hey I do have the same problem. Everything is working but no display.. I went to their service center and they told me they need to replace the motherboard when I asked whats the prb in motherboard then he told me nVidia GPU is gone. Now the whole world knows that they have put faulty GPU in the laptop but they are not willing to give any repair fe of cost.
They want me to pay them 20000 to replace the motherboard.
