I've googled around and searched here and I haven't seen anyone else with this problem. Weird. So anyway, please help me!

Here's the situation: My TF101 no longer draws a charge from the keyboard dock unless the keyboard dock is plugged into the wall.
Details:
-Running stock unrooted 4.0.3 (latest firmware 9.1.17, US)
-The problem started after the latest firmware update, so that may be related, but it didn't start until several days after the update
-The TF101 still charges just fine when plugged into the wall, as does the keyboard dock itself
-The keyboard dock still works - ie, I can plug it into the tablet and type, use the trackpad and USB ports, etc.
-As stated, if the keyboard dock is plugged into the wall and the TF101 is docked, both the TF101 and the keyboard dock will charge
-When the TF101 is docked and the keyboard is not plugged into the wall, the battery settings say "discharging" and the TF101's battery drains as if it's not plugged into anything.
-Oddly, the keyboard's battery ALSO drains (according to the dual battery widget) in this situation, albeit very slowly, leading me to believe that the TF101 is getting a trickle from the keyboard, but not a full charge.
-The problem started a few days ago and has persisted since then, with no moments of workingness (except when the keyboard is plugged into the wall)

If you need any other information let me know. Thanks for any help you can provide.

My experience with dual battery widget is that it has a flaw in not showing correctly, if you do a cold boot(power button and volume down) it displays properly and the tablet and dock sync for some reason, I will try to pm the dev on this issue.

I am having the almost the same problem, except my dock wont charge at all.

I would like to add that my keyboard dock blinks orange when docked with the tablet and not plugged in. Also it blinks orange when wall charger is plugged in with or without the tablet docked.

I have tried leaving it plugged into the wall charger for 12+ hours with the keyboard docked and again with the dock not attached to the tablet. It never stops blinking orange. Never turns green like it used to. (The tablet will charge but the dock never charges. The dock is now at 0% according to the dual battery widget)

I have heard charging the dock by its self for 4hrs+ on usb3.0 will "wake the dock up" and let you finish charging from the wall charger.
So right now I am trying to charge it by USB 3.0 directly from my computers motherboard but it does not activate the charging light on the dock (docked or not), also the tablet does not charge from USB3.0 anymore like it used to.

Please someone help us solve this!

I love my transformer and use it daily and I am finding it hard to live without the extra battery life the dock gave the tablet.

I solved the problem as follows:

1) Remove table from docking station.
2) Turn tablet off completely.
3) Plug tablet only into the charger, at this point the tablet turned on, and began charging.
4) Allow the tablet to charge completely!
5) Reconnect tablet to docking station, and plug docking station into charger.

Voila, all charged Hope it works for others who have this issue!

Hello all, i am having a similar issue as the original poster. Only my TF101 will not charge while connected to the dock whether the dock is plugged in or not. The dock and tablet charge just fine seperatley and the dock will charge while they are connected.

I'm hoping someone can give me some guidence in regards as to what I should do or try.
