Shift key randomly ACTIVATING.
My MBP 7.1 RECENTLY froze after spending time in A VEry humid place(canyon lands of southern Brazil). When I restarted, it would only boot in safe mode. I figured something was wrong with the keyboard, so I replaced it and cleaned the inside, thinking some of 5 years' accumulated dust may have been partially responsible. After successful installation, computer was still slow(it was not so slow before I upgraded to El Capitan, seems i need more ram). Unfortunately, morning come, the same problem with the shift key had returned.
Is there a software fix for this?
Is this a good question?
