After Bios update, the Bios administrator password is not accepted anymore

[Fred-san]

I installed a Bios administrator password and a Bios power-on password, both passwords are the same. I could login to the computer with the password, everything was working correctly. I updated the Bios to the latest version, no error msg's during update, but immediatly after the update the Bios password does not work anymore, I cannot get into the computer. After 3 tries the system gives the System SN: but no error code. It asks for a HP SpareKey USB Recovery Key, but the key I created during the setup of the password does not work. How can I remove the bios password

I have taken out the battery and waited for more than 1 hour. Re-installed the battery and started the laptop, as expected the laptop says CMOS invalid, CMOS data will be reset. After reboot of the laptop, problem not solved. Immediatly after starting it aks for administrator bios password. Booting with F2, F9, or F10 tried it all, does not work. Also starting with the windows key + B pressed to recover the bios does not solve the issue. Starting with the windows key + C to restet CMOS data does not solve the issue. I am lost...
