Honestly mine kind of sounds like what I imagine bones breaking sounds like. Is this normal? Otherwise my Book is 90% flawless at this point, just waiting on a fix for my ~7 hour battery life.
My detach sound varies from really loud to very quiet. Sometimes I think it depends on the angle the screen is at when detached. If its leaning back more, the sound is louder than when it's closer to vertical. Just an observation.
Why does it sound louder if the screen is leaning and there is pressure on the connections. If I position the screen straight perpendicular to the keyboard the release sound is much softer.
