Just wondering if anyone has experienced the following issue:
I've tried charging the TF from the dock with the lid/screen down.. when I lift the screen to check some time later (say an hour or so) - the charge doesn't appear to have increased. When I unlock and go to the homescreen, the lightning bolt has disappeared - only to appear a few moments later, presumably to signify that charging has resumed.. Its a UK TF & Dock, therefore no new firmware yet.. Is this happening because there's been one of the infamous "dock disconnects" at some point during the charging phase?
Tried my second test this afternoon - left WiFi to always on, but put the TF in airport mode this time.. same "pausing" of charging... My original post from last night's weirdness below:
----------------------------------------------
Question here for anyone who can help shed some light on what's going on..
If a Dock is fully charged, and a TF is almost depleted (e.g. 1-4% charge left).. will the dock fully recharge the tablet to 100% or near enough?
The reason I ask is because I tried just that scenario last night.. made sure the doc was fully charged (leaving it plugged into the mains) and then docked my TF into it when it was at about 2% and removed the mains... shut the lid and left it..
Some time later I popped open the lid and checked, it was up to about 49%... so I closed the lid and left it over night...
And here's where some weirdness started happening..
Checking it this morning by lifting the lid, the tablet reported the same charge value of 49% with no lightning bolt in the notification area.. a few moments later, the lightning bolt appeared and it continued to charge from the dock and checking the battery usage graph confirmed that it had only charged to a certain point and simply stopped. With the lid open (but screen off) the tablet continued to charge off the dock upto about 62% at which point the lightning bolt disappeared and the dock light was flashing orange...
I'm on a UK tablet and dock (so no new firmware update yet), and I have the "WiFi off when screen off" mode selected - not that that option should have any affect (the wifi was indeed off all that time the screen was off - but so it seems was the charging)
I don't think I've got a duff dock, but can anyone confirm they've experienced similar... that the dock doesn't fully recharge the tablet or offer some other explanation plz?
--------------------------------
It could be the dock disconnect issue. Mine used to disconnect when it was locked, but now its fine after the update.
Just to be clear, your charging it using the wall adapter correct?
Charging the dock via wall adaptor, disconnect it once fully charged.. docking the TF and seeing how well the dock charges the TF on its own..
I tried putting the WiFi back to 'always on' with Airplane mode off.. and surprise surprise it seems to be charging with the lid down and screen off.. wake it up, lightning bolt still there and still charging.. some how the wifi power saving mode must be linked.. dock disconnects probably also an issue.. any thoughts?
A few thoughts.
The dock can only charge the pad to about 55-60%. This is listed in the specs.
When doc with pad are on the charger the pad will be charged first and then the dock. This is by design.
What is up with the UK units not getting the OTA that fixes most of the dock issues (Wifi, sleep, etc)?
I have been charging my dock and tablet together since I got it, which has been for about two or three chargers, and I have the latest firmware updates. What I noticed is that my tablet was at about 78% and the dock was blinking orange, indicating that it was less than 10%. I plugged them both in and in about 3 hours the dock light turned back to green, indicating that it was charged, and my tablet shows 100% charge with no lightning bolt, meaning that the dock isn't charging it. What surprises me is that the last time I charged it the tablet stayed at 100% for quite some time but then the dock started blinking orange again. From what I have read and understood, the dock isn't suppose to charge the tablet until it reaches a certain perentage, but apparently the dock is charging the tablet even when the tablet is somewhat fully charged. I'm going to see how it acts this time around and see if we can get to the bottom of the issue of how the dock and tablet are charging together.
I am assuming that you are having a problem with the dock and tablet not charging together because you have the disconnect issue, which should be fixed once you get the latest firmware update.
Well that 60% charging tallies with what I've just witnessed... the dock charged the tablet to 66% before giving out.. but I had to put the TF into "WiFi always on mode" before it would charge with the lid down (compared to the "charging sleep" that I was experiencing in either Airplane mode or "WiFi off when screen off" modes)
Wonder if that's been fixed with the firmware update.. can anyone with the update confirm that the tablet will charge in those other WiFi powersaving modes?

I've never had any problems with charging before until today I finally found a keyboard dock for my Asus Transformer. I plugged it in and tried to charge it but it was not charging. Then I unplugged the keyboard dock and my tablet itself would not charge. Did docking the tablet cause this problem (maybe the update it installed upon plugging it in) or is it a coicidence that my cable just stopped working. Either way I'm freaking out!
I may have the same issue or a simiar issue before with the charging but later I found out it wont charge when it at a certain percentage. Basicly if the % around 95 then it wont charge but for example you at 70% then it should start charging again. i would say it like a preventative measure to prevent over charging. If that was the case then this should be the reason.
On a side note I recommend dling dual battery widget so you know how much batter your dock have and tablet so you will not be charging it all the time thinking it might be out soon.
Just got the dock a few days ago and it charged up fine the first day. Then a few minor glitches started.... the tablet wouldn't wake up from keyboard input or trackpad input. Now, the dock wont charge at all.
Dual battery widget shows it at 0%, and when I apply the charging cable, the LED shows green (when the tablet is at 100%). So it's almost as if it doesn't even see the dock battery.
Any ideas?
UPDATE: This issue has been SOLVED! See post #3 for my solution.
If you just got it, then it is in waranty. I would send it back for repair since they will replace it with a functioning one. My dock did this (although it was, like, a week after my newegg waranty expired) and I sent it into asus and they replaced it in a little under 5 days.
On a side note, have you tried removing the transformer, waiting about 10-15 seconds, and then replacing the transformer back on the dock (while the dock is not charging). Also, does the transformer show it is charging when you put it in the dock with under 90% charge? The dual battery widget sometimes says I have no charge on my dock when I clearly do. To fix it I just remove my transformer from the dock, wait a little, and put it back in aaaand: voila, it works perfectly.
Oh yea, and try disabling "power saving mode" in the settings under input if you want to wake up your tablet with the keyboard or trackpad.

Dyskmaster,
Thanks for the tips. I tried all of your suggestions, and nothing worked. The weird part was - every time I plugged in the dock, the light displayed solid green (indicating 100% charge on both batteries), but dual battery showed 0% charge on the dock. This got me thinking that the dual battery widget was not reporting correctly.
I then found a tip on another Android forum that suggested plugging in the dock to a USB port on a PC - waiting 5-10 minutes - and then trying the AC wall charger again. I did this, and boom.. the dual battery widget showed 100% on both batteries.
It's been working fine for about a week now, with no repeats... I have no idea what the problem was. My only guess is that the dual battery widget freaked out the first time the dock went to 0% charge. It seems it's reporting fine though now, even after the dock hits 0%.
I have this problem too, the led in dock always blinking in orange and dual battery always shows 0% ( of Dock) and i also changed the charger and changed the roms , but still not charging, what should i do?
Fixed for me too
I had RMA's my TF101 as it had completely died on my following ICS upgrade, Asus returned my tablet with ICS 4.0.3. For around 3 days I was using it very happily, no more reboots, no screens of death, I was so happy.
Then one morning after recharging my tablet while docked, I checked the dual battery monitor and it showed the dock battery rapidly fluctuating from 100% to 0%, it would show fully charged when plugged into the wall.
I was about to RMA the keyboard when I saw your post, plugged the keyboard into my laptop USB, left it probably 5 mins, then attacehed the tablet, dual battery widget showing both batteries correctly and no flucuating readings.
Thanks again

When you plugged the dock in to the usb, did you get a light on the dock? having the same problem!
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.
Same Problem

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.
My cable broke, and a friend gave me his (from a TF201). It charges my tablet, both docked and undocked, but it doesn't charges te keyboard. The energy passes through the keyboard to the tab, but the keyboard itself doesn't charge at all, it's always on 0%. How can I make it charge? Thanks!
[Ignore my poor english]
Sounds like electronic in your keyboard is not working.
Sent from my Meizu MX2
If you let your dock battery reach 0%, it might never charge again, you should never let them reach 0%
You can try opening it, there is a small switch on the board inside, flip it and try charging for an hour, then flip it back and try charging fully
I did it once and that worked - might have been coincidence though
Have you tried charging the dock without the tablet attached? Mine did the same thing until I did this. I just waited until the little light on the side went green. Works fine now.
Yep, i tried everything. I'll open it tomorrow to check for that switch *Detection* talked about. Thanks!
Have you tried charging just the dock trough usb for 30 - 60 minutes?
I once had the dock @ 0%, wouldn't charge on the net charger, but after "trickle" charging trough usb for ± an hour further charging on the net adapter worked.
Hello i have a problem with the tablet dock
The tablet was just stored for a long time and i got a new charger because i lost the old one, the tablet works fine but the dock stays at 0% no matter what
i flipped the switch inside the dock like once or twice a day over a week but its still at 0%
I have switched the battery from the tablet wich was at 100% to the dock and the tablet got charged like no problem but the dock it still not charging, right now its at around 80% it got discharged a little over some weeks .
The keyboard works with no problem its just not getting charge or charging the tablet when docked but if i connect the charger to the keyboard while docked it charges the tablet
I hope someone can help me
Sounds like the charging circuit is fried in the dock if the battery charges fine in the tablet

is there any way to test it that you know?
Buy a new charging board and replace it
Other than asking someone with a lot of micro-electronics knowledge to test it, that's the only thing I can think of
They are so cheap now though, it would be easier to just buy another one, you can get both tablet and dock on ebay for £99, or the dock for around £40
Usually when they are stored for a long time, the batteries drain and once they hit 0%, they won't charge again, but if you say that battery still works fine in the tablet half, and the dock can still charge the tablet, then it sounds like it's the actual dock charging circuit at fault, can't think of anything else other than connections being loose between the battery and the dock
The dock battery not working properly
Hi, i have Transformer TF101 (KTU87Q KaTKiss-4.4.4_036) after some time the battery in my dock stops working (icon dock battery display still 0% and red exclamation mark)and while charging the battery dock is still flashing red light. I replaced the battery for genuine type, battery can be charged (green light while full charging - OK) BUT when I turn on the tablet, then some time icon shows 0% and red exclamation mark after that for example 96%, when the tablet battery is discharged, transfomer shuts down and the icon dock battery still display example 94% What is wrong?
I made a battery calibration but nothing has changed.
Why new replaced genuine dock battery not working?
Thank you

I recently had a dock that had the same problem. Everything worked fine except that it would not charge a known working battery. Make sure that you have the switch in the correct position. From what I recall, the switch has markings on it that show in one position "0" and the other "1", similar to a power source switch on a desktop computer. You want it in the "1" position.
Also, does the battery indicator light come on when the battery is less than 90% and you are connected to the charger? Are you using a OEM ASUS TF-101 cable and power adapter?
It may be that the dock has a hardware problem in which case the only thing that will fix it is a new board. Not really worth fixing as this is now 4+ years old and there are many devices that can be purchased brand new for the price of fixing the dock which are vastly superior to the TF101.
