The aim is to reset the BIOS so that data concerning passwords are
cleared out. This is done by moving a jumper on the motherboard.( The
biggest challenge is to find it).
Note that: This procedure also resets the BIOS settings. If
you have made changes, this manipulation will reset these features to
default.
If the jumper is on 3-connector pins, place it on the middle and the initially uncovered pins.
Wait for some time and put the jumper in its original position (PIN1-PIN2).
If the jumper is on a 2-connector pins and that it holds on a single
pin, place it on both, wait one second and then return it to its
original position.
