How can I reset or bypass my BIOS setup password?

Michael Jenkins May 12, 2012

I’ve spent months trying to figure out my BIOS setup password but can’t. I’ve talked to HP Support, they want to charge me money to ship it and get it fixed. I can’t afford that right now. I’ve tried every backdoor or default password there is but NOTHING! Will someone PLEASE PLEASE PLEASE Help me!!! :C

    There is a password on my HP Mini 700 which prevented me from booting, i have tried every means to get access but could not. Does any one have idea of which he can help me remove the password from the CMOS BIOS setup and continue. Thank you.

    Also, remove the CMOS battery and boot up without it in. That may do it.....maybe

    Normally, if you can get the laptop apart enough to read all the writing, you'll see something like "PWD" or "Password".

    If jumpers are already on those pins, then remove it.

    If no jumpers currently there, then place one across the correct pins.

    Boot up and it'll tell you something on the moterboard has changed, "press F* to continue"
    just press whatever function button and your home free!

    What is make/model of laptop?

    I'll try to get some more details for you.

    Can someone show/tell me where the jumpers are located on my laptop? HP Compaq 8510p CNU8273ICL

      I don't know where the jumpers are, but the CMOS is located in step 15 (and on) of these directions:

      From what I can tell, the CMOS battery (coin sized yellow disk, with two wires coming out of it) is readily removable once you get the keyboard bezel off. That shouldn't be too difficult. It probably won't require breaking apart the whole thing, either. When you pull the battery be careful about things like static electricity. Two quick tips: Don't use magnetic tools. Don't touch the circuit board unless grounded (touch metal to discharge).

      However (and this is a big "however"), if this is a "supervisor password" (or some kind of chip-based security layer) this technique won't work. SP means there's a separate chip that controls the BIOS settings and password.

    Hi, I had the same problem on my acer whilst I was experimenting and forgot the password. I tool the BIOS battery out completely and left it a while ... This reset the password and the daft things like date and time. I hope this helps!

    I didn't ask the question, but I think these are better answers than what I had. I was going to suggest buying a chip extractor tool and replacing the CMOS chip.

    I asked the same question and it was never answered. I think it's impossible :/

    A common solution to this problem is reset the BIOS password using a jumper.
    For more info, go to

    However, HP BIOS versions may vary from laptops to laptops. If you can specify the model series and no you are using I might be able to help.

    Hello, most times the easiest way is to remove CMOS battery or resetting the pin.

    HP doesn't wants to give user to tinker with their BIOS.If your BIOS is of UEFI one( i.e. you can use the BIOS with the mouse and has good graphical interface),laptop manufacturers makes bypass of BIOS password hard to go in such systems.

    You can try some methods to solve your issue -

    The site -

    has suggested !BIOS tool.Visit the link above and follow the instructions mentioned under the heading - How to Bypass or Remove a BIOS Password using Software:

    Click on the link below and try the method mentioned under section “By Using MS DOS Command” -

    BIOS/CMOS Password Recovery Tool ($24.95) -

    CmosPwd tool -

    Use Hiren’s Boot CD -

    You need to burn it in CD or you can create a bootable USB of this tool.

    The video shows how to use it -

      !BIOS can't be used because HP isn't under the manufacturers.
      I don't have a disc drive, don't know about Michael, so I can't use Hirens. Can not boot from USB as I need BIOS access to use that.

      UEFI is not a type of BIOS, it is a complete replacement. Just so you know.

      So much effort to crack the password. Just resetting the board would work fine; jumper or removing CMOS battery.

        Thanks for correcting this.I actually committed a grammatical mistake in forming the second sentence.

        I suggested so many methods as if one method doesn't works he can use other one.Some also,do not like to open their laptop internals so I suggested so many software solutions.

    In most cases, unplugging EVERYTHING, removing the battery on the motherboard and replacing it after 5 minutes will reset the BIOS. Many boards provide a short-circuit jumper to do this also. Alternatively there are software tools and (as you've found) backdoor codes.
