4 Replacement Procedures

4.1 General

This chapter explains how to disassemble the computer 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.

How to use the chart (two examples):

For removing the System Board:

First, remove Base Enclosure,

Battery Pack and display assembly.

Then, remove HDD, SSD, Smart

Card Board, DC IN harness, and wireless LAN card, all of which are shown above the System

Board.

For removing the LCD Module:

First, remove the display mask, both of which are shown above the

LCD module.

Safety Precautions

Before you begin to 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 computer. 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 FL inverter carry high voltages.

When you partially disassemble the computer 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 computer off and remove the AC adapter from the electrical outlet.

2. Because the battery in the computer 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 computer 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 computer or Toshiba-recommended equivalents.

5. To avoid the risk of electrical shock, make sure that all the replacement components meet the specifications of the computer 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 disassembly the computer, 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 computer only when an abnormality has occurred.

Use only the recommended tools.

To run and store the computer, 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 3 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 computer 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 computer, 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 computer 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 comes 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 computer after you have disassembled the computer and fixed the component that caused the problem.

When reassembling the computer, keep the following general guidelines in mind:

Be careful to align the four holes at the right side and left side of the LCD module with the corresponding holes in the LCD cover before securing the module with four screws. Do not force the module into place, because stress can affect its performance.

Also, t he panel’s polarized surface is easily scarred, so be carefully when handling it.

Appendices Apx. A Handling the LCD Module

3.

If the panel’s surface gets dirty, 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 cloth and then wipe the panel’s surface. Do not apply

cleanser directly to the panel.

Also, never scratch the surface.

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.

Apx. A Handling the LCD Module Appendices

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 ground when handling the module.

Appendices Apx. A Handling the LCD Module

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 specifications. Cold can cause the liquid crystals to freeze, lose their elasticity or otherwise suffer damage.

Apx. A Handling the LCD Module Appendices

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 oxide). These materials can release gas that can damage th e panel’s polarization.

11.

For the module with touch screen function, please be careful about the retro type around the LCD bezel. If the retro is broken or dirty, the function of touch screen will be effect.
