I'm lovin my new 13" MacBook Pro (I'll be sharing more interesting topics later) but for right now I have a quick question.

This is my first computer with a backlit keyboard and it rocks! I'm sitting typing this sitting on my deck outside in the dark! lol. Anyways, to prevent draining the battery, I have the "timer" set in the Keyboard section of system preferences to automatically turn off the baclklit keys after 1 min of not being use. That works fine because after a minute of not being used, they turn off. HOWEVER, when I go to use them again, I try and start typing and they don't come back on??? Is this normal? I then have to scramble around hitting every F key trying to find the one that manually turns the key lights back on. And then when I do that, they don't automatically turn off again!

Am I doing something wrong here? I thought that after not being use they would turn off, and then when I started typing again they would come back on? Maybe I'm expecting too much? I don't know.

Any info or suggestions on this would be great!

    When they shut off.. once you touch the touchpad or hit a key, they should come back on. I just did a test and had them shutoff after 10 seconds. As soon as I touched my touchpad or hit a key they came back on. Try different settings and see if it behaves the same way.

    If nothing else works, try these two things in this order:

    The keyboard backlight should come back on as soon as you touch the trackpad or press a key (as long as you're still in a dark environment). Mine certainly does.

    hmmm. I adjusted my time from 1 minute to 10 seconds and it works just as you said. So maybe there is something wrong with 1 minute. I don't know, but it seems to be working now. Thanks.

    Hi everyone,

    I am having keyboard backlit problems with a Macbook pro 13 mid 2009 as well.
    The backlit keyboard behaves very strangely:
    - if the machine is switched on with enough light, it is impossible to have the backlit activated if it is put in darkness
    - if the machine is switched on in darkness, the backlit usually activates, but then it seems to stop after some time. The backlit disappears; when pressing F5/F6 keys it says no action is possible. At some point the sensor regulation reactivates and the backlit reappears. What is really annoying is that the screen light varies as well in the meantime, which is not comfortable in darkness.
    - in low light condition, the system screen backlit/keyboard backlit enters in oscillation: screen backlit decreases and keyboard backlit increases then screen backlit increases and keyboard backlit decreases.

    Does anyone have any info or suggestion on this?
    Thanks in advance,
