Most computer systems, particularly desktop computers, have an on-board password jumper, which can be used to clear BIOS passwords. Also known as a dip switch, this component can be identified through various labels including CLR, CLEAR, CLEAR CMOS, PASSWORD, PSWD or PWD. To reset the BIOS password on a Dell system using the built-in password enable jumper, follow the steps listed below.
Switch off the computer and disconnect the power cable from the electrical outlet. Remove the system unit's enclosure to access the motherboard.
Find the two-pin password connector, which is marked "PSWD," on the computer motherboard. Take out the connector and the computer chassis.
Connect hardware devices such as a mouse and keyboard to the computer and plug in the system unit along with the monitor to power outlets. Switch on the computer and allow it to boot.
Switch off the computer once the operating system loads. Disconnect the hardware devices and unplug the system unit and monitor from their electrical sockets. Ground the motherboard by pressing the power button.
Remove the computer case. Return the jumper connector back to its original position on the motherboard.
Replace the cover. Turn on the computer and check to ensure that the issue is resolved.
