Disassembly Process
The disassembly process is divided into the following stages:
TExternal module disassembly
TMain unit disassembly
TLCD module disassembly
The flowcharts provided in the succeeding disassembly sections illustrate the entire disassembly sequence. 
Observe the order of the sequence to avoid damage to any of the hardware components. For example, if you 
want to remove the mainboard, you must first remove the keyboard, then disassemble the inside assembly 
frame in that order.
