Can you send me the link to that? Because the one I'm looking at and the one your looking at are different. Yet they have the same name.
Unfortunately not, HP's system is generating the pages and doesn't give them unique URLs so if i give you the URL it just goes to an error.
Its in Notebooks > Entertainment > dv6500z > base configuration customise and buy (top right)
The dv6500t is also much the same, see which is cheaper with the options you want, both offer the 8400M for the Graphics.
Edit: This is quite helpful for me actually because I'm probably going to be getting a new laptop soon... current one is an HP btw, and I've had no problems with it.
