"Administrator" accounts usually have "Administrator" as the keyword, unless someone modify it.
Post says "Cracking of laptop BIOS password", but you said you've already have BIOS password!!

BTW, Is that your laptop?

You can't reset BIOS admin password just by resetting the CMOS (i.e. by taking out the battery). Actually reseting the CMOS is of no use there.
Only one 'legal' thing, that can reset the password is flashing the existing BIOS.

For BIOS Pass Reset
Click to expand...

AFAIK jumpers are for some configuration changes for motherboard. Details are written on a paper which is stick inside the cabinet. They can be used for resetting the BIOS pass.

^I don't think there's anything wrong in it. Its just a BIOS password (universal pass may be).

I think it's a Master Pass for BIOS and if someone with wrong intention can easily clear the BIOS Pass protection!

LOL @ password and people worrying about it ... even if its a correct BIOS password.. it would work only on that laptop and with physical access to it.. take a :chillpill: .. IMO if someone has set his password then he should just ask for it as he owns the laptop :)

It is one of dell inspiron's master pass. Not many people have any idea about those set of master passwords. They are generally used by service center guys, that's all.
