Administrator password startup

Hello,

I have an HP laptop and at startup, it shows me "Administrator password or power on password."

I tried the master codes found online with bios pw, but no results. I did a CMOS reset by disconnecting the battery and rebooting the BIOS, still no results. Lastly, I tried recovering the BIOS through HP support with a USB key, but again no results. I'm lost, what should I do? My motherboard has no battery or CMOS reset.

Configuration: Android / Chrome 91.0.4472.120

    Hi,

    If it's not a battery, is it a supercapacitor?

      Surely yes, I don't know, no reset button, no battery.
