Interesting enough RR, I have an iPad 3 and iPad 4 (Retina) and both
show as "Not Charging" when locked and plugged into my USB on the PC.
How would you know? The screen is off when locked. And yes, the iPad will only charge (slowly) from a "normal" usb port when the screen is off.
I little different interpretation of "locked". My interpretation of "locked" is "screen on asking for a pin code", but I see what you mean. Charging does happen at a slower rate with the screen off. Thanks for sharing
