Coil whine and loud fans when charging + coil whine when not charging and keyboard backlight are on

[Luka_]

I was realy happy with this laptop but it is starting to piss me off. 

I can't understand how a brand new 1400 dollar machine is not fine tuned and not working the right way. 

First it started with the audio delay that I had to fix myself. After that I found out that my keyboard backlight creates this annoying coil whining sound that drives you crazy. To make it even worse the laptop's fans make a really annoying sound when it is charging + the coil whining sound is very loud when charging. 

Help me because I will be getting rid of this laptop if it isn't fixed. It is driving me crazy.

Can't understand why there is a P2P forum but no possibility to contact hp by email about problems.

@Luka_,

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I see you from your post that you are having issues related to your notebook. Don't worry we're here to help you.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any software or hardware changes on the PC before the issue started?

Have you tried to update the drivers either using Windows update or using HP support assistant.

Did you try to update the Bios?

Have you tried to run any test on the computer from F2?

This looks like a possible hardware failure, however, I would suggest you try these steps here: 

Let's start off by performing a Hard reset on the notebook: 

Before power resetting your computer, do the following:

1. Disconnect or remove all peripheral devices. Start up the laptop and test the computer by itself, and then reconnect one peripheral device at a time.

2. Turn over the computer and look for a battery compartment door.

   • If there is a battery compartment, use the steps in Reset a laptop with a removable battery.

   • If there is no battery compartment, use the steps in Reset a laptop with a sealed or non-removable battery.

I would recommend you run an extensive system diagnostic test on the computer from F2(Please remember to capture the failure ID for further assistance).

If the test fails, then it clearly indicates a possible hardware failure. I would recommend you follow the instructions suggested in the private message.

If the test passes, I would suggest this could either be a software or driver conflict.

Next thing, I would suggest here is to Run Windows Updates troubleshooter -

Download and install the troubleshooter from this link.

Now try to perform Windows Updates - 

1) In the search box, type and open Windows Updates. 
2) Check for updates. 
3) If the updates are available, click on install and restart the computer. 

Next thing, I would suggest here is to update the Bios, Chipset and graphics card drivers on your PC either from our HP support website, using this link or you can download it using HP support Assistant.

To download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.

Refer this link to know how to use HP support assistant.

I will share you a private message with details. Please watch your inbox for more information.

Let me know if this helps!

Have a great day ahead! 🙂
