Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.

Does anything appear on the screen of your ProBook, *before* the message about "HP BIOS application" comes up ? this is an important detail.

The HP logo should appear, at least - but, does anything else? before the HP BIOS application message.
