I gave my girlfriend the new 2011 11" Macbook Air and whilst she was doing some kind of craft work, managed to drop a very small piece of paper which she describes at about 1mm x 2mm in size (think something smaller than a hole punched circle) onto the track pad. In brushing it off, she isn't sure if it brushed off the Macbook Air or inside the enclosure (where the 'button' on the glass trackpad is). She can't tell if it's in there or if it went elsewhere since there's lots of small pieces of paper around. She tried shaking it but nothing came out. So my question is whether there is any implications for the paper going inside. Looking at the photos on Step 13 of http://www.ifixit.com/Teardown/MacBook-Air-11-Inch-Model-A1370-Teardown/3745/2 , it does look possible for a piece of paper to slip inside and fall into the insides. My guess is probably not because the keyboard/trackpad presumably has an undercover tray of some form to separate it from the key components (i.e. logic board, etc) such as in the event of spilling food/drink, or just general dust accumulation and hence the tiny piece of paper would get caught there. Any thoughts?
