CPU suggestions for new motherboard

Hi!

I purchased a new motherboard for my laptop, an HP Pavilion dv6700:

HP Pavilion DV6000 Series Intel Motherboard
HP Part #: 460900-001
Image is attached

I need a dual core intel cpu for it but I don't know what is compatible?
The purple socket has: mPGA 478MN written on it.

Thanks for any help!
