My apologies if this has been posted previously - but I cannot seem to find anyone who has had an identical issue...
My TF201 has worked perfectly since purchased - but in the last 4-6 weeks I have started to notice issues with battery life and as I have been busy with other more pressing issues I have simply been charging it more regularly and 'ignoring' the situation. However I have now realised that the problem appears to be related to the fact that the dock is not charging the tablet from it's battery reserve when the tablet is running low.
I have also noticed that when charging the unit it never gets a 'green' fully charged light on the dock and simply remains 'amber' irrelevant of how long it is left charging...
I have tried the 'cold boot' ('volume down' and power button for more than 12 seconds etc.) - which does initiate the cold boot but does appear to resolve the issue...
I have always charged both items docked and only use the original charger...
I have the same issue which started around the same time. I have also noticed that my dock is not charging although the tablet will while connected to the dock. The dock was at full battery when I noticed it was no longer transferring power to the tablet as the tablets battery got low. Now the dock is around 90% and does not increase regardless of how long it is left on charge. I have tried charging the dock by itself as well; still no luck. The tablet does indicate the dock is connected and the keyboard still funcions. This appears to be an issue with the dock battery being unable to transfer power whether from the plug or to the tablet. Any advise as to what to troubleshoot next would be appreciated.
Just started seeing the same symptoms this week. Guess this device is reaching the end of its road...

I'm having the same issue, too.
I just noticed the same behavior this past week, after having owned the tablet+dock for almost two years with no problems.
The tablet just drains completely whether it's docked or not. The dock is holding a steady 77% charge but does not transfer this charge to the tablet when it's docked. The tablet charges normally when plugged in directly to the wall (using the original charger) or when docked and the dock is plugged in to the wall. The keyboard continues to function normally.
I haven't received any system updates recently either, so I can't think of anything that has changed in the software configuration to make this happen suddenly. Glad that it's happening to other folks and not just me! Has anyone tried a factory reset?
Update: tried the factory reset, but it didn't help.
I found some discussion over on the Transformer Forums, but unfortunately I can't post a link to it. Search google for "transformer forums faq definitive thread battery" to find it.
See for example comments #335, #340, #345-353.
The first post in that thread suggests a couple of things to try, including popping the charger into the freezer (I kid you not), doing a cold boot with the dock attached, and trickle-charging the dock off a PC's USB port. If all that fails, they say to contact ASUS for a warranty repair because it's probably a hardware fault.
I've tried all of those except the trickle-charge, and in addition tried a factory reset. I also opened up the dock, disconnected the battery and reconnected it, and reseated some of the other connectors on the board. Nothing has helped.
My dock is out of warranty (it's two years old) so I suppose that's the end of the road.
Same problem
I have a TF201 with dock that worked perfectly until mid October or maybe early November. After not finding a solution online and talking to ASUS several times I sent in my tablet and dock to have it repaird as they said it was a hardware problem. ASUS wanted nearly $300 to replace the motherboard! I said thank you, but please send it back. I don't believe there is motherboard problem because it is too much of a coincidence that this proble started after receiving the GPS dongle and trying it on the TF201.
The symptoms are
1. the dock doesn't fully charge
2. the tablet will not charge from the dock
3. The tablet will fully charge when the charger is plugged into the dock
Any suggestions are really appreciated. I have done cold boots, with and without the dock.
thanks

Seeing the same symptoms here. Why on earth would they want to replace the motherboard? The tablet appears to be working just fine, it's the dock that's apparently screwed. And $300? Are they out of their ever-lovin' minds? So, were you out shipping one way, or two, if you don't mind my asking?
My solution was to buy a Note 10.1 2014.
Happening to me too:
Post copied from thread I made in error:
After suffering with stock jellybean on my Prime I decided to take the plunge and flash a custom rom.
I followed Matt Hill's guide on unlocking the bootloader and saving my back-ups. That went without a hitch. I then wanted to install the Hairybean 2.3.1 ROM but was still on flatline. I then flashed TWRP 2.5 and then again followed the hairybean install instructions to the letter. I used their supplied bootloader. That also went without a hitch and the Prime itself is running extremely well and I'm loving the new smoothness. When turning the machine on the Prime wanted to update the firmware on it which I declined. When I rebooted, it decided to update anyway. Still. Worked fine and was still silky smooth.
However. I have now noticed that my dock refuses to charge. If I plug the adapter into the dock and attach the tablet to the dock, the tablet will charge but the dock refuses to (even if the tablet is at 100%). I have tried removing the tablet and charging the dock on its own but it refuses. The light comes on the side, but doesn't indicate it is charging. Whats odd, is that when I plug the charger into the tablet and dock together, the widget shows the battery of the dock charges for a second, before then deciding not to. My tablet is at 100% but the dock is stuck at 16%.
Any ideas what might be causing this? Or how I can resolve it?
Thank you!

Facing the same problem. Tablet charges fine while connected to dock, but dock fails to charge. Steady at 5%. It continuously flashes amber light when charger is plugged in. Tablet is out of warranty (about 20 months old), so not sure what to do.
has anyone found a fix for this? mine is doing the same thing dock doesnt seem to be doing its job by powering the tablet really love my prime dont want to have to go and buy a new tablet just because the dock wont charge it.
My wife and I own a TF201 and have found that out of the 2 chargers, only 1 works to charge the tablets now and the other doesn't, and it's all in the actual plug, not the cable.
I've tried a bunch of other android and USB plugs and nothing works to charge them at all.
Have been looking at getting a genuine replacement charger for it so that we can charge both at the same time instead of sharing, but it works for the moment.
You might want to try a new charger too?
Same problem
[Exactly the same problems. TF201 Keyboard won't charge although the tablet does charge when power plugged into keyboard - but to only 99%. When plugged in directly, it happily charges to 100%, therefore the assumption is that the tablet is working fine. The keyboard won't charge at all under any circumstances and it is now down to 43% charge left - Aaaagh!
Crazy thing is that my partner's TF301 is now exhibiting the same symptoms!
I, too, contacted ASUS and they informed me it would cost £45 + VAT just to inspect the 201 and then cost ??? for repair.
Reading the other forum entries it almost sounds as if ASUS have fitted an obsolescence chip!! Just too many coincidences here.
My response: I've recently bought a new ASUS Windows 8 Transformer - I must be mad!
I recently got this same problem, with the classic symptoms:
1. the dock won't charge
2. the tablet will not charge from the dock
3. only the tablet will charge when the tablet is docked and the charger is plugged into the dock
I tried all the tricks I could find on the interweb - cold boots, trickle charging overnight, I even put my charger in the freezer. I even tried a custom ROM (ok, I was planning to do that anyway )
ASUS wanted £45 just to look at it, so I took the plunge and ordered a new dock battery for £30 off ebay (shipped from china). It took a few weeks to arrive, but it has solved the problem! It's a 15 minute job to swap it over, and as I write this, the dock is now charging!!! :good:
If anyone else wants to try it, the dock battery code for my UK model is C21-TF201D. You will need a small phillips head screwdriver and a small Torx star screwdriver to get the dock apart, but it's easy enough. There are tutorials on youtube and plenty of how-to's out there.
So between a battery and a new ROM, it feels like a new tablet again!! :good:
Same Problem + bulging
I have the same problem with my keyboard dock. Now the dock looks bulging in the middle, I think because of the battery. Other functions except charging still works. I cannot flip close tablet and dock attached because of the bulging.
Since the waranty is over, is it possible the dock still works without battery (if I remove the battery)? I'm afraid the battery will explode if I keep using it in this condition. If this is possible maybe I will ask ASUS Service Center to remove the battery since I don't want pay extra money to replace the battery, last time they said its about 85 USD.
Dock registers to tablet, I can see battery level.
Dock Battery is not charging
Dock battery is discharging slowly
It's possible to charge tablet through Dock
I guess something is broken inside so I'm going to open it. I've seen many videos but they are not helpful in this case.
Does someone have experience? Is it possible that battery pack is broken itself?

Yes. I just removed the battery and closed it again without it.
It's look like 2 batteries/cells are good itself but internal controller is brkoen somehow.

I'm surprised there isn't a stickie on this ... it's been talked about here and there.
So I verified I, too, had the power draining problem on my dock ...
- Charged both tablet and Dock to 100%
- Connected tablet to dock, closed the lid and let it sleep
- 8 hrs later, my tablet's battery is at 99%, dock is down to 3%
So the dock's battery has been completely drained while the tablet is 'sleeping'. Of course if I just let the tablet sleep on its own without the dock connected it wouldn't drop more than 5% in 8 hours.
To do a little experiment, last night I POWERED OFF my tablet and connected it to the dock before I went to bed. The tablet was at 73%, dock at 100% then. When I woke up this morning, tablet's at 100%, dock is at 73%.
So it seems like the dock was charging the tablet, and when the tablet's fully charged, it stops draining from the dock - exactly how things SHOULD work! Only problem is this only happened with the tablet powered off.
So seems to me it's a software / firmware problem with the tablet and how it uses the dock to charge itself ... it basically continues to drain the dock even when it's already fully charged.
I do want to confirm if EVERY dock is having the same draining problem? In other words, does anyone out there has a dock which does NOT drain the tablet when the tablet's in sleep?
I will report to Asus but seems like Asus already knows about this issue? And I'm not sure what an RMA would do if it's a known problem that they haven't managed to fix vis SW/FW yet ... I'll get a new dock which will behave the same way?
I guess while filing the complaint I'll wait for Asus to come out with the firmware fix? Hopefully sooner than later. For now the get-around is if I am going to let the tablet sleep for a long time I'll either detach it from the dock or power off the tablet.

The draining issue seems to be fixed for many who got the newest batch (serial # starting B6OK). If you can return yours and buy a new one, it's probably a good idea.
Asus is aware of the issue .. see below

Okay, this might sound stupid. But are you sure your screen is turning off when closing the lid? And by that I mean, when it's fully closed.
Mine goes on again, just when the lid hits the bottom of the dock. You can only see it when it's dark, but I can tell you - it's draining the battery too.
I have the exact same problem too. So I keep them separate at night.
Asus said they are aware and are working on a fix.
So today i got the dock for my TF201.
At first, the tablet wouldn't recognize the dock at all. So i let it charge a bit. Then it recognized the dock (notification tray icon saying that dock is connected), but it showed as 0% battery (weird), then it jumped up to 48%, and the cursor+keyboard worked fine.
I let it charge the rest of the way (both tablet and dock at 100%), and unplugged it and went to the other room. (not on AC power) Once again, the dock wasn't even recognized. So i rebooted, and now it was recognized again, but again reporting 0% battery, and neither the keyboard nor touchpad were responding. So I let it sit again (not on AC), and now it says dock battery is at 100%, although the touchpad, and keyboard still do not work.
Is my dock just defective, or is there something I should know?
(stock ICS, not-rooted)
if wrong section, i am sorry, i'm new here.
Check the connection to the dock...it is a tight fit and its easy to not push it all the way in.....look at the release mechanism it should be set all the way to the right.

I too have had some intermittent issues with the dock. Mine usually occur after it has been asleep for a period of time. I will have to pull it apart up to two or three times to get it to work again. Mine is always recognized but the touchpad and keyboard will not respond. I am thinking about sending it back to Amazon for a new one. I am trying to deal with it as long as I can though since they do not have any in stock at the moment.

yea, now that i have done a full 8 hour charge (RTM actually worked for once ) it seems to be working fine, but that sounds like exactly what i was having.
Now the battery seems a bit off, but that is probably just my imagination at this point.
seems to be working 100% fine now. Strange, kinda just let it charge, and now it works...
Hey, I bought my tf201 yesterday (did the ics upgrade etc) and I noticed exact the same problem when I start testing the dock station. I charged both to 100% and the tab didn't recognize it... Sometimes it showed 0% than suddenly 98%... Sometimes key's did work like turning off wifi, BT. But the letters didn't. touchpad = just dead. Also the dock wasn't recognized when you look in settings > "about phone". I brought it back to the shop, they tried the dock from the one that's in the showroom. And it didn't work either, seems like there's a connection problem in the tab itself. They couldn't give me a new one because all the others were already ordered. And I need to wait 3 weeks for the nex batch so they gave back my money.
This really sucks... The tab on it's own was working well and pretty amazing performance.
So here's the dilemma...
Two days ago, my TF Prime stopped charging via the wall charger directly to the tablet. It recognizes that it's been plugged in however, is not showing the lightning bolt charging.
This is where it get's confusing to me. The exact same wall charger works fine on the dock and charges it successfully and to the same, the dock charges the tablet.
Anyone experiencing this or have any suggestions?

I am having a similar situation myself that I am trying to track down an answer to. My tablet will charge to 100% but does not recognise that it is plugged it. I do not get the "Charging" conformation anymore or even the charging indicator on the battery in the lower right by the clock. My prime is rooted though and I am wondering if it may be a kernel glitch or something to that nature. Odd thing is it was working fine all day then when I plugged it in like any other day this started to happen. I don't even get the conformation DING.

Mine started doing the exact same finally after it started popping up the most annoying battery icon in the middle of the screen making the tablet miserable to use. This was only exaserbated by charging through the dock/keyboard which served to double the size of this same itermittent icon. I'd called Asus support to ask why it was doing this, and as they had no idea they thought it was possibly a hardware failure and recommended sending it in for examination and repair. I am now inclined to agree.
Of course this was only after I'd tried everything else including returning to factory settings, wiping out all apps and data. Soon as I rebooted from clean the icon popped back up proving it was not another application interfering. Only a few weeks later the tablet stopped charging completely except through the dock/keyboard. Before that I'd read on these forums that the OEM charger was faulty and should be replaced, so I bought another with no change. In short, it's not the charger, it's not software, it's a defect in the tablet itself. I purchased a Transformer replacement and am returning the defective tablet being as I've invested in both tablet and dock, but this time purchased a Square Trade 2 year warranty to go with it so repairs will be easier and speedy. I also called Asus back an let them know it is in fact a defect, not an isolated incident, and they should own the issue when customers call. I hope others with this problem will do the same so Asus does not think it's only my tablet and others won't suffer an unsure response. If you can send it in for repairs do so, if you can get a replacement, even better, but I personally took the added precaution of extending the warranty with additional coverage since this happened, something I normally am disinclined to do! Best of luck getting yours fixed, am sorry you got one of the lemons too.
guys,
I just upgrade to .15 and since then, there is no device charging via the wall charger.
I tried to restart it 10 times, tried to plug the power while the device is off and on....nothing.
I read other people have the same issues, but how's the hell I'm solving it?
How do I restore to ver .13 manually?
Please help...its urgent... my keyboard battery almost off, and my tablet battery is on 85%...
Thanks,
Tomer
Did you try to plug it in the tablet and in the keyboard?
Both don't work?
Also I saw this in another thread :
"ANSWER - Simples, reset with a paper clip using the small hole by the SD card in the Tab. Ten seconds. Restart.
Tablet and Dock start to recharge instantly. No problems since. No setting seem to be lost, all Skype contacts, Wireless passwords intact.
Don't panic and don't send it back. Hope this helps."
If what Anthony recommends does not work, try a Hard Reset:
1) Turn off your Prime (while not plugged in)
2) Hold the VOLUME DOWN and POWER button (this takes a number of seconds!) until you get text in the upper left of your screen, then let go (you should see 2 icons in the middle of your screen
3) Just wait at this point until your Prime reboots (you will see a message about Linux Cold Boot, or something like that)
Then try to charge your Prime...
(No data is lost on a Hard Reset)
I would think that the reset button on the side or the factory reset would fix it. Are you rooted?
what does the reset button on the side do? does it completely reset the tablet?

It's the same as a simple restart (reboot), as far as I know, but it can work even when the power button is non-responsive for whatever reason.
Might be the wall plug itself. Mine crapped out for a bit... No idea why, I just had to leave it unplugged for a while, tried it again and it worked. I left mine unplugged for like 12 hours. Not saying that's like the minimum for it or anything, just how long I gave mine before trying it. There's a thread on here somewhere about peoples chargers crapping out temporarily. Some put theirs in the freezer for a while and such lol. I'd recommend looking that up and giving it a read, it might help you before you end up wiping your tablet clean or sending it to Asus or something.

He can prove its not the charger itself if:
When he plugs in his dock to his tablet, the Dock shows X% of battery left.
Then plugs in the dock to the charger for a while, then plugs it back in the tablet.
If the dock has a battery % greater than what it did initially, then the charger is working.. Otherwise either BOTH the tablet and dock stopped charging coincidentally, or the charger is broke
the rest hole next to the MicroSD solve the issue.
Thanks guys.
appreciated!

Well I updated this morning and mine is not charging. Tablet charged fine last night overnight. Here is what I have tried so maybe someone can add any other tests that I may have missed. (no dock)
Tests and results:
- I have tried multiple outlets in my house. No charging
- I can charge a nook tablet with the Asus brick and that charges fine
- I can transfer data back and forth with the data connected to my laptop
- With the Prime off and cable connected to the brick or laptop and then connected to Prime, Prime starts up, so it looks like it senses the connection.
- Did a full data wipe and all tests done with Prime at default mode; nothing. Also did a hard reboot; no luck.
- Tablet seems to charge very slowly (although no indication that it is charging) when it's plugged into the Asus brick or Nook brick and then shutdown.
I just put the Prime charger in the freezer for 30 min to see if that helps. I had to do this before with my TF101 when I had it. I can't see it being the cable because I just left it overnight last night to charge plus I don't a spare one to test with.
The Nook brick doesn't charge the Prime when on (will test this out when the Prime starts charging correctly; would make a great alternative charger)
Even though it looks like is can charge will completely off, that is a major inconvenience and an RMA should fix that.
So, this was my mothers tablet and it stopped working one day. She hadn't used it in a while and it was simply under her bed. After a period of no use she pulled it out and tried to use it - didn't work at all. Plugged in = no response, etc.
Friend has same tablet, same charger, etc. Tried his charger with her tablet, nothing. No charging light, no indication of response of the tablet whatsoever.
Tried the long-time trickle charge using a lower power charge, left it charging for days on end. Still nothing.
Tried replacing the battery and the charging port/ribbon, still nothing. Left to trickle charge again and still nothing.
This was all many months ago and she has since given up and purchased a new tablet. I thought of a good use for this TF300 if I could get it working so figured I'd try to fix it. Is there anything else I need to try before I just go ahead and replace the main board? It's only like $30 on ebay so no harm done if it doesn't work.
