An elderly neighbor has a Laptop, he bought it new 3/4 years ago. He never put in a "Password" as a user, no one else has had access to it. Now after he turns it on it requests a 'password'. After awhile, he took it somewhere for repair and they removed the hard drive, so they say, and with the HD removed it still requested a "Password". I find this unbelieveable, am I wrong ?

Sorry I don't have more details. TIA ChiefE7
