Edit Step 1 Lower Case  ¶

    • Seven 3 mm Phillips screws.

    • Three 13.5 mm Phillips screws.

Edit Step 2  ¶ 

  • Slightly lift the lower case and push it toward the rear of the computer to free the mounting tabs.

Edit Step 3 Battery  ¶ 

  • For precautionary purposes, we advise that you disconnect the battery connector from the logic board to avoid any electrical discharge. This step is optional and is not required.

  • Use the flat end of a spudger to lift the battery connector up out of its socket on the logic board.

Edit Step 4 RAM  ¶ 

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

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

Edit Step 5  ¶ 

  • 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.

I think something went wrong with mine at step 3.. after connecting back with new RAM.. Mac stopped working with battery... its working only on external power plug.. I rechecked it, googled it for SMC etc.. still no luck.. I did notice a small spark while removing for first time.. nothing after that.. even the LED indicator on the side with dots as battery indicaot is not working.. can someone help me please.. I'd say Step 3 is risky if it does these kind of things..

Hi, just wondering is it fine to put 4gb 10600 instead of the 8500 ?

It looks like you need a Phillips #000 screwdriver for the 10 bottom screws. I tried the #00 and it's too big. Good thing I bought a 23 piece precision screwdriver set or else I would have been screwed.

The 10 screws that hold tha bottom case take a #00 Phillips driver, if yours doesnt fit it's probably because it's cheaply made & not precise enough. The only thing that I needed a #000 driver for was the keyboard screws. They're so small they look like specks of dirt or sand. I stripped out 4 of them & now will need to grind the heads off with a Dremel/rotary tool. The other thing that sucks is iFixit doesn't have a tutorial for keyboard replacement!

iphonetechtips,

Perfect man!Many thanks!:)

Compare the short screws carefully before reinstalling them. The shouldered screws go in the holes on the front edge.

thanks twisk, I wish i would have read your tip before I finished putting the bottom of my laptop back together. I managed to get all screws in somehow, but one was in fact too-tight.

BTW, big big thanks to the Author: Andrew Bookholt. Just used this guide and my trackpad now works again.

xitxit2,

i too need a #000 for the bottom of the case -- i got the recommended screwdriver (#00) and unfortunately it's too big

Before I started removing any screws I took a piece of paper and drew the bottom of the laptop and put a piece of double-sided tape in the spot where each screw goes. That way when I took out the screws, I could put them on the tape so I knew exactly which screw went in which spot. I did the same thing for dismantling the inside on another sheet of paper, then a third sheet for the screen after getting the front glass off.

I use a similar technique: I print out the iFixit manual for the job, and Scotch-tape down the screws/brackets/cables I remove at each step next to the component descriptions. That way, when I'm reassembling, the bits are taped right next to the photo of where they came from.

adlerpe,

The colours you used for these circles are indistinguishable for colour-blind people. Please consider using something like the palette suggested by visibone: http://www.visibone.com/colorblind/

I'd use a Phillips #000 screwdriver also. The #00 can work, but if the screws are in really tight, it doesn't get far enough down into the screws to get purchase, so it will start to strip (and I agree that the screws are pretty soft). On mine, the screws for the fan were really tight, started to strip with #00, needed a #000 and quite a bit of pressure to get them to move.

why is step 3 necessary?

Just to disconnect any power source to avoid damages by short-circuits.

Removes the possibility of any current flow. This is especially important if you are trying to mitigate the damage to the circuitry due to a spill on a keyboard.

I'm thinking of ordering the spudger. I was thinking of order the heavy duty spudger... or should I just order the normal. Will either of the spudgers work for this DIY?

Once you have a set of spudgers, you will wonder how you ever went without them. :-)

Brian,

$@$@. Don't use an non-isolated screwdriver for this. I just shorted-out my battery :(

Lukas Besch, · Reply

You are absolutely right, never use a screwdriver on the logic board or any connector! Delicate use of fingernails or a credit card will get you through most situations if you lack a spudger.

Logan Bean,

How do you get that battery connector back on? Do you just press it in back in place after you're done?

Horace Chung, · Reply

yes. I usually plug it in before I screw it down so I can lift the battery a bit and have enough slack to be able to go straight down on the connector, otherwise it comes in on a bit of an angle, which can't be good (though not necessarily bad).

maccentric,
