Disassembly
Chapter 2: Disassembly
Overview
This chapter provides step-by-step instructions for disassembling the L390T series LCD computer’s 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, optical device and hard disk are included in the User’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 contained 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 will also provide any possible helpful information. A box with a contains warnings.

An example of these types of boxes are shown in the sidebar.
Overview 2 - 1
Disassembly
2.Disassembly
NOTE: All disassembly procedures assume that the system is turned OFF, and disconnected from any power supply (the
battery is removed too).
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-head screwdriver
• Pair of needle-nose pliers
• Anti-static wrist-strap
Connections
Connections within the computer are one of four types:
Locking collar sockets for ribbon connectors To release these connectors, use a small flat-head 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.
2 - 2 Overview
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 pliers 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

Maintenance Precautions
The following precautions are a reminder. To avoid personal injury or damage to the computer while performing a removal and/or replacement job, take the following precautions:
1. Don't drop it. Perform your repairs and/or upgrades on a stable surface. If the computer falls, the case and other
components could be damaged.
2. Don't overheat it. Note the proximity of any heating elements. Keep the computer out of direct sunlight.
3. Avoid interference. Note the proximity of any high capacity transformers, electric motors, and other strong mag-
netic fields. These can hinder proper performance and damage components and/or data. You should also monitor
the position of magnetized 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 careful with power. Avoid accidental shocks, discharges or explosions.
•Before removing or servicing any part from the computer, turn the computer off 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 pu ll on the wir e.
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 electricity.
Before handling any part in the computer, discharge any static 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 wrist strap instead.
8. Beware of corrosion. As you perform your job, avoid touching any connector leads. Even the cleanest hands produce oils which can attract corrosive elements.
9. Keep your work environment clean. Tobacco smoke, dust or other air-born particulate matter is often attracted
to charged surfaces, reducing performance.
10. Keep track of the component s. When removing or re placing any part, be careful not to leave small p arts, such as
screws, loose inside the computer.
