Disassembly

and Power

Many technicians do not go on a repair call with a full tool case. Ninety-five percent of all

repairs are completed with the following basic tools:

• Small and medium flat-tipped screwdrivers

• #0, #1, and #2 Phillips screwdrivers

• 1/4- and 3/16-inch hex nut drivers

• Small diagonal cutters

• Needlenose pliers

Screwdrivers take care of most disassemblies and

reassemblies. Sometimes manufacturers place tie

wraps on new parts, new cables, or the cables inside

the computer case. The diagonal cutters are great

for removing the tie wraps without cutting cables

or damaging parts. Needlenose pliers are good for

straightening bent pins on cables or connectors, and

doing a million other things. Small tweaker screw-

drivers and needlenose pliers are indispensable.

Many technicians start with a basic $15 micro-

computer repair kit and build from there. A bargain

table 6-in-1 or 4-in-1 combination screwdriver that

has two sizes of flat-tipped and two sizes of Phillips screwdrivers is a common tool among new

technicians. A specialized Swiss army knife with screwdrivers is the favorite of some technicians.

Other technicians prefer to carry an all-in-one tool in a pouch that connects to their belt.

Alternatives to the magnetic screwdriver include a screw pick-up tool and common sense.

A screw pick-up tool is used in hard-to-reach places and sometimes under the motherboard. If

a screw rolls under the motherboard and cannot be reached, tilt the computer so that the screw

rolls out. Sometimes the case must be tilted in different directions until the screw becomes dis-

lodged.

There are tools that no one thinks of as tools but that should be taken on a service call every

time. They include a pen or pencil with which to take notes and fill out the repair slip and a

bootable disc containing the technician’s favorite repair utilities. Usually a technician has several

bootable discs for different operating systems and utilities. Often a flashlight comes in handy

because some rooms and offices are dimly lit. Finally, do not forget to bring a smile and a sense

of humor.

Tools that are nice to have but not used daily include the following:

• Multimeter

• Screw pick-up tool

• Screwdriver extension tool

• Soldering iron, solder, and flux

• Screw-starter tool

• Medium-size diagonal cutters

• Metric nut drivers

• Cable-making tools

• Cable tester

• Loopback plug

• Punch down tool

• Toner probe

• Wire stripper

• Crimper

Do not use magnetized screwdrivers

Avoid using a magnetic screwdriver when working

on a computer. It can cause permanent loss of

data on hard drives or floppy disks. Magnetism can

also induce currents into components and damage

them. Sometimes, technicians are tempted to use a

magnetic screwdriver when they drop a small part

such as a screw into a hard-to-reach place, but

avoid using a magnetic screwdriver.
