Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, I appreciate your efforts to try and resolve the issue. 
 

Let's try restoring the BIOS to default on your PC and check if it helps.

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.

To perform a power reset on a laptop with a removable battery, use the following steps:

1. Turn off the computer.
2. Remove the computer from any port replicator or docking station.
3. Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
4. Unplug the AC adapter from the computer.
5. Remove the battery from the battery compartment.
6. With the battery and power cord unplugged, press and hold the Power button for about 15 seconds to drain any residual electrical charge from the capacitors.
7. Insert the battery and plug the AC adapter back into the laptop, but do not connect any of the peripheral devices.
8. Press the Power button to turn on the computer.
9. If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key.
   After Windows opens, reconnect each peripheral device that was disconnected, one device at a time, until all devices are reconnected.

Hope this helps! Keep me posted for further assistance.

Thank you for posting back. 

The last thing I can suggest try and restore the OS back to the factory default, which will isolate whether it’s a software or hardware issue.  The HP Cloud Recovery Tool allows you to download recovery software to a USB drive. You can use the downloaded recovery image file in order to install the Windows operating system.
