4.1 General
This section explains how to disassemble the computer and replace Field Replaceable Units
(FRUs). It may not be necessary to remove all the FRUs in order to replace one. The chart
below is a guide to which FRUs need to be removed in order to remove others. Always start
by removing the battery pack, next, optional items such as the optional PC card and optional
SD card, then follow the line on the chart to determine which FRU you must remove next in
order to repair the one you think is causing the computer to operate improperly. Refer to the
example at the bottom of the page.

Safety Precautions
Before you begin disassembly, read the following safety precautions and observe them
carefully as you work.
DANGER: 1) Always use the genuine 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.
Never heat or disassemble the battery pack, as that could cause leakage
of alkaline solution. Never throw the battery pack into a fire, as that
could cause the battery pack to explode.
2) The power supply, FL inverter and other components carry high
voltages. If 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, in order to avoid the risk of electric shock.
Also, do not disassemble individual components in first-level
maintenance.
WARNING: 1) Turn off the power and disconnect the AC adaptor from the power
source, to avoid exposure to electric shock.
2) 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. Remove any metal jewelry or accessories such as
necklaces, bracelets or rings, in order to reduce the risk of electric
shock. Never work with wet or damp hands.
3) Be careful of edges and corners as these may cut.
CAUTION: 1) When you change a component, be sure the replacement component
meets the required specifications. Never use foreign parts, to avoid any
risk of damage to the computer.
2) To avoid any risk of short-circuit, fire or other internal damage, never
allow any metal objects such as screws or paper clips to fall into the
unit. Be sure to replace screws with the same size as those removed.
Make sure all screws are securely fastened. Loose screws can cause
short circuits, resulting in heat, smoke or fire.
3) Before lifting out an FRU or other component, make sure all cables to
the component have been disconnected, in order to reduce the risk of
accidental electric shock.
4) If you use AC power, be sure to use the cable that came with the
computer or one recommended by Toshiba.
5) Make sure that all replacement components meet the specifications for
the computer and that all cables and connectors are securely fastened, in
order to avoid the risk of electric shock.
6) Some parts inside the computer, such as the CPU and cooling module,
become very hot during operation. Conduct repair work after they have
cooled. Be careful around the CPU and cooling module to avoid burns.

4.1 General 4 Replacement Procedures
Before You Begin
Look over the procedures in this section before you begin disassembling the computer.
Familiarize yourself with the disassembly and reassembly steps. Begin each procedure by
removing the AC adapter and the battery pack as instructed in this section:
1. Do not disassemble the computer unless it is operating abnormally.
2. Use only the correct and approved tools.
3. Make sure the working environment is free from the following elements whether you
are using or storing the computer.
• Dust and contaminates
• Static electricity
• Extreme heat, cold and humidity
4. Make sure the FRU you are replacing is causing the abnormal operation by
performing the necessary diagnostics tests described in this manual.
5. Do not perform any operations that are not necessary and use only the described
procedures for disassembling and installing FRUs in the computer.
6. After removing parts from the computer, place them in a safe place away from the
computer so they will not be damaged and will not interfere with your work.
7. You will remove and replace many screws when you disassemble the computer.
When you remove screws, make sure they are placed in a safe place and identified
with the correct parts.
8. 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 figures.
9. The computer contains many sharp edges and corners, so be careful not to injure
yourself.
10. After you have replaced an FRU, make sure the computer is functioning properly by
performing the appropriate test on the FRU you have fixed or replaced.

4 Replacement Procedures 4.1 General
Disassembly Procedures
The computer has two basic types of cable connectors:
• Pressure Plate Connectors
• Coaxial Cable Connectors
• Normal 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.
Coaxial cables should be disconnected with an antenna coaxial disconnector.
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 screws or the FRU will
pinch no cables.
• Check that all latches are closed securely in place.
• 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.

Tools and Equipment
The use of Electrostatic Discharge (ESD) equipment is very important for your safety and the
safety of those around you. Proper use of these devices will increase the success rate of your
repairs and lower the cost for damaged or destroyed parts. The following equipment is
necessary to disassemble and reassemble the computer:
• One M2 point size 0 Phillips screwdriver to remove and replace screws.
• One M2.5/M3 point size 1 Phillips screwdriver to remove and replace screws.
• One 4 mm flat-blade screwdriver.
• Tweezers, to lift out screws that you cannot grasp with your fingers.
• ESD mats for the floor and the table you are working on.
• An ESD wrist strap or heel grounder.
• Anti-static carpeting or flooring.
• Air ionizers in highly static sensitive areas.
• Antenna coaxial cable disconnector

Screw Tightening Torque
When you fasten screws, be sure to follow the torque list below.
CAUTION: Overtightening can damage components and screws; undertightening can
result in electrical shorts or other damage if screws or components come
loose.
NOTE: Toshiba recommends that you use an electric screwdriver for quick and easy
operations.
• M2 0.17 N·m (1.7 kgf·cm)
• M2.5 0.30 N·m (3.0 kgf·cm)
• M3 0.57 N·m (5.6 kgf·cm)
NOTE: The computer contains several flat head screws. These screws have less contact
area with the screwdriver, so be careful to press firmly enough to prevent the
screwdriver from slipping out and damaging the screw head.
