A question that is on my mind is say you are traveling and your Transformer is about 50% charged and your keyboard dock is less than 50% charged. So you are using your transformer docked into the keyboard, so the keyboard starts charging the Transformer in case you want to un-dock it and use it on the go. Now say the keyboard drains its batter to charge the actual Transformer.....does the keyboard stop working so that you need to undock the transformer and use it that way until you can recharge the keyboard?
It was a thought I had in my head that I don't know if anyone with the tablet and keyboard had tested out yet.
I'm fairly certain that the tablet can use the dock even if the dock's battery is empty. Remember reading it somewhere, but can't find the link at the moment...

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.

Hello
I also had this problem. The tablet drained the docking station dry, and then neither device would charge from the adapter.
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!

Almost same 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.
Ok, new TF700T user here, coming from a TF101. I'm trying to figure out how charging works between the dock and the tablet. With my TF101 it was obvious..when the tablet was docked, it was kept at 100% charge by the dock. Simple. Now, with the TF700T and dock, I see that I have two icons on the bottom showing the charge of each. Nice. But, the charge on my tablet keeps dropping. My dock is at 99% and the tablet is at 90%. Why isn't the dock charging the tablet? What's it waiting for?
I HAVE seen the dock charge the tablet before, I just cannot for the life of me figure out what triggers it. Can anyone explain how it works with the TF700T? Does the tablet have to drop below some % before the dock kicks in or what? Or..do I have a defective dock?
Note that when I plug the charger into the dock + tablet, both batteries charge fine.
The dock is a TF700T dock mislabeled as a TF201 dock, but confirmed to be a 700 by Asus themselves.

Sorry not an answer, but a supplementary. I have the same query and I also wonder why if I plug in the dock the total time available on the battery doesn't change, should it?? Overall what battery time should I expect +/- if I have both connected??

I am strongly suspecting that there is a bug in the software related to the dock charging the tablet. A quick and easy way to trigger the charging process is to simply reboot the dock + tablet combo, not plugged in to the wall...when it comes back up, BING! it starts charging the tablet. My tablet was down to 70% with the dock at 99% and there was absolutely no charging going on until I rebooted the dock + tablet.
My current theory is that something gets fubared when you plug the charging cable back into the dock + tablet combo..when you unplug it, it appears the dock won't ever charge the tablet. I need to test this further when I get home from work.
Ok now I am certain that the dock charging is not working right on the TF700T.
The "reboot" trick does work, causing the dock to charge the tablet...but only to 90%. Once it hits 90%, the charging stops.
Is there some way we can submit "bugs" to Asus? Will they even listen? I'd love to know if other TF700 owners who have the dock are seeing this.

The dock does not charge the tablet before the tab battery is down to about 70%, that is the fact for my TF201 and TF700 and according to what I've read that is the way it's supposed to be (apparantly better for the battery than the TF101 setup).
I don't think your reboot did the trick, I think it would have charged anyways. But I'm not telling you for sure, just saying I think that is the way it's supposed to be (and is for me).
Actually, then the reboot did do the trick - b/c the reboot process consumed enough battery to drop it down under the 70% margin so the dock --> tablet charging process would kick in.
I'll test that and see.
The TF 201 manual states that the tablet will go down to 70% before dock charging kicks in and rechgarges it back to about 99% and then it will stop, go back down and keep doing this, in this way it keeps the tablet charged, the dock dorps to zero at the same time that the tablet gets charged to 80, then the tablet has a nearly full charge for you to use.
And I am drunk, sorry for the typos.
Yeah, your reboot only worked because the tablet's battery fell below the threshold anyway. It charges the tablet at 70% back up to the 90s, then stops, charges again from 70-90%, stops, etc. Your battery usage ends up having spikes, looking like:
_____|\______|\_________ <-- Dock discharges to 0% here
\___
\ <-- Tablets main battery hits 0%
Edit: Formatting got messed up, but I think you'll be able to figure it out

Haha! That's how it's supposed to look! Choo-choo!
I've purchased a TF300TG for a month and the package came with both the tablet and the keyboard dock. Initially I did not use the dock as I did not require that much of battery life, but recently I've started to use the tablet connected with the keyboard dock.
The thing that I'm uncertain of is which is faster:
1. charging both the tablet and the keyboard dock separately
2. charging keyboard dock with the tablet connected

Well charging them together is recommended, if you own two charging bricks like i do you can charge both the dock and tablet separately at the same time.

Sadly I only have one charging brick >< but if charging both of them together is recommended, then I would like to ask something related.
By charging both the tablet and the dock together to 100%, the dock will eventually be squeezed dry by the tablet to 0% while the tablet itself still have plenty of juice left. Do I charge when the tablet notify to charge due to low battery (~14%).
As I read through several forums which stated that letting the battery die completely is not a good practice, is the following method of charging a good method:
1. Charge tablet with dock together to 100%.
2. Disconnect the dock when the dock battery reaches below 15%.
3. Repeat until both the tablet and dock reaches below 15%.
I really liked this about my TF101, but I want a newer model tablet now that the screen is cracked on my TF101, and I don't like the newer Transformers. Is there any sort of keyboard dock outside of the Transformer line that can also charge the tablet using a battery in the dock?
