Safety Precautions
Before you begin disassembly, read the following safety precautions and observe them
carefully as you work.
DANGER:
1. Always use the lithium ion battery pack or backup battery that is authorized by
Toshiba or compatible with the unit. Since other battery packs have different
specifications, they may be incompatible with the unit, and may burst or explode.
Heating or disassembling the battery pack could cause leakage of alkaline solution.
Throwing the battery pack into a fire could cause the battery pack to explode.
2. The power supply, FL inverter and other components carry high voltages. To avoid
the risk of electric shock when you need to turn on the power of a partially
disassembled computer to check its operation, be very careful not to touch
connectors or components. Also, do not disassemble individual components in first-
level maintenance.
WARNING: To avoid the risk of electric shock or other injury:
1. Always turn the power off and disconnect the AC adaptor from the power source.
2. Remove any metal jewelry or accessories such as necklaces, bracelets, or rings.
Batteries in the computer retain an electrical charge so there is danger of electrical
shock even when the computer is disconnected from an AC power source.
3. Never work with wet or damp hands.
4. The computer contains sharp edges and corners: be careful not to injure yourself.
5. Make sure that all replacement components meet the specifications for the computer
and that all cables and connectors are securely fastened.
CAUTION: To avoid damage to the computer:
1. When you change a component, be sure the replacement component meets the required
specifications. Never use foreign parts.
2. Metal objects such as screws or paper clips which fall into the unit can cause a short-
circuit, fire, or other internal damage.
3. When assembling the computer, make sure you use the correct screws to secure the
various pieces in place. Screw sizes are listed in their corresponding figure. Make sure
all screws are securely fastened. Loose screws can cause short circuits, resulting in
heat, smoke, or fire.
4. Before removing an FRU or other component, make sure all cables to the component
have been disconnected.
5. If you use AC power, be sure to use the cable that came with the computer or one
recommended by Toshiba.

4 Replacement Procedures
Disassembly Procedures
The computer has two basic types of cable connectors:
ꢀ Pressure Plate Connectors
ꢀ Standard Pin Connectors
To disconnect a Pressure Plate connector, lift up the tabs on either side of the connector’s
plastic pressure plate and slide the cable out of the connector. To connect the cable to a
Pressure Plate connector, make sure the pressure plate is fully lifted and slide the cable into
the connector. Secure the cable in place by pushing the sides of the pressure plate down so
the plate is flush with the sides of the connector. Gently pull on the cable to make sure the
cable is secure. If you pull out the connector, connect it again making sure the connector’s
pressure plate is fully lifted when you insert the cable.
Standard pin connectors are used with all other cables. These connectors can be connected
and disconnected by simply pulling them apart or pushing them together.
Assembly Procedures
After you have disassembled the computer and fixed or repaired the problem that was
causing the computer to operate abnormally, you will need to reassemble the computer.
Install all the removed FRUs following the steps described in the corresponding sections in
this chapter.
While assembling the computer, remember the following general points:
ꢀ Take your time, making sure you follow the instructions closely. Most problems
arise when you get in a hurry assembling the computer.
ꢀ Make sure all cables and connectors are securely fastened.
ꢀ Before securing the FRU or other parts, make sure that no cables will be pinched
by screws or the FRU.
ꢀ Check that all latches are closed securely.
ꢀ Make sure all the correct screws are used to secure all FRUs. Using the wrong
screw can either damage the threads on the screw or the head of the screw and
may prevent proper seating of an FRU.
After installing an FRU in the computer, confirm that the FRU and the computer are
functioning properly.

Appendix A
Appendix A Handling the LCD Module
Precautions for handling the LCD module
The LCD module can be easily damaged during assembly or disassembly. Therefore, please
observe the following precautions when handling it:
1. When installing the LCD module in the LCD cover, be sure to seat it so that it is
properly aligned and maximum visibility of the display is maintained.
2. Be careful to align the holes at the four corners of the LCD module with the
corresponding holes in the LCD cover before securing the module with screws.
Do not force the module into place, because stress can affect its performance.
Note: The panel’s polarized surface is easily scarred, so handle it carefully.

3. If the panel’s surface gets dirty, wipe it with cotton or a soft cloth. If it is still dirty,
try breathing on the surface to create a light condensate and wipe it again.
If the surface is very dirty, we recommend a CRT cleaning agent. Apply the agent to
a cloth and then wipe the panel’s surface. Do not apply cleanser directly to the panel.

4. If water or other liquid is left on the panel’s surface for a long period, it can change
the screen’s tint or stain it. Be sure to quickly wipe off any liquid.

5. Glass is used in the panel, so be careful not to drop it or let it strike a hard object,
which could cause breakage or cracks.
6. CMOS-LSI circuits are used in the module, so guard against damage from
electrostatic discharge. Be sure to wear a wrist or ankle ground when handling the
module.

7. Do not expose the module to direct sunlight or strong ultraviolet rays for long
periods.
8. Do not store the module at temperatures below specifications. Cold can cause the
liquid crystals to freeze, lose their elasticity or otherwise suffer damage.
9. Do not disassemble the LCD module. Disassembly can cause malfunctions.

10. If you transport the module, do not use packing material that contains epoxy resin
(amine) or silicon glue (alcohol or oxime). These materials can release gas that can
damage the panel’s polarization.
