    The trackpad cable can also be of a different type where you pull the tape on it

    If you are replacing an old battery with a new battery, and the trackpad cable goes “under” the battery from the trackpad connector to the other side of it (instead of the trackpad cable going “over” the battery from its trackpad connector as shown in the provided image), then you might instead see a trackpad connector that has a loose tape on it. If the trackpad cable goes “under” the battery then it is possible to skip this step. It is not necessary to pull the tape. Note that I had an A1502 MacBook Pro laptop and was replacing its A1493 battery, it had the trackpad cable going “under” the battery, so I skipped this step and was still able to successfully replace the battery.

  2. Lift the trackpad cable up off the battery to separate it from the adhesive securing it. Be careful not to damage the cable. If it doesn't peel up easily, apply a little heat from an iOpener, heat gun, or hair dryer to soften the adhesive, and try again.

    • If you are installing a new trackpad cable, be sure to fold the new cable to match the shape of the old cable. The new cable will appear to be too long if it is not folded.

    On the picture above, it looks like, that the CIF cable for the keyboard, located right to the trackpad cable, should also be separated, but this is not necessary. You can leave it attached.

    What helped release the cable was to place the body of the spudger under the cable and rotate it upward as I gently pulled it down to release the cable from the adhesive. It may not have been necessary, but it did help.

    I did this after reading your comment and it worked incredibly well!

    For people having keyboard or trackpad issues:

    If you followed the disassembly photos you may have lifted the the tap on the ZIF connector in Step 18 image. Note the lifted “tape” below the thumb. This may release the ZIF Connector and cause keyboard issues. Make sure the black retaining bar is in the down position on the ZIF Connector.

    Also, check the ZIF connector in Step 19 and 20. The Black plastic retaining bar MUST be in the “up/open” position to remove and reinstall the ribbon cable.

    Overall, I really enjoyed this project and it was a complete success but this step is the one spot I came up short. I forgot to flip the retaining tab back down when I reassembled and I got a totally unresponsive keyboard and trackpad before I opened it back up and realized I had forgotten this tiny but crucial step.

    I also forgot to flip the ZIF connector. Thankfully my trackpad worked after.

    Make sure to flip the ZIF connector before putting the trackpad cable back, too.

    I did not remove this retaining clip for fear of not getting it plugged in again then just carefully folded it back to clear battery instal

    Peter Stoll - Reply

    This was the most challenging part of the installation. Putting this tab back, it's so fragile and difficult to put back. I thought it was going to get damaged but it worked.

    Gaetano Daidone - Reply

    Like Peter, I just folded it back a bit and had care to keep it out of the way. I think it is much better than the risk involved with taking it out.

    All in all it found it a bit less difficult than I expected - As with all the work I have done on different Apple products: Slow and careful work and following the instructions - including all the comments - seems to be the best advice.

    I have a semi responsive trackpad and an unrecognized keyboard. Any suggestions?

    Daniel- remove and put back again the cable on the ZIF connector, making sure it is pushed all the way in before closing the retainer clip. May have a partially reinserted cable.

    This was the most difficult part for me.In frustration, I thought I had a bad cable so I bought two new ones and still was not successful.So I skipped the whole thing and bought an external wireless keyboard which I have been using till now.Recently, my LCD screen cracked and I am about to replace it. So, I now have another opportunity to open my laptop and try fixing this step again.This time I will read users comments before attempting another go.Please if anyone have additional useful tips for this step, kindly post a comment.I should be fixing my laptop in 2 weeks.Thanks!

    One thing to know about the tape that you have to remove is that it has "arms” that wrap around the cable just beyond the connector. If you bend the cable toward you you can see these. Remove/bend them so that they are pointing ‘north” and then pull the sticker.

    Michael Gorman - Reply

    The “flip up” tab was hard to see for me but once my 7yo confirmed it was up, I slowly moved the cable into the slot using my fingers (to avoid bending/breaking anything, thanks to comments I read), staying perpendicular. Once it was clearly in, I confirmed it was fully seated with a toothpick (a gentle tool for delicate parts). If worried, take zoomed in pictures straight from above, that way you will know what it should look like when reassembling.

  4. Pull the trackpad cable straight out of its ZIF socket on the trackpad control board. During reassembly, make sure that the retaining tab is in the up, "unlocked" position before you insert the cable into the socket.

    With all due respect, step # 19 and 20 pics shows the ZIF socket on the trackpad board, not the Mac logic board, I think...

    See step #17 which seems to be correct. There is an inconsistency in the guide.

    Just to be sure...

    This was the most difficult step for me. It was hard to locate the retaining tab on the ZIF connector and the trackpad cable had some adhesive on the bottom of it and it was difficult to remove from the socket. Be patient….

    Gary Bain - Reply

    I skipped this two steps (19&20) , just bent the flat fable when taking the battery out.

    Aleš Smokvina - Reply

    This does look the most frightening part of the process, that connector looks really flimsy. Is it ok to just bend it back and leave it connected as suggested?

    Jack Sukerman - Reply

    This is the only step I skipped, as Gary Bain mentioned above there was adhesive which made it difficult to remove, and it’s probably the only step worth skipping.

    Can you buy replacements for this trackpad control board? They dont seem to come with new trackpads.

    Rachel MacLeod - Reply

    The ZIF retaining tab is a tiny black plastic bar. Pull the trackpad cable HORIZONTALLY out of the socket.

    Unfortunately, i didn’t notice that there was a retaining tab, so i damaged my ZIF Connector. I ordered a new one from amazon. I followed the procedure and did it in the “correct” way. Anyway trackpad and keyboard won’t work. Can you help me?

    Andrea - Reply

    I removed that cable and not sure that I put it back properly. The trackpad and keyboard are not working. I might need to order a new trackpad cable and try the process with the new, Can anyone help?

    Thank you

    I broke the tiny plastic clamp on the ZIF socket and that, to my understanding, is why the ribbon cable is not connecting properly (so neither keypad nor keyboard are connected). I wonder if I can buy a replacement somewhere for that clamp or the socket as a whole.

    Ghassen -

    Hi Ghassen, I too just broke the plastic clamp on the ZIF socket. What did you do to repair it? I’m pulling my hair out looking for a solution!

    David O'Brien -

    "straight out" in this case is away from you and horizontal, not straight up! I tugged on the cable a bit harder than I'd like to admit before realizing my mistake, although no damage seems to have occurred.

  5. Remove the single 3.7 mm T5 Torx screw securing the battery board to the upper case.

    Before continuing, draw around the outside of the existing battery with a pencil to make a template ready for when installing the new battery. It means when you get there, the new battery can be installed perfectly in place and you will not have space problems when trying to reinstall the speakers during reassembly.

    when installing new battery it is better to start with this step and secure the battery control board first with the screw. This is needed to align the battery plug with the jack on the mother board, then glue the rest of the battery back.

    FYI this was a T4 on my system

    When aligning the placement of the battery, on my second attempt, I used a sim card removal pin (a paper clip would suffice) to align the battery board hole with the screw hole underneath. Unfortunately on my first attempt I inadvertently stripped the threads a little. Luckily there was just enough threads to hold
