Hi chaps, Just a Quick one - A friend of mine is dropping his old Aluminium 15" Non Unibody Core 2 Duo Macbook Pro [Circa 2007?] over in a few days. It's gone up the chute and I'm going to have a bash at fixing it, however he's lost the charger. I don't suppose anybody knows if I need to buy a 60w or an 85w Magsafe replacement? Thanks!
