This did not work for me. I left the CMOS battery disconnected for a day.

You need to contact HP to get this resolved.

Τελικά μπορούμε με κάποιο τρόπο να αφαιρέσουμε κωδικό πρόσβασης BIOS για την HP EliteBook 6930p????

Αν όχι μήπως θα λειτουργούσε ένας δίσκος λειτουργικού γραμμένος από ένα άλλο HP EliteBook 6930p ώστε να μην χρειαστούμε πρόσβασης BIOS?????
