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