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.

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,
