Comment 4 for bug 1420129

Sorry for the delay..
I just tested a bit more. Closing the lid actually doesn't turn of the light in the screen/monitor and the fans are still runing.

The next test was with open lid and then waiting 5min until it should suspend (as set via System Settings -> Power).
I was streaming music to make it easier to tell when it would start to suspend.
Result:
After 1min the screen turns black as it should.
After 5min the music stops for 2-5sec and then both the screen turns on and the music starts again
After 6min the screen turns black again.
After 10min the music stops for 2-5sec and then both the screen turns on and the music starts again
Then I stopped the test.

Clicking "Suspend" in the top-left menu works perfectly. Both Suspending and waking up again. On an earlier kernel it didn't want wake up again, but now that part works :)

I will test the 3.19.0 kernel now and see if it makes any difference..
