Disassembly Process
IMPORTANT: The LCD Module cannot be disassembled outside of factory conditions. If any part of the LCD 
Module is faulty, such as the camera, antenna or LCD panel, the whole module must be replaced. 
The disassembly process is divided into the following stages:
•External module disassembly
•Main unit disassembly
•LCD 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.
