Before removing the 
replacement LCD panel from its anti-static bag, we 
do one last check to ensure the data cable connectors are the same spot. The 
connectors line up perfectly (see: orange lines, below), so we're ready to unscrew the 
final screws holding the cracked LCD panel from the metal frame and make the 
swap.
Undo 
the screws which connect the metal frame to 
the LCD screen panel. There are two screws along the top edge and two more by the 
hinges.
After the last two screws are removed, carefully slide 
the broken LCD panel out and set it aside.
We now have three different sets of screws, grouped 
according to where they go in the notebook. The foam really helps organize these 
tiny fasteners.
