Hi, I'd like to reopen this thread. I have the same model, but when I log in with F10, the first thing it asks for is the administrator password, and there's no reset option. Three attempts and it freezes.
HP ZBook Firefly 14-inch G9 Mobile Workstation PC
SKU Number 74Z93UP#ABA
System Board CT Number PRJKE00WBHZ0K7
Is there any other way to reset it? Thanks for the reply.
