Y510p bios password attempts

Hi,
I have a problem with my bios password. I am not sure about it. I am pretty sure that if I had more attempts i would gues it, because I use only few passwords. I have read, that in some BIOS versions it is possible to try the password again after three wrong gueses, if you restart the laptop. I do´t want to get my notebook blocked, so the question is if it is possible in this version (74CN44WW). 
I need to dualboot ot at least virtualboot Linux, but without the password is is not possible.
Solved!

adolf15,
I've not seen a Lenovo implementation of BIOS password that would permanently disable the system after X number of failed attempts.  On older ThinkPads that I have used, you got 3 tries and if you got it wrong 3 times it was locked until you powered off and then you could restart and try again 3 times, etc.
This was for the power on password.
If you can never remember it, then a board replacement would be required.  But, as far as I know, trying multiple times would not cause you to need to replace the board.

  • Lost BIOS password Hp Folio 13-2000

    Hi,
    I'm hoping for a code like I've seen other users with the same issue get. We've forgotten the BIOS password set on a HP Folio 13-2000 laptop and repeated attempts now give the message System Disabled 68875769.

  • BIOS PASSWORD REST ON 15-J023CL

    Might be JO23cl?
    The character limit forced me to use an unusual(ly short and insecure) password for my BIOS, and not I can't remember it. How can I go about resetting the BIOS password on this system?
    Based on some other threads, it appears the code I get after 3 failed attempts is relevent?

    Thanks! At first, I was confused, as it went straight to the operating system. Then I realize what we had actually done.
    TBH, I'm a little conflicted. On the one hand, I am relieved that I can get back into my bios. On the other hand, I wonder weather the ease with which one circumvent the password through such a back door, simply by coming to one of these forms, might defeat the purpose of such a security measure in the first place. But I digress; thank you very much for your assistance

  • EliteBook 2530p BIOS Password Failures

    My company has purchased 30 or so HP EliteBook 2530p notebooks. We set the BIOS password on every machine. Now, out of 30 or so machines we are unable to get into the BIOS on at least 6 machines. We know the passwords and they have not yet left our lab for deployment to the users. I've been searching for a known BIOS bug but haven't found anything online that I'd call solid. When I contacted HP they had me try all the standard BIOS reset procedures and none of them resulted in the password being reset or able to be accessed. I was instructed to send the machines off to HP so they can replace the mobos. Since they were so willing to do that I assume it's a known issue.
    Has anyone else encountered this? Before I gather up these notebooks and either take them to a local HP contractor or send them to HP is there anything other than popping out the batteries and letting the BIOS reset to attempt to reset the password?
    Thanks!

    Have a look at this article. Helped me. http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01798858&dimid=1137549722&di...
