[Q] Dock will not charge

My TF pad charges just fine, so there is not any problem with the charger. However, the dock does not charge at all. Even after 12 hours plugged into the wall with the unit turned off, the orange light is still flashing when I boot up. This might be a problem with the firmware. I am running:
HRI66.US_epad-8.2.3.13-20110511
I read somewhere that I should reflash the firmware. I have downloaded this version of the firmware onto a USB drive and the TF recognizes it but will not open the zip file.
What are the steps required to reinstall this firmware? Does anyone know of any other ways to fix the charging problem? The ASUS support site is nearly worthless. I humbly apologize in advance for my ignorance and thank anyone who responds.

that is the Build Number, and mine is the same and I updated everything correctly so it looks like you have the most updated version.
My MobileDock version is EP101-0209
It might be an issue with the dock charger, a hardware issue, the battery may have stopped working, we never know...
if it's a firmware issue, give Asus CS a call and ask them what to do next or how to properly install it.

Does anyone have any other suggestions? My keyboard has stopped charging as well.

Same for me unfortunately
Sent from my Transformer TF101 using XDA Premium App

I had the same issue and had to unplug and wait, switched outlets and it's fine now.
There is definetely something wrong.

Maybe it's designed to fully charge the tablet first then start topping off the dock.

I had the same issue - constant flashing orange led no matter what configuration I tried.. TF docked, TF not docked, TF docked powered on, TF docked power off, change outlets, let it sit for hours and hours (over 24 at one point) etc etc
Nothing worked.
And like yours, my TF always charged - whether docked or not.
Called Asus - w/o even asking any questions they just directed me to the RMA dept.
Instead I just returned it to Amazon and then waited until I could order another one. It took nearly a week, but they finally came back in stock on Amazon (for an hour) and I ordered another.
It should be here Wednesday, so by then I'll know FOR SURE whether it was the first dock that was bad - or if it's my charger / cable.
I'll post back once the new one gets here..

My keyboard is waiting for UPS pickup for a Newegg RMA. The keyboard is deactivated at Newegg now. I'm wondering if they will wait for more stock or give me a refund. I'm just glad I still have the tablet.
Does anyone know how widespread the dock charging problem is, and if newer units have any changes to fix this?

The docks were scarce here in Taiwan, still are. That must be an indication something is rotten in Denmark and Asus knows and are working on it.

Updating from my earlier post: My new keyboard / dock arrived yesterday. When I plugged it in, the LED was solid orange (ironically, this LED looks a lot more "red" whereas on my other dock it was definitely "orange").
I charged it for 8 hours and the LED turned green during the charging time.
So at this point I can definitely say that it was the dock that went bad and would not charge - as opposed to the charger being bad.
I would advise just returning your dock to the place of purchase if it's no longer charging.

Be interesting to see if those having charging problems with the dock have an orange or red led. I have had no issues, but my led definitely looks red. When the charger is charging, it gets very warm (hot). If your dock has been plugged into the charger for more than 20 mins and the charger is not very warm, it probably isn't charging.

Just wanted to update my previous post (2 up) because now my second dock is dead.
Under normal usage everything would worked fine - the battery would drain and then charge - no problems at all.
HOWEVER - There appears to be BIG problem with these docks and I feel this is what is causing (or contributing to) my docks dying. These things have a constant drain on them when the Transformer tablet is attached - even if you power the tablet OFF.

I believe what is happening in my case is that the dock battery drains to a point where it will no longer accept a charge. In both cases, I had the tablet docked to the keyboard - powered OFF - and did not use it for a week or so. When I went to power it on, the tablet/dock had just enough juice to tell me that the battery was very low (I believe around 1%) and that it needed to be charged - and then it shut down.
OK, fine, no problem. I plugged it in to charge and left it.
The tablet charged up to 100% with no issues, however 72 hours later and again I have a keyboard dock with a constant blinking orange LED that will not charge. Again, I tried charging it with the tablet attached and without - no change. The adapter doesn't even heat up when trying to charge which again tells me that something in the battery on the dock is not accepting the charge.
Looks like this one will be going back to Amazon as well. I'll also contact Asus regarding the issue and will report back what I hear.

Hello,
I Have the same behaviour,everything were fine until I unplug the dock during several days and the charge was down at 0%.
Now, I 'm unable to charge the dock with or without the tablet plugged
I hope that it's only a firmware issue.....................

Sorry to hear it, but thanks for letting us know.
I have a bad feeling that this is an issue that is going to end up biting MANY users after their return period has expired. It seems that the huge majority of TF owners use their tablets / docks nearly every day - if not daily - so they won't run into this problem.
I'm concerned that after a month or so and some of the excitement has worn off, and they put their TF/dock away for several days suddenly their dock will be rendered useless (at least as far as the extra battery goes).
I've just sent a note off to Asus (per their request from my Amazon review) and I'll let you know what I hear back.

OK
thanks you for your action !! and to keep us informed.
For me, a lot of people are concerned ..... as you said...

i have same question too

My dock has same problem, have tried with or without tablet recharging, the led of dock is always blinking red when tablet connected, and dual battery widiget always display it's discharging and slow draining from 40% to 35% now.

In order to consolidate and try to keep this issue in one thread, I'll only be updating this thread going forward: http://forum.xda-developers.com/showthread.php?t=1112835
I just added my latest correspondence with Asus on the matter, but unfortunately it doesn't look like I'm really getting through to anyone of quality over there..

gents,
just wanted to add my possible fix for this issue.
I had this probem and my dock would not charge. Somehow i got it working again. Here are the steps i took, not sure what fixed it in the end but you could try and replicate and see how you get on.
1. I went to charge my keyboard on its own. I left it charging for hours and it was still flashing red.
2. docked the keyboard and the power widgets showed no juice within the dock althought it worked as a keyboard.
3. I plugged the power in the dock while docked and on. It showed that it was charging the tablet but not the dock. The dock stayed at 0%.
4. I left the two charging while on for a few hours. The tablet was now showing as charged but nothing still in the dock. I then shut down the device with a turn off but left the power and the dock in. As i shut down the light on the side went to solid red and stayed solid red while the device was off.
5. I left the device off but with the charger in the docked keyboard for about 10 minutes. I then turned the device on while docked and still charging. When the device turned on the battery widgets showed the dock with 35% charge. i left the device alone for a while on and dokced and charging and after about 10 minutes the dock charge started going up. I left the dock charge while the on the tablet was on and docked until the dock was charged to 100%. I then turned the tablet off. took the charger out and undocked. Turned the tablet on while on its own. Then docked it with the dock with no charger in and da daaar the keyboard showed 100% charge and was working......yea!

This is what I figured out, not sure if it's actually true but whenever I did some huge data transfer from the datacable computer --> tablet afterwards it wouldn't charge... so I had to leave it unplugged for over 6 hours adapater and cable, then tried again and it works... still going to go visit the local asus warranty center sigh.

[Q] TF battery no longer charging. Any suggestions?

It looks like the battery on my TF is refusing to charge. Started all of a sudden last night. I tried to turn it on and it didn't come on even though I didn't use it much,so I figured the battery may have drained somehow. I plugged the charger and sure enough I was able to boot the transformer but the battery is not charging and it displays an exclamation mark on the battery icon. It is showing 0% charge for over a day now even though I had it plugged in all this time. I tried turning it off and keeping it on but it doesn't make any difference and it doesn't charge. I tried full factory reset but it didn't help. The exclamation point stays on the battery icon and it is not charging. It works when plugged in but shut off as soon as I unplug. I don't think it is the charger because the same charger charges the dock just fine. So I am afraid that it must be the tablet issue. Any suggestions before I start the RMA process? Thanks.

That's weird. Mine started doing the same thing in the last day as well. Won't charge either when plugged in via the dock or the tablet.
Anyone got any ideas?
Edit to add: Ah, got it working. Seems that unplugging the adaptor and waiting half an hour seems to reset some trip or other. Odd, because it doesn't seem too hot when I leave it plugged in.

Good for you... unfortunately this trick doesn't work for mine. Had it unplugged fo hours, plugged it back in and same thing. The dock charges fine so I don't think it is an adapter. The TF is not charging if plugged in or docked on the kb. Tried to take off adapter prongs and re-seat it and still same problem. Adapter doesn't seem hot at all.

I had a question mark as well. I ended up sending it in. It did happen right after the battery was very low and I tried to turn it on, while the adapter for some reason was not connecting (it happens every now and then that mine does not connect). So I think it had something to do with that - battery got too low.
In addition the tablet was no longer recognizing the dock - it would just show the question mark and the dock did not work.
Anyway, I sent mine in, and requested they address the battery drain issue (which at that point was just announced in the Asus Facebook UK page). Came back fixed ... first the tablet - and they found no problem with it, then the dock about a week or little more later - cambe back working with no battery drain issue.

Thanks for the response, not sure if you had a typo or if you had something different. I actually have an exclamation point (!) not a question mark on mine. Just called ASUS support to get an RMA. Was on hold for close to 40 minutes until someone finally picked up. The guy was like a robot, but I guess it was expected. Told him about charging issue with TF and about my dock not switching to battery saving mode (I have one of the first models) and he said to send both in for repairs. I asked if I should use the original packaging he said I was responsible for packaging. I said I understand that and if I use the original boxes from TF and dock, will I get them back? He said no... I guess I will just have to wrap them well and use other boxes. I am wondering how others sent them and if you got your original boxes back. I mean it has serial number and other numbers on it that I may need.

TF700 only charging to 90 from AC...

Hello all,
Just upgraded from the Asus Transformer Prime to the Infinity and I am loving it but I am having one problem, the unit will not charge past 90 when being charged from the AC. The unit will charge while in the dock to 100 but not from the AC alone. When I detach the tablet from the dock, it still shows that the dock is connected but that the battery level is 0% with the red exclamation point. After I remove the dock I cannot use the software keyboard until after a reset. First thing I thought to do was factory reset, since I thought that would also be good after the firmware update. Didn't work. Then I tried a cold reset and also deleted the battery stats. What am I missing here? I do I need to RMA, is this a charger issue or is there an easy fix I overlooked? I have checked everywhere for a fix and found nothing. The closest I have found was to attach the Infinity to the computers usb port then switch to the AC but I have had no luck with that either. Any ideas?

Tried a factory reset?

Have you tried battery calibration? This application was recommended by other thread and requires rooting, but it may be worth a shot in your situation. The other option before rooting for this app is just simply do cold boot if you have not done so.

It's a myth. There's no such thing as battery calibration. Look for a post (Google+ I believe) by a Google engineer.

I am rooted and have calibrated battery , did nothing. I am sending this one back. It will not charge to 100 from AC with power on. Even tried freezing the AC that i got from another forum. This sucks cause otherwise this unit is solid. I feel like somehow my TF201 dock messed this one up.

Did you try discharging it until it auto shuts down then charge to 100%I would also leave it alone until fully charge. Then use Battery Calibration to reset data and calibrate.

Mine just stopped charging past 57% yesterday. Rebooting hasn't helped. Came to the forums to see if others were seeing it too. This is the closest report I've seen. Guess I'll try a cold boot.

I have tried this but the problem is that my hardware is only accepting a full charge from the dock. I will run it down again today and try to charge it powered off to 100. What I need is some code to change in the build.prop that controls what the tablet does when the dock is connected and disconnected. It is in a state where it depends on a dock to function and charges using the AC like it was the dock. Probably hang on to this Infinity ity till the weekend since I see another person is having this problem and maybe we can figure something out if we work together.

Tablet Won't charge

I just got my tablet returned to me from Asus after the screen cracked. I got them to fix it no problem. I was also trying to get some repairs done on the keyboard dock but that shut off my tablet and sometimes smoke up. I decided then to return the keyboard to best buy and they let me exchange it for another one. The new keyboard worked fine and I was thinking all my previous problems were related to it. A few days ago I woke up and noticed my tablet and new keyboard were not charged all the way. I did not think much of it. That night I tried to charge both of them but neither device would charge. I figured it was the USB cord as one of the black edges fell off and it looked pretty warn. It would still charge, it was just the tablet said it was not charging and it seemed slower. I bought another USB cord from Amazon and tried to charge the tablet with that cord. At this point my tablet is actually dead. I am trying to charge it now but it still will not start up. Do you guys have any suggestions on how I may be able to fix it. I really enjoy using Android on my tablet but Asus hardware keeps falling apart on me.
Edit: I did manage to get it to start after I unplugged it. After it started, it told me the battery is at 0% and shut off. I am now trying the old cord now.
Edit2: The old one got it to 1% but again the charging is much slower then it use to be

Keyboard causing tablet to shutdown?

Is anyone having issues with the keyboard causing the tablet to turn off? It's not doing it while I'm using it just when I close it the tablet turns completely off sometimes. I've had the tablet for several weeks and had no issues but just got the keyboard a few days ago and now it has random shutdowns. Example: On break at work I closed my tablet and walked approximately 50ft to my workstation opened it back up to plug in the speakers to listen to Pandora and the tablet was off, not like stuck in sleep mode but completely off had to hold power for 1-2 secs it vibrated and thee boot logo came up. Would like to know if I should contact Asus or if it might just be a bug in the ROM.
Asus Transformer Infinity Champagne 32GB CleanRom 3.1 Odex

Happens to me sometimes, too.

Happens all the time here.
There is a thread about it.
No solution so far.
I have returned my tablet 3 times to my reseller (it's currently in their hands), who RMAed it to Asus once. I have no info about what they've done.
After the last RMA, it took 2 days before the trouble occurred again and it usually occurred after a 10-15mn sleep. After a few days it occurred instantly.
Tablet is full stock, wiped again and again, reflashed, whatever. Full charge, middle charge is the same.
I do hope for a replacement this time.

That's a different problem, I was having having that issue when i was running earlier versions of CleanROM but since the 3.1 update I haven't had that issue. That issue the tablet is frozen or stuck in sleep my issue is the tablet is off completely. But there are are others in that thread posting about having issues similar to mine.

I think the shutdown may caused by a few issues, no don't considered every shutdown is the same. One maybe hardware, one maybe hardware. I suggest to try everything before you ship it back. In my case, I removed my keyboard dock and charge it over night BY ITSELF, then charge your tablet also by itself, put them together then I do a factory reset, then re flash a full Asus firmware. After that I never seen this issue again.

I'll try that when I get the chance but I turned the power save setting for the keyboard on and it stopped shutting down.

I've had my keyboard for a few weeks now. I shut the keyboard and open all the time. I have it so I can wake the tablet with the keyboard. Never had the tablet shutdown by itself. I'm stock, rooted and locked.
