  • BIOS password reset please help

    Hello.  I have a laptop that I am trying to erase and re - establish.  It was given to me and it turns out it's a locked BIOS.  Three unsuccessful password attempts gives a screen locked.

    The laptop is a HP Compaq 8710p

    The P/N is #ABA KR886UA

    Any help on this would be highly appreciated.

    K.

    Hi MrToaster...

    I'm sorry that you are having a BIOS password problem with your 8710p.

    Reset the password is quite simple and is covered in Chapter 4 of the Guide Service and Maintenance:

    1. Shut down the computer. If you don't know if the computer is off or in hibernation, turn on the computer and then stop it through the operating system.
    2. Disconnect all external devices connected to the computer.
    3. Turn off the power to the computer first, unplug the power cord from the power outlet and then unplug the power adapter from the computer.
    4. Remove the battery (see battery on page 50).
    5. Remove the battery from the time clock (RTC) (see battery RTC page 80) real.
    6. Wait about 5 minutes.
    7. Replace the RTC battery and go back to the computer.
    8. Connect the power to the computer. Replace any battery at this time.
    9. Turn on the computer.
    10. All passwords and all CMOS settings have been cleared.

    IMPORTANT NOTE: As shown in #10 above, this will also clear the CMOS memory on the computer!

    If you are not comfortable performing these steps, contact HP support for your country / region and they can help you in getting the machine.

    I hope this helps!

    Reset the Microsoft connected account password

    HP recommends using a Microsoft account connected (MSA) to log Windows. With a Microsoft connected account, you log in to Windows using your email address and the password can be reset using a different device at any time. You don't need a Hotmail e-mail address or Microsoft to put in place a connected account. Any email address works.

    To reset your password for an INT account follow these steps:

    1. Open an Internet browser and go to the Microsoft Web page to reset your password : https://account.live.com/password/reset.
    2. Select I forgot my password, and then click reset password.
    3. Follow the on-screen instructions to reset your password.

    When the password is reset, you will be able to use your Microsoft account with the new password to connect to Windows 10 and Windows 8. Make sure that your computer is connected to the Internet until you try to connect.

    For more information on the recovery of your Microsoft account password, see:

    Reset a local user account password in Windows (all versions)

    If you use a local user account HP cannot retrieve or reset your password if it is lost or forgotten.

    HP strongly recommends to create a password reset disk to allow you to reset your password in case it is forgotten. If you don't have a password reset disk and can't remember your password, you will be directed by HP support to restore full original factory conditions and will lose all the data that was not backed up to an external location.

    Create a password reset disk

    To perform these steps, you'll need removable media (a USB flash drive).

    1. Insert your removable media.
    2. Open accounts by clicking theStart button, clicking Control Panel, clicking user accounts and family safety, and then clicking user accounts.
    3. In the left pane, clickcreate a password reset disk, and then follow the instructions. Make sure that you store the disk to reset password in place safe.

    Reset your password using the password reset disk

    If you enter the wrong password when you attempt to log on, Windows displays a message that the password is incorrect.

    1. Click OK to close the message.
    2. Click reset password, and then insert your password reset disk or USB key.
    3. Follow the steps in the password reset Wizard to create a new password.
    4. Login with the new password. If you forget your password again, you can use the same password reset disk. You don't need to make a new.

    For more options for the recovery of your local account password see

    Information about other types of password

    Start-up / BIOS password

    HP do not capture or maintain data BIOS password, if HP is unable to retrieve your local BIOS or password power.

    Laptops, tablets and desktop all-in-one - HP can remove BIOS and passwords via the computer service. You can contact the HP Support to put in place. Options vary depending on the State of the location and warranty (Service fees may apply).

  • Z580 - laptop came with BIOS PASSWORD?

    3 years ago, I bought a lenovo Z580 since m6mobile.fr.

    I've never had access to the BIOS up to this point, because I want to sell this laptop.
    However, there is a BIOS password set, and I never put it. Do you have the dealer set a BIOS password on my laptop, or was it Lenovo?

    If you say it was me, no it was not, unless someone crept into my room and controlled to me which is probably not the case.

    Thank you
