Have one in front of me.

Remove main battery and ac adapter.

Then remove Bios battery connector located under the space bar for at least 1-2 minutes.

Good luck.

hello

follow this steps:

1) Turn off computer
2) Disconnect AC adapter
3) Remove battery pack, and remove the laptops keyboard
4) Disconnect RTC (Real Time Clock) battery (located underneath the keyboard, the red/white wire)
5) Leave off for five minutes
6) Reconnect the RTC battery and reassemble the laptop
7) Reconnect AC adapter (DO NOT REINSERT ANY BATTERIES AT THIS TIME!)
Cool

Turn on the computer and enter the BIOS by pressing F10
9) Set the new BIOS password and save all settings.
10) Turn off the laptop and reinsert the battery

RTC remove:

if don't work you must need to reflash the bios

A power-on password most of the time will not let you boot from FDD, HDD or USB.

If you can boot from any device you have a good chance to remove it using software.
“I am finding this not to be the case with newer laptops.”

So now we must READ, WRITE or ERASE our way past.

I have a few NC6400’s DUO Core with fingerprint and they are WELL worth saving.

I wish I had more to give but I have not found anything to add.

Please let me know if you find a solution.
