							Error! Style not defined. Error! Style not defined.   4 Replacement Procedures  
4.1  General 
This chapter explains how to disassemble the  laptop and replace Field Replaceable Units (FRUs). 
Some replacement procedures may not require you to remove all the surrounding FRUs to 
replace only one FRU. The chart below shows the FRUs in the order in whi\
ch they should be 
removed in a top-down manner, irrespective of their physical locations. The FRUs shown in the 
top area of the chart should normally be removed before removing the FRUs shown in the 
bottom area. To replace the FRUs, first identify the suspect FRU for the syste\
m failure. Next, 
according to this chart, determine the FRUs that need to be removed before removing the suspect 
FRU. After you determine those FRUs, go to the appropriate sections according to the section \
numbers shown in the boxes. Then start removal and replacement.

Safety Precautions 
Before you begin disassembly read the following safety precautions carefully. Be sure to follow 
them while you are working.  
DANGER: 
1.  Always use the genuine batteries or replacement batteries authorized by \
Toshiba. 
Batteries other than those differ in specifications and are incompatible\
 with the laptop. 
They may burst or explode. To avoid leakage of alkaline solutions, never\
 heat or 
disassemble the battery packs. Never throw the battery packs into a fire\
. If this is 
violated, they will explode. 
2.  The components such as the power supply and inverter carry high voltages\
. When you 
partially disassemble the laptop and turn on the components, use extreme\
 care not to 
touch the connectors and components to avoid the risk of electrical shoc\
k. Do not 
disassemble individual components during first-level maintenance. 
 
WARNING: 
1.  To avoid the risk of electrical shock, turn the laptop off and remove th\
e AC adapter from 
the electrical outlet. 
2.  Because the battery in the laptop is left charged, the risk of electrica\
l shock remains 
even after the AC adapter is removed from the electrical outlet. To avoi\
d the risk of 
electrical shock, be sure to remove any metal jewelry or accessories suc\
h as necklaces, 
bracelets, and rings before starting work. Never work with damp or wet h\
ands. 
3.  To avoid personal injury, use care to avoid the sharp edges or corners o\
f the 
components.
