C400 password problem

I have a C 400 latitude I am unable to get by the admin password. I have read many of the posts here to get a leg up on fixing it. After much searching I am at a loss as to the exact location of the chip I need to short out.
If anyone out there can get me a pic as well as anything else I might use It would be nice.
