Received a dell inspiron 100 from a friend who lives in New Hampshire, who received it from another friend. When I first received the notebook it was working properly. In my effort to install wireless connection device. I turned off the computer and the next morning when turning it back on it says i need a harddrive password. I can't do anything on it. F2 or F12 does not come up just the window that says I need hard drive password. Can you help.Appreciate any assistence you can give.
