That is a new one on me. I am sure someone will answer your question. I don't know much about the hardware side of things.

Welcome to the forums... We are so glad to have you!

Hi bigkeithj,

Please refer to this thread How to reset or clear CMOS on a laptop?

removing the battery should work, it is the only thing that allows your bios/cmos to hold data, without power.. there is nothing. Unplugging your tower and removing the battery for ~5min should do the trick.

hello people, the hardware side is my strong point!!
 

open up ur tower, on the motherboard u will find the bios chip, beside it is a jumper, pull the jumper off, then put it back on. now ur password is reset..this will work on any computer..

Then you need to practice.. it's an laptop...

I just did this on a Compaq N610c
Remove your Laptop Li-ion battery module.
Then remove the RTC battery for at least 15min.
Replace RTC, and boot the computer ONLY with the AC-Adapter.
Now you can access BIOS, and set hard drive as second boot device.

Hey,
Be sure to have the unit COMPLETELY dis-powered... Unplug not only the bios battery, but the system battery, and any external power. Then hit the power button a couple of times to be sure all the caps are drained. I don't know for sure, but I once had that problem with an old HP, and found that to be my solution. Good luck.

i beliewe ur wrong my laptop doesint have any jumpers, but taking off the litle battery will work
