Title:

Internal Keyboard and Trackpad not working

Text:

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

=== Update (11/12/2016) ===

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?

Thank you.

My Macbook is working fine currently.
