Takes 10 mins

My Problem

Battery had about 540 cycle counts on it, and suddenly couldn't hold a charge for more than 40 minutes or so.

My Fix

Ridiculously easy. Printed out the guide. Followed the steps. I recommend having some canned air to clear out any dust etc. Wiped down the bottom panel with a rag so that probably added to the repair time.

My Advice

This is one of the easiest repairs you could do yourself. You've got nothing to worry about
