Changed both speakers

Mi Problema

Speakers were making a lot of screeching noise at anything but very low volume

Mi Solución

The guide was excellent - I was super afraid I will damage something as it's the first time I open a laptop in my life (I assmbled PCs in the past but the last time was 15 years ago

Mi Consejo

- ensure all cable are ABOVE the logic broad before you put it back. I had to lift it a couple of times as I kept forgetting the cables underneath it.

- be patient. If an item is not getting removed or not being inserted with ease then you're probably doing it wrong. Or something is obstructing it. Avoid the temptation due to frustration to force anything in or out at.

- arrange your screws you remove on an A3 paper and write underneath it the item it belongs.

- its ok if it takes a long time. Better safe than sorry. It took me 3h30min to finish it from start to finish.
