Cannot enter admin bios password

[Ach2]

hi there. 

I just bought an elitebook x360 (Z2w63ea#)  couple weeks ago. I gave it to my college. I have setup a bios admin password and post on password. Now he forgets the post on password. No problems if i have the admin supervisor key right? That is the problem when i startup the laptpp it says: press f7 to change power on password or press esc to enter admin password. I try esc button but nothing happends. It still stays on the same screen? How can i resolve this?

Thanks guys!

I wish we could help you, but sorry, due to changes in Community policy, we are no longer able to provide any assistance with password reset or recovery issues.

Also please note that now, to resolve a forgotten BIOS or power-on password issue, since that password is embedded into the firmware of the system board, to replace that, a system board replacement is required -- and additional customer costs apply, and while the costs vary by laptop model, they are generally around $200 USD. HP has issued this post about BIOS passwords: https://support.hp.com/us-en/document/c06368824.

In addition, according to the Community's Rules of Participation:

For assistance NOW, you have to contact your regional HP Customer Support location directly as they will confirm ownership of the PC before providing any assistance -- something we are not able to do from here.

Hi sir. Thanks for the reply.

I understand it 100% if you forget the password. The problem is that it doesnt popup the admin inlog screen after tapping esc. Nothing happends? Is this a bug or what? I have the Admin password. 100% sure.

Thanks again
