Do you know what each wire from the ALS does? Previous owner broke the connector socket off the logic board; now the computer thinks it’s always in maximum ambient light, so the keyboard backlight is disabled. Wondering if I can hardwire 2 pins together on the logic board to make it think it’s in minimum ambient light, so I can control the keyboard backlight manually. Thanks!!
I found a much easier solution: There is a free app called LabTick that allows you to adjust the keyboard illumination regardless of input from the ALS.
