Compaq Presario CQ57: bios error 501

What should I do to get rid of this problem?  Please help me someone.

Welcome to the community of HP @ANAKONDA support,

Thank you for joining on the HP's Support Forums! It is a great place to ask questions, find solutions and get help from others in the community! I read your post on the Forums of HP Support.

I wanted to join you and help! I understand that you have a problem with an APPLICATION (501) BIOS ERROR on your Compaq Presario CQ57 laptop PC.

Remove all USB devices. Disconnect all non-essential devices, because they can cause some problems.

Try starting your laptop normally after having disconnected all. If that does not solve the problem, please continue with troubleshooting.

The next step would be for you to try to restore the BIOS. You will see that the document says:

If the BIOS of your laptop becomes corrupted, and a failure to upgrade the BIOS or damage caused by a virus, the computer can display all the following symptoms:

  • The computer displays the error message from the BIOS APPLICATION ERROR 501.

After restoring the BIOS see if you can start the computer normally.

Thank you for your participation in the Forums of HP where we want to help you as well as others who may encounter a similar problem that you have. Remember to mark this message as an acceptable Solution if it solves the problem for you.

If you need assistance, I would be more than happy to continue to help you. Please re-post with the results of the resolution of the problems. Could you please also provide your model number (How can I find my model number or product number?)

Have a wonderful day!

I have a Windows 7 disc, but can not go to the Bios so that it can begin. Help, please! Compaq Presario CQ57-339WM. tried everything. System off Code 71697032

    Hello

    You are welcome

    There is a general policy on the Forum do not provide methods to bypass the Windows log-on passwords, but a local computer store would be able to do it for you.

    Another option would be to reset the laptop to his "factory Condition" and then set it upwards from the beginning - if you do not have a set of recovery media, the laptop are shipped with a recovery Partition which is accessible at the start - that is to say stop the laptop, then start typing away at f11 as soon as you turn on.

    A comprehensive guide on this can be found on the following link.

    2 disable all passwords that are enabled in the Security menu of BIOS.

    3. If the request for current password - enter the unlock code

    4. for the new password, simply press the ENTER key

    5. repeat the same thing to check the password column.

  • Compaq Presario CQ57-445EQ: recovery of the BIOS Compaq Presario CQ57 445EQ

    So I got this Compaq Presario CQ57-445EQ with Windows 7 and 4 GB of ram. Last night I tried to upgrade the BIOS of the first version (2008) to the last (2015) and he got bricks. During the upgrade, it got stuck for 30 minutes and I had to reboot. Now it is black screen, caps lock shift will blink twice every 2 seconds. I tried to recover from USB with sp55356 and sp64612 but no luck.

    I should mention that Win + B, Fn + B, Fn + Esc combinations is not the tone of the laptop, but it shows a USB activity.

    What can I do? Bios versions are .fd files.

    Thanks in advance!

    Not that I know of.

    You may need to purchase recovery media usb to your laptop to HP or HP partner.
