Remove the CM/OS until all the settings drain and reset; it should be instant, however, I've known systems maintain their BI/OS settings for up to 24 hours after the CM/OS was removed.

There are several guides on the internet which show you how to reset the CMOS password. We have a guide at: http://www.binarycpu.com/blog-posts/10132012/reset-your-cmos which explains this process. Hope this helps!

A little surprised to see someone answer this. There is, of course, proper documentation of how to undo this online (like on HP's support website for the nc6220)...

...but there's also literally no guarantee that OP isn't trying to remove the password from a stolen laptop.

All you have to do is remove the battery in the back of the notebook case, try to power on the notebook. See if the notebook still asks for a password, if yes then power it off.
Wait about 10 minutes then power it on again, if it doesn't ask for password then u can switch off the notebook and put the battery back in. And check this link for clear direction.

Hello Friends,

HP Compaq NC6220/6230 BIOS password reset procedure:
1. Disconnect the power supply and remove the battery
2. Remove the three screws that hold in the keyboard on the bottom
3. Up top slide the four tabs on the keyboard closest to the screen towards the touch pad
4. Fold the keyboard over (no need to disconnect it from the mainboard)
5. Using a tiny flat head pry up the power button panel along the edge of the screen
6. Bow the power button panel in the middle of the laptop and gently ease one side up
7. Unplug the connector for the power button panel and remove
8. Locate the CMOS battery in the upper right corner, follow the wire to the left and locate the connector at the upper left corner of the dvd drive
9. Remove the two screws located in the immediate vicinity of the CMOS battery connector
10. Detach the CMOS battery connector
11. Have a beer, sip slow and take at least five minutes
12. DO NOT reconnect the CMOS battery or the laptop battery
13. The power supply and power on
14. Hit F10 to enter setup
15. If you did it right you should get right into the BIOS setup; change whatever settings you fancy, save and exit
16. Let the laptop finish POST then power off and disconnect the power supply
17. Reassembly is the reverse of above

Thanks and Regards
Steven Arnold
