I have the same problem with my L520, too.

I also have an external VGA Monitor connected - I got graphical output there an
can work with it normally. But my laptop screen stays black all the time. Also
after rebooting the machine, sometimes the laptop screens brightness is darker
than it should be at boot time (which I find quite weird).
I use Arch Linux, Package linux-3.2.1-1
