Just purchased an HP probook laptop with 256GB SSD
Was using power on password.
Suddenly I see a message BIOS upgrade in process do not turn off computer.
After it finished, my password no longer works.
It is a 4 digit pin I used for many years other things so I cannot forget it.

I cannot power up the laptop and HP said that it is not under warranty.
How to fix this
