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 
screws. 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.
