I have a laptop with hybrid graphic card. As it is a bit old (2010) the support for it totally stopped, and i can't install the official AMD graphic card drivers as it complains that for notebook they want special ones, and i should use the ones provided by Acer (dated 2011..)

I recently updated the drivers to 13.12 (i have a HD5470m with a gen1 intel) using ones. They work for almost everything, but when the pc (windows 7) wakes up form sleep (or after i closed the screen) the backlight doesn't turn on. This doesn't happen with the intel card.

Is there a way (a system call, a driver call, a openGL/CL/DX method, a cmd command, a software, a ritual dance, whatever!) which can force the backlight of the laptop screen on?
