Hello again,
As I mentioned before the laptop still working with external display via HDMI cable also I use it with TeamViewer to try different methods.
So I plugged an external monitor and booted into window 10 pro and the Geforce Experience had a new driver update and I installed it but what I basically wanted is just to use teamviewer to try to delete couple programs or change drivers etc...as the latest driver has been installed and the teamviewer turned on I just unplugged the HDMI cable and the laptop display suddenly switched ON and worked perfectly. I forgot to mention that the laptop was disassembled before this and I just did put back couple screws and nothing else. So the display was good and I was an idiot as I did not even checked in the windows system which driver working at that moment for the monitor. Anyway, I played a little bit and also checked the temperature and the rest of the sensors for a while. I also moved the lid of the laptop...definately not the cable,not the connector and not the display were faulty...after these I went to sleep and when I woke up couple hours later the laptop was Off which is okay as the power managment did that. I tried to turn the laptop On and I got black screen again but still working with Ext Disp...
After this I flashed the latest bios (released in 2013). It went well but the problem is still up and I just really don't know what to do or what was caused this. Tried to change screen function with FN button...also win button+P and these key combinations without any result.
So does anyone have any idea? Please! 🙂
Sry for my bad grammar.

Thank you for giving me advices guys!
I will try these things..I got rid the OC Util and that EVGA stuff and used DDU to get rid the Nvidia drivers and manually look after the specific one...problem still up.

The FN+F7 and FN+F8 combination had no result. Next will be the Full factory reset (I will put it back to zero) just i have to go to work so I will do it tonight.
I'm just thinking about that the lid magnet sensor could cause problem if it does stuck in closed position even it is opened? That might worth a try to check it I guess.
I took it apart anyway just don't know where to find it. Needless to say CMOS reset done already.Cables still looks fine. Or the videocard might be loose just that much to don't let the display work properly? In that case the ext.screen would not work though,right?

That is a good point, it could be causing issues.


As for the mechanical test, I mean putting a bit of physical strength on and around the screen to see if anything happens.

Hi guys again,
So the happening today was that before I went to work I started the Asus Backtracker using ext.display just to see how to start the utility.
It is quite difficult to do anything when you basically blind. 😄 😄 So the point is that this method was unsuccessful too as it is stucked somewhere because when I came home after my 8hour shift the machine was in the same state like I left before.
So my question is that is there any other method which can put back the machine into the original factory state?
Or do I have to get a Win10 boot USB and try to make new partitions and format them manually? ( The original installer disk has been lost)
Also I demagnetized the sensor and does not make the screen working...
So...The show must go on...:D I'm doing further testings. Like totally take it to it's atoms and just reseating the videocard and the cooling pipes but first of all I need to buy proper thermal paste...but I still accept different ideas obviously until this get solved.
At the end of this proccess there is two option...
1, I'll be menthally f@&#d without my gaming laptop...
2, Or an expert of my working gaming laptop.
I vote for the second if it is possible 😄 never give up.
I never gave any of my mobiles or computers or electronic stuffs to any service to repair and I won't breake this now. 😄

A few things I'd like you to try (if you want):

- try a mechanical LCD test and see if anything happens

- try using the FN+F7 key combination

- try using the FN+F5/F6 key combinations

- while on external display, please try doing a quick Windows recovery

Please reply with your findings 🙂

Can I ask that how do you mean "mechanical LCD test". The LCD just worked fine a day ago until the power managment turned the machine off. After I turned on i got black screen again...So it just gave me a little hope about is not a hardware fault.
