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
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. Never use foreign parts.
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. 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.
