Password to access BIOS

I was using a boot password on my HPNX9000 laptop. My hard disk failed.  I bought a new one. Put it in. Then decided the boot pawword would be a pain everytime I needed to restart the machine. I entered the bios by hitting f2 in order to disable the password but I could not access the option to disable as it said I did not have admin rights.  I never saw this before!  The only option I had was to blank create a new password that was blank by hitting return in the password field.  I saved settings and exited and now I cannot boot the machine or access the bios.  I have tried the old password and blank, space etc but nothing works.

Any ideas?

Maybe there is something useful on this site?
HOW TO BYPASS BIOS PASSWORDS
Dunno for sure, just found it and I didn't read it very preciesly....

This is a recommended site:
How do I reset a BIOS password?
Lots of people link tho this site and it also has some backdoor passwords (= standard passwords)

Hope it works for you. Best of luck.

I had an HP/Compaq NC4010 and I had a forgotten password twice with two different fixes.  

The first time I tried to reset the bios by unplugging the cmos battery(with the laptop unlplugged) and it wouldn't work.  I ended up sending the laptop in to HP under warranty and they replaced the motherboard.  

Second time:  I unplugged the CMOS battery(with the laptop unplugged) and it completely reset the bios including the logon password.

I don't know what will work, but I would try to reset the BIOS first.

Hi all,

Both of these didn't work. Any other suggestions
Thanks
If this isn't a fairly old laptop, the CMOS reset will not help; the PW is stored in a security chip. Did you set a PW at some time at all, or did the problem appear as you removed the hard drive? If the unit is under warranty, you may try to make them accept a return if the PW appeared spontaneously (as this must be an error in the BIOS or something).

Did you try shorting the bios batter connectors to drain the capacitors? Remove the battery and use a screwdriver/paperclip to bridge the hook connector to the base connector. Don't worry, it won't hurt the motherboard
