Since a few days I got a new laptop/Notebook an Apple Macbook Pro 13″. And yesterday i thought yeah lets show the cool feature of the laptop the backlight of the keyboard. Unfortunately they key ( F5 + F6 ) didn’t work every time i got an icon in my screen Ø not available.
After some searching on the internet I read that it was the
Ambient Light Sensor. This sensor is catching so many light that the Apple Mac os X Snow Leopard is disabling the keys for using the backlight for your keyboard.
This sensor is on the left side of your webcam in the screen.
