4.1 Overview
This chapter describes the procedure for removing and replacing the field replaceable units
(FRUs) in the PC. It may not be necessary to remove all the FRUs in order to replace one.
The chart below provides a guide as to which other FRUs must be removed before a
particular FRU can be removed. The numbers in the chart indicate the relevant section
numbers in this manual.
In all cases when removing an FRU, the battery pack must also be removed. When repairing
an FRU that is the potential cause of a computer fault, use the chart to determine the order in
which FRUs need to be removed.
■Chart Notation
The chart shows the
case for the following
example:
◆Removing the touch
pad.
All FRUs of 4.2 Battery
from down to 4.6
Keyboard/Bottom cover
must be removed.

Safety precautions
Please read the following safety instructions before disassembling the computer and always
follow the instructions while working on the computer.
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.

PORTEGE R200 Maintenance Manual (960-519) [CONFIDENTIAL] 4-3
Before You Begin
Take note of the following points before starting work. Always remove the AC adapter and
battery pack before commencing any of the procedures. The procedure for removing the
battery pack is described in section “4.2 Battery Pack”.
1. Do not disassemble the computer unless it is operating abnormally.
2. Use the designated tools.
3. Ensure that the environment for working on and storing parts does not contain any of
the following.
❑Dust or dirt
❑Static electricity
❑Extremely hot, cold, or humid conditions
4. Perform the diagnostic tests described in Chapter 2 to determine which FRU is the
cause of the fault.
5. Do not perform any unnecessary work. Always work in accordance with the
disassembly and re-assembly procedures in this manual.
6. Keep parts removed from the computer in a safe place away from the computer where
they will not be damaged or interfere with your work.
7. Disassembling requires the removal of a large number of screws. Keep removed
screws in a safe place such that you can determine which screws belong to which part.
8. When reassembling, ensure that you use the correct screws and fit parts in the correct
position. Screw sizes are noted in the text and figures.
9. As all parts have sharp edges and corners, take care not to cut yourself.
10. After replacing an FRU, check that the computer and replaced part operate correctly.

4 Replacement Procedures 4.1 Overview
4-4 [CONFIDENTIAL] PORTEGE R200 Maintenance Manual (960-519)
Disassembly Procedures
Three main types of cable connector are used.
❑Pressure plate connector
❑Spring connector
❑Normal pin connector
1. When disconnecting a pressure plate connector, draw the tab on one side of the plastic
pressure plate on the connector and pull the cable out from the connector. When
reconnecting a cable to a pressure plate connector, draw enough the pressure plate
and insert the cable into the connector. Press both sides of the pressure plate such that
both sides of the plate and connector are at the same height and that the cable is fixed
in the correct position. Pull the cable to ensure that it is securely connected. If the
cable is disconnected from the connector, reconnect it making sure that you draw
enough the pressure plate to insert fully the cable.
2. For spring connectors, lifting up the stopper frees the cable and allows it to be pulled
out. To reconnect, hold the stopper in the up position and insert the cable, then lower
the stopper to secure the cable.
3. Normal pin connectors are used for all other cables. Simply pull out or push in these
connectors to disconnect or reconnect.

PORTEGE R200 Maintenance Manual (960-519) [CONFIDENTIAL] 4-5
Assembly Procedure
After the computer has been disassembled and the part that caused the fault has been repaired
or replaced, the computer must be reassembled.
Take note of the following general points when assembling the computer.
❑Take your time and follow the instructions carefully. Hurrying the assembly work
will only introduce new problems.
❑Check that all cables and connectors are securely connected.
❑Before fastening FRUs or other parts in place, ensure that no cables are caught on
screws or the FRU.
❑Check that all latches are securely closed.
❑Ensure that you have installed all FRUs correctly and do not have any screws left
over. Using an incorrect screw may damage the thread or screw head and result in the
FRU not being securely fastened in place.
After installing FRUs, check that the computer operates correctly.
Tools and Equipment
For your safety and the safety of the people around you, it is important that you use
Electrostatic Discharge (ESD) equipment. Correctly utilizing of the equipment increases the
percentage of successful repairs and saves on the cost of damaged or destroyed parts. The
following equipment is required for disassembly and assembly.
❑One Philips screwdriver with type 0 bit (for THIN HEAD screws)
❑One Philips screwdriver with type 1 bit (for screws other than above)
❑One screwdriver for LH sticks (for Mini PCI card cover)
❑Tweezers (for lifting screws)
❑ESD mats (lay on work table or floor)
❑An ESD wrist strap and heel grounder
❑Anti-static carpet or flooring
❑A pair of needle-nose pliers

Screw Tightening Torque
Use the following torque when tightening screws.
CAUTION: Overtightening may damage screws or parts. Undertightening may allow
screws to loosen (and possibly fall out) causing a short circuit or other
damage.
NOTE: To tighten screws quickly and accurately, an electric screwdriver is
recommended.
❑M2 (2mm) 0.167 N·m (1.7 kgf·cm)
❑M2.5 (2.5mm)0.294 N·m(3.0 kgf·cm)
❑M3 (3mm) 0.549 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.
