Hi,

Does anyone know what this chip is?

Thank you,
James Pedersen

This is from the motherboard of my 13-inch Mid-2010 Unibody MacBook Pro laptop.

The reason I ask is that I am thinking of replacing it on the motherboard.

I should note that it seems like the same sort of chip as this chip, also on the same motherboard:

Thank you,
James Pedersen
