Answer to: Blank screen,fan spins power indicator lits,battery indicator chargingAs I wrote above I had the same problem. It was stuck somehow before booting (the only thing that showed signs of life was the power on led and the fan). No image on either HDMI, laptop display or VGA port. It wasn't going into BIOS either. Not even the caps lock/num lock led would change state when pressing the keys. The solution for me was to tear it all down and put it back together. Although this is not the first time this happens to me, so it might be an isolated problem. I also replaced the heat conductive paste under the cpu and gpu heatsinks. I know it's not a real answer but it's very difficult to pinpoint the problem without access to the computer, and this is what solved mine.
