Safety precautions

Before you begin disassembly, read the following safety precautions and observe them carefully as you work.

DANGER: 1. Always use the lithium ion battery pack or the back-up battery authorized by Toshiba to be compatible with the unit. Since other battery packs have different specifications, they may be incompatible with the unit and may burst or explode.

Heating or disassembling the battery pack could cause leakage of alkaline solution. Throwing the battery pack into a fire could cause the battery pack to explode.

2. The power supply, FL inverter, and other components carry high voltages. If you turn on the power of a partially disassembled computer to check its operation, be very careful not to touch connectors or components. This will reduce the risk of accidental electrical shock. Also, do not disassemble individual components during first-level maintenance.

4-1

Observe the following Cautions and Warnings when you change an FRU or other component.

WARNING: 1. Turn off the power and disconnect the AC power cord or AC adapter from the power source; exposure to electric shock hazards may occur.

2. Batteries in the computer retain electrical charge, so there is danger of electrical shock even when the computer is disconnected from an AC power source. To reduce the risk of accidental electric shock, remove any metal jewelry or accessories such as necklaces, bracelets or rings..

Never work with wet or damp hands.

3. The 610CT contains many sharp edges and corners, so be careful not to injure yourself.

CAUTION: 1. When you change a component, be sure the replacement component meets the required specifications. To avoid any risk of damage to the computer, never use foreign parts.

2. To avoid any risk of short-circuit, fire, or other internal damage, never allow any metal objects such as screws or paper clips to fall into the unit. Be sure to replace screws with the same size as those removed.

Screw sizes are listed in the corresponding figures. Make sure all screws are securely fastened. Loose screws can cause short circuits, resulting in heat, smoke, or fire.

3. To reduce the risk of accidental electric shock before lifting out an

FRU or other component, make sure all cables to the component have been disconnected.

4. Be sure to use the correct AC adapter. Use of the wrong adapter could cause reverse polarity resulting in smoke, fire, or other equipment damage.

5. To avoid the risk of accidental electric shock, make sure that all replacement components meet the specifications for the computer and that all cables and connectors are securely fastened.

❑

❑

❑

Dust and contaminates

Static electricity

Extreme heat, cold, and humidity

4.

Make sure the FRU you are replacing is causing the abnormal operation by performing the necessary diagnostics tests described in this manual.

5.

Do not perform any operations that are not necessary and use only the described procedures for disassembling and installing FRUs in the 610CT.

6.

After removing parts from the computer, place them in a safe place away from the computer so they will not be damaged and will not interfere with your work.

7.

You will remove and replace many screws when you disassemble the 610CT.

When you remove screws, make sure they are placed in a safe place and identified with the correct parts.

8.

After you have replaced an FRU make sure the 610CT is functioning properly by performing the appropriate test on the FRU you have fixed or replaced.

Disassembly Procedures

The 610CT has two basic types of cable connectors:

❑

❑

Pressure Plate Connectors

Normal Pin Connectors

To disconnect a Pressure Plate connector, lift up the tabs on either side of the connector's plastic pressure plate and slide the cable out of the connector. To connect the cable to a

Pressure Plate connector, make sure the pressure plate is fully lifted and slide the cable into the connector. Secure the cable in place by pushing the sides of the pressure plate down so the plate is flush with the sides of the connector. Gently pull on the cable to make sure the cable is secure. If you pull out the connector, connect it again making sure the connector’s pressure plate is fully lifted when you insert the cable.

Standard pin connectors are used with all other cables. These connectors can be connected and disconnected by simply pulling them apart or pushing them together.

610CT 4-3

Assembly Procedures

After you have disassembled the 610CT and fixed or repaired the problem that was causing the 610CT to operate abnormally, you will need to reassemble the 610CT.

Appendix A Handling the LCD Module

Precautions for Handling the LCD Module

The computer’s LCD module can be easily damaged during assembly or disassembly.

Therefore, please observe the following precautions when handling the LCD module.

1.

When installing the LCD module in the LCD cover, be sure to 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.

Also, the panel’s polarized surface is easily scarred, so be careful when handing it.

610CT A-1

A-2

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.

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.

610CT

610CT

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.

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.

A-3

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.
