Step 3 Battery

Tool used on this step:
P6 Pentalobe Screwdriver 2009 15" MacBook Pro Battery

Buy
• Three Pentalobe screws secure the battery to the upper case. They can be removed with this special driver.
• If you don't have a Pentalobe driver, a 1.5 mm flathead screwdriver can be used in a pinch. Be sure the head of your flathead screwdriver fits snugly across two of the five "points" of the screw head before trying to break the screw free, as a loose fit will easily strip the screw head.
• If the head of your screwdriver fits too loosely, find a bigger bit and file it down until it fits snugly before proceeding.
• You do not necessarily have to follow steps 3-7 to remove the battery in order to replace the hard drive. However, it is recommended to remove all power sources from electronics before working on them.
Step 4
• Remove the two exposed five-point Pentalobe screws along the top edge of the battery.
Step 5
• Use the tip of a spudger to bend back the finger of the "Warning: Do not remove the battery" sticker while you remove the five-point Pentalobe screw hidden underneath.
Step 6
• Lift the battery by its plastic pull tab and slide it away from the long edge of the upper case.
• Do not try to completely remove the battery just yet.
Step 7
• Tilt the battery back enough to access the battery cable connector.
• Pull the battery cable connector away from its socket on the logic board and remove the battery from the upper case.
• If you're installing a new battery, you should calibrate it as soon as possible.
Step 8 Hard Drive
• Remove two Phillips screws securing the hard drive bracket to the upper case.
• These screws are captive to the hard drive bracket.
• Lift the the retaining bracket out of the upper case.
Step 9
• Lift the hard drive by its pull tab and pull it out of the chassis, minding the cable attaching it to the computer.
Step 10
• Remove the hard drive cable by pulling its connector straight away from the hard drive.
Step 11 Hard Drive
• Remove two T6 Torx screws from each side of the hard drive (four screws total).
• You'll need to transfer these screws to your new hard drive if you're changing drives.
• If you are installing a new hard drive, we have an OS X install guide to get you up and running.
