I know this is an old thread....but my latest glitch seems related....in the past few weeks, I have been having trouble with my IPAD charging when connected to the Apple Desk Top. If I dont watch it...it bleeds what little charge is left...down to zero. I am able to use the same charging/connecting cord to the AC plug and charge fully....and the cord is syncing and updating programs properly when connected to the computer.
Could perhaps this be a software glitch in IPAD 4.3.5 update? I also have no problem charging the iPAD using the car charger.
My IPAD is a year old and performs beautifully otherwise.
