I reset my laptop and selected to delete all my files and re-install windows since i was selling the laptop. But after it reached 100 % screen turned black after that i tried number of things but there is black screen and keeps are lit and there is beep sound but no display. I connected it through hdmi with tv but no display on tv, removed battery and held the power button for 15s but didn't work. Tried the recover bios step with windows+B and power key but did not work either.
