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 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 screws. 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.

Chapter 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 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 reassembly 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.

Chapter 4 Replacement Procedures

Disassembly Procedure

Three main types of cable connector are used.

???Pressure plate connector

???Spring connector

???Normal pin connector

When disconnecting a pressure plate connector, lift up the tag 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, lift up the pressure plate to a suitable height and insert the cable into the connector. Press down on 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 lift the pressure plate high enough 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.

Chapter 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

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.

???M2.5 (2.5mm) 0.392 N??m(4.0 kgf??cm) for Hinge support

NOTE: To prevent damage to THIN HEAD screws, 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

Handling the LCD Module

3.If the panel???s surface gets fingerprint or dust, put on gloves and wipe it with static electricity cloth. If it is still dirty, drop some cleaning alcohol on the surface and wipe it again.

If the surface is much more fingerprint or dust, 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.

If dust still exists, please use ionic FAN which can avoid static electricity to deal with it.

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 with cloth or ionic

FAN

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.
