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.

4 Replacement Procedures 4.1 Overview
Safety Precautions
Please read the following safety instructions before disassembling the computer and
always follow the instructions while working on the computer.
Danger: 1. In the case of the battery, always use authentic parts or equivalent parts
approved by Toshiba. Other batteries may have different specifications
that are incompatible with the computer and may result in fire or
explosion.
Due to the risk of alkali fluid leaks, never attempt to heat or disassemble
the battery. Similarly, due to the risk of explosion, never expose the
battery to flame.
2. Some parts including the power supply and FL inverter generate high
voltages. If you need to turn on the power while disassembling the
computer, do not touch any connectors or other components due to the
risk of electric shock. Also, do not disassemble individual parts when
performing routine maintenance.
Warning:1. To prevent electric shock, turn off the power and unplug the AC adapter
from the power source.
2. As the battery installed to the computer is typically already charged, the
risk of electric shock remains even when the AC adapter is unplugged
from the socket. To prevent electric shock, always take off any metal
jewelry or accessories such as necklaces, bracelets or rings before
working on the computer. Never work with wet or moist hands.
3. Take care not to injury yourself on any edges or corners.
Caution: 1. Confirm that replacement parts have compatible specifications before
replacing on the computer. Never use incorrect parts as these may cause
faults on the computer.
2. To prevent internal damage such as short circuits or burning, do not allow
any screws, paper clips, or other metal objects to fall into the computer.
When removing screws, always replace with the same size screw. Ensure
that all screws are fully tightened. Loose screws may result in short
circuits leading to overheating, smoke or flame.
3. To prevent electric shock, check that you have disconnected all cables
from a part before removing the part.
4. When connecting to the AC power supply, use only an AC adapter and
cable approved by Toshiba.
5. To prevent electric shock, ensure that all replacement parts are
compatible with the computer and that all cables and connectors are
securely connected.

4.1 Overview 4 Replacement Procedures
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 “4.2.1 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.
Portege M200 Maintenance Manual (960-457) 4-3
4 Replacement Procedures 4.1 Overview
Disassembly Procedures
Three main types of cable connector are used.
❑ Pressure plate connector
❑ Spring connector
❑ Normal pin connector
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.
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.
Normal pin connectors are used for all other cables. Simply pull out or push in these
connectors to disconnect or reconnect.

4.1 Overview 4 Replacement Procedures
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)
❑ 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
❑ Air-ionizers in highly static sensitive areas
❑ Antenna coaxial cable disconnector

4 Replacement Procedures 4.1 Overview
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: To prevent damage to THIN HEAD screws, use type 0 pit philips screwdriver.
Use, however, the PH point size “1” screwdriver for screws fixing the expansion
memory slot cover and the keyboard.. Press along the axis of the screwdriver
while turning the screw. This is because the contact area between the screw and
driver is less than for a pan head screw (standard pan-shaped screw head).
Grip Color
Some screws have a colored grip area to help you determine the length of the screw.
❑ Even numbered length screws: Brown
❑ Odd numbered length screws: White
❑ Special length screw: Blue
“Special length screw” means screws whose length is indicated
Grip area
in an integral number to the first decimal places such as 2.5 mm,
2.6 mm and so on.
