Hi folks, recently I have troubles with startimg my Aspire Nitro laptop. Two months after battery replacement, my laptop started to show black screen during startup phase and is not able to run windows, it is not even showing Acer green logo. I was able to start windows sometimes, after few turn off/ turn on cycles, but nowadays it seems I am not able to start win anymore.

When I turn on the laptop:

  • Keyboard backlight is on
  • Fans are running, but not at constant speed, they speed up and immediatelly slow down in regular cycle about 15Hz (increase revolutions for 2 seconds and immediatelly decrease them for 2 seconds - like fast breathing)
  • I cannot access BIOS with any key combinations
  • Start with unplugged battery did not helped
  • I tried to perform battery reset by pressing the small button in the middle of the laptop backside
  • I connected external monitor but it did not helped
  • I tried to uninstall NVIDIA drivers

I would appreciate any hint from your side. Thanks a lot.
