Hello all, 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?
If it’s booting into Safe Mode but not your regular account it’s most likely a software issue. How well does it run in Safe Mode?
I don’t know if your system will accept 16GB RAM, but even if it does I believe 4GB+4GB RAM is more than enough because you’ll have bottlenecks elsewhere. And use the savings, add a bit on top, and get an SSD. That will boost your system performance more evenly. Specially if you want to upgrade to OS 10.9 and newer. I would get those, install a fresh OS, and transfer the data from the old drive. That would eliminate all software variables. And unless required by some software application that you need, I would stick with OS X 10.8.5 as I believe it will run best with your 6 years old configuration. And I have not yet seen computers ruined by sheer inland moisture. I live by the sea, in a very humid country, and the only humidity that killed the keyboards and boards that I received for repairing comes from lawn sprinklers, water cups, coffee, juice, and kids wanting to clean their parent’s dirty computer.
hello if moisture has damaged part of the shift key should be removed, or at least cleaned with a spray cleaner contacts. unless you have the expertise to do this you can use the keyboard viewer Mac OS X. choose Apple> System Preferences, click Keyboard menu, click Keyboard, and then select “Show Keyboard viewers, and emoji symbols in the menu bar.”
