Bug#748701: linux-image-3.14-1-686-pae: Laptop screen dim. Brightness controls do not function

[Marcelo Laia <marcelolaia@gmail.com>]

The same (or similar) issue here!

After upgrading from linux-image-3.13.1 to 3.14.1, the screen on my
laptop (a Dell Latitude D630) turn screen to black all time I remove
the AC cord from energy plug and all the time I plug de AC cord to
energy plug. If I leave the laptop until it change the screen to black,
to save energy, the fn+birghtness not function any more: screen turn
black and I need to boot the system. Booting to the kernel image 3.13-1,
using grub, resolves that issue. However, all time I not remember to
change this at the grub and the system go a head using 3.14.1.
