I recently bought an Acer Nitro 5 AN515-54(like 2 months ago).A few days ago,it started to make an sound from the top left of the keyboard(like coil whine).This happens only at idle and while the charger is plugged in.The sound is not coming from the charging port or fans which are on the right side of the laptop,not left.I opened the back cover and it is coming from the CPU.Is it normal,will it destroy the CPU on long term?

    Coil whine usually happens under heavy load plugged in, not idle. Check task manager CPU usage when sound is present. Jack E/NJ

    This is the task manager at idle.Nothing special,normal temperatures ,normal load,normal bus speed,the sound is here everytime the charger is connected,as soon as I remove the charger or there is some load on the CPU,the sound is gone.Also,if I change the power mode to best performance,the sound is just a little bit louder,if i put it in battery saver,the sound is becoming quieter.

    I will try re-installing Windows and also installing Linux ( PopOS or Ubuntu) on another drive and see if anything changes.

    No. Don't re-install anything if it's working OK other than the sound. It's probably 50-60Hz AC. If it seems like higher frequency, move the laptop and charger to another room on another circuit because it's probably an appliance or device on the same circuti. Jack E/NJ

    Even I'm facing the same problem like yours, I can hear a low buzzing sound (not from the fan ) from my newly purchased Nitro 5 laptop, the sound is not constant though, usually after 5-7 minutes interval. I think it might be the cpu or may be the hardrive. I'm not sure enough other than that my laptop is working just fine.

    Try moving it to another AC circuit in your home. Jack E/NJ

    I already tried that, even in another house, other charger, the sound is still there. 
  • It can be coil whine, but it can also be the faulty power adapter. Do you have how to test the notebook with another power adapter?
