Unresponsive keyboard & trackpad
MacBook Air "Core i5" 1.7 13" (Mid-2011)
This MacBook air was working fine. No water or other liquid spilled. Just out of the blue, the keyboard and trackpad just became unresponsive.
It gets a connection with bluetooth device dialog window, and that works externally with USB with no problems.
Now in the system preferences you can't change anything, only gives you the bluetooth options?
There are no options to change any setting, such as ignore trackpad etc in universal access etc.
SMC & PRAM do nothing, Safe-Boot, does nothing, its in all users, so its system wide
Tried upgrade to Yosemite, no change.
Checked all hardware, removed battery checked cables and connectors all looks fine. Can't see any damage scratches or pollution?
So my next step will be erase and clean install, not from Time machine back up to see if that helps.
My question:
How can this happen, and why does it get stuck on the bluetooth dialog window and is there a way to re-activate missing preference settings such as mentioned above.
It puzzles me how that can just disappear. Any info is welcome
I'll keep updating this as far as it goes, I did come across a few similar situations online, but not with clear details on my question.
Thanks in advance
Daniel
Is this a good question?

Yeah so clean OSX instal did help for a period of 10 seconds than again Bluetooth connect dialog came up and no way around it,also in preferences still no option to change ignore trackpad option to de select…
Will probably try change keyboard/trackpad and see what happen.
