Image 1/1: Three 13.5 mm (14.1 mm) Phillips screws.
  • Remove the following ten screws securing the lower case to the upper case:

    • Three 13.5 mm (14.1 mm) Phillips screws.

    • Seven 3 mm Phillips screws.

Step 1 (technically step 9 - replacing the base plate) Apparently one of my screws was a micron or two smaller than the others. This screw belongs to the hole above the optical drive, which is also apparently a couple of microns smaller than the others. It took seven attempts to figure which screw had originally been in that hole; all the other screws were too large, but fitted perfectly everywhere else.

Bizarre much?

It might be a matter of how the screws are driven in, and not that they're slightly different sizes. When I reassembled my MacBook, a couple of the screws, including the one over the optical drive you mention, were hard to drive in and jutted up a little bit instead of sitting entirely flush. Swapping screws didn't help. The solution was to unscrew them and drive them in at a bit of an angle - perpendicular to the slightly curved surface of the back plate where the screw holes were, instead of fully vertical with respect to the ground the Macbook is sitting on. Doing it that way, the screws were easier to drive in and they all ended up flush in their holes. Didn't matter which screws they were. (I swapped a few around just to check after reading this.)

I discovered a great way of organizing the screws. I used an ice cube tray and added the screws in order, keeping the different kinds together. So when it came to reversing the steps, the screw order was an added control step to returning everything in its place.

Great advise! Love it! :)

I used to do that and that worked really great until I bumped it by accident and the entire tray went on the rug! I spent the next day sorting things out.

Now I use these:

The lower ones 50 to a package. I mark them w/ blue tape. Often if it's part like the fans, or the optical drive I'll tape the screws into/near the holes where they belong. I did this a lot especially w/ the bottom screws from MBPs until I'd done so many I knew exactly where the longer ones went.

Richard Sato -

I wrapped the screws in a piece of blue masking tape and wrote the number on the little pouch I made. Then I stuck the blue tape pouches on the underside of the case bottom in order.

Roscoe -

I take double-sided tape, put that on a piece of paper, stick the crews to that, and label them.

Best I've found is a bead sorting tray. They're like $5 at Wal-Mart and they have a lid that seals up and won't let them jump between containers.

I take a sheet of paper, pierce the screws through the paper, take a pen and box the screws and write out what step they belong to.

@Will, in my case I had the same result as you did. As a reminder to myself the next time I need to open the computer, I put a dot of white paint on those two screw's head and a very, very thin ring of white on the very edge of each hole, that way I'll know they go into those two holes.

Actually the four screws on the bottom were not threaded all the way up. I didn't check to see if the thread gauge was the same on them, but it wasn't until I had about four screws out (I didn't take them out in the order that the bottom all came out first) that I noticed a difference. I then took out the rest of the bottom ones to see if they matched the two that were already out that weren't threaded to the top. They did. So I went under the assumption that those were all bottom screws and when I put it back together everything went fine with no resistance.

So there are three types of screws: Four for the bottom, three long ones as indicated and three others that might be slightly smaller than the bottom ones.

Although its more than a year since your contribution, I thought you might be amused to know that it is not just that the screws go in more easily when at an angle, Apple actually drilled and tapped the holes at a 15% angle. I too had tried to drive them in straight. An Apple "genius" - I was in for something else - clarified the design for me. It was done so that the screws lay flush on the angled part of the lower case. Nice design, but since Apple encourages DIY memory and drive changes, they could have mentioned this little ... trap.

I have installed the second drive with ssd 840 evo, but when I try to copy the file from the new drive to the main hd this in not allowed (errore -36)

To my knowledge you can't transfer a single file more than 4gb. I advise compressing to a bunch of rars to split the file size and moving them individually

Hey everyone, here's the very best way to PERFECTLY organize your screws AND keep track of the order of the procedure: Get a piece of plain corrugated cardboard and a pen (I like using a Sharpie). For EACH step of the disassembly, draw a simple diagram of the layout of the computer on the piece of cardboard, with dots or Xs where the screws are located. Right after you remove each screw from the computer, poke a hole in the cardboard in its corresponding diagram position with your screwdriver and place the screw in that hole. If there are other non-screw related parts to be removed, you can add notes below each step diagram to remind you of where they go or how they should be placed. This cardboard method is great not only because your screws will not go flying or get mixed up by accident if bumped, but each screw goes EXACTLY back where it came from and you can keep the cardboard as a template for future use if necessary!

These instructions worked great for me. I ordered a replacement battery from Key Power (on Amazon) for my 15" Macbook Pro (mid-2010). Cost was $74 shipped.

Battery came with 3 different screwdrivers to help with installation. I just needed the one size though, since my 2010 seemed to use all the same size screws.

During re-assembling (put the screws back in), it is important to note that the 3mm threaded holes are not completely vertical, but bent a little bit such that the hole direction is rectangular to the tapered surface. The force of the screwdriver must point towards the direction of the hole. Otherwise the screw gets jammed

There is a FOOLPROOF WAY TO ORGANIZE ALL SCREWS and other parts removed.

Print the repair guide.

Yes, the actual photo of the bottom of the laptop with the circles around the screws.

When you remove the screw, tape it to the photograph.

You will tape the screw to the exact location that you just removed it from.

Same thing with any part you remove.

Thanks Splash!!! I used your suggested method, and it was perfect: kept all my screws, and i was able to, very easily, put them back in their correct place. I greatly appreciated your feedback. Thank you for sharing!!

Tommy Kedar -

Thank you!!! This worked fabulously - even the I.T. people at my workplace were excited as they never thought to do that before. Replacing the battery took about 10 minutes!

nclarke36 -

Worked like a charm! Took less than 20 minutes.

It's Oct. 2015, and the fan cost me about $10. it was the same brand/model...

SUNON MG62090V1-Q020-S99 .


1- no T6 screwdriver- was careful using needle nose players to loosen 2 screws protruding up, then use a small phillips to push real hard into the T6 slots, SLOWLY turn , also used a small flat head screwdriver (for eye glass repair) was able to grab thread on T6's, made a small mark with screw driver across the top so I could see when it started to turn.

2- no spudger -made one; cut a little strip 1/2" x 1 1/2" of plastic. couldn't get it to slide under plug, there's an edge where plug fits. so lifted old fan out, pulled upward on the plug it popped right out with very little effort. I used my home made spudger to push the new plug into place.

3- download free "Macs Fan Control" This is how I was alerted to the fan not working in the first place. Program shows temperature of all key components in the computer.

cheers- Durango CO!

Watch the video first, read the entire tutorial and all the comments before you start, and spread a white towel on the floor so you can find screws when you drop them. Watch this first --

Please be aware that you CAN do this replacement with MUCH LESS work. I successfully replaced a trackpad (TP) in this model WITHOUT removing a lot of what is described here. I think i mainly removed the logic board (LB) anchor screws along the TP side and was then able to lever up the LB just enough to get the cable unplugged and snaked out. Followed the reverse and done. Maybe not for all, but it worked for me. // Re screws: i print out the images here of the multi-screws locations and then tape the screws in place on the print-out.

Image 1/1: Remove the lower case and set it aside.
  • Using both hands, lift the lower case near the vent to pop it off two clips securing it to the upper case.

  • Remove the lower case and set it aside.

After pulling out the lower case and put it back on, the lower case doesn't stick well with the left clip. What should i do now?

Does anybody know the size, measurement, or part numbers for the two screws mentioned in this step? I'm having a hard time finding them even through the most determined googling. The one closer to the three cables is fairly long, and the one closer to the logic board and speaker assembly is short. That's about all I know...

I didn't even have to replace my daughterboard -- I ordered a used one, but simply "reseating" (removing and attaching it again) the ribbon cable to the daughter board fixed my problem that the WiFi and Bluetooth card was invisible to the OS.

Thanks anyway for these great instructions! Without them I hadn't even thought about that the WiFi functionality was on a daughterboard... I thought other than in most "Windows laptops" that functionality was integrated into the main board.

Ralf Bergs - Reply

Excellent guide! The whole thing took me about 30 minutes and as soon as I turned on my mac again the WiFi worked perfectly.

Yannick Streit - Reply

I replaced both the card and the ribbon cable. Still get the message that there is no WiFi device installed. 15" MBP, mid-2010. The Bluetooth and Ethernet still work. But it is very inconvenient not having WiFi. Any thoughts on what else to try would be appreciated.
