Why doesn't the keyboard dim in bright light?

Well, i bought a Brand-New MacBook Pro (mid 2010), and i'm having some technical difficulties with the keyboard backlighting.

If I am not mistaken, When the Ambient light sensor "sees" that there is enough light to see the keys on the keyboard, it should turn off keyboard backlighting and if there is not enough light, then naturally, the keyboard would brighten.

My problem is that the keyboard dims when there is not enough light to see the keys, but brightens when there is obviously enough light.

Whats wrong? Did I screw it up? How do I fix It?

Sounds to me like the wires are reversed. Take it back to Apple for warranty repair.

I just bought a new 17" MBP, and I'm having the exact same problem. The old ones had a sensor under the speaker grill and the keyboard would brighten when you put your hands over it. The new ones have a sensor at the top by the iSight camera, and it behaves in the opposite manner. :( I'm calling Apple to find out WTF is up.

Just got off the phone with Apple. The guy on the phone didn't even know they moved the sensor and argued with me before talking to a superior to confirm what I told him. He said they've had no other complaints about my keyboard lighting situation, but they are going to keep my case number active. He suggested waiting a while to see if this is a common issue. I'm heading to the Apple store now to see if their display models act this way.

Just got back from the Apple store. Their machines work as expected (keyboard light is off without any ability to adjust the light until you cover the sensor with your finger to simulate a dark environment).

So, I took my MBP over to a VERY bright light and BOOM, the keyboard light went off. So, I'm hoping that it's just my sensor that is very under-sensetive to the light. I'm going to find out though, because I'm taking mine into their store tomorrow.

Hope this helps.
