Greetings all I am a student technician at my college, and a customer has brought in a Dell Inspiron 1545 to be repaired. He has the white screen saying "This computer system ####### is protected by a password authentication password.... etc etc...My Google search led me here! It seems a few of you were able to offer some assistance in this area to other folks. The service tag on the machine in question is 4D7V2K1, with an express service code of 9506396593 Any help in this matter would be most appreciated. Thanks in advance Mike
