1.6.1 Main Battery

Battery charging is controlled by a power supply microprocessor that is mounted on the system board. The power supply microprocessor controls whether the charge is on or off and detects a full charge when the AC adaptor and battery are attached to the computer. The system charges the battery using quick charge or trickle charge.

Quick Battery Charge

When the AC adaptor is attached, there are two types of quick charges: quick charge when the system is powered off and normal charge when the system is powered on.

The times required for charges are listed in the table below.

Normal charge (power on)

Quick charge (power off)

12 hours or longer

About 4 hours

NOTES

1. The time required for normal charge is affected by the amount of power the system is consuming. Use of the fluorescent lamp and frequent disk access diverts power

and lengthens the charge time.

2. Using quick charge, the power supply microprocessor automatically stops the charge after eight hours regardless of the condition of the battery. Overcharging

could cause the battery to explode.

If any of the following occurs, the battery quick charge process stops.

1. The battery becomes fully charged.

2. The AC adaptor or battery is removed.

3. The battery or output voltage is abnormal.

4. The battery temperature is abnormal.

5. The battery SMBus communication fails.

6. The battery cell is bad.

Detection of full charge

A full charge is detected from the battery pack through SMBus when the battery is charging.

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 a backup battery that is authorized by

Toshiba or is 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. To avoid the risk of electric shock when you need to turn on the power of a partially disassembled computer to check its operation, be very careful not to touch connectors or components. Also, do not disassemble individual components for first-

level maintenance.

WARNING: To avoid the risk of electric shock or other injury:

1.

Always turn the power off and disconnect the AC adaptor from the power source.

2. Remove any metal jewelry or accessories such as watches, necklaces, bracelets, or rings. Batteries in the computer retain an electrical charge so there is a danger of

electrical shock even when the computer is disconnected from an AC power source.

3.

Never work with wet or damp hands.

4.

The computer contains sharp edges and corners. Be careful not to injure yourself.

5. Make sure that all replacement components meet the specifications for the computer

and that all cables and connectors are securely fastened.

CAUTION: To avoid damage to the computer:

1. When you change a component, make sure that the replacement component meets the

required specifications. Never use foreign or incompatible parts.

2. Metal objects such as screws or paper clips which fall into the unit can cause a short-

circuit, fire, or other internal damage.

3. When assembling the computer, make sure you use the correct screws to secure the various pieces in place. Screw sizes are listed in their corresponding figure. Make sure all screws are securely fastened. Loose screws can cause short circuits, resulting in

heat, smoke, or fire.

4. Before removing an FRU or other component, make sure all cables to the component

have been disconnected.

5. If you use AC power, be sure to use the cable that came with the computer or one

recommended by Toshiba.

Before You Begin

Look over the procedures in this section before you begin disassembling the computer.

Familiarize yourself with the disassembly and reassembly steps. Begin each procedure by removing the AC adaptor and the battery pack as instructed in section 4.2.

1. Do not disassemble the computer unless it is operating abnormally.

2. Use only the correct and approved tools.

3. Make sure the working environment is free from the following elements whether you are using or storing the computer.

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 troubleshooting and diagnostics tests described in chapters 2 and 3 of 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 computer.

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

8. When assembling the computer make sure you use the correct screws to secure the various pieces. Screw sizes are listed in their corresponding figures.

9. The computer contains many sharp edges and corners, so be careful not to injure yourself.

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

4-4

[CONFIDENTIAL]


Disassembly Procedures

The computer has two basic types of cable connectors:

Pressure Plate Connectors

Standard 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.

Assembly Procedures

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

Install all the removed FRUs following the steps described in the corresponding sections in this chapter.

While assembling the computer, remember the following general points:

Take your time, making sure you follow the instructions closely. Most problems arise when you get in a hurry assembling the computer.

Make sure all cables and connectors are securely fastened.

Before securing the FRU or other parts, make sure that no cables are pinched by screws or the FRUs.

Check that all latches are closed securely.

Make sure all the correct screws are used to secure all FRUs. Using the wrong screw can either damage the threads on the screw or the head of the screw and may prevent proper seating of an FRU.

After installing an FRU in the computer, confirm that the FRU and the computer are functioning properly.

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 p recautions 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 m aximum visibility of the display is ma intained.

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 recom me nd 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.


[CONFIDENTIAL]

A-3

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.

A-4

[CONFIDENTIAL]


7. Do not expose the mo dule 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.


[CONFIDENTIAL]

A-5

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.
