TOOLS NEEDED BY A COMPUTER TECHNICIAN.

Chapter 1
Basic tools used by a Laptop Technician
“discussion of both hand and power tools used”
Here I will list the tools common name, then, I will give a brief description of that tool’s
usages relating to Laptop repairing. Please note: Being that this is a DIY book, I will omit the
tools that the
average person can not obtain or tools that would be out of price range for most individuals.

1.   Head Screwdriver  

This is the
average sized screwdriver, as that would be too large for the tiny screws used on laptops today.
This is the micro-sized screwdriver, which can be bought at your local Home Improvement store.

2.DIGITAL MULTI METER.

This can be bought at your local Home
Improvement store, and you will find a wide variety of quality choices. For a beginner, it is ok to
purchase the cheapest Multi-meter to learn its uses and familiarize yourself with it.

• It is use for the testing of
• capacitor
• transistor
• electrical voltage

3.SOLDER WIRE OR LEAD WIRE.

The average Rosin Core Solder will do, get your self 1.0mm solder, any thicker and it will apply to heavily on a joint of two point.

It is use on….

• The motherboard.

It is use to connect to point on the motherboard like wires.

4.  SOLDERING IRON.

You can use any
brand of these and they are typically disposable. I recommend that you do dispose of the cheaper
soldering irons after 10 or so uses, or get yourself some Tinner to refresh the tip. I do recommend a
50 watt iron for laptop component repair as it will allow for better ―flowǁ of the solder due to the
higher temperature output

It is use for working on the motherboard.

• it work with solder wire.

5.Circuit Board Cleaning Solution.

This solvent is used to clean the motherboard, and I will clarify its uses throughout this book. WD40 is
more readily available to purchase and can suffice. Again, I will also explain how to properly use
WD40 to clean components/remove flux and so forth.

• it is use for
• cleaning of the mother board.
• you can still use your methylated spirit to do that to.
• MAKE SURE IT GET DRY BEFORE WORKING ON THE MOTHERBOARD. (NOTE).
• OR MAKE USE OF YOUR HEAT GUN IT LOOK LIKE THIS.
• HEAT GUN

6.Mini Pliers.

I suggest that you buy mini needle nosed
pliers because they are easier to use on the micro sized components that make up the laptop. The
pliers I use are 3 inches long, I find that the normal sized pliers are way too big and do not reach into
certain areas that the mini can.

IT IS USE TO

• REMOVE HOT TRANSISTOR,
• IT IS USE FOR JOINING OF WIRE OR PULL OUT COMPONENT ON THE MOTHERBOARD.

7.BRUSH

I suggest that you buy mini needle nosed
pliers because they are easier to use on the micro sized components that make up the laptop. The
pliers I use are 3 inches long, I find that the normal sized pliers are way too big and do not reach into
certain areas that the mini can.

• IT IS USE
• TO CLEAN THE MOTHERBOARD IF DUSTY.

8.Electrical Tape.

This is used to wrap cables and
wires, and used to secure or flatten wire or cable tracks on or in the laptop. I try not to use this on
wire or cable wrapping if possible because I have found that over time the tape will slowly unravel
and can become ―stickyǁ on the outer-side.

• IT IS USE
• TO TAPE A ELECTROCUTE PLACE ON THE MOTHERBOARD.
