    Hi @Serg008,

    Can you please post "HP Compaq nc4400 Notebook PC (version F.0C 09-jul-2008) whitelist removed" once again?

    I've tried all the links in this thread and none is working... :-\

    Thanks in advance.

    @Serg008

    Hi, how can I rollback the BIOS on the HP Probook 4540s?

    I tried via HP UEFI Diagnostic Tools (has bulit in option for rollback) but says invalid signature file. I tried download the files again but the same error. I tried via Windows key + B key but the caps lock is blinking and the CPU fan is at maxim speed and that's it. I never get the bios update screen. I can only install the current version of the BIOS.

    My problem is here:

    https://forums.mydigitallife.net/threads/strange-problem-with-probook-4540s.78557/

    And the rollback of the BIOS is my last solution right now

    I appreciate any help! Thank you!
