Ok, I have a dell computer. The previous owner password protected the computer. Not the Windows OS but the actual computer. I can't access anything. I removed the CMOS battery for about five mins and put it back in thinking this would remove the password protection. It didn't. Now the keyboard won't let me enter the password. The keyboard is working, and I've tried two other keyboards, also, but the computer won't let me enter a password. ANy ideas? HELP PLEASE!
