I have a Gateway model 600YG2 laptop. Recently I attempted to remove the power-on password. I entered no password (pressing enter) on the bios password update screens (assumming this would remove the password). This did not work as I can no longer boot my laptop, and the old power-on password does not work and neither does entering no password (pressing enter). Is there a power-on password which still work (when I attempted to clear the power-on password)? How can I update the bios to remove (or change) the power-on password?
