Preface  
This maintenance manual describes how to perform hardware service maintenance for the Toshiba  
Personal Computer Satellite, referred to as the Satellite Series in this manual.  
The procedures described in this manual are intended to help service technicians isolate faulty  
Field Replaceable Units (FRUs) and replace them in the field.  
SAFETY PRECAUTIONS  
Four types of messages are used in this manual to bring important information to your attention.  
Each of these messages will be italicized and identified as shown below.  
DANGER: “Danger” indicates the existence of a hazard that could result in death or  
serious bodily injury if the safety instruction is not observed.  
WARNING: “Warning” indicates the existence of a hazard that could result in bodily  
injury if the safety instruction is not observed.  
CAUTION: “Caution” indicates the existence of a hazard that could result in property  
damage if the safety instruction is not observed.  
NOTE: “Note” contains general information that relates to your safe maintenance  
service.  
Improper repair of the computer may result in safety hazards. Toshiba requires service technicians  
and authorized dealers or service providers to ensure the following safety precautions are adhered  
to strictly.  
Be sure to fasten screws securely with the right screwdriver. If a screw is not fully fastened, it  
could come loose, creating a danger of a short circuit, which could cause overheating,  
smoke or fire.  
If you replace the battery pack or RTC battery, be sure to use only the same model battery or  
an equivalent battery recommended by Toshiba. Installation of the wrong battery can  
cause the battery to explode.

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.

4 Replacement Procedures  
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 removing 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.

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.

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.

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 grounding device when handling the module.

Download from Www.Somanuals.com. All Manuals Search And Download.  
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 its 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.
