Some Staple stores have a service to unlock laptops and it's about 50 bucks. Dell may do it as well, but you have to pay for support.
This is mostly a lesson about this lesson (used locked laptops.)
If it's not worth unlocking, I think that's the answer.
We purchased this laptop of a friend (not a very good friend I suppose). We do not know any of the original owner?s information. This is the message that appears when we power on the computer:
"This computer system is protected by a password authentication system. You cannot access the data on this computer without the correct password. Please type in the primary or administrator password and hit enter."
The person sold this laptop did gave us the password.
When typing the password in it said, ?Invalid password?. I?ve tried many times but it still gets the same error.
I talk to the person that sold us the laptop I ask him if he could remove the password but he refuse to do it. I ask if he can give me the owner information but he said he doesn?t have it, because he bought it from someone else as well.
I have opened it up and disconnected the CMOS battery. Left it disconnected overnight. Put everything back together, power on and still get the same message. I have also tried switching out the hard drive and get the same thing. So I don?t think it is a hard drive password. Also I can?t find any software in the software store that could crack/remove the password. From what I could see, there were no clear cmos jumpers.
(I learn these instructions of the net, not sure if I?m doing it right)
It?s a Dell Latitude CPt C400GT, Celeron processor, not sure which Windows it is, it said on the seal designed for Microsoft Windows NT, Windows 98
I Really appreciate anyone who can help me out of this. Thank you!
