Hey Guys,
Suddenly, my Macbook Air mid 2012 model number a1466 has had this trackpad issue. Basically as mentioned in the thread the left click is not responding, most of the time it will work once in about 100 clicks, it randomly highlights text when I attempt to scroll, and drags text etc., however gestures still manage to work. If it was a software issue, one would know after plugging in an external mouse, which at the moment has saved my child. The funny thing is the button still clicks perfectly and the touch gestures work but the click and tap to click doesn't and this leads me to believe a component or circuit has just failed due to use.
I have attempted all the SMC + PRAM resets, attempted a hardware test and I even did two full clean installs of OS X Mav just to be sure, but obviously this is a hardware issue which is not being detected by the machine as the hardware itself is not 100% broke. I have tried every fix and read every thread. I am a computer and smartphone technician myself, but never actually came accross this kind of issue and after researching this, I am actually appauled that Apple has not addressed this issue in a professional expected manner. I have ordered the part to fix the trackpad along with it's flex cable that connects it to the motherboard as in my opinion and the opinion of many others, this is the only viable permanent fix.
This swollen battery excuse is for a very small minority. The tightening of the screw below is also understandable but to conclude what I have seen with my machine and read throughout a lot of threads the only fix for this is replacing the trackpad and/or it's flexcable. It is one of the easiest fixes actually, which can be swapped out within about ten minutes.
There are many tutorials online so if you are one of us that is experiencing this issue, calm down. It will be ok 🙂. Unlike everyone else on this thread though I have been using my trackpad for at least a year now and I am only experiencing this issue all of a sudden. I do feel for the people who have no knowledge of being able to fix this. I will write back on this thread to confirm if in fact the new trackpad sorts this issue out. I am convinced it will from experience of replacing components on other Apple products.
I hope anyone stumbling onto this thread has found comfort in what everyone is saying because your MBA is not doomed!!! 🙂🙂
