Solved Installed Backlight But It Doesn T Work Macbook Unibody Model A1278

Chosen Solution

Hey everybody, I installed the backlightpanel into my MB Unibody A1278. I followed the instruction given on ifixit.com. Every cable is exactly connected, but the keyboard is still not illuminated. Has anybody any idea to get my keyboard illuminated? Thanks for any helpful answers. Christian

Hey there, now it works. There’s a sensor installed and this reduces the brightness. I didn’t know that it is build in. Now my backlight shines and looks great. Thanks for your help. An by the way: The F5 and F6 keys have no sign, but work the same way… Christian
