I have gone through your Post and I understand your concerns

Let's try  BIOS Recovery and check if that helps

1. Turn off the computer.

2. With the computer off, press and hold the Windows key and the B key at the same time.

3. Still pressing those keys, press and hold the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows and B keys until the BIOS update screen displays or you hear a beeping sound (usually 8 beeps).

   Note:If the key presses do not work, press and release the Power button, and then immediately, press the Windows and B keys at the same time, repeatedly, until the computer beeps or opens the BIOS update screen.

   The power LED light remains on, and the screen remains blank for about 40 seconds before anything displays on the monitor. You might also hear beeping sounds. Eventually, an HP BIOS Update screen displays and the BIOS update begins automatically.

   

   • If the HP BIOS Update screen displays proceed to the next step.

   • If the HP BIOS Update screen does not display, do one of the following depending on the condition:

   • Computer starts into Windows: The computer starts into Windows if the power button and keys are released too soon. Repeat the previous steps, holding the power button down for 2 or 3 seconds.

   • Power LED light turns off: The computer turns off if the power button is pressed and held down too long. Repeat the previous steps, holding the power button down for between 2 and 3 seconds.

   • After repeated attempts, the HP BIOS Update screen does not open: Your computer does not support this function or it has a hardware problem that is preventing the tool from opening.

4. After the BIOS is recovered, a Continue Startup button displays and a timer counts down. Click the Continue Startup button to restart the computer immediately, or wait for the computer to restart automatically when the timer reaches zero.

   

5. When the computer restarts, a black screen displays with a message similar to the following:

   A system BIOS Recovery has occurred.
   BIOS Recovery (500)
   Enter - Continue Startup

   Press the Enter key to continue immediately or allow the computer to restart automatically.

   Note:After restoring the BIOS, if the computer repeatedly displays a message about the BIOS, update the BIOS. 

6. After restarting, Windows might display a message stating that the computer was improperly shut down or that a boot problem was detected. Read and respond to the screens to continue.
