Annoying background sound in the new laptop

[RMT42]

I bought a brand new laptop and started using it today. When it is running, there is a constantly disturbing sound in the background. The sound isn’t loud, but some kind of light hustle or bustle, but I don’t like it. Is there a problem with my machine? I don’t think there should be any extra sounds on the new computer.

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, to provide an accurate resolution, I need a few more details:

• Did you make any changes to the settings of your PC prior to the issue?
• When was the last time it worked fine?
• What are the troubleshooting steps you have tried so far?

While you respond to that, let's try these steps: 

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (Refer to the removable and sealed battery)
BIOS default:(do not skip any troubleshooting steps even if you feel steps are repeating)

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and    Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer. 

And, also run BIOS Update: Follow steps from the link: https://support.hp.com/in-en/document/c00042629
