On boot, system says: Enter Administrator Password or Power On Password

[anotherAaron]

For no apparent reason system started booting to what seems to be a BIOS/Firmware password prompt:

Enter Administrator Password or Power On Password

I've searched this forum and it seems there is a way to generate the code for it, but so far all the existing answers do not work for me.  My system is a Pavillion x360 m3 Convertible PC, model: m3-u001dx.  Can anyone locate the password code for me?

After 3 failed attempts it returns:
System Disabled

That is a Disable Code but we're not permitted to provide Disable Code bypasses anymore.

Passwords can NOT be recovered; instead, they have to be reset.

If your PC reset your password on you, we can not help in that because we have no access to either the original or the new password.

We are not permitted to assist in resetting passwords due to HP Policy.
--------------------
For Admin password resets, you have to contact your regional HP Customer Support location directly for assistance.

--------------------
For BIOS or power-on password resets, because the password is encoded onto a chip on the motherboard, replacement of that motherboard is required. HP does not reset the BIOS password on the current motherboard.

If you are not prepared to spend the money to get HP to replace the motherboard, you would have to take the PC to a local repair facility to see if they can do it for you -- but we can not assist in that in any way.
