I have a Gateway NV7915u model computer. It currently has an i3 330M processor. It is not terribly slow, but I would like to upgrade the processor. The NV79 series computers have the option for i3 330M all the way up to i7 620M. I tried to find out if my specific laptop can be upgraded, but I am unable to find the information. Does anyone know if I can upgrade to i5 520M or i7 620M processors?
