This Mid 2011 MacBook Air is for parts only. 

There is something wrong with, I believe, the RAM on the board. It will attempt to start but then "beep" as a warning there is an issue with the RAM. This machine will not boot. Elected to move the owner to an iPad Air with a keyboard. 

The green itself appears to be good - there is damage on two corners as seen in the images in the listing.

The bottom plate is very clean and comes with the correct screws. The screw that holds the hard drive in place is included but there is no hard drive in the MacBook. 

The battery, from appearances - is good. It is not puffed up or misshapened at all. 

Comes as is - a non working 2011 MacBook Air for parts only.
