General Information
Before You Begin
Before proceeding with the disassembly procedure, make sure that you do the following:
1.
Turn off the power to the system and all peripherals.
2.
Unplug the AC adapter and all power and signal cables from the system.
3.
Remove the battery pack.
Connector Types
There are two kinds of connectors on the system board: 

Connectors with no locks
Unplug the cable by simply pulling out the cable from the connector.

Connectors with locks
You can use a plastic stick to lock and unlock connectors with locks.
Unplugging the cable with locks
To unplug the cable, first unlock the connector by pulling up the two clasps on both sides of the connector with 
a plastic stick. Then carefully pull out the cable from the connector.
Plugging the cable with locks
To plug the cable back, first make sure that the connector is unlocked, then plug the cable into the connector. 
With a plastic stick, press the two clasps on both sides of the connector to secure the cables in place.
NOTE: 
The cables used here are special FPC (flexible printed-circuit) cables and more delicate than normal 
plastic-enclosed cables.  Do not force cables out of the connectors to prevent damage.
