Replacing the Palm Rest
To aid with proper flex cable connection, a white locator line has been \
added near the 
ends of the flex cables. When replacing the LED and palm-rest flex cable\
s, press the 
cable into the connector until the white line disappears and hold it ste\
ady while you 
snap the flex cable connector down. (The white line may reappear after \
the connector 
is closed; this should not indicate a problem with the connection.)
