If you have had the laptop repaired by HP and it came back with what is in the screen shot above, then you need to contact HP and get them to fix it for nothing.
If not the the options are new system board or a BIOS chip replacement.

I have an HP 4420s Probook and am in the same kind of situation as the person who posed this question. On my 4420s I bought the laptop from a friend with a broken LCD. I bought it for $50 and replacing the screen cost $55 (I put it in myself). The person I bought it from passed away a week after I bought the laptop and I didn't fix the screen until a month later so I never GOT THE MASTER BIOS PASSWORDD and now realize this business pro book has UBER security!! So will I need to replace the bios chip because obviously I can't ask a dead person for the password....This sucks, such a nice laptop to..To get at the board you have to tear it pretty much completely apart. I have the manual and almost the last thing to take out to replace the bottom piece LMAO is the motherboard and I don't think I have the soldering skill to replace a 1mm x 1mm x 1mm bios chip....Is there anyway to get a master password? What do you suggest Professor??

Yes, I just sent AQSTECH an email and asked for this model (just for curiosity sake) they said that usually all the DMI info is available for backup within the original code stored in the chip. He also said that the probook / elitebook models don't store this info in the chip and the DMI utility is needed for those models. Which they have.
