Why is my replacement top case flex cable too long?

I recently replaced the Top Case Flex Cable for my Macbook Pro (Model A1226). My keyboard and trackpad had been cutting out because of a common problem, so I thought this would help. It did initially (because it was a brand new cable) however I'm finding that the cable is too long, so once again doesn't lie flat (and therefore the battery pushes it, resulting in the case issue as I initially had). Could it be that the replacement part is in fact too long, or is it possible that there is blocking so the cable isn't seeding properly (and therefore makes so excess cable folds up).

Is this a good question?

Could be either one of your diagnosis. Could also be a swelling battery. Did you compair the new cable with the old one? Please give us the last three figures of your serial number and I will give you the correct part number.

Thanks for your quick response. Because of it I went back to check my work and made an embarrassing (to say the least) discovery. When replacing the cable, I had left a black piece (I don't know the name of it- kind of a square, with a square hole inside) from the previous cable. So, when I was installing the new cable, the new black piece went over the old one, making it double as thick, and making it so the cable had too much slack (again, sorry for the crude description) and therefore stuck out, giving it problems when the battery was installed again. So, now it isn't having issues. I'm just hoping I didn't ruin the cable itself because of my mistake. But if I did, buying one isn't too much of an issue (compared to replacing my whole top case or buying a new computer).

Thanks again. Hopefully somebody else can learn from my mistakes. Though I doubt anybody else was so careless!;)

Hi,

It would seem as though you have an a1260 cable which is longer then the a1226 cable. It should still work, the cable will just be bent a bit when the top case is put back into place.
