Uppercase Was Replaced But Keyboard And Trackpad Is Dead Macbook Air

Chosen Solution

Uppercase was replaced with also keyboard replacement but keyboard and trackpad is still dead. External USB works fine. Getting Bluetooth not detected error. but transferring Bluetooth files works fine. Is it the io cable or is it another cable that needs to be replaced. Or is it the io board that is dead, ie motherboard is it dead

You look like you are mixing parts from different series! You can’t mix 2010 and 2011 system parts! You need this cable for the mid 2011 case MacBook Air 11" (Mid 2011-Mid 2012) Trackpad Cable Is your original system a 2010 or a 2011 system as like the cable you need to use the correct uppercase for your logic board.
