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 careful not to touch connectors or components. Also, do not disassemble individual components during first-level maintenance. WARNING: To avoid the risk of electric shock or other injury: 1. Always turn the power off and disconnect the AC power cord from the power source. 2. Remove any metal jewelry or accessories such as necklaces, bracelets, or rings. 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. 3. Never work with wet or damp hands. 4. The computer contains many sharp edges and corners, so 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.

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 careful
not to touch connectors or components. Also, do not disassemble individual
components during first-level maintenance.
WARNING:
To avoid the risk of electric shock or other injury:
1.
Always turn the power off and disconnect the AC power cord from the
power source.
2.
Remove any metal jewelry or accessories such as necklaces, bracelets, or
rings. 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.
3.
Never work with wet or damp hands.
4.
The computer contains many sharp edges and corners, so 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.
2.
Metal objects such as screws or paper clips which fall into the unit can cause
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 the 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 removed.
5.
If you use AC power, be sure to use the cable that came with the computer
or one recommended by Toshiba.
