Samsung n150 Plus, I can't control bright

Specs: Windows 7

I people, I have a Samsung n150 plus netbook, it cames with Windows 7 from factory and now I've installed a fresh copy of Windows 8, everything run fine, except the bright control doesn't work at all, the bright is actually set to highest level, so my eyes ar burning and my battery is out quickly.

I searched all the web loking for a solution and nobody seems to know. The graphics card built in is a GMA 3150, I've tried with several drivers with exactly results.

The only thing I can do is to disable the GMA in Device Manager and reboot, then in bios set the bright to minimun and then load Windows 8, only then my bright is set up to minimun as I like (I work at night with no lights)

Hope you guys can give me a tip or a solution, the graphic card driver seems can't control backlight panel, but everything goes fine with Windows 7, I dont wanna go back to W7 after try W8.

Please help me, thanks in advance.

The problem is probably due to the fact that Windows 8 is not officially supported for the N150 range.
Samsung have not released any Windows 8 drivers for that model. Since the brightness control works fine on Windows 7 (which is officially supported), that has to be the reason.

You have to remember that notebooks and netbooks require custom drivers from the notebook or netbook manufacturer to match the custom-made hardware. Samsung has no Windows 8 custom graphics driver or chipset driver for your netbook.

You seem to have been lucky with the rest of the hardware if everything else works, but I can't see how you are going to fix the fix the brightness problem if you insist on using an unsupported Windows version.

You should have checked to see what Samsung drivers were available before upgrading to Windows 8.
