I was installing scptoolkit driver for ps3 controller and it asked for a restart. After the restart i noticed Black screen with no predator logo or startup sound but only light bar lit up.

I did a forced shut down by holding power button and then turned it on back but still same status as black screen with only light bar led on and fans start for 2 seconds and stops. I did some research and tried few solutions below with no luck.

1. Tried external monitor and tv.

2. Tried holding power button long press.

3. Tried plugging in charger and turning it on but still same status.

4. Removed back cover and disconnected main battery. Long pressed power button for a 1 min to completely discharge. Connected battery again and pressed power button, again the same black screen, light bar led on and fan stopped spinning as soon as they start to spin.

I have not tried removing cmos battery jack and shorting the terminals on the main board. I have to reopen the bacm cover again to do that.

Any help/suggestions would be appreciated. The warranty has expired already.

    Yes, short the RTC/BIOS battery +&- pins to reset CMOS at the mobo RTC/BIOS battery plug and also take all the ram out and leave the laptop to reset for about 30 min and then reconnect everything and try to reboot the laptop again, if you have 2x ram modules only use one, and see if its not from a faulty ram that the laptop hasn't got an image, then alternate between the two ram modules, as after doing all this, the laptop should reset and give an image post boot.

    If not, then whatever the "installing scptoolkit driver" did could be an issue or the laptops eDP cable is shorted, or when you did the first reset, you have done something internally to the laptop like shorted, corrupted the EC or Chipset or bios or you have shorted a chip that is related to the dedicated gpu, but I hope that you haven't shorted the vram or the gpu, as in these gaming laptops, this is a common thing that happens, as then you will only be able to operate this laptop with the cpu graphics or you will need to replace the mainboard. Good luck.
