Safety Precautions - Toshiba 100CS Manual

Safety Precautions

Before you begin disassembly, read the following safety precautions and observe them care-
fully as you work.
DANGER:
1. Always use the lithium ion battery pack or back-up battery that is authorized by
Toshiba or compatible with the unit. Since other battery packs have different specifi-
cations, they may be incompatible with the unit, and may burst or explode. Heating
or disassembling the battery pack could cause leakage of alkaline solution. Throw-
ing 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 turn on the power of a partially disassembled
computer to check its operation, be very careful not to touch connectors or compo-
nents. 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. Never use foreign parts.
2. Be sure metal objects such as screws or paper clips do not fall into the unit, they
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 figures. Make
sure all screws are securely fastened. Loose screws can cause short circuits, result-
ing 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 recom-
mended by Toshiba.
