you boot up to the log in screen type in administrator as user to log
in if you cant log in
the boot up process you will see on the screen for a short amount of time press
a certain key to enter set up press and
hold that key during the boot up process to enter BIOS scroll down to set user
password or supervisor password you can change or remove your password from
most common way that we know on how to reset or clear the BIOS password is to
physically remove the power from the computer by disconnecting the power plug
and then removing the Cmos battery for 30 minutes from the motherboard. Another
way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2
methods mentioned works because most motherboards use a battery to sustain the
BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the
battery power, the BIOS/CMOS settings will be erased. Hope this helps you
