BIOS password

By computab ·
How do you erase the BIOS password on a Dell laptop. Is there a jumper to be changed or do you remove the BIOS battery, then wait for the password to die, and how long do you wait?

BIOS password

by Soekratis In reply to BIOS password

Different model will have different jumper location on the motherboard. Try looking under the CPU cover for the diagram. Normally you will need to enable the jumper, boot the system to the bios level, then power-off the system, disable the jumper (where it was) and start the system again. If you don't know where to locate the jumper, remove the battery and leave it for a couple of hour and try starting the system withour putting in the battery yet. If the timing is right... you should be able to get to the bios setup. Shut down the system, replace the battery and power-up.

Good luck

I completly agree to the previos answer, just open the computer, the look for the BIOS, or CMOS jumper, some of them have 3 pins, see the instructions attached to it to clear the cmos. If you can not find it then remove the internal battery (the oneon the mainboard), then remove the external battery, wait for a couple minutes, give it 5 minutes, put the batteries back on, turn it on, and configure the cmos.
It should clean all the passwords.

Good luck,
