Customer brought a compaq nc6000 to me and says that she cannot get into her computer even though she inputs the right password. Thinking that the hard drive is bad, I replaced because when I took out the old one and tried to access it by plugging it to my computer I could not access it. After installing the new one, it still ask for the password at startup. I cannot get into the bios, nor can I boot from the dvd because of the password. So I reset the bios by uplugging the system battery, but that did no good either. So I am really needing some help. Thanks in advance.
