Welcome to HP Community

I have gone through your Post and would like to help

I suggest you perform a System Test to confirm the Hardware Functionality

- Shut down the Notebook completely
- Turn it back on, then tap the Esc key repeatedly until the Startup menu screen is displayed.
- Press F2 to select System Diagnostics.
- Click System Tests, then click Extensive Test.
 

If all the Tests pass please perform a Reset. Link: https://support.hp.com/in-en/document/c04742289

Keep me posted how it goes
