    • 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.

  13. 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.

    • 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.

I have a sensitivity problem with my new just installed Trackpad. Click works fine but the trackpad doesn't detect fingers the way it used to. For example if u use the tip of the finger (not the nail obviously) the arrow doesn't move at all but it works if u use the "fingerprint" part of the finger (flatter part). Any suggestions?

You probably need to slightly loosen the screw in that little triangle shaped groove by the bottom center of the trackpad. That will lessen restriction on the pressure sensor's range of movement so that it can detect slight touches.

Easy to follow, excellent instructions and photos. Apple considers this repair too difficult for the end user. The only thing that is difficult about it is having the right tools. Other than that, just focus. It took me maybe 30 minutes with the trackpad centering being the most time-consuming problem.

Great directions and very useful site! No surprises for this installation. Thanks!

The hex screw towards the bottom of the trackpad adjusts the sensitivity and “click” of the trackpad. This might need adjusting after installation.
