If a MacBook Pro trackpad stopped clicking there are a few things you can try to troubleshoot and repair the problem.
This could be related to:
1. Failing (swollen) battery.
2. Wrongly adjusted trackpad screw.
3. Failed trackpad.
Let’s go thought the troubleshooting techniques step by step.
In order to check the battery you will have to remove it from the laptop.
Usually there are two or three screws securing it to the case.
These screws are Y shaped. You need a special tri-wing screwdriver.
You can try removing these screws with a small flat head screwdriver.
A Wiha 1.5×40 slotted screwdriver worked for me. It fitted into two out of three wings and I was able to remove both screws.
Unplug the battery connector from the logic board using a plastic stick or finger nails.
Remove the battery from the laptop and place it on a flat surface.
Check if the battery appears to be thicker than it should be.
When a MacBook Pro battery fails, in some cases it stars swelling.
If a swollen battery located inside the laptop, it pushes on the bottom side of the trackpad and it stops clicking properly.
Remove the swollen battery and test if the trackpads clicks normally after that. If it does, replace the battery.
If the trackpad still doesn’t click, even after removing the battery, try adjusting the screw shown on the following picture.
You’ll need a T6 torx screwdriver for that.
Turning the screw counterclockwise will loosen the trackpad.
Turning it clockwise will tighten the trackpad.
Place your MacBook Pro on one of the sides and continue clicking on the trackpad while adjusting the screw.
Find the position that works best for you.
If the trackpad still doesn’t click, even after removing the battery and adjusting the screw, most likely it failed and has to be replaced.
Here’s the removal and replacement procedure.
Carefully disconnect the trackpad cable using a plastic stick or finger nails.
Remove four silver screws.
You will need a small and sharp Phillips screwdriver. These screws are very small and easy to strip.
I’m using a Wiha precision screwdriver, Phillips #00.
While removing the screws, support the trackpad on the bottom with your fingers.
After all screws are removed, lower one part of the trackpad and slide it to the shown direction to separate from the palm rest.
Pull the cable though the opening in the case.
Remove the failed trackpad and replace it with a new one.
Start the re-assembly process with inserting the trackpad cable back in place.
You can guide the connector using a small flathead screwdriver.
Install the trackpad back in place.
Turn the MacBook Pro over and adjust the position of the trackpad.
Make sure all gaps between the trackpad and palm rest are equal.
After it seated properly, you can tighten up four silver screws on the other side.
It might be necessary to adjust the new trackpad screw as mentioned earlier.
Finally, install the battery back in place, secure it and connect to the logic board.
