Resetting BIOS Password 91
Resetting BIOS Password
BIOS passwords are used to add extra security to computers. You can
configure your computer to prompt for a password when booting or when
entering BIOS setup program.
Use one of the following methods, depending on your computer type, to
reset lost or forgotten BIOS passwords.
CAUTION: Resetting the BIOS password involves clearing all data
fromthe CMOS. If you have changed any BIOS settings, you must
make those changes again after resetting the password.
Remove the CMOS Battery
WARNING: Read the safety instructions before working inside
yourcomputer.
Almost all motherboards use a coin-cell battery that helps retain BIOS
settings, including the password. To reset the password, remove the
coin-cell battery, wait 15-30 minutes, and then replace the coin-cell battery.
NOTE: For more information on the location of the coin-cell battery and
instruction on removing and replacing it, see the ServiceManual at
dell.com/support.
Use System‑Board Jumper
Almost all system boards on desktop computers contain a jumper to clear
CMOS settings along with the BIOS password. The location of this jumper
varies depending upon the system board. Look for the jumpers near the
CMOS battery, usually labeled as CLR, CLEAR, CLEAR CMOS and so on.
There are 3 pins. The jumper joins the centre pin to either the left or
right pin. Remove the jumper and join the centre pin to the opposite pin.
Waitfora few seconds then remove the jumper and join the centre pin to
originalpin.
WARNING: Read the safety instructions before working inside your
computer.
NOTE: For more information on location of the jumper and working
inside your computer, see the Service Manual at dell.com/support.
