Safety Precautions 
Before you begin disassembly, read the following safety precautions and observe them 
carefully as you work. 
DANGER:  1)  Always use the genuine 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.     
Never heat or disassemble the battery pack, as that could cause 
leakage of alkaline solution.    Never throw the battery pack into a 
fire, as that could cause the battery pack to explode. 
 
2)  The power supply, FL inverter and other components carry high 
voltages.    If 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, in order to avoid the risk of electric 
shock. 
Also, do not disassemble individual components in first-level 
maintenance. 
WARNING: 1)  Turn off the power and disconnect the AC adaptor from the power 
source, to avoid exposure to electric shock. 
 
2)  Batteries in the computer retain an electrical charge, so there is 
danger of electrical shock even when the computer is disconnected 
from an AC power source.    Remove any metal jewelry or 
accessories such as necklaces, bracelets or rings, in order to reduce 
the risk of electric shock.    Never work with wet or damp hands. 
 
3)  Be careful of edges and corners as these may cut. 
CAUTION:  1)  When you change a component, be sure the replacement component 
meets the required specifications.    Never use foreign parts, to avoid 
any risk of damage to the computer. 
 
2)  To avoid any risk of short-circuit, fire or other internal damage, 
never allow any metal objects such as screws or paper clips to fall 
into the unit.    Be sure to replace screws with the same size as those 
removed.    Make sure all screws are securely fastened.    Loose 
screws can cause short circuits, resulting in heat, smoke or fire. 
 
3)  Before lifting out a FRU or other component, make sure all cables to 
the component have been disconnected, in order to reduce the risk of 
accidental electric shock. 
 
4)  If you use AC power, be sure to use the cable that came with the 
computer or one recommended by Toshiba. 
 
5)  Make sure that all replacement components meet the specifications 
for the computer and that all cables and connectors are securely 
fastened, in order to avoid the risk of electric shock. 
 
6)  Some parts inside the computer, such as the CPU and cooling 
module, become very hot during operation.  Conduct repair work 
after they have cooled.    Be careful around the CPU and cooling 
module to avoid burns.
