key is working intermittently MBP 15"
Hi, later this days i noticed that my A key is working intermittently, i removed the keycap and everything seems to be okay with the rubber cup, I've dual boot with Mavericks and Yosemite and it happens on the two of them so i assume it must me an hardware problem. Anyone else experienced something like this before that can share some tips in order to make it work without replacing the entire keyboard? I've been messing around with the key but no luck so far.
MacBook Pro6,2 (Mid 2010)
Thanks in advance
