I have a strange issue with my early 2015 13" Macbook pro. The keyboard and touchpad no longer works during boot or in OS X. I can't, for example, use the internal keyboard to boot from USB, but have to hold down option on an external USB keyboard to select startup disk. Even the caps lock key light doesn't turn on when pressed. However, I can use the internal keyboard to do an SMC reset and both touchpad and keyboard works fine when booting Linux from a USB stick. External mouse and keyboard also work fine.
The computer was working fine in the evening. Before going to bed I placed it in my bag, and in the morning when I resumed from sleep neither touchpad or keyboard was working. I think I restarted the computer due to an update earlier in the day before it stopped working.
What I've tried:
- SMC reset
- NVRAM reset
- Clean reinstall
- Reseat the keyboard connector on the logic board.
None of them changed anything. Any suggestions would be very welcome!
