If you go into the computer, there is a very small jumper with three pins i maybe blue and it is on the motherboard (upper left part on the motherboard)
it should be set on the more right two pins, move it to the left pins, then turn you computer on.
a screen will pop up and it says clear all passwords press enter to clear the bios password
then shut off computer
move the jumper back to where it was
turn your computer on and it should work now
