I was hearing a strange buzzing / grinding noise coming from my right speaker. After ensuring it wasn’t the speakers, I realized it was the fan (would only start making the noise when the fans were kicking into high gear). I opened it up and found that one of the screws on the right fan wasn’t attached to the logic board: Step 14, top right screw (orange) attaches to a silver nut (?) which should be attached to the logic board. The adhesive that attaches the nut to the logic board had detached! Gotta find what type of adhesive I need to get for this, but putting this here for anyone with a similar problem.
Followed the guide, took about an hour! The new display works, but one problem: it only shows an empty battery icon with a lightning bolt underneath. Is this a problem with reconnecting the battery?
Worked, took me about an hour! Be careful of step 15, the hinges are not interchangeable.
Having troubles at startup, though — the new display works, but shows me an empty battery with a lightning bolt underneath. I plugged it in to charge overnight, and it still shows the same thing. Did I mess up a battery step?
