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.
