Internal Keyboard and Trackpad not working
Hi
I have problem with my Macbook Air.
The internal keyboard and trackpad doesn't work anymore.
Keybord illumination is working fine and the power button also. If I plug in an USB mouse and / or keyboard both work fine.
I changed the cable from top case to logic board - still not working.
With the external keyboard, I did the hardware test - everything ok - and nvram reset - no change.
Some people told me about troubles with Sierra. Since yesterday I have the latest version - but still not working.
Does anybody have another idea to make the MacBook work again?
I need it!
Thanks, Stig

Is there a possibility to identify the problem?
Software? Diagnosis Subsystem?
Problem Update: After a SMC reset the keyboard and mouse it's working for ~ 1 minute (with interuptions).
Is the problem the USB controller?
Does anybody have any advise?

Hi @stigpfau , I'm having an exactly same problem with my macbook air 11" 2011. SMC did resolve the problem, but after few restart, it's froze again. It's been 5 years and I'm wondering do you have any long term solution?
