简介
Replace the Trackpad in your MacBook Unibody Model A1342.
-
Remove the eight 4 mm Phillips screws securing the lower case to the MacBook.
-
Slightly lift the lower case near the vent opening.
-
Continue running your fingers between the lower and upper cases until the upper case pops off its retaining clips.
Do the retaining clips have to be re-engaged when replacing the lower case?
Answering my own question, the clips re-engage when the lower case is correctly positioned. You can help them by gently pressing the lower case with your thumbs midway along the two short sides. When everything is correctly aligned the eight screw holes line up.
Rather than running your fingernail down the sides to free up the retaining clips, I found that using an old credit card, inserted about 1/4”, to run along the left and right side popped those end retaining clips right off with no problem. You may need to twist the card slightly when in the middle area to help pop those off.
-
Use the flat end of a spudger to lift the battery connector up out of its socket on the logic board.
-
Remove two 5 mm Tri-point screws securing the battery to the upper case.
"Tri-Wing Screws"? I don't see a "Tri-Wing Screwdriver" listed in the "Tools" section.

Just did it myself ;)

5mm tri-wing screw??
Its hardly that big. It certainly requires a tri-wing screwdriver much smaller than a 5mm tri-wing screwdriver - "Y1" is probably 1mm. The smallest I had was a 2mm tri-wing screwdriver and it just worked ok.
I think this and step 5 should be edited with better information.
The original iFixit guide described the step 4 screws as "tri-wing" but that is incorrect, it should say "tri-point" or "Y", and the required screwdriver diameter is 2 mm, not 5 mm. See this image:
http://en.wikipedia.org/wiki/List_of_scr...
The top row is tri-wing, the bottom row is tri-point, as found in this MacBook.
My tri-wing screws were black, 2mm and totally seized up. I had to break the plastic around the screw holes in the battery, remove it and then un screw them with long nose pliers. Needless to say they are now replaced with Philips screws.

A Y1 screwdriver emphatically did not fit mine - so in case it saves others buying a useless set of security bits like I did, you need a Y0, like this one: https://www.ebay.co.uk/p/tri-wing-y0-tri...
A small ~2mm flat-head screwdriver will fit across two of the points and have enough leverage to do the trick as well.
-
Use the tip of a spudger to carefully peel back the finger of the warning label to reveal a hidden Tri-point screw.
-
Remove the 5 mm Tri-point screw securing the battery to the upper case.
-
Remove three 3.1 mm Phillips screws securing the battery near the edge of the upper case.
When I re-installed the battery, I inadvertently ripped the ribbon between the Trackad ribbon and the battery ribbon. Be Careful!
"Remove three 3.1 mm Phillips screws securing the battery near the edge of the upper case".
Using the tools I bought from iFixit, I have got this far, no worries :)
The channels underneath/around these screws appear damaged and will not allow the screw to unwind and come out, therefore, the screws are "stuck". (This is by no means an indictment of the mini screwdrivers.) Any suggestions to help, because the replacement battery will not fit with these screws in place. Thanks.
These last 3 screws were a bit** to get off. One of them actually would not come out but I managed to slip the battery out anyways. Maybe it nudged just enough. Getting it back in was okay, just slid it under. Fit was snug, had to be careful not to break or crimp the ribbon in front of the battery connector, as Joel stated. Simply snipped a piece of the plastic tab from the old battery and stood it up in this spot and slid the battery down, this kept the ribbon from crimping. Only one of these last 3 screws that I did get out, did I put back in. Not sure why they are there as the tabs that hold them are enough to hold the battery. All other screws and battery connector worked like a charm. Replaced the cover, turn it on and Whala!!! Only got a message that said I needed to reset the Date & Time. Got it on the charger now, as new battery only had 75% charge, so fingers crossed it will recharge at a 100% and last longer than the old battery before it's next charge. Good luck everyone!!

Use the battery's plastic pull tab to lift and remove the battery from the upper case.
-
Use the flat end of a spudger to pry the trackpad ribbon cable connector up off the logic board.

Remove the four 1.3 mm Phillips screws securing the upper edge of the trackpad to the upper case.
I did this a while ago and I just wanted to add that my trackpad wouldn't click. As soon as I had the battery out I was stuck by how loose the set screw was (big flat torx head screw at the bottom center of the track pad). I had to play with the tension a little bit to get it an acceptable level of play but now my track pad works like new. Thanks iFixit and everyone who contributes to these guides!
My 00 Phillips head is doing nothing to remove the 1.3 mm screws that hold the trackpad in. Any suggestions? I also tried a 0 and a 000. Don't want to keep playing around in case it strips the screws, but they are really stuck in there...
Use a longer, sturdier screw driver. Either that or the screws have been thread locked in too tight at the factory. Apply more pressure. I mean, way more like, medium-hard pressure. if you don't care that much, apply hard pressure (If you're desperate apply even harder, just not so much it cracks the glass). Pressure is what holds the screwdriver in the screw, prevents it from slipping and stripping the screw! This is probably bad advice... I know.
-
Pull the trackpad away from its opening in the upper case to clear the two mounting tabs on its lower edge.
When remounting the trackpad, ensure you support it from the keyboard side when tightening the screws to ensure it's not crooked.
Highly recommend adjusting the T6 torx screw to ensure correct operation of the trackpad. Have the battery connected but not installed (so as to have access to the screw). Start up the computer. Test the click function at any time. Using very minor adjustments, turn the screw until you can see that the computer responds to clicks. When you are satisfied that it is working correctly, go ahead and shut down the computer and proceed with reassembly. It doesn’t hurt to give the unit a good clean while you are in there as this will avoid problems later, eg overheating due to dust blocking airflow etc. use an artists paintbrush and a vacuum cleaner or (gently) blow it away with (clean) compressed air. Some compressors have oil spray or water from condensation in the air, so use a filter in the line to avoid contamination.

My track pad was working intermittently and having a mind of it's own. Instead of going to a repair shop for a pricey fix, I followed this guide and removed the track pad, cleaned it up and hey presto it's fine now! Thanks for the guide, very easy to follow!!
How did you clean the track pad? Did you just clean the connector. I'm also having similar issues, my tack pad starts having a mind of its on randomly after few minutes/hours.
dirt can get trapped around or under the trackpad, causing touch malfunctions. removing this dirt usually fixes touch issues and maybe sometimes a click issue if dirt is under the trackpad
Does anyone have anymore information on the adjustment screw mentioned by John Tipton on Nov 6? I have made some adjustments to it and found tightening it actually locks out the ability of a USB external mouse from operating, and does not correct the problem of the internal track pad click function failing to operate. I suspect adjusting it properly may fix some of our track pad issues, but I have not discovered the proper way of making this adjustment.
My trackpad has stopped working, took the machine apart using above and there was some sticky mess that had been stopping the click from resetting.
Brilliant and much cheaper than the genius bar by using my 99p tri wing screwdriver!
Thank you. This guide is helpful, thank you for posting. Also thanks for selling the tools that let me do the replacement, I was able to replace the part with no hassle and the laptop is working fine again.
This guide is about the 5th or 6th guide I have used and every one of them is very well constructed and documented, I haven't been disappointed with any of them.
Up until this one I had made do with my own miscellaneous tool assortment, making do when I didn't have the exact driver bit or tool. The tri-wing screws in this one encouraged me to get the Pro Tech ToolKit Classic Pro Tech Toolkit and now I kick myself for not getting the proper tools sooner. All through my career as a Remodeling Contractor I maintained the attitude of using the 'right tool for the job'. Well, same holds true here.
Looking forward to my next iFixit job. Thank you iFixit.
Worked perfectly! Thanks much.
Great Step by Step easy to Follow Guide I am truly impressed.
I believe I might need special iTools for some of the screws ??
So I get a replacement trackpad, it was easy to replace however now I have to push really hard to get an active click (for some reason the right side works better than the left). I have taken the battery out to see if that was the issue (it was not, still didn't register a click with the battery out). What is the easiest way to remove the "setter screw", the T6 screw that adjusts the depth of the click. I need to replace it but I cannot for the life of me get it out of the casing.
It works great!!! i clean the trackpad!!!
Had an erratic pad on a users machine - looked like liquid ingress (coffee stains in bottom of case) Used 99% isopropyl alcohol, in a ziplock bag to soak the trackpad (without the cable) Worked the alcohol into the pad for a minute or two, removed, air dried for 15/20 mins followed by a quick blow with a hot air gun. Cleaned around the top of the case where the trackpad recess is too. Refitted trackpad, connector and battery and tested - trackpad is as good as new. Please follow precautions when using isopropyl alcohol, it is very flammable.
According to this page http://support.apple.com/kb/HT1651?viewl..., the 8 screws are not identical.
Can anybody tell me where each kind of screw is supposed to go?

They are all 100% Identical. You were probably looking at a different model, or Apple has entered the wrong information... Hey, It happens...

The screws on the Late 2009 are identical. The blue lock compound might make tightening some require a little more effort.

hi, i just got back from the apple store and they are really keen for me to upgrade to a new laptop since my battery is old and the screen is cracked, so glad i found ifixit i would love to upgrade this puppy! gonna make it a real sleeper! styler hall wrote about sticking 16 gb of ram in his a 1342 ? is this a simply mather of ordering 3 4gb sticks ?aslo i currently have 4 gb and would like to upgrade to 8 ( or indeed 16) does that mean i need to buy all new sticks or can i continue to use the old one and stick a new one next to it ?
thanks again mick van aar, perth western aus.

The A1342 will take up to 16 GB of RAM, however, there are only two RAM slots, so use two 8-GB RAM modules. Other World Computing (OWC) is a great reference source for info on exactly which RAM to use with which model; prices are usually much better on EBay though. Add an SSD from OWC and your machine will really scream!
I hope that helps!
