Cables 
Follow these guidelines when working with cables:
¥ Ensure all cables are routed exactly when reassembling. 
Use all grooves and/or protrusions to align cabling. If the 
cable is improperly routed, you may not be able to 
reassemble the computer, or once reassembled, the 
computer may fail to function.
¥ Check that all cables are properly aligned in the 
connectors and that the connections are tight.
¥ Handle flex cables carefully. Using excessive force to 
disconnect a cable can tear the cable or damage it so it will 
not work properly. 
¥ Use a nylon tool or dental pick to help loosen cable 
connections.
