[SOLVED] 820-3437 No keyboard/trackpad

[wirelessplanet]

Had a board that did not turn on. I had 5v on pp5v but no volts on pp5v en. So I applied same trick on this rossman video: https://www.youtube.com/watch?v=IVgKJF_dIy0
I reset pram, and now the board turns on with no issue. while turning on it asks for filevault password the keyboard and trackpad work. when its all booted, it can't find keyboard and trackpad. any ideas?

Trackpad/cable/connector are the first suspects.

I'll replace it duke but why would it work in during bootup and not afterwards.

 

[dukefawks]

In boot menu the trackpad works as USB device, in OSX it is a SPI device. Usually it is the cable.
