    • Release the larger ribbon cable by flipping the brown retainer up so it is parallel with the ribbon cable

    • Gently un-clip the battery from the plastic housing to completely remove it from the laptop

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?????
