2: Disassembly
Overview
This chapter provides step-by-step instructions for disassembling parts and subsystems. When it comes to reassembly,
reverse the procedures (unless otherwise indicated).
We suggest you completely review any procedure before you take the computer apart.
Procedures such as upgrading/replacing the RAM, CD device and hard disk are included in the Us er’s Manual but are
repeated here for your convenience.
To make the disassembly process easier each section may have a box in the page margin. Information conta ined under
the figure # will give a synopsis of the sequence of procedures involved in the disassembly procedure. A box with a
lists the relevant parts you will have after the disassembly process is complete. Note: The parts listed will be for the disassembly procedure listed ONLY, and not any previous disassembly step(s) required. Refer to the part list for the previous disassembly procedure. The amount of screws you should be left with will be listed here also.
A box with a
5 will provide any possible helpful information. A box with a contains warnings.
Examples of these types of boxes are shown in the sidebar.

2 - 2 Overview
2.Disassembly
NOTE: ALL DISASSEMBLY PROCEDURES ASSUME THAT THE SYSTEM IS TURNED OFF, DISCONNECTED FROM ANY POWER SUPPLY, AND THAT ALLL PERIPHERAL CABLES ARE DISCONNECTED (INCLUDING TELEPHONE LINES AND NETWORK CABLES).
Maintenance Tools
The following tools are recommended when working on the notebook PC:
• M3 Philips-head screwdriver
• M2.5 Philips-head screwdriver (magnetized)*
• M2 Philips-head screwdriver
• Small flat-hea d scre wd ri ver
• Pair of needle-nose pliers
• Anti-static wrist-str ap
Connections
Connections within the computer are one of four types:
Locking collar sockets for ribbon connectors To release these connectors, use a small flat-hea d screwdriver to
gently pry the locking collar away from its base. When replacing the connection, make sure the connector is oriented in the
same way. The pin1 side is usually not indicated.
Pressure sockets for multi-wire connectors To release this connector type, grasp it at its head and gently
rock it from side to side as you pull it out. Do not pull on the
wires themselves. When replacing the connection, do not try to
force it. The socket only fits one way.
Pressure sockets for ribbon connectors To release these connectors, use a small pair of needle-nose pli-
ers to gently lift the connector away from its socket. When replacing the connection, make sure the connector is oriented in
the same way. The pin1 side is usually not indicated.
Board-to-board or multi-pin sockets To separate the boards, gently rock them from side to side as
you pull them apart. If the connection is very tight, use a small
flat-head screwdriver - use just enough force to start.

Maintenance Precautions
The following precautions are a reminder. To avoid personal i njury or damage to the c omputer while performing a removal and/or replacement job, take the following precautions:
1. Don't drop it. Perfo rm y our repairs and/or upgrades on a stable surface. If th e c om puter falls, the ca s e and other
components could be damaged.
2. Don't overheat it. Note the proximity of an y heating elements. Keep the comp ut er out of direct su nlight.
3. Avoid interference. Note the proximity of any high capacity tra ns f ormers, elect ric m ot ors, and other st rong magnetic fields. Th es e c an hinder proper performanc e and damage co mponents and/or data. You should also monitor
the position of ma gnetized tools (i. e. screwdrivers).
4. Keep it dry. This is an electrical appliance. If water or any other liquid gets into it, the computer could be badly damaged.
5. Be care fu l wi th p o wer. Avoid accidental shocks, discharges or explosions.
• Before removing or servicing any part from the computer, turn the computer of f and detach any power supplies.
• When you want to unplug the power cord or any cable/wire, be sure to disconnect it by the plug head. Do not pull on the
wire.
6. Peripherals – Turn off and detach any peripherals.
7. Beware of static discharge. ICs, such as the CPU and main support chips, are vulnerable to static ele c tr ic it y.
Before handling any part in the computer, discharge any stat ic electricity inside the computer. When handling a
printed circuit board, do not use gloves or other materials which allow static electricity buildup. We suggest that you
use an anti-static w ris t strap instead.
8. Beware of corrosion. As you perform y our job, avoid tou c hing any connec t or leads. Even the cleanest hands produce oils which c an attract corrosiv e elements.
9. Keep your wor k environment clean . Tobacco smoke, dust or other air-born particulate matter is often attracted to
charged surfac es, reducing performance.
10.Keep track of the components. When removing or replacing any part, be careful not to leave small parts, such as
screws, loose inside the computer.
Cleaning
Do not apply cleaner directly to the computer, use a soft clean cloth.
Do not use volatile (petroleum distillates) or abrasive cleaners on any part of the computer.
