1.6 Batteries 1 Hardware Overview
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 charge: 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.
Status Charging time
Normal charge (power on) 12 hours or longer
Quick charge (power off) About 4 hours or longer
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 backup battery that is authorized by
Toshiba or 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 in firstlevel 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 necklaces, bracelets, or rings.
Batteries in the computer retain an electrical charge so there is 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, be sure the replacement component meets the required
specifications. Never use foreign parts.
2. Metal objects such as screws or paper clips which fall into the unit can cause a shortcircuit, 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.

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 will be pinched by
screws or the FRU.
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.

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 scarred, so handle it carefully.

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.
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.
