Edit Step 3 Battery  ¶ 

  • Remove the two 5-Point Pentalobe screws along the top edge of the battery.

  • You do not necessarily have to follow steps 3-6 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.

  • It is useful to twist the spudger axially from beneath the fan cable wires to release the connector.

  • The fan socket and the fan connector can be seen in the second and third pictures. Be careful not to break the plastic fan socket off the logic board as you use your spudger to lift the fan connector straight up and out of its socket. The layout of the logic board shown in the second picture may look slightly different than your machine but the fan socket is the same.

Edit Step 21  ¶ 

  • Grab the plastic pull tab secured to the display data cable lock and rotate it toward the DC-in side of the computer.

Image #1

Edit Step 22  ¶ 

  • Pull the display data cable connector straight away from its socket.

  • Make sure to pull the connector parallel to the face of the logic board, not straight up from its socket.

Image #1

Edit Step 25  ¶ 

  • Carefully lift the logic board assembly from the left side and work it out of the upper case, minding the port side that may get caught during removal.

  • Do not entirely remove the logic board yet!

Edit Step 26  ¶ 

  • Lift the logic board enough to gain clearance and use a spudger to pry the microphone up off the upper case.

Image #1

Edit Step 27  ¶ 

  • Slide the logic board away from the port openings and lift the assembly out of the upper case.

  • Before reinstalling the logic board, it is easiest to press the microphone down into its housing in the left speaker to keep it in place.

  • If your microphone is still inserted into its void in the left speaker housing, use the tip of a spudger to lift it out.

Image #1

Edit Step 29  ¶ 

  • Remove the small strip of tape covering the left speaker connector.

Image #1

Edit Step 30  ¶ 

  • Use the flat end of a spudger to pry the left speaker connector up off its socket on the logic board.

  • Pry up from beneath the wires.

  • Remove the eight Phillips screws securing the heat sink to the logic board.

  • Keep track of the springs under each of the screws as you remove them.

  • Do not press down on the screws excessively while breaking them free.

Image #1

Edit Step 35  ¶ 

  • Carefully lift the heat sink off the logic board.

  • If the heat sink appears to be stuck to the logic board after removing all eight screws, it may be helpful to use a spudger to separate the two components.

  • When reinstalling your logic board, don't forget to apply a new layer of thermal paste to the face of each processor.

Image #1

Edit Step 36  ¶ 

  • Release the tabs on each side of the RAM chip by simultaneously pushing each tab away from the chip.

  • These tabs lock the chip in place and releasing them will cause the chip to "pop" up.

  • After the RAM chip has popped up, pull it straight out of its socket.

  • Repeat this process if a second RAM chip is installed.

To reassemble your device, follow these instructions in reverse order.

Question: why do you remove the battery? According to Apple's official manual, this is not required (not for the mid-2009 and not for the mid-2010 15-inch MacBook Pro) - see pages 37 ff:

I'm interested by your experience.

Did you have removed the optical drive without removing the battery ?

I'm just in this step now and if it is possible I would proceed like you because removing the battery void the warranty (and there is a sticker).

Thanks in advance.

Looks like my note to step 3 appears on all repair guides that have the same step. I meant that in the context of the hard drive replacement only.

Did you have removed the optical drive without removing the battery ?

I haven't yet done anything, waiting for my MacBook Pro 15 inch mid-2010 to arrive.

I missed the notes and went ahead and purchased the 5 point driver for the battery before I realized it was not necessary.

I've edited the repair guide to remove the section on the battery, but I don't have the points to approve the changes.

Chris Davis,

Please note - the step about removing the battery is part of a pre-requisite guide, that is used for many of the guides, most that do require removal of the battery. Also, working inside a disassembled laptop with the battery still connected risks damaging/shorting out very expensive parts.

Absolutely. To be clear -- ALL of the above discussion is ONLY in reference to replacing the hard drive.

Chris Davis,

I replaced a hard drive in a MacBook Pro of an earlier model than this without removing the battery. The hard drive wasn't right. It only worked at about half speed, and I had to replace it once more. The second time I removed the battery and all went well. The recommendation by the iFixit staff to remove the battery before working on electronic equipment is a good one.

Removing the battery is not necessary for the hard drive removal/replacement procedures.

My T6 (appears to be same screw driver you have - $6 on amazon for 20piece set) did NOT fit int he battery screws...not sure if I had the wrong screws or what, but I went ahead w/o battery steps and it was pretty easy.

Anthony Ettinger, · Reply

I also noticed that the new SDD (from crucial) didn't have the 4 screws, so I had to move those off the old HD and onto the new one.

Anthony Ettinger,

Top left screw in this picture isn't a torx screw, and should be left in place. The screw you want is a bit further down than the one circled.

Good catch! It's fixed now.

Andrew Bookholt,

Could not figure out what this step was telling me to do. The warning made me very cautious. Never got the board out because of this step. (Then I broke the subwoofer, but I can live with that.)

Not sure what this is supposed to do. I tried to gently pry subwoofer off but it broke. :-(
