Removing a BIOS password?

My friend has an Alienware M11x that she got from her friend, it was left in the lost and found at a college one of their relative's worked at and it was there long enough to be forfeit, long story short it worked fine, until about a week ago she brought it to me and I fixed it, but one thing that is a hinderance to me is that it has a BIOS password on it that she doesn't know. I will be the one working on it and she won't be going into it at all, I needed to get into the BIOS previously when it wasn't working the first time, but was unable to. Is there a way to remove it without physically taking it apart and removing the CMOS battery? The reasons that I do not do that is primarily because I know it works fine right now and I do not want to run the risk of messing it up by tearing it almost clear down to reach the CMOS, and they are just a pain to try to work on from the inside. Could anyone help me remove it?

Thanks,
