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.
Hi all,
I have an AT&T Samsung Galaxy S 2 (i777). It was rooted and running CM 10.1. A few months ago it started to have charging/USB port issues. Some of the symptoms:
-Sporadic charging (starting and stopping)
-Required USB jiggling to get it to start charging
-Sometimes wouldn't charge at all until it died, then would eventually charge while powered off
-Would not shutdown (only reboot, even if the battery was removed)
-Randomly started "car mode"
My initial thoughts on this were USB port issues. After doing some research on people with similar problems, I tried cleaning the port with alcohol, toothbrush, compressed air, etc. No avail.
Eventually the phone just stopped charging altogether. At this point, if I left it plugged in, it would sit in a continuous boot loop (boot, get to lock screen, realize it has no juice, shutdown, rinse, repeat). After a few days of attempting to charge and just having that happen, it went black and has never turned on since.
To try to solve that, I bought a new USB port flex cable on eBay and replaced it, assuming this would solve all my USB port issues. I tried to be as ESD safe as possible and also not break anything in the phone, but after replacing the board, it still wouldn't boot.
Next step- bought a new battery with an external charger to skip the USB port altogether and see if the battery was shot. Charged up the new battery, popped it in, nothing.
I'm at a total loss. If it started as a charging problem, I don't see how the problem could have been anywhere but the flex cable board or the battery. Does anyone have any ideas about what might be going wrong? I would REALLY appreciate some insight.
Thanks!
Maybe the repeated loops damage it

Did you ever find a solution? I'm in the no charge boot loop after letting it die last night.
I have not seen previous usb problems at all. I suspect that my battery got over-drained, but then I've got the same symptoms as you and you have a new battery. I can get it into recovery but t won't stay on in CWM for long enough to fix permissions, which is the only thing I've tried so far in CWM.
Thanks
If i was in your place i'd have taken it to the nearest Samsung Service center and let them fix it for me.
I think the fluctuation in power may have damaged your phone battery point from where it takes power from the battery and charge it.
Maybe it has damaged the motherboard.
We cannot say anything in this situation.
You should just take it to your nearest service center.
Best of Luck
OK, wiping Data fixed it.
Thanks for your reply. This problem just started this morning with no previous issues, doing the looping part of your problem that I quoted. so it's not a question of what I might have done.
But, for others encountering my part of it, here's what I've done and learned so far today.
As I looked into things elsewhere on the , it seemed to be a software problem. Luckily, I have another Galaxy (Exhibit) that's similar battery and I was able to put the charged battery from it into the SII. The SII booted and worked fine but did not charge. I put the SII battery into the Exhibit (sorta fits). It took a charge.
This confirmed to me that it's not the battery. It must be the phone perhaps USB port or more likely "firmware" since problem started abruptly after draining battery down.
I then wiped data on the SII from CWM/recovery and rebooted.
SII is now charging again. Stock battery is back in and working.
Time will tell if all is well, but here's what I think happened:
1) battery drained down to zero while unplugged
2) plugging in and starting up phone immediately threw something off in the battery stats at a low level...that kept it from charging even when turned off. Or rather threw it into a loop. Don't really understand this stuff, but may have to do with physical things that happen in a battery when the cells drop down way low and then the voltage feedback they give to charging circuit.
3) charging battery in another device (gingerbread, by the way) got the battery out of this, if battery had been a contributing factor,(or just a trigger) it was back over the hump.
4) wiping data fixed the charging, so I conclude it was a charging circuit data issue triggered by an ultra low battery.
Hope I'm over this problem and hope that it helps somebody else. If you run into this yourself with no previous USB or hardware issues, I'd suspect software before hardware. If I had only one battery and no way to charge it externally, I would suggest get one of those simple universal clip-on chargers to bring the battery back up and then go into CWM and wipe data.
UPDATE: It's stopped charging again. It's no longer looping since I got the battery charged up, but not right either. As soon as I plug it into a USB, it boots itself without powering on.
I guess that this is looking more like a physical USB issue now. Weird that there's been no previous sign of trouble before today.
UPDATE2: I cleaned USB port but no help. Then I bent the USB contacts towards the screen and it is charging now again. I'm ordering a replacement USB.
I should add that I'm running Shostock Jellybean, older (not current) version with it's associated Jeboo kernel. Don't know if it matters.
I wish I'd seen your post sooner.. I had exactly the same problems back in January. Took all the same steps you did. In the end, an 8$ USB flex cable from EBay solved the problem. I think you'll have luck with that:thumbup:

hey, I'm experiencing the same issue slightly different.
-Sporadic charging (starting and stopping)
-Randomly started "car mode"
-plugged in the charger while the device is switched off, it automatically turns the device on.
-If the cable still plugged in while the charger removed from the main current, it shows "Charging stopped. High voltage"
-From yesterday, it doesn't charge even. Only way to charge is, connect the charger first and then Restart the device.
Then only charging continuous.
Can anyone help to solve this? Is this a software issue?
Thanks!

Also, there was this issue early --> when I charge it from the laptop, the USB mode doesn't switch on. It just charge the phone only.
But now it's not even working like that.

hi, my s2 wont charge. It just shows up charging when plugged in but it doesnt charge at all. and it overheats too much while plugged in. What is that flex cable you said, is it the one that connects the charging port to the motherboard? were you the one opened and replaced it? thanks
Hey guys, it's been awhile since I asked a question, but here I am, lol.
In a nutshell, I'm pretty sure something in my device (hardware) is fried, but I thought I'd see if anyone knows better.
The problem is my device seems to be sending power out of the usb port, and doesn't connect to the pc or recognize it is charging correctly.
This also applies to download mode (windows says device has malfunctioned) and when powered off (there is no battery that shows up when plugged in). In order to power back on after turning it off, I have to remove the battery, then reinsert it while holding down the power. I can't think of much that could have caused this, other than I was visiting places with high humidity levels. One unusual thing that happened before this started was my device rebooted into safe mode when playing bad piggies. That was really weird since I have tried booting into safe mode before, but thought samsung must have disabled it for some reason. I have already tried wiping data and flashing a new kernel/rom. Obviously I can't re-partition since I can't connect to my computer in download mode. What do you guys think? I think it is time for a new device.
EDIT: I should mention that it started behaving normally yesterday for about 5 minutes, but then it went back to this.

I'm 99.9% sure that under normal conditions that an Android device should never power the USB port. Source of speculation. If it is indeed powering the USB, then you've either got a really wonky firmware installed, or some sort of hardware issue. I'd try to make sure that it's sending power out before going further (especially if you can't charge it, the battery will be dead soon). After this test, I'd keep the battery out for a while, just to be sure it's not going to short anything.
One thing I've noticed in my tinkering is that taking a device apart, then putting it back together again can mysteriously fix problems (although 75% of the time the fix is temporary). If you suspect water damage, opening it up and letting it air out might help. I want to say there are certain cleaners that are great for cleaning up any water spots that might be shorting things out, but I've never had to try myself.
That's all I can think of right off. Good luck.

Yeah, I'm working on taking it apart right now. With my limited experience on electronics, I would be willing to bet it's a capacitor that's gone bad somewhere. That wouldn't be a problem on a desktop since I could just solder a new one in, but I don't think I have the skill to do something in such a small scale, not to mention I don't think you can even buy them that small.
The same thing happened to me, and I had to send it in for repair. Luckily, I was still in warranty. Also, are you sure it's not the charger cord?

I've tried multiple cables, and I'm unfortunately out of warranty.
Upon disassembling and cleaning with rubbing alcohol, it seemed to be working properly, with the exception of computer connection. However, I plugged it into a DC car charger (leaving the charger itself unplugged from an outlet), and the light came on again (which is what I was talking about when I said it was sending power out), and now it is acting weird again. I guess I'll take it apart and clean it again...

See! Told you taking it apart and putting it back together again works... temporarily. :silly:
You're right, that does sound like power going out. Which would be super cool for powering, say, a micro USB laser pointer, but it's not so great when it should be charging. Can you double check with another device that the charger doesn't light up normally? I know my wife's laptop charger has a LED that stays on for a long time after it's been unplugged from the wall, sipping off of power left in the charger. It could be something similar with your charger.
Just a though... if power is only suppose to go into the device, then wouldn't it be reasonable to assume to that there would be a diode forcing power to only go one way? Or does it need to cycle power back to the charger? IDK, but it might be worth looking to see if something looks missing.
I read somewhere that if the battery voltage gets too low i.e. battery is totally flat, a current will flow from the device to the charger so this may be what's going on here. I didn't really understand the post as I was just whizzing through the thread, but i think the solution was to charge the device for many hours until the battery voltage was high enough for normal charging to occur. I'll try and locate the post, but it might take a while

@iJimaniac if all of these suggestions dont work, there is the possibility to just buy another battery and a battery charger and keep switching out the batteries when they die
Maybe @henk5066 would know something about this?
From what it sounds like, your power circuit is fried and is not directing power correctly this means that you're probably going to have to replace the mainboard. however don't worry. you can get one from a player with a broken screen on ebay for about 10 $. I can p.m. you some links to products on eBay with main board working and not screen and I can post a video on YouTube that shows you how to replace the board. it's actually rather quite easy. I don't get why most people don't do that and instead buy a new one. let me know if that helps

Wow, I didn't realize a broken player is so cheap. I'll look into it, and instructions won't be needed; I've already fully dissasembled my device many times in the past, just for kicks.
Edit: could you send me those links? I'm having a hard time finding very many under $25, which is still a good price I suppose.
the broken player it's self is cheap (0.99$ if your lowest bidder and win) it is shipping that makes up for most of the cost. Just make sure you get one that says powers on, that is the main indicator that the main board is still good.
EDIT: I just looked on ebay, aparantly the person i bought my new board is out of the 4.0 player. and it looks like there is however one with a 9.99$ bid. you could raise it and get the player but that is the cheapest you will get. i will pm you a link to it.
I had the same problem
I had the same problem, what i did was, instead of charging it with the original charger, i charged it with my nexus 10 charger in download mode all through the night, and the next day it would have about 80 percent charge and it was in the system, but it drained quick when i would unplugged it, so i repeat the same procedure over several days until get to 100% and scince then i have had no problems with my SGP, hopefully i helped you

Interesting, i thought the devices could not charge in download mode.
On the subject of odd charging behavieor, has anyone noticed that when plugged in running cyanogenmod overclocked to 1200mhz, the micro usb port area on the player gets rather hot?

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 have noticed that fast Charging does not always happen even with the stock charger. However, if I reboot then fast charging kicks in. Is this a known issue?
No, I always have fast charging. Maybe you need to return your tab for warranty.

I have this problem as a result of getting something in the charging port, or inside the USBC cable itself. All resulting in a moisture detected error. Powering down the tablet, plugging it in and allowing the charge indicator to come on would resolve the issue, but every time I unplug the tablet I would get the error again. I followed instructions on XDA regarding USB C fast charging problems and it seemed to fix the error. I think there's still something in the cable itself because the whole problem has expressed twice now. But in the interim comma over a few days if I plug the charger in one way I would get a slow charge warning that I wasn't using the original charger. But it's the charger that came in the Box. If I unplugged it, turned the charger around and plugged it in the other way it would fast charge again. So I'm guessing there's some kind of material in the charger itself that I can't get to that's affecting how many contacts are being made. I'm still working to resolve the issue with the original charger, but I'm thinking about just getting another USB C cable. I need a longer one than ships with the tablet in the first place.
When I went to chat with customer service, they wanted me to send it in under warranty. But I really didn't want to do without the tablet for 2 weeks or more, so researching it online has solved the issue somewhat. I might take it in to a Samsung kiosk and just see if they'll try to fix it with air duster.
