Dell keeps a master code for each of their machines. All you have to do is transfer ownership of the machine into your name, if it isn't already, and give tech support a call, and they'll give you the code over the phone. You can transfer ownership at Dell's support site, there a subcategory on the left of the screen that reads "ownership transfer". Here's a link for the tech support number.

try to remove the cover of your laptop. Then remove the motherboard battery for about 10 min. Put it again and bios should be restarted.

SOURCE: how can remove the bios
To reset BIOS take the battery out, if that does not work you will have to reset jumper J1. If that didn't help, you can use third party software from Hiren's Boot CD, it has password reset tools under BIOS / CMOS Tools.
