samsung rf510 rc510 rv511 rv512 rc512 laptop cpu upgrade DIY

i3 380m to i5 560m upgrade. First, my laptop is a Samsung Sense rc510 s33. but In fact, rf510 rc510 rv511 rv512 rc512 models share the same motherboard. The only difference is the difference in the size of the body due to the size difference depending on how many inches the LCD is, the difference with or without a separate graphic card, and the difference with the cpu model.
