6730b security chip

I've been told that the BIOS Admin password is stored on a "security chip", but does anyone know if or where a replacement chip can be obtained?

You should be able to move a jumper on the motherboard that will allow you to access the bios. It usually is a three pin spot and the jumper needs to be flipped to connect the open pin.

The system board does not have jumpers. I removed the RTC battery (per HP instructions), but the process reset some of the BIOS, but not the password.

Try the solution here, it make sense that it has to be left for a time with no power source.

Thanks, but that was the process that I tried last night, several times. I extended to RTC removal time to 1 hour, but still no go.
 I spoke to HP and was told that the noted process (also in their tech manual) usuall fails, but does occasionally solve the issue. No such luck for me.
The only other option HP gave was to return the computer to them. Min. charge about 90, but could go up to cost of a new system board. That ended our conversation. I'd rather try to isolate the chip and replace it.

as you posted, You can't
modern laptops keep it in a security chip - for anti-theft reasons
resetting the bios does not help;  nor does removing the battery, since the password is not in there
you would need to know in what chip it is, and how to reset that
you have to turn it in to the manufacturer, and show proof of ownership - then they can help
or replace the mobo !
if you want to replace the chip -  you should look for it's model - then you must be able to do some smd soldering to replace it.
as said -  pay the fee, or a new board !
