Apple MacBook Pro 17 – How to replace the Hard drive of Apple MacBook 17 – Laptop repair and service


Apple MacBook Pro 17:  HARD DRIVE REPLACEMENT PROCEDURE 
Remove the following ten screws securing the lower case to the upper case:
Three 13.5 mm Phillips screws.
Seven 3 mm Phillips screws.
Wedge your fingers between the lower case and the vent, and lift upward to release the clips holding the lower case to the upper case. Remove the lower case.
Whenever working near the logic board, it is always wise to first disconnect the battery to avoid short circuits. If present, grab the plastic tab attached to the battery connector and pull it toward the front edge of the device. For Late-2011 models the battery connector will not have a tab and is simply a plug that inserts straight down into the motherboard--to remove pry the plug straight up. If the plastic tab is missing, use a spudger to pry the connector up from its socket. Pull the tab parallel to the face of the logic board.
Remove the two Phillips screws securing the hard drive bracket to the upper case. These screws are captive to the hard drive bracket.
Remove the hard drive bracket from the upper case.
Use the hard drive's pull tab to lift it out of the upper case. Don't try to completely remove the hard drive just yet! Its cable is still connected.
Pull the hard drive connector away from the body of the hard drive. Remove the hard drive from your MacBook Pro.
Remove the four T6 Torx screws around the outer edge of the hard drive.
If desired, peel off the plastic pull tab and transfer it to your new hard drive.
