My laptop wouldn't believe the battery was new until I reset the SMC as well ( http://support.apple.com/kb/HT3964 ).

once the battery is replaced with a new one, should it be drained? or charged full?

Apple is currently replacing battery for mid 2009 macbook pro for $129.95 no labor. If you've got a store nearby, not a bad option to get them to do it right and test to make sure battery, and not have to worry about the tiny screws. I've received two different reports however - 1 genius told me they could replace while I wait in about 20 minutes. Another told me I'd have to leave it over night.

Perfect! I didn't want to wait for the Tri-wing screwdriver to ship, so I gave it a try by wedging a FH 1 in between two of the wings. It worked well to unscrew, but you must be very careful when resetting the screws that hold the battery. If you get them started with your finger (a little pressure with your thumb pushing straight down will get the job done) then you can do a few final turns with the FH 1. If you try to start resetting the screws with the off-center-FH1-workaround, you will strip the screw! Keep the screws centered and don't force anything.

worked like a charm. my old battery had bulged and made it so that the track pad would not click :-( replacing the battery did the trick.

My local Apple Store wants $179 plus tax to change this battery, AND I have to leave my laptop for "a couple of days." This is one store that clearly doesn't get it (Cherry Creak Mall, Denver). Thus, a DIY fix is mandatory... but, they won't sell just the battery.

iFixit sells the battery you need for $119 (http://www.ifixit.com/MacBook-Parts/MacB...), and once you get it, doing the replacement shouldn't take more than 30 minutes, even if you've never done a repair like this before.

Taylor Arnicar,

This is really easy if you got right tools, just tested and in few minutes I changed my old battery with new :)

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.

Where can I buy 5.5 mm tri-wing screw and 13.5 mm tri-wing screw ?

gansodesoya, · Reply

I have the same question? Where can you buy new screws. Apple put in these rediculous tri-screws.... The short one went in crooked and jammed. I couldn't get the long one back in at all, not sure why, but it's not catching a single thread.

My 2nd question is, what the alternative if you can't get the screws back in (e.g. some kind of tape). With only one screw only half way in and jammed, the battery doesn't seem to be moving around, so I think I'm ok, at least for now.

Mike Mullally,

similar issue here, I'd like to buy these bolts new. and it would be even better to buy new ones but with a philips head, not a triwing head. please let us know. thanks.

Manuel Torres,

Still no answers on this?

You can get the tri-wings from ifixit directly - http://www.ifixit.com/Store/Tools/Tri-wi...

or get the whole kit (like I did - it's excellent) - http://www.ifixit.com/Store/Tools/Pro-Te...
