Disconnect the display cables connecting the screen to the motherboard. Use your plastic putty knife to gently lift up the top casing holding the screen into place. Remove the screws around the screen, and disconnect the cables at the bottom of the screen from the plastic part of the MacBook that connects with the bottom half. Remove the screws on either side of the screen holding it to the brackets, there will be two or three on each side. Remove the sleep magnet on the left side of the screen. Remove the screws from the top, and carefully remove the tape from the back of the screen. Separate the miniature webcam and remove the old screen from the side brackets.
Install the new screen. You will go through the exact same process as before, but in reverse.

Replace the screws into the brackets and the sleep magnet on the left side. Secure the screen into the top casing and proceed with reassembly.

Free additional disk space on your boot volume. VM on a Mac requires free disk space on your startup disk. If your startup disk is nearly full, your Mac's performance will be degraded. Delete files you no longer need. Movies take up a lot of drive space, which makes them good candidates to delete.
Consider installing a larger hard drive in your Mac. If you cannot find enough files to delete on your boot drive, it may be time for a larger drive. It is best to consult with an expert or Apple Genius for this delicate process.
