Questions.. 1) Is there a way to clean out the dirt/dust that has fallen through the holes in my speakers? 2) I have a few dead pixels that are just black.. I have apple care and there is no damage to my screen at all. They are not scratches or anything I have inflicted. 3) My screen can no longer stay half way shut, it doesn't hold itself up anymore, it will just fall once it gets to about halfway, can Apple fix this? 4) A screw at the bottom of my MBP is missing, wtf!
