I've only had the keyboard/dock a few days, and have only charged it once. But my understanding is that the AD01 might be the repackaged 201 keyboard. The new ones are labeled as "tf700/tf201 mobile docking". But to be certain, with the dock connected, if you go to settings>about tablet and look down for the dock type, it's supposedly will end with "207" if it's the "real" 700 dock, and "206" or something else if it's one of the repackaged old ones. There's a lot of chat about all this keyboard confusion online. Either way, though, it sounds like you should take it back for an exchange.
