Hello all.
I was wondering if there is a way of manually allowing this or not.
I was on a older version of the Crombi rom which seemed to allow this to work.
I have since updated to the latest and tried a few other different roms and it will only seem to charge out now it the tablet/dock is open and screen is on.
I would be fine if it would charge even if the tablet is open but screen off.
There are times where I only have the charger for the tablet and can borrow a usb cable and I became accustom to charging my phone that way.
Any ideas would be greatly appreciated.
Thank you
thats a bit strange, as I can charge both the tablet and dock together with it shut on mine..
does the dock charge by itself?
does the tablet charge by itself?
does the tablet accept charge from dock when Tablet is plugged into dock and shut?
(easy to test this one.. check % before and after on both and compare... say after 1/2 hour and see if there is a difference...as Dock should discharge in to Tablet, then stop once tablet is full and then you should only get deep sleep lossage....)
Yeah the tablet and the dock all charge okay.
I was trying to use the usb from the dock to charge my phone while it's closed.
When I'm out I watch stuff on the tablet and charge it and go to sleep and close the tablet and dock. But when I do that, it stops charging the phone I have plugged into that usb connection on the dock.
Right..understand..
The dock is going into full shut down/tablet is going into full shut down
..which most of us want.. This will be kernel based..
As while it would be good say on a long trip to be able to use the dock as an external battery top up device for phones..I don't think the Asus docks have ever been that smart..
Only thing I can think off is that you set WiFi to always on..thus the tablet is not going to go into the deep mode for some time after shut down..
You could ask in the grimlock kernel thread on the setting in the kernel on the expected time that it is set...
Okay I'll give that a shot.
I am already using grim lock anyway

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.
You should post your results here

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.
I have the 16 GB WiFi version for Christmas with the keyboard dock... before I rooted I would leave my tablet on the dock overnight, but it will shutdown during the night and I have to press and hold the power button to turn it on. I tried rooting it and no avail there. I tried charging it straight from the outlet, and it works perfectly fine. The only way my tablet won't shut down if I am streaming a radio station through Winamp. So is there any fixes? (Running on GALAXY TASK 11)
any answers?
So if you plug it directly into the wall outlet it doesn't turn off? On the keyboard dock it shuts off? I would guess that the GT isn't recognizing the dock as an AC charger like being plugged into the outlet does. There might be a work around such as force charging from usb. Do a search for that and set it up. Let us know if it works.
Just my guess though. If you can't find how to force usb charge let me know and I'll get the process for you. just don't know of the top of my head. It's somewhere around Pershoots kernel thread I think.

When I connect to regular wall outlet it would not shut down. If I dock the tablet to the keyboard, without the dock being connected to the wall charger, It wouldn't shut down. However if I connect my charger to the dock and I dock my tablet, my tablet would shut down by itself after a time of inactivity. So my question is how to charge it on the dock without the tablet shutting down. If you think that you think that foce usb charging maybe the fix... pleasePM me because i am extremely busy with school work
also it can still charge...its just when docked...it will turn off by it self.
I have had the same issue exactly, and even went back to the shop to exchange first the keyboard and then the Tab itself. I still had the issue. I finally decreased the number of instances this happened, but did not fully solve the issue, by going to overcome rom. I would welcome anybody with a final solution though.
I know that the ics rom works fine...but thats an obvious answer.....but i actually use the cameras
I have the same problem. The Tab seems to shut off when it reaches 100% charge in sleep mode while in the keyboard dock. If the Tab is active, doing something such as playing music in Pandora or a similar activity, the Tab does not shut down, even if the charge level shows 100%.
In another thread, someone posted that they thought that this problem could be related to 3.2 because it does not occur in ICS or 3.1. Whatever the cause, I am looking forward to finding a solution. I have stopped using the keyboard dock as a charging station due to this issue.
Bob
is it possible to find the problem on 3.2 ..and replace it with the 3.1 version...and make them do the "forbidden dance"? (noob status.. right here)
I had the issue on 3.1 as well.
I had the same problem on every 3.2 rom I tried. It didn't happen on any 3.1 builds and it hasn't happened on the cm9 preview.

Bump! Does anyone know how to really fix this? and are we going to face this problem on the official ICS?
Yes, also on ics 4.04 I have the issue. Now it is 100% repeatable.
tab on mains ---> fine
tab on keyboard (either witout power or on pc usb) ---> fine
tab on keyboard on mains ---> hangs!!
Agreed. But when the devs get the camera working on JB maybe it wont happen on JB... maybe its a touchwiz or camera problem
Samsung Tablet 10.1 Shutdown when docked using ICS
I have experienced the same issue with the Samsung Tablet 10.1 32GB WiFi only using ICS 4.0.4. when docked to the Samsung keyboard GT-P7510. The tablet will freeze randomly when docked. It does not matter if plugged into power or not. If the screen goes blank, you must hold the start button down for 20 seconds to get the system to reboot. The system is not going into sleep mode. It is turning itself off. This random shutdown issue is annoying. Has anyone determined how to fix this issue? Should a bluetooth keyboard be purchased to solve this problem?
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.
I left my tablet in my car, in my backpack, away from the sun. It still managed to get some heat over a few hours and when I turned it back on it turned off after a second. After cooling it and connecting my charger it started working again.
Here is where it starts getting weird. It won’t charge. It says that it isn’t charging though I know it knows there is a charger connected. Every time I insert the charger it gets out of sleep, but no charge! What is even weirder is that the dock won’t charge now either. The tablet still recognizes the dock as well and I can type but it’s not very useful if I can’t get it to charge.
The charger was not in the car so there was no damage to that. I don’t want any feedback about what I should have done as I can’t afford another one so that would be utterly useless. I know that I shouldn’t have left it in the car in the first place, no need to mention it.
The Prime might have become totally discharged. I'd suggest trying to charge them for 24 hours...Plug them in and leave it alone and see if that solves the problem. Just to be sure there are no interaction problems, I'd suggest that each be charged individually.
Good luck,
Bob
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?
