I just purchased a Nitro N50-640 and I have a few problems with PSU(power supply unit).

  1. When I plug in the computer(Nitro N50-640) the PSU makes a buzzing sound. Note, the computer is not powered on just plugged in and it makes the buzzing sound.
  2. When I do power on the computer the PSU fan doesn't appear to be running. Does the PSU fan only run when the PSU is hot?

Please note that unit(Nitro N50-640) runs and doesn't crash but the PSU issues concern me..

    Update on my PSU issues.

    I tried running Cinebench(multi-core) and Heaven benchmark at the same to draw maximum current from the PSU and the fan kicked on after 6 or 7 minutes.. Note: The PSU was barely warm to the touch when the PSU fan kicked on so it wasn't overheating when the fans kicked on. The PSU must have a temperature sensor that turns the fan on when needed.
