4.1 General
This chapter explains how to disassemble the laptop and replace Field Replaceable Units (FRUs).
Some replacement procedures may not require you to remove all the surrounding FRUs to
replace only one FRU. The chart below shows the FRUs in the order in which they should be
removed in a top-down manner, irrespective of their physical locations. The FRUs shown in the
top area of the chart should normally be removed before removing the FRUs shown in the
bottom area. To replace the FRUs, first identify the suspect FRU for the system failure. Next,
according to this chart, determine the FRUs that need to be removed before removing the suspect
FRU. After you determine those FRUs, go to the appropriate sections according to the section
numbers shown in the boxes. Then start removal and replacement.

Safety Precautions
Before you begin disassembly read the following safety precautions carefully. Be sure to follow
them while you are working.
DANGER:
1. Always use the genuine batteries or replacement batteries authorized by Toshiba.
Batteries other than those differ in specifications and are incompatible with the laptop.
They may burst or explode. To avoid leakage of alkaline solutions, never heat or
disassemble the battery packs. Never throw the battery packs into a fire. If this is
violated, they will explode.
2. The components such as the power supply and inverter carry high voltages. When you
partially disassemble the laptop and turn on the components, use extreme care not to
touch the connectors and components to avoid the risk of electrical shock. Do not
disassemble individual components during first-level maintenance.
WARNING:
1. To avoid the risk of electrical shock, turn the laptop off and remove the AC adapter from
the electrical outlet.
2. Because the battery in the laptop is left charged, the risk of electrical shock remains
even after the AC adapter is removed from the electrical outlet. To avoid the risk of
electrical shock, be sure to remove any metal jewelry or accessories such as necklaces,
bracelets, and rings before starting work. Never work with damp or wet hands.
3. To avoid personal injury, use care to avoid the sharp edges or corners of the
components.

Satellite L450/Pro L450/L450D/Pro L450D Maintenance Manual 4-3
CAUTION:
1. Before replacing a component, make sure that the replacement component meets the
required specifications. To avoid laptop failures, never use components that do not meet
the specifications.
2. To avoid internal damage such as short circuits and fire, never drop metal objects such
as screws, pins, paper clips, etc. into the components. When a screw is removed, be sure
to replace a screw that is the same size as the original screw. Make sure that all the
screws are fastened securely. Loose screws can cause short circuits, overheating,
smoke, or fire.
3. Before raising a FRU or other component, make sure that all the component cables
have been disconnected to avoid the risk of electrical shock caused by accidental
contact with the energized components.
4. For AC input, be sure to use the AC adapter and AC power cable that come with your
laptop or Toshiba-recommended equivalents.
5. To avoid the risk of electrical shock, make sure that all the replacement components
meet the specifications of the laptop and that all the cables and connectors are fastened
securely.
6. Inside the PC are components that become hot during operation (such as the CPU and
cooling module). To avoid burns, let the hot components cool down before starting
inspection or repair task.

Before You Begin
Before you begin to disassemble the laptop, keep in mind the precautions and advice in this
section. Always begin disassembly by removing the AC adapter and battery pack. Remove the
optional parts and accessories as well. The procedures for removing the batteries will be
explained later.
Disassemble the laptop only when an abnormality has occurred.
Use only the recommended tools.
To run and store the laptop, be sure to prepare a working environment that is free from:
Dust and contaminants
Static electricity
Extremely high or low temperatures and extremely high humidity
Run the diagnostic tests explained in Chapter 2 of this manual to identify the FRU that has
probably caused the system failure.
Perform only the required machine operations. Use only the disassembly and reinstallation
procedures described in this manual.
Place the removed components in a safe place away from the laptop so that they are not damaged
or get in the way of you doing your work.
Normally, a number of screws need to be removed or replaced during disassembling. Place the
removed screws in a safe place so that you can easily find the right screws for the right
components.
When assembling the laptop, use the specified screws to fasten the parts to the specified
locations. See the appropriate explanations and figures for screw sizes.
To avoid personal injury, use care to handle components that have sharp edges or corners.
After you have replaced a FRU, check that the FRU works correctly to ensure normal laptop
operation.

Disassembly Procedures
The cable connectors come in these two basic types:
Pressure plate connectors
Normal pin connectors
To remove a pressure plate connector, pull up the tabs on either side of the connector's plastic
pressure plate and gently pull the cable out of the connector. To reconnect the cable to the
pressure plate's connector, raise the pressure plate up to a satisfactory height and slide the cable
into the connector. Secure the cable in the correct position by pressing down the sides of the
pressure plate so that the plate is flush with the sides of the connector. Grasp and pull the cable
gently to check that the cable is connected firmly. If the cable came off the connector, reinsert
the cable by raising the pressure plate up to a satisfactory height.
Normal pin connectors are used for all the other types of cables. These connectors can be
installed or removed by simply inserting them or pulling them out.
Assembly Procedures
You have to reassemble the laptop after you have disassembled the laptop and fixed the
component that caused the problem.
When reassembling the laptop, keep the following general guidelines in mind:
Take your time to carry out the suggested instructions completely. Hurried reassembly
can often cause problems.
Check that all the cable and connectors are fastened securely.
Before securing the FRUs or other parts, check that the cables are not caught by the
screws or FRUs.
Check that all the latches are closed securely.
Check that all the required screws are used to secure the FRUs. Using wrong screws can
damage the threads or heads of the screws or does not ensure that the FRUs are secure.
After installing a FRU, make sure that the FRU and laptop work normally.

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. Observe the following
precautions when handling it to prevent damaging it.
1. When installing the LCD module in the display assembly, make sure that you 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 scratched and damaged, so handle it
carefully.
Satellite L450/L450D Series Maintenance Manual

3. If the panel’s surface gets dirty or moist, 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
soft cloth and then wipe the panel’s surface. Do not apply cleanser directly to the panel.
CRT
Cleaner
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.
