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 this happen after a recent window or software update?
• Have you made any hardware/software changes?
• Are you getting any error messages?

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

Hard Reset: Follow the 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 to Exit Saving Changes?
6. Follow the prompts to restart your computer.

Hope this helps! Keep me posted for further assistance.

Hello and thanks for responding. This happened before an update. After realising that it happened, i thought perhaps i need to update to Windows 11. I did that, it did not solve anything. Then i downgraded back to Windows 10. The problem is still persisting. 

I cant follow the link you provided on my PC because i have no internet! Remember this laptop does not have an ethernet option of connecting to the internet. Im replying you via a different device. So i will be trying out the BIOS update and will give you feedback on that one.

Hello again. Unfortunately the update didnt help. If it would be of help, wifi adapter is missing from the list of network adapters in Device Manager. Only the 'Microsoft WiFi Direct Virtual Adapter #2' shows up after i have clicked 'scan for hidden devices'.

Thank you for posting back. 
 

Let's try Microsoft system restore:

System Restore returns your computer to the files and settings from the restore point. Your personal files and documents are not affected.

1. Save any open files and close all open programs.
2. In Windows, search for restore, and then open Create a restore point from the results list.

System Properties opens with the System Protection tab selected.

1. On the System Protection tab, click System Restore.

The System Restore window opens.

1. Click Next.
2. Click the Restore Point that you want to use, then click Next.

The confirmation window opens.

1. Click Finish to restore your computer to a previous point.
2. Do not interrupt System Restore when it starts. This can corrupt your hard drive and create more problems. Click Yes in the warning that appears.
3. System Restore returns the computer configuration to a previous point in time and restarts.

Hope this helps! Keep me posted for further assistance.
