[Q] Dock not charging but working fine when docked - Asus Transformer TF700

My TF201/TF700 dock does not charge at all, it shows 0% when docked. The keyboard and touchpad works fine when docked. The orange colour LED blinks when docked but when undocked no light indication when charger is connected. The same charger works fine as it is charging my tablet. I can even access the tablet with fast boot through the dock so the connections are fine but it will just not charge. My doubt is with the dock firmware (DOCK-EC20N-0207). My TF700 is unlocked and running CROMi-X 5.3 - 10.6.1.27.5 ww DEODEX. Any sugestions

Sounds like a battery or charging unit fault.

Yes, looks like the battery is dead. Have you left it at 0% without charging for an extended time? Li-ion batteries don't like that at all - once discharged below a certain level they can become unstable, so maybe the battery safety circuit prevents recharging.

Best way to troubleshoot if you have no equipment to test the battery separately is to open up the tab (if you're game) and plug the dock battery into it to charge. I've done it myself. I'd bet it's not so much the battery is dead as it is the dock's charging circuit is screwed up. In my case, I've tentatively diagnosed that the I/O controller (Nuvoton NPCE781LA0DX) on the bottom side of the dock board has died. Seems to happen to a lot of 201 docks. Sub-standard batch I guess. Still waiting for the chip to arrive. I'll be sure to report on any progress.
@sdbags: you mentioned the charging circuit. Do you have any more info on this hardware-wise? Like a schematics for instance?

No mate just a guess thathat it was the circuit or the battery.

I have opened the dock and checked inside and everything seems fine, I also suspect that the charging circuit is the culprit. Any idea where to get the whole board from???

You can't tell really just from the look of it, unless something burned so badly as to leave traces. Ebay sometimes has the board used, but they typically want somewhere around $40 USD, which is almost the price of getting the whole dock sometimes. That's why I decided to mess with the components, out of curiosity more than anything else. If it doesn't work, I can always buy the board.
If you can hang on for another week or so, I'll let you know how it goes in my case. Even with the I/O controller damaged, everything else works fine with my dock.
In your case, it's always possible the battery is gone. You'd need to check that out first before considering anything else at all.

You are absolutely right, I will wait to how ur experiment turns out. In the mean while I will try to check the battery out. As my dock is functioning fine except for charging itself and tablet I am ok with it till I find a clear solution to the problem.

The chip is the right one as quoted before. Or you can read it off the board. There are 2 different versions for the dock, but if I remember correctly, they both use the same chip. You can buy it on Ebay for around 5 bucks (US). You can remove it with a nozzled heat gun to limit the heat to one area and use Kapton tape or heat dissipating shield to cover the surrounding components. The hard part is to solder the thing back. Without appropriate iron and lots of flux, you won't succeed, I'm afraid.

Dock won't charge but still charges tablet and functions well.

I've seen many questions about the dock but can't find one that talks about this issue I just had this morning.
Last night both my tablet and dock were charged completely. This afternoon I start using my tablet and notice the tablet is at 30% and the dock is fully discharged at 0%. I plugged the keyboard in connected to the tablet to charge it. The tablet is charging just fine but the keyboard is flashing the orange light and is not charging. I have tried plugging just the keyboard in and it is still flashing orange and not charging. I thought it could be the power supply but the tablet itself is charging just fine.
Does anyone have any ideas I should try before trying to see if I can get a replacement?

When the dock is fully discharged the red led will flash for a while when your charging. It's normal, when you have charged for a while it will be constantly on!

Defective. Exchange dock or send to Asus for repair.
I don't know what happened but I left it plugged in all night yesterday and this morning it was half charged with the light on orange so I'm hoping that sometime when I was sleeping it fixed itself.

I've had a dock die and just flash with no charging on the prime before guess it was defective. Picked up an open box from ebay for 90 bucks works like a charm.
I got the dock to charge, but had to monkey around to get it to fit just right....still not fun....
Got it solved by doing a cold boot.
Turned it off then held power + vol down combo untill I saw the text "cold-coot linux" apear, released the buttons and waited boot.
Now the charging light is blinking.on the dock.
Ok. Honest mistake. It wasn't charging. It blinks when active (connected to tablet and tablet unlocked...if you lock the tablet the dock led stops blinking).
Tried the cold boot thing described above. Didn't work.
The charger charges the tablet alright, but not the dock.
Opened it up yo see if there was something wrong (cable disconnected or so). Unplugged and plugged everything back. Still won't charge. =/
Any ideas????
Thanks in advance!
Got it to charge using a pliers. Images attached.
Apparently or my dock jack is bad or my cable connector...most probably the dock. =/
Any ideas on what to do now? Where can I get this jack? Is it not extremely hard to replace? Worth it?
I'm in Brazil, so I got no official ASUS support for this piece. =(

I have the same issue, and after reading your post, I tried your hack and the charging light finally came on for my dock. Evidence strongly suggests its a flaky electrical connection in either the cord or the jack. I am leaning towards jack because my cord will charge my tablet when directly plugged in, but I am not yet convinced.
Noticing that the connector's pins are on the outside, and it connects to a double-sided blade of pins, I tried to squeeze the connector some to make a better electrical connection. It was a little better, in that I could occasionally now get the charging light to turn on for a few seconds by applying pressure to just the cord's connector, but still not reliable. I then tried to use a small blade between the plastic and outer metal casing of the cord's connector, and I destroyed the came and now it won't even charge my tablet. I'll have to go to the store tomorrow to replace the cable, and we'll see if a new cord works to power the dock.
There's a distinct possibility that a new cable might just be all the fix I need.
Looking at the teardown on ifixit, it seems like the tablet uses a slightly different connector housing than the dock. Perhaps the dock has a less reliable part.

A new cable did not fix it.
Without another good path forward, I get brave and have attempted to reshape the receiver jack's metal housing to be more snug, hoping that a squeeze would do it. I have only managed to mangle it further.

[Q] dock not charging: tf700t with tf201 dock

Hi all,
I've searched the forums thoroughly and I couldn't find the solution.
I have a brand new transformer tf700 and keyboard dock tf201. They were purchased in the USA and brought over to me in Hanoi, Vietnam.
The charger will charge the tablet, but not the dock.
When the charger is plugged into the dock, there is no light. Also nothing happens when connecting the tablet and dock. No light on either, and the tablet does not enter a docked mode. So it seems like the battery on the dock is completely drained or the dock is simply faulty.
I've tried leaving it overnight for the initial charge (first thing I did), as well as different outlets and charging by USB.
Since the charger works on the tablet it seems obvious that the problem is with the dock, but is there any further troubleshooting I can do to confirm this 100%? Since I'm in Vietnam, sending the dock back for warranty etc.. is going to be very problematic and in fact its illegal for used electronic items to be shipped back into Vietnam. So I really want to know 100% for sure what the issue is. Vietnam is 220V / 50HZ and it seems the charger is rated for that.
I'm open to more advanced options such as using a multimeter.
Thanks.

It could be that the charger was meant for a newer version of the dock. Your using a TF700T charger with a TF201T dock.
It could just be a compatibility issue. If so just buy a TF700T dock or buy a TF201T charger. I hope this helps.

Very unlikely. I regularly charge my TF700 with the TF101 charger, and I am almost sure the TF201 uses the same charger.

Perhaps, the docks power supply died. Which would mean either buy a new dock or send it in for warranty.

Well I need to test this 100% for certain, because I can't send it in for warranty due to Vietnam's import laws, and the dock is not available for sale here at the moment. So neither of those options are viable
Like I said it has never worked but so far the only advice I have gotten essentially is "plug it in" as well as check the charger. The charger works fine with the tablet so I'm pretty sure that its not that, however I am curious about the mechanism by which it jumps from 5v to 15v and how it may behave in houses with or without voltage stabilizers.
Unless I've overlooked a very simple step I'm really wanting to move forward into a more technical analysis (ie: checking voltages / opening the dock).
Further info: the shop tested the dock before sending it (it was open but unused) and it worked fine.
So this strengthens the case for a charger/voltage/amperage related issue. Of course it could have been damaged in transit but it was DHL priority and appropriately marked so not too likely

It could just be you need a universal plugin to convert the amperage.

Well a universal plug as I know it is just an adapter. It doesn't have any step-up/step-down capabilities.
But if you mean a universal power converter then possibly, although usually they just provide 12v, not 15.
The supplied adapter should be fine though, because its rated at 110-240V (Vietnam is 220V) and 50/60Hz (Vietnam is 50Hz).
My only thought with the adapter was whether it was having problems stepping up to 15v as it charges the tablet at 5v just fine.
Question: Does trickle feeding the tf201 on USB work? Also does the light turn on for a trickle feed?

does this do anything.....
fully charge the tablet on its own, connect it to the dock, connect the charger (plugged in), restart the unit?

No I tried that before creating the thread. Thanks anyway.
Don't know if this has been asked yet, but does the dock actually work (not just the battery)? Can you plug it into a nearby computer and access the mounted tablet? Also, there's a widget on the tablet that can show if the dock/tablet is charging or not. Also, you mentioned trying power from different outlets. Did you try outlets in a different building (like a hotel or university)? I've seen from visiting Brazil that "standardized electricity" doesn't mean that everyone has adopted it.
From what you've mentioned, you really have 3 viable options of failure: Dock battery is bad, dock is completely bad, or incorrect power. If its the battery, then you get to decide if you want to rip it apart or not. If its completely bad, then you would probably need to send it back. Finally, if it just doesn't work where you are, it could be that the building isn't up to standards or even that there might be electrical issues in the building your at.

It seems like there is a trickle and the light does not turn on. I only tried it for about a minute but the tablet did show that charging was happening. Maybe later I'll try a longer test.

Not yet, but I will try that soon. I have a working voltage stabilizer in my house, as well as about 8 computers and 5 tvs etc.. Everything works very well and when I fixed some people's hardware recently it worked in my house but not theirs (due to my power supply being good) so I'm pretty sure that's not the issue. I will take it somewhere else though just to rule that option out.

Right, that's the conclusion I came to as well before posting. So I really wanted to know if I had overlooked something simple (doesn't seem as though I have) or begin more advanced diagnostics such as using a multimeter or hear some stories from someone who has taken their dock apart before I tear in.
Thanks again!
Well, I believe that the tablet should find the dock even if the dock has no battery power. The battery of the dock is merely a backup battery for the tablet and not used by the dock itself for functionality. For this reason, I think you got just a bad dock. If you want to try to replace the battery (since you are closer to China and Japan), you are looking for a C21-TF201D battery. You will need a small torx screwdriver (like a T-3 or T2 - my smallest is a T-4 which is just barely too big) to remove the screws in the back and a Phillips 0 to remove the screws under the pads. Top piece can then be lifted gently and there are 2 ribbons underneath to fully detach the keyboard. From there you should have just a few more things to do to get to the battery. There's a teardown video here but the speech is almost inaudible and the music is distracting.
What I was thinking is that the dock was tested before shipment then it arrived nonfunctional. It leads me to believe that something was damaged during transport (derrr, yeah I know that's obvious just bare with me). If that something damaged was the battery, then there could be some leakage that has led to possibly corrosive damage to other electronics in the device. And that wouldn't be fun to try to fix on your own. If you want to continue trying to troubleshoot it, you might want to do it without attaching the dock to the tablet until you find out what is wrong because you don't want to possibly fry your tablet connector due to the dock acting unreliably.
You should probably start talking with your shipping carrier about the fact that the device was damaged and that you should be reimbursed somehow. This might allow you to get a new one through them or sufficient money for a replacement.

What can I say, you're a legend. That's just the kind of info I was looking for. I'll get stuck into it soon and let you know how it goes.
I also wondered about whether the tablet should connect to the PC via the dock but my thinking is that you may need a minimum charge to get through the extra circuity in the dock (all dem capacimataters and circamatronics). But yeah I see your point.
About the dock working before they sent it, I'd take that with a grain of salt.
Full disclosure: When the company sent the package, they forgot to include the dock altogether and my friend left America the next day. When I was talking to (screaming at) them, they said they were totally out of stock except for one which was opened but unused. They agreed to courier it (DHL express international... ouch) over to Vietnam (as it had most of its packaging so could be treated as new. ). Why that dock was already opened in their shop I wonder. Methinks it was probably already broken and they are trying to cut their losses (they already had to cover international shipping and 100% import tax so they lost out big time due to forgetting to send the dock. They knew I couldn't send it back from Vn either).
Once again thanks!
I've swapped in a mainboard from another dock that had a bad battery.
Now the dock dock functions fine, and the tablet connects and can be charged through the dock.
However the battery light for the dock just stays as orange no matter how long I charge it for. And it always shows 0% battery on the dock so it seems like the battery doesn't charge at all.
What areas should I check? Also if I use a multimeter to check the battery, is there any way to tell if the battery can hold charge (and the issue is somewhere in the connectors) or if the battery cannot hold charge at all?
I tried a cold boot, no luck. Perhaps an alternative is the mainboard needs some kind of hard reset to recognize the new battery? Or of course the battery could just be bad, like the mainboard.

Unfortunately, it has been years since I've used a multimeter for these situations so I wouldn't be able to help you out directly in that area. Googling for how to test batteries on other devices - like the TF101 dock or even regular batteries - could provide additional valuable information to help you in your experiments.
There's the possibility that it's merely a calibration issue where the dock has no knowledge of the battery's charge, but the fact that there's a constant 0% and the light stays orange all the time (never turning to green) then it leads me to believe it's a bad battery. Have you tried checking if the tablet continues to charge from the dock with no charger attached? If the dock charges the tablet in this fashion, then it's a battery data issue. Likewise, have you tried to use the dock without the battery, detach dock, then reinsert battery to see if that spurs the dock to reset its battery data? You might also look into an app or widget that will show you the battery output charge and all (like this). That's all I can really think of at the moment. Hopefully, from whatever tests you perform we can discover whether it's really a bad battery or something else.
Thanks for suggestions Alienedd. I ended up going back to Australia for Christmas so I quietly slipped the defective parts back in and made a warranty return.

Battery suddenly dead on both dock and tablet

Until yesterday, my TF700 was working perfectly fine, but now I'm concerned as the battery in both the dock and the tablet have stopped working.
The AC adaptor's connected to the dock and I always charged both the tablet and the dock together for the most part.
I went to check the device this morning and suddenly found that they're not working at all.
Yesterday evening, I tried switching on the tablet and it would switch on and reach the ASUS screen, but not fully boot up.
I bought it from Amazon's Amazon Warehouse division and I have until the 31st to return this, but in the meantime, I'd like to know why the batteries have died on me suddenly and is there anything I can do about it.

I bought it from Amazon's Amazon Warehouse division and I have until the 31st to return this, but in the meantime, I'd like to know why the batteries have died on me suddenly and is there anything I can do about it.

If it's a genuine hardware failure, you'd have to return -- unless you're very proficient at handling and replacing sensitive electronics yourself (microwelding, for example).
It has been reported before, and could be fixe din almost every case by letting the 700 be dead for at least an hour, and then let it fully charge while off (!) -- just let it sit hoked up to the wall charger for at least 8 hours. Then try to turn it on again.
Good luck.

I'll give that advice of yours a try especially as I don't want to have to return it if it's something that can be easily sorted out.

It never hurts trying -- you aren't exactly the first to describe this, but luckily, pretty much all of the others were saved.
I finally managed to get the problem sorted out as it seems that the connection to the port on the keyboard had somehow come a bit loose without me noticing it.
Unfortunately, I have a new problem in that the cable itself seems to have died in that it won't work any more with the adapter as it started crackling a bit when I knocked the connector attached to the AC adaptor itself gently by accident. :crying:

Well, I hope I am right in assuming this is not your luckiest week, huh? Is the cable damaged near the wall charging part? (That's what I understand.) The replacement cables probably are not that expensive, so I'd plonk down on a new one instead of initiating "daredevil repair mode".
Saying that gives me that MacGyver feeling. Duct tape and a pair of scissors would be all that he needs to fix this.
Oh, and maybe a pair of toothpicks and an old sock, just for looks.

The cable itself is fine (it's not worn down to the wire literally like a lot of cables and AC adapters you get for devices like iPods and Galaxy S II's), it's just that it has this weird burnt-like smell at the end connector that plus into the USB socket on the AC adaptor.
As for replacement cables, I'm surprised that they're not that easy to buy offline.

Agreed -- buying them offline is a definite hassle. I have seen them online, though, and you can even hunt down the charger parts or the TF101 and TF201 Prime. They will work flawlessly.
BTW and FWIW (gotta love acronyms), my charging cable smells a bit funny at the end too. This specific one has to put through a lot of power, so I'm not even that surprised.

In all seriousness though, I love my TF700, it's just a shame that it's such a pain in the ass (not literally!) to buy official accessories in the shops and it's not as if you can buy a USB cable for it in the shops unlike ones for the iPod, iPad and iPhone.

No, it's a definite PITA
-- I had hoped that the new EU rulings concerning all smartphones needing to provide a microUSB charging input would extend to tablts, but so far this has not been the case, unfortunately.

Just giving you guys a update concerning my device: It seems now that both batteries don't want to work any more for some reason or other as of yesterday. I've checked both the official USB cable and a third-party cable plugged into the official USB plug and they're not charging up the device at all.
The tablet can connect to my laptop as a media device without any problems, but I'm confused as to why it's not working at all when plugged into a USB adapter.
In any case, I'm going to order a AC adapter from eBay later today and see if that works or not.

[Q] Need Replacement Charging Port

The tablet needs a new charging/interface port and was wondering if anyone knows where I can get one?
I have searched Ebay and the net for a used/new one. The port looks fine but when plugging the cable in it won't charge. Sometimes I can get it to if I push and hold it just right however this is tricky to do and does not work often. So right now it is a dead brick. The pins must not be making full contact for some reason.
Ive bought parts from these guys before, I don't see a charging port but might be worth giving them an email and asking

Thanks but I would rather not have to order parts from Sweden. If I have to I'll just keep watching Ebay. Every so often one pops up but doesn't last very long.
Good luck
The parts I ordered took about 4-6 weeks to arrive iirc
Just installed a new (used off Ebay) charging port with fingers crossed that it will allow the tablet to charge. I also have a new high quality charging cord (PWR+) and two ASUS wall chargers that I know work. Plugged the tablet in and was relieved to see the tablet come right on and show it charging. Let it charge to about 20% and then decided to unplug it so I could put the ring back on the tablet so it is all back together. Get the ring on and plug the tablet back in and nothing. I'm about to throw this thing in the trash right now. So fed up with these charging issues. What changed? All I did was unplug it, put the ring on, and plug back in.
So for kicks I decide to try the other wall charger and what do you know....it came on immediately and started charging and is still charging. I'm afraid to touch the thing now. Seems once it is charging and undisturbed it will charge to 100% no problem. However, when going to recharge it won't charge. Could there be something in the charging mechanism causing the thermal to trip in the wall chargers? Is there possibly a small short somewhere in the charging mechanism? Anyone have an opinion on why this is happening? Only other thing I can think of is doing a full wipe/reset and maybe flashing another rom (is currently on newest Android Revolution HD) once it is charged up.
Could the ring (I assume you mean Bezel ? ) or the screws near the port be shorting the charging port to earth/ground/chassis ?

Yep.. Sry.. The bezel. Not sure how but anything is possible. Would indicate to me a faulty charging port or charger cord and is happening on multiple. Tablet is still allowing me to charge it at this time after switching chargers and with the bezel on so will have to see how it goes.
Sent from my tricked out S4.
Fingers crossed it was a coincidence with the first charger, if not, I'd try taking the bezel off again and see if you can spot the short / see if it works again with the bezel off, or even just with the screws out

TF700 not charging

I mean, after almost a year of having this thing, this is the first time I've experienced something like this. I thought that my surge protector might have had something to do with it, but no matter where I plug it the dock/tablet combo won't charge. I even tried charging the tablet by itself but that didn't work either and I also thought that it might have been the cable, but my PC still detects the tablet.
I'm running an older version of cleanROM from around the month of May if it helps in some way. I would turn the tablet on to check, but I want to preserve the remaining 5% in order to fix this problem.

Seems like a defective cable or tablet. If the tablet doesn't even charge from the dock, it looks more like a defective tablet. If the dock doesn't charge without tablet, it may also be the cable or the charger.
Try this: Keep the tablet off and connect it to the PC (without dock) for a couple of hours - that should charge the battery very slowly (a few % per hour).

I have had similar problems with my TF 300. After researching more of this I find that most of Asus tablets have similar problems. One is the charging cube tripping an internal breaker and allowing only 5v to come out and trickle charge the unit. Some have placed in freezer or just allowed to cool and they seem to work. Others have just had a no charge problem. The battery symbol comes on when you attach the charge cable then disappears but does not show a charge. Some actually turns on a tablet that was off after attaching the cable but still no visible charge. Some will still charge, they just take longer to charge. It seems Asus knows this and it can happen from a few months old to 1-2 yrs old. Now I'm not sure about most people but to pay $400+- for a tablet and get only about 2 yrs usage is not acceptable. I can understand technology passing a tablet or laptop by, that's technology, but for a product to only have a 2 yr life expectancy is not really allowable and should be addressed by Asus. Hook it up if this is not to old of a thread and try it. It may charge even though it doesn't show. If someone else is reading this with a similar problem then try what I have written. It may still charge even though it says it's not. Write Asus and complain. It seems Asus is a very expensive product to fix also. Galaxy Tabs seem to be a very inexpensive product to fix so they may be a better choice for a very similar tablet. :fingers-crossed:
TF700T not charging
I read in one of the threads to put the charger in the freezer for a few minutes and it worked. Thank you.

Yes, same thing, only I thought the charger wasn't working, ordered a new one (still waiting), left it off the charger for about 30 hours but on the PC, then connected the charger up again and now it's charging!
