Well, this is a Novatech Maghallaes, a laptop that goverment gave me. And my problem is that when I turn on my laptop, I choose the OS I want to use, and if I want to use Linux screen works perfectly, but when choosing Windows 7, the screen turns off, it doesn't goes just black, it freaking turns off. Also, my screen works when on Safe Mode or connected by a HDMI cable (my laptop screen works as fine as the LCD Im connected to).
So, I hope you guys can help me, I've searched all around internet if anybody has the same problem as I do, but none gives the same description as I do.
The problem seems to to drivers of VGA in windows, that's why when boot in windows 7 there is no screen and when boot in safe mode it works.
Try the following.
1. Start in safe mode.
2. Open devise manager and with right click on VGA adapter select uninstall.
3. Reboot the notebook.
if the notebook is connected to internet will download the right drivers.
