Hi,

I have a hp Elitebook on which I ve put a password. Still know the password but want to remove it, however I don t gave this option.
Updated to latest bios version but still the password is there. Also resettd to default in bios but no change. Seems as if it doesn t keep the changes.

Please advise.

This is your laptop I assume :)
Well, if you want to try this:  You have to remove bios battery once. after remove start your system enter to bios its all resetted. switch off system and put bios battery and restore default setting for bios

Also the following site provided some HP solutions that may fit your case here:

As far as I read removing battery does not help.

If you try it and it does not work, can you specify the model of your computer and user name listed when you attempt to enter BIOS?
As far as I know, you have to use "HP Sparekey" (if enrolled).
If the user name is "BIOS Administrator" and the password is lost, and if the BIOS version is later than March 2008, contact HP to have it reset.

If the password wasn't registered, or you are not the original owner, there is nothing you can do to retrieve the password, or clear it.
 
You will need a new motherboard, or you can strip the notebook for parts (except for the motherboard, which is useless as it is).

It won't - the password is stored encrypted in non-volatile RAM on the motherboard - otherwise how secure would a laptop be if you only had to remove the battery for a few minutes to get into it?

Removing a password on the Elitebook isn't intuitve you actually have to change the password to blank, there is no remove option.

Enter the BIOS using your password then set a new password, use the known password as the old and leave the new password and repeat new password fields blank.

Now, last resort if you want to give it a go:
Go to F10 to remove and add the BIOS user again
Login using user... as Guest User
Security to defaults.  
Save and Exit.

[MASQ edited out "the disk that cannot be named"]

That's all I got..hope something works!

If you are talking about a windows logon password, go to users and remove it
Start, Control Panel
User Accounts
There should a REMOVE password link under your account info

OK, specify this:  Is it a BIOS password or a WINDOWS LOGON password?

@ janhoedt can you change the password?

@ xtermie please don't post that particular boot CD - it's not allowed on this site.

@ xtermie - That disk contains a (pirated) copyright version of Microsoft's mini-bootable OS & while that continues the EE stance is that we can't support it here so references to it will be removed.  Earlier versions also had several pirated apps as well but that's now improved so the content is free/share/trialware.  Hope that helps explain.

did you try entering your password - and input another - blank password?  blank = Enter

@janhoedt
There still seems to be confusion over whether this is a Windows password or a BIOS password.  If a BIOS password try changing rather than removing it.  If a Windows password it can be reset with a boot CD but we need to know which kind of password it is to guide you accurately.

jan  - were there any results, or errors?  what happened? why don't you post that info?  we have to tear each word out of you...
sorry, but without you posting info - we simply don't know zilch
the correct procedure is : you give info - and we react, besed on that info, to come to a conclusion
without that, it is impossible

Sorry for late response, I was quite busy with other incidents.
You can close this case. The input you gave was interesting but didn't help me.
No errors, no results with any step: resetting to defaults etc. It (bios) doesn't keep the settings after reboot and asks password.
Never mind for me, I don't need to be in bios that frequently and I can enter.
So thanks for all the input, but you can close the case.

That's helpful
Sounds like you have HP Security Management enabled which protects the BIOS password
See: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&objectID=c01798858&jumpid=reg_R1002_USEN
To switch it off and lose any cached passwords.

See the following link for how to close the case
