I installed windows 10 in this laptop, with the generic driver everything was ok, but once windows update install the drivers, I have a problem, its like the laptop monitor is not detected. If I plug an external monitor, everything works. If I just select shutdown (using the external monitor) and then turn on the laptop, It works, but if I use restart, then the laptop monitor wont work after windows boot up. I tried the driver from dell, from intel, without luck. Any idea? The problem seems to fix If I just turn off, (maybe because the fastboot feature that was implemented in windows 8.) but if i restart then the problem show again.
