Will replacing the upper case fix my problem?
Two days ago, i spilled coffee on my macbook pro. I knew that I had to dry it out, so I tried to open it up to take the parts out, but I couldnt do that because I could not find a screwdriver small enough. So I then spread rice over the keyboard to soak up any moisture that might have gotten underneath. This seemed to work, because afterward my mac turned on and everything was like normal except for the trackpad, which was stuck. So I left the rice on it a few more hours, and after that the trackpad was working much better, though certainly not as well as it did before.
But a few of the keys no longer work on the keyboard, and I was wondering if replacing the upper case will resolve this issue?
