Here's the situation: My TF101 no longer draws a charge from the keyboard dock unless the keyboard dock is plugged into the wall.
-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.
