Thank you for posting on the HP Support Community.
 

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

• Did this happen after a recent window or software update?
• Did you make any changes to the settings of your PC prior to the issue?

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. 

Hope this helps! Keep me posted for further assistance.

It didn't help 😞
If it just did not work toggling the airplane mode.. But the button does not work at all (for example, you can not open the developer console in the browser by pressing F12).
There was no problem until I needed to reinstall Windows(to new version). I tried to install various drivers, reinstall Windows again. Nothing helps.

Bios was updated to the latest version by me a long time ago:

By the way, could the driver stop working after updating the BIOS? I had the 43rd version. Now i want to make downgrade but dont know how.  Update utility doesn't allow make downgrade:

Instruction Update the BIOS manually from a USB Flash drive (outside of Windows) dont work for me:

HP Support Assistant does not detect updates.

I do not know what to do.  Tomorrow I'll go to church to light a candle 🥴 In the meantime...
