Keyboard only works when I put pressure between the keyboard/touch pad
The keyboard and touch pad quit working sometime ago, I found that if I push down on the case between the two they both work for a short period of time. Unfortunately doing this so much the case between the two is now somewhat bent down a little, I don't know if that is a big deal or just a cosmetic issue. Does anyone know if it is the keyboard that needs replaced or what, since it affects the touch pad as well. It still works putting pressure like I said but with it bent, I would like to fix the whole problem.
I had this same issue. For a while I was able to unseat the amber ribbon on the underside of the top case, gently rolling the ribbon back. I would then replace the ribbon into the connector. (Note: make sure to lift the ribbon locks on the the connectors before removing)
The issue was that the ribbon was made juuuust a bit short. After many many hours of high use, through the years the ribbon was not making full connection with the prongs in the bracket.
I eventually had to replace the lower case. The issue isn't with your keyboard, as that is the white ribbon and the amber is the one that the pressure is required for.
Anyone having this issue has two options.
1) Replace the ribbon. (Given all that it connect to, I don't advise it)
2) Replace the bottom case.
The repair guide that Mayer has included is spot on for replacing the top case.
