working on a 820-3437 macbook air with no backlight(why does it seem i suck at this.) so what I've found is that i have no backlight enable coming from q7707.
pin 1 has 0.0v
pin 2 has 3.33v
pin 4 has 0.0v
pin 5 has 3.33v
pin 6 has 0.0v
i chased the backlight reset to plt_reset_L coming from the pch. kinda lost on possibilities.
