Information
Warning
Vinafix.com
Overview
This chapter provides step-by-step instructions for disassembling the NH50DB / NH50DE / NH57DB / NH57DE 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, 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.

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-st atic wris t-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 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
Power Safety
Warning
Before you undertake
any upgrade procedures, make sure that
you have turned off the
power, and disconnected all peripherals
and cables (including

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 st able surface. If the computer falls, the case and other compo nents
could be damaged.
2. Don't overheat it. Note the proximity of any heating elements. Keep the compute r out of direct sunlight.
3. Avoid interference. Note the proximity of any high capacity transformers, electric motors, and other strong magnetic 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 compu te r, 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 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 electricity. Before handling any part in the computer, discharge any static electricity inside the computer. When handling a pr inted 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 of ten attracted to charged
surfaces, 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.
(For Computer Models Supplied with Light Blue Cleaning Cloth) Some computer models in this series come supplied with a
light blue cleaning cloth. To clean the computer case with this cloth follow the instructions below.
• Power off the computer and peripherals.
• Disconnect the AC/DC adapter from the computer.
• Use a little water to dampen the cloth slightly.
• Clean the computer case with the cloth.
• Dry the computer with a dry cloth, or allow it time to dry before turning on.
• Reconnect the AC/DC adapter and turn the computer on.
