              Battery Connection

Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.
It is useful to pry upward on both short sides of the connector to “walk” it out of its socket. Be careful with the corners of the connectors, they can be easily broken off.

Step 7

Use the attached plastic pull tab to remove the battery from the upper case.
If you’re installing a new battery, you should calibrate it after installation:
Charge it to 100%, and then keep charging it for at least 2 more hours. Next, unplug and use it normally to drain the battery. When you see the low battery warning, save your work, and keep your laptop on until it goes to sleep due to low battery. Wait at least 5 hours, then charge your laptop uninterrupted to 100%.
If you notice any unusual behavior or problems after installing your new battery, you may need to reset your MacBook’s SMC.

Step 11

If necessary, carefully dislodge the edge of the trackpad closest to the keyboard from its recess in the upper case by pushing it away from the brackets attached to the upper case.
Carefully push the trackpad connector and cable down through the slot cut into the upper case.
It may be necessary to use a spudger to help get the trackpad connector past the edge of the logic board.
Once the cable has been completely pulled through its slot in the upper case, pull the trackpad away from the outer edge of the upper case and remove it from the machine.

Step 12

If you are installing a replacement trackpad that didn’t come with the attached flex cable, you’ll need to use the cable from your old trackpad.
To remove the flex cable from the old trackpad, first flip open the latch on the ZIF connector, opposite the cable. Then, apply a little heat from a hair dryer or iOpener to soften the adhesive securing the cable to the trackpad, and carefully peel off and remove the cable.
When installing your new trackpad, routing the cable through the upper case and past the logic board may be difficult. It is helpful to use the tip of a spudger to guide the connector past the logic board while pushing the cable through its slot in the upper case with your other hand.

any tips on adjustment of the height screw?

Athaariq Ardiansyah Ramadhani - Oct 28, 2016

don’t turn the screw too much, or you’ll destroy your trackpad

Steven - Jun 26, 2017

I had a lot of trouble getting the new trackpad to work. The left side of the track pad (about 2cm) was responsive. The rest of the track pad was dead. I played with the torx screw to adjust the click pressure and it had no effect. I cleaned all the gunk out from around the perimeter of the trackpad when it was removed. I tested without the battery in place to ensure that battery pressure was not the problem.

The actual hardware remove, reinstall took about 15 minutes at most and was very straight forward.

The trouble shooting has been the tough part.

Thomas Reese - Dec 20, 2017

I replaced the track pad successfully, but it did not fix the problem I was having. When I want to drag and drop a file, I really have to push down on the track pad hard to hold on. Its a little bit better with the new pad, but I still have a hard time with the lower left corner of the track pad grabbing stuff. Anyone have any ideas of what the issue could be?

Thomas Reese - Jan 7, 2018

I am assuming it was the battery. Put in a new one and now no issues.
