Reseting BIOS password via CMOS removal is not working.

My brother is a jerk, and put bios pre-boot authentication on my Dell laptop (relatively new) with an unknown password. I think ok, no problem. Iv got this. :thumb:

Since reseting via software is not an option, I just fall back on the CMOS coin battery removal to clear the BIOS password, which has worked for me before on a desktop. Took it apart with no problem (thankfully it was above the motherboard, did not have to mess with that) - and took it out. I go to sleep, and a solid 9 hours later I boot it up with the bios boot authentication still there. :banghead:

Either:
A) I am missing an important step once I put the battery back in.
B) There is a back-up-back-up battery somewhere that prevents it being cleared so easily.
C) There is a lot of static electricity that keeps it going. This is what I am counting on until I get a reply from you guys and am leaving out the cmos for a week or so. (Could I ground it somehow?)

Thank you very much in advance!
ps. I took out the battery pack for those 9 hours and the duration of my work.
pps. Calling dell and getting a master pass is also an option, but I do not have a warranty and will not shell out the $60 they want.
