I am in a big trouble recently i have received Dell D600 from my friend as a gift after receiving it when i try to turn ON my laptop i receive a message as 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 press enter. I asked my friend about the password he told me that he hasn't given any password. Please help me in this case to remove my password.
