In my opinion call Dell and let them unlock it.
I have a dell inspiron 1525 that is locked. I turn on the laptop and the dell logo comes on and the it goes straight to a white screen that says. this computer system is protected by password auth system. Cant assess data without correct password. Must type in system or admin password then enter. i dont know the password. How to bypass or delete this screen to open windows vista and computer? please help asap, thanks wendy
