New Video card for a Notebook

[monkey_slap]

My friend just recently got a new HP notebook and wanted to upgrade from her Geforce Go 6150.

I've got a lot of experience with desktops but not with notebooks. I've tried to search on Newegg.com but couldn't really find anything.

Any ideas?

edit: It's an HP dv9420 Notebook btw

doubtful you can upgrade, the chip is most likely onboard the motherboard and therefore cannot be upgraded, unless theres a physical pci-e or a similar slot open

You cannot upgrade the video in that laptop.
