You can go to BIOS setting and reset to factory default.
or use this to software if you forgot the BIOS password
This removes bios password from any Dell machine. unrar it and Burn the Boot CD, and then Boot to it.

Hi, the cmos battery is not under the keyboard, take the side off your PC and on the motherboard, (the first thing you should see) there should be a 3 volt battery (about the size of a 20 cent coin), remove to reset cmos. If you need any more help locating the motherboard just ask, Cheers

The most common way that most of us 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 Cmos battery for 30 minutes from the motherboard.
You need to open the PC case, then look for a 20mm (3/4") shiny lithium button cell.
some motherboards cmos batteries are soldered in
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 the battery power, the BIOS/CMOS settings will be erased.
cmos battery Under the keyboard or bottom of laptop -
If you are working on a laptop computer the location of the dipswitch
(almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.
hope this helps
