My A700 was plugged in all day yesterday and never charged up. I figured maybe the plug had become unseated in the outlet, or something, but that doesn't appear to be the case. The charger worked fine on my phone. Plugged the tablet back in and it began charging. Is there any sort of app that might prevent charging? I had my reading app (Mantano Reader) on, but I'm sure I've left that on before while I left it to charge. Maybe an option in Jelly Bean that might cause it? Anyone else experience this? Yesterday was the first time I've experienced it.
