Keyboard Intermittently Non Responsive - Top row of Qwerty only
in the past three months my MacBook and has developed an intermittent problem which has become more frequent.
I now I have to either use my Bluetooth keyboard or dictation!!
It is just the top row of letters, QWERTYUIo... P works!
If I move the keyboard problem, if I type repeatedly and seemingly fill the keyboard buffer the problem goes away.
I have taken my MacBook air to the genius bar, and after running diagnostics they found no hardware problems.
My Mac is running OS X 10.10.5
It's a mid 2011 13 inch 1.8 GHz Intel core I7, with 4 GB of DDR3 RAM
I've tried resetting the PRAM ram, no luck. Similarly the SMC reset.
Everything else runs fine, so I'm reluctant to go buy new machine when this feels like it's a bug.
If anyone has any suggestions, hints or tips - I would be eternally grateful!
