Before you proceed, make sure you pay special attention to the way the small plastic part that covers the radiator fins is held in place. You will need to know how it attaches when you reassemble the laptop.
You do not need to actually remove the part at this time. It is held in place by the rest of the back cover and will fall off when back cover is removed in the next step.
To start removing the speaker cover, use your finger to lift up on the exposed corner of the black speaker cover, located near the bottom left corner of the screen.
Slowly pull the speaker cover off from left to right, making sure it snaps off little by little.
At this point the speaker cover and keyboard should be removed and the laptop should be sitting in its normal open position with the screen facing you.
Once the new screen and its cables are securely in place, attach the three cables to their corresponding ports.
For each cable, place the connector on top of the port and align the two as close as possible.
To connect the power cable, use your finger to push downward on the middle of the connector until it snaps into place.
To connect each display cable, use the flat end of a spudger to press on the top of the silver connector until it snaps into place.
Snapping the connectors into place does require a little bit of force, but be careful, too much force can break the motherboard. If the connector doesn't snap into place with a moderate amount of force, realign it and try again.
Make sure the two display cables are connected to the correct ports. The grey cable should connect closest to the screen.
