Laptop power on password reset?

[lectrocrew]

This is on my HP Compaq 6715b (in specs). I was making some changes in the BIOS set up and I guess I somehow mistakingly entered a password for 'power on'. Now I can't start the machine because I can't get past the Power On Password screen.
I tried removing the battery on the motherboard but I still get the power on password screen.
I've tried every password I generally use but nothing works. What can I do to correct this?
Thanks,
Mike

Thanks Jason!
That worked fine. I didn't know about the CMOS jumper.

Your notebook has a CMOS jumper?

I found this:
Method for a HP BIOS RECOVERY:

Prerequisite:
The BIOS recovery procedure requires a USB diskette drive and a formatted diskette.
USB pen ----> doesn't work

Download you BIOS from HP, please note the model 68xxx

Copy the bin file of the BIOS on the diskette. eg:68YHV.BIN and not ROM.BIN

Press the 4 arrow keys (up, down, right, left) on the keyboard and power ON.

Wait ~2, 3 seconds an release the keys.

Wait the end of the process ( 2 minutes)
