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 an 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.
