HP Compaq NC6220 and NC6230 BIOS reset procedure [Jun. 8th, 2009|09:04 am]
[mood |accomplished]

I recently acquired a new to me NC6230 laptop.  The only problem was the BIOS were password protected, and I just couldn't have that.  So after some searching, reading (the HP manual sucks) and some trial and error I finally got it right.  Here's the procedure, hopefully it will save others some time.

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. connect 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
when you power back on and right before the OS boots you'll get a message about the date and time not being set, this will go away after the first full boot into the OS

Thanks for that guide man...


Thanks for that guide. I spent probably 2 hours trying various techniques to reset the CMOS on a nc6220.

On every other guide I read they tell you to reconnect the CMOS battery before restarting and it always retains the previous settings. Powering it up with the battery connected sorted it straight away.

Turned an old decomissioned work lappy into a functional little browser for my kid.

Thanks a million, quality guide :)

Accessing the BIOS of Comapaq NC6220

My laptop is Comapaq NC6220.
I am trying to enter BIOS to change the first boot option to CD-ROM.
But I can access only ROM Based Set Up by pressing F10.

I am really thankful if you can explain ,how the BIOS can be accessed in Compaq NC6220.

NC6220 keeps reverting back to power-on pwd prompt

I seem to make the change successfully as I am able to hit F10 after following the procedure. But after power is applied and is rebooted I see hit F1 to enter BIOS setup then immediately followed by the dreaded "Power-Up" password prompt. I can repeat the procedure referenced in this forum but the laptop always reverts back. What's odd is the 2 different BIOS prompts to enter setup (F1 or F10). Anyone have any suggestions? I'm ready to chuck this damn laptop out the window.

Re: NC6220 keeps reverting back to power-on pwd prompt

Take it easy. You tast F10 for enter in the bios-setup.
If you see power-password-window, you make the procedure from this forum.
Whan you stay in bios you go to file/restore defaults, taste enter> F10=yes.
It's ready whithout helpwindows. You go to Save changes and exit.
The laptop is going to windows.
For test make out the laptop. It is restartig automatic. Make powersteker out. The laptop is out.
You reinstall all back.
If you taste F10 by power-on, you go to bios-setup. In the Security-page you kann make the new password or not. Save changes.
It's easy.
Good look.

HP NC6220 still comes up with "power on password" window

I followed the step by step procedure in this thread and still get the power on password window. I let the laptop set for six hours before I powered it up. I wonder whats going on with mine?

Wow, it's been over three years since I posted this. I think it's absolutely awesome it's helped so many people!

I still have the laptop in question, but I can't find the power supply and haven't booted it in about two years, so I'm afraid I can't help the people having problems. My only advice would be to read through the instructions and try again. It took me a lot of tries to get it all right, it may take more than one try for you.

HP Compaq nc6230

Very helpful, thank you.
Problem is, when i attempted to pull the Cmos battery lead from the connection point. It pulled the entire connector right off the board.
:( Very disappointed.
