Hi guys, The ambient light sensor on my Macbook Pro (late 2008) does not work in Mac OS X 10.7 Lion DP. Neither it dims screen light, nor it lights the keyboard, no matter how dark the ambient is. I can change both manually (and independently) using the keyboard though. I tried resetting the SMC, but it did not work either. I wonder if anyone else has this problem and how to fix it. Thanks.
