Are there any news regarding a official fix for this problem? I have a Macbook Air 13 Mid 2011 and unfortunately I have the same problem with the "qwertyuio" buttons row. It seems a problem with the software (maybe a bug?), because when rebooting the mac usually the row never works ... To run the keys, I have to press repeatedly (and randomly) all the keys from "q" to "o" many times. Once they take the input, the keys work correctly until the mac spend some time in standby...
Do you have any solutions or tips? I've already checked, opened, cleaned the mac and internal parts (battery is ok, not a single crumb or spill) and tried all the fixes that I could find on the internet. But unfortunately the problem continues to be there! I would not want to change all the keyboard then find out that the problem is always there :(
Thank You and regards!
Hi, I'm writing some sort of update... Maybe I found my problem!
Yesterday I opened the Mac, removed the battery and cleaned the logic board with some ethanol... Until I realized that it was not the logic board causing the issue with those keys but the one-way-pin starting from the keyboard, goes from the trackpad and connects everything to the motherboard.
I cleaned these three connectors (attached picture) : https://postimg.org/image/5e6rzygwr/
And now, It works!
My considerations? Perhaps, the old battery was inflated a bit and pressed abnormally on the trackpad, where the two connectors (keyboard + trackpad) reside. When I changed it a year ago, I probably didn't notice this difference!
So the fix is: If you have a keyboard problem and you have a macbook out of warranty, I advise you to clean everything sparingly (pins, connectors etc.) before replacing any hardware part! ;)
I hope I've been helpful. Regards
