I recently changed the screen on an Ipad Air using ifixit parts. Never really had a problem before but now this one Ipad is not showing charging. I am wondering if I accidently hit something inside. Does the Ipad air have the gas gauge that I have been reading about? Or what else do you think I should check out?

Did this occur immediately following your repair? If so, then do a thorough visual inspection around the battery connector, specifically look for FL7500 as it is on the batt_swi line.
