very good. (the teacher will give further explanations) The wrist strap has two parts and is easy to wear: 1. Wrap the strap around your wrist and secure it using the snap or Velcro. The metal on the back of the wrist strap must remain in contact with your skin at all times. 2. Snap the connector at the end of the wire to the wrist strap, and connect the other end either to the equipment or to the same grounding point that the antistatic mat is connected to. The metal skeleton of the case is a good place to connect the wire. When connecting the wire to equipment that you are working on, choose an unpainted metal surface. A painted surface does not conduct the electricity as well as unpainted metal. Now, how do we use Antistatic mat? Or how does it work? Very good, let’s proceed to the proper Use of Hand Tools Screws Match each screw with the proper screwdriver. Place the tip of the screwdriver on the head of the screw. Turn the The purpose of an antistatic wrist strap is to equalize the electrical charge between you and the equipment. The antistatic wrist strap is a conductor that connects your body to the equipment that you are working on. When static electricity builds up in your body, the connection made by the wrist strap to the equipment, or ground, channels the electricity through the wire that connects the strap. An antistatic mat is slightly conductive. It works by drawing static electricity away from a component and transferring it safely from equipment to a grounding point: 1. Lay the mat on the workspace next to or under the computer case. 2. Clip the mat to the case to provide a grounded surface on which you can place parts as you remove them from the system. Reducing the potential for ESD reduces the likelihood of damage to delicate circuits or components.
  • 3. screwdriver clockwise to tighten the screw and counterclockwise to loosen the screw. Screws can become stripped if you over-tighten them with a screwdriver. A stripped screw may get stuck in the screw hole, or it may not tighten firmly. Discard stripped screws. Very good question. Use a flat head screwdriver when you are working with a slotted screw. Do not use a flat head screwdriver to remove a Phillips head screw. Never use a screwdriver as a pry bar. If you cannot remove a component, check to see if there is a clip or latch that is securing the component in place. Use a Phillips head screwdriver with crosshead screws. Do not use this type of screwdriver to puncture anything. This will damage the head of the screwdriver. Now since you already have the knowledge of hex driver, so what do you think the proper way of using it? The part retriever, needle-nose pliers, and tweezers can be used to place and retrieve parts that may be hard to reach with your fingers. Do not scratch or hit any components when using these tools. Let’s proceed to the Proper Use of Cleaning Materials Keeping computers clean inside and out is a vital part of a maintenance program. Dirt can cause problems with the physical operation of fans, buttons, and other mechanical components. On electrical components, an excessive buildup of dust will act like an insulator and trap the heat. This insulation will impair the ability of heat sinks and cooling fans to keep components cool, causing chips and circuits to overheat and fail. Computer Cases and Monitors Clean computer cases and the outside of monitors with a mild cleaning solution on a damp, lint-free cloth. Mix one drop of dishwashing liquid with four ounces of water to create the cleaning solution. If any water drips inside the case, allow enough time for the liquid to dry before powering on the computer. LCD Screens Do not use ammoniated glass cleaners or any other solution on an LCD screen, unless the cleaner is specifically designed for the purpose. Harsh chemicals will damage the coating on the screen. There is no glass protecting these screens, so be gentle when cleaning them and do not press firmly on the screen. CRT Screens To clean the screens of CRT monitors, dampen a soft, clean, lint-free cloth with distilled water and wipe the screen from top to bottom. Then use a soft, dry cloth to wipe the screen and remove any streaking after you have cleaned the monitor. Clean dusty components with a can of compressed air. Blow out the dust using short bursts from the can. Never tip the can or use the compressed air can upside down. Do not allow the fan blades to spin from the force of the compressed air. Hold the fan in place. Fan motors can be ruined from spinning when the motor is not turned on. Component Contacts Clean the contacts on components with isopropyl alcohol. Do not use rubbing alcohol. Rubbing alcohol contains impurities that can damage contacts. Make sure that the contacts do not collect any lint from the cloth or cotton swab. Blow any lint off the contacts with compressed air before reinstallation. Keyboard So how do we use flat head screwdriver sir? How about the Philips head screwdriver? Use a hex driver to loosen and tighten bolts that have a hexagonal (six-sided) head. Hex bolts should not be over- tightened because the threads of the bolts can be stripped. Do not use a hex driver that is too large for the bolt that you are using. But how about the Part reliever, needle- nose plier and tweezers? How to use it properly?
  • 4. Clean a desktop keyboard with compressed air or a small, hand- held vacuum cleaner with a brush attachment. Mouse Use glass cleaner and a soft cloth to clean the outside of the mouse. Do not spray glass cleaner directly on the mouse. If cleaning a ball mouse, you can remove the ball and clean it with glass cleaner and a soft cloth. Wipe the rollers clean inside the mouse with the same cloth. Do not spray any liquids inside the mouse. Thus, all of those things mentioned are the proper use of tools in computer hardware servicing. Have you understood all of it? Very Good. Let’s have a quiz now. Yes, sir. It is very informative to the extent that we will apply this whenever/if ever we are asked to have practical application/ Hands-on Practice. V. Application Direction: Identify the appropriate tool to use for each of the following statement below. Write it in a ½ crosswise. _________________1. Equalize the electrical charge between you and the equipment. _________________2. Tighten / loosen screw _________________3. Tighten / looses bold with a hexagonal head _________________4. Retrieve parts that may be hard to reach by your fingers _________________5. Tighten / loosen a slotted screw Okay, sir. VI. Assessment WHAT TOOL TO USE? Direction: Use the appropriate tools to do each of the following tasks. 1. Loosen computer casing screws 2. Blow away dust from keyboard 3. Tighten screws of a laptop 4. Bundle cables inside the computer 5. Test functionality of the printer port Read the instruction carefully before answering each of the quiz items. Okay, sir copy. VII. Assignment Study today’s lesson and prepare for a short/follow-up quiz tomorrow. Okay sir, we will. Remarks: Prepared by: Checked By: DIONESIO O. CABUYAO JR. MRS. ROXANE C.
