TPM issues

[Cehlinger]

I wanted to reinitialize my HpEnvy x2 11-g080ef
as I had different issues. It is computer running windows 8 upgraded to windows 8.1. So i used my self made usb recovery key to reinstall. The process started properly but after a while i had this message "A configuration change was requested to clear this computer tpm press vol_up to clear the tpm press vol_down to reject this change request and continue.." and now whatever i do pressing the vol_down key ou even vol_up nothing is happening. I cannot even enter into the bios anymore no reactions at all. It is like the pc is dead !
I went through solutions posted in the hp forum like using a USB keyboard ( nothing happened) then restarted the notebook holding the power and the vol_down+up for at least 5s . It started and then came off again and the bios did not load as expected. Now I really stuck and don't know what to do anymore.
Can you please help ? I just have a dead machine.
thank you

Thank you for your answer but unfortunately none of the keys are working tried esc, f1to f12 del .., and when I do what I read on the forum previously, pressing together volup and voldown key with the power for at least 5s to try to enter into the bios, the notebook starts ( light on) and then stops again.
