System Information showing wrong wattage
I performed this fix on a 85W Magsafe adapter and when I hooked it up to test it, the Power selection in System Information shows that the wattage for the AC charger is 45W, not 85W.
I suspect the L-tip has something in it that tells the Macbook that it's 45W. The wire gauge of the replacement cord is much smaller than the original 85W cord.
Does anyone know where to get the heavier duty cords?
