CF-31 upgrades...

Hi,

I currently have a CF-31 MK1 with a i5-540M.

Is the cpu upgradable or soldered to the board?

Max ram support?

If it use the Socket G1, will it support a higher dual core (i7-640M or even a quad core Core i7-940XM?)

Thanks!

EDIT: anyone with service manual? Can't find any for the CF-31 , i've seen one with part list only.
