Safety Precautions
Please read the following safety instructions before disassembling the computer and always
follow the instructions while working on the computer.
DANGER: 1. In the case of the battery, always use authentic parts or equivalent parts
approved by Toshiba. Other batteries may have different specifications
that are incompatible with the computer and may result in fire or
explosion.
Due to the risk of alkali fluid leaks, never attempt to heat or disassemble
the battery. Similarly, due to the risk of explosion, never expose the
battery to flame.
2. Some parts including the power supply and FL inverter generate high
voltages. If you need to turn on the power while disassembling the
computer, do not touch any connectors or other components due to the
risk of electric shock. Also, do not disassemble individual parts when
performing routine maintenance.
WARNING: 1. To prevent electric shock, turn off the power unplug the AC adapter from
the power source.
2. As the battery installed to the computer is typically already charged, the
risk of electric shock remains even when the AC adapter is unplugged
from the socket. To prevent electric shock, always take off any metal
jewelry or accessories such as necklaces, bracelets or rings before
working on the computer. Never work with wet or moist hands.
3. Take care not to injury yourself on any edges or corners.
CAUTION: 1. Confirm that replacement parts have compatible specifications before
replacing on the computer. Never use incorrect parts as these may cause
faults on the computer.
2. To prevent internal damage such as short circuits or burning, do not
allow any screws, paper clips, or other metal objects to fall into the
computer. When removing screws, always replace with the same size
screw. Ensure that all screws are fully tightened. Loose screws may
result in short circuits leading to overheating, smoke or flame.
3. To prevent electric shock, check that you have disconnected all cables
from a part before removing the part.
4. When connecting to the AC power supply, use only an AC adapter and
cable approved by Toshiba.
5. To prevent electric shock, ensure that all replacement parts are
compatible with the computer and that all cables and connectors are
securely connected.
