2.1 Before y ou b egin
Ensure you have a stable, clean working environment. Dust and dirt can get into components
and cause a malfunction. Use containers to keep small components separated.
Adequate lighting and proper tools can prevent you from accidentally damaging the internal
components. Most of the procedures that follow require only a few simple tools, including the
following:
• A Philips screwdriver • A flat-tipped screwdriver
• A set of jewelers Screwdrivers • A grounding strap
• An anti-static pad
Using your fingers can disconnect most of the connections. It is recommended that you do not
use needle-nosed pliers to disconnect connections as these can damage the soft metal or
plastic parts of the connectors.
Before working on internal components, make sure that the power is off. Ground yourself
before touching any internal components, by touching a metal object. Static electricity can
damage many of the electronic components. Humid environment tend to have less static
electricity than dry environments. A grounding strap is warranted whenever danger of static
electricity exists.
2.2 Precautions
Computer components and electronic circuit boards can be damaged by discharges of static
electricity.
Working on the computers that are still connected to a power supply can be extremely
dangerous. Follow the guidelines below to avoid damage to your computer or yourself:
• Always disconnect the unit from the power outlet whenever you are working inside the case.
• If possible, wear a grounded wrist strap when you are working inside the computer case.
Alternatively, discharge any static electricity by touching the bare metal chassis of the unit
case, or the bare metal body of any other grounded appliance.
• Hold electronic circuit boards by the edges only. Do not touch the components on the board
unless it is necessary to do so. Don’t flex or stress the circuit board.
