Overview

This chapter provides step-by-step instructions for disassembling the M400A/M400G/M40AE/M40GE series notebook’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.

Disassembly

Procedures such as upgrading/replacing the RAM, CD 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.

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.

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 just enough force to start.

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 components. When removing or replacing any part, be careful not to leave small part s, such as screws, loose inside the computer.
