I have a locked Dell computer right now where when I get to the PBA screen, the computer is already locked and is telling me to contact my administrator. I do have the username and password but am not able to enter them in. I am using Build 8.10.1.14. I have tried using the recovery steps seen in www.dell.com/.../SLN293247 but was not able to get this to work as for some reason my recovery .dat file did not work.
