in TroubleShooting

Hi Guys! I’m not sure how you manage to lose the BIOS password for your HP, Compaq, or HP mini notebook but I presume it is one of the following:

  • Did you forget the BIOS system password for your HP, Compaq, or HP mini notebook?
  • Did you just purchase a 2nd hand laptop from amazon or Ebay and realized that the system is password protected?
  • Or did you steal that laptop/notebook? If you did, then leave my site now. This tutorial is not for you.
  • For all other reasons, feel free to continue reading the instructions below.

How Tech Savvy are You?

First, I want to know your level of knowledge with computers because if you are the kind of user who understand computers well then I suggest you go straight to dogber1, the programmer who made all this possible, Here and do the code generating yourself. For those who are not technically inclined, I am here to help you. Rest assured that I will do my best to provide you free and prompt technical support.

Disclaimer:

If you continue to read this article, then you accept to my terms that I did not program the code for generating your BIOS passwords therefore I cannot guarantee the accuracy of the passwords generated through this article (I should say that the passwords I provide has a 99.99% accuracy if done correctly. Thank you dogber1).

Things you Need:

Let’s get into business. Please make sure you have the following at hand.

  • A pen and paper.
  • A working Email.
  • I’m assuming you are on another computer right now, so have the locked notebook ready as well at your reach.

Instructions:

  • Turn off the Locked HP Notebook and Turn it on again until you see the Bios password screen.
  • Once you see the password screen, enter 3 incorrect passwords and take note of the Error codes generated. Please see below.

  • Write down the Error letter/number Code and send it to us. You need to register first so we can send you the instructions. I will get back to you with the generated password shortly after you confirm your registration (Usually within 12hours or if you’re lucky, I may reply to you instantly).

    HELP !!!

  • Bizhan Faripour

    I tried to enter three numbers, and it locked up as predicted, but I got no error code. All I see is a blue box with “power on password”, and no box to enter anything in.

    HP Compaq tc4400, I believe it was the HP protect tools program.

    thanks,
    BF

  • Djangoza

    I have the same problem,… no code! What to do?

  • http://myworld.ebay.com/seacoasttrader LukeScooto

    I have a HP/Compaq 6530b, same as the other guys, and i have the same issue, no code. But is the code just the part number or p/n, or s/n, or serial number? Cause if so they’re printed on the bottom of the laptop itself. Or is this lock on a seperate security chip that would need to be replaced to get around the locked bios? Any thoughts?

Press the power button to restart” All works fine with Windows 7 pro but need BIOS password as the wireless and bluetooth have been disabled in BIOS and I neet to re enable them. Happy to donate if you can help me. thanks

    Hi!
    I need help with my Compaq Mini 110, When I startup it requests me to enter CURRENT Password,
    After entering it 3 times I get this message: Password check failed. Fatal Error… System Halted. CNU93536QN
    Is there any way to bypass or disable it.
    Please help.
    Thankx

    • broAhmed

      Hey Darney. There is now a simple online solution for this. Go to bios-pw . org and enter in the error code to receive the master BIOS password. I went ahead and entered your error code (CNU93536QN) and it gave the following password: e9lofqfg59 Give it a try and let me know if it works!
