Gee thanks a million rulisky! That was ruli helpful and well thought out answer....... in case you cant tell, im being sarcastic.... but thanks for putting me on the tea-leaf.... But you did remind me why i used to bash the shit out of geeks that look down there nose at people and think their superior cause they can do long division in their head..... geeks just like you!! i see you spend a lot of time writing smartarse comments on here, to people who just want to learn something or solve a problem... Did you ever stop to think that maybe if you werent such a judgmental egotistical smartarse you may not have spent your entire life in front of your computer pulling your tiny dick?? you may, if you tried REAL hard, actually have seen one of those girls or boys you wank over up close and in the flesh!!! But what do i know about life??? i havent used the word "nefarious" in a sentence ..... well ...ever..????
CHEERS,
You Have a nice Day

Bravo LetmeIn8, that guy acts like a turd to everybody on here.... anyway, i figure you mean a locked bios that is password protected. There, at least for dells, are master passwords that can be deciphered from (i think) the service tag or model number. small hard to find programs are available which do the processing. Alternatively, some internet folks offer the unlocking service for a fee. how to tell if they are reputable though, I am not sure. Lastly, on a toshiba that had a locked startup, there was a point on the motherboard that if grounded with a paperclip, would wipe the memory of the password in the NVRAM(?) -This is for sure dangerous to the hardware, but the owner said "OK" and it happened to work.
BTW, removing the CMOS battery is (useless) for the purpose of removing passwords

Maybe you should try a forum topic. Most unlocking requests are viewed here as nefarious effort to get a code (but not from the owner).

Alternate, take to a Lenova service center for help.
