Question: how much does it cost to replace trackpad on macbook air?
Answer: macrumors 6502a Unibody MacBook Pro trackpads are typically around $45-65, I'd say with labor you'd be looking around $150-$175 tops. Take it into the Genius Bar, they can give you an exact quote, minus the tax, for free. Battery replacement should be $129 +tax based on the info on this Apple support page...
