Today i was searching around and i realized that macbook pro uses discrete graphics when you connect it to external monitor (amount of graphical load doesnt matter) and when you disconnect the external monitor it will be switchable due to load
I was thinking in my case may be an issue with igpu , so i diged deeper and found a terminal command that will set gpu on discrete mode permanently
Guss what !!!!
The image didnt go blank and now the machine works very good on its internal lcd (with or without connecting to external monitor)
In this way...

Thank you so much
The interesting thing is when the external monitor is connected you can use all the options in display settings (main,extend,mirror) without any problems
btw i will do some inspection around u9850 and will inform you if i find something...Leave a comment:

Yes, lid sensors are ok
i booted the machine into safe mode and lcd worked perfect , closing the lid will put the machine into sleep and it will be ready as soon as you open the lid
in normal boot another thing i realized is: only the image will go blank , the backlight is activated an on
i dont know why the lcd works perfecf in safe mode...Leave a comment:
