I'm wondering if anyone has experienced this. So far I've tried charging the dock for 9+ hours and when I unplug it, the LED still starts flashing as soon as I unplug it, indicating less than 10%~ battery left. I don't think this dock ever got a full charge ever.
Am I doing something wrong, or should I RMA the dock?
Bump, see if anyone knows the answer.
Is the charger getting hot when you plug it into the keyboard dock?
No, it doesn't get any hotter, but I know that it's passing power to the tablet, since the cable goes into the Mobile Dock and the Tablet is docked, the tablet gets a charged to 100%, but Mobile Dock doesn't
Remove the tablet part and just charge the dock on its own.
yep. charge them separately. i believe that if they are connected the tablet fills to 100% before the dock even starts to charge ....

Tried it, over 10+ hours, still the LED starts flashing as soon as I unplug it.
I think I may have to RMA

I got same problem too.
but the charger is hot while I charge tablet or dock or both together.
dock is not charge, it always 0%.
sorry for my bad on english
Is the dock FW up to date ?
TBH .. i'd just RMA it, if its under warranty, just get it sent back.
P.S. Download the dual battery widget to see what it displays for the dock power ... but still RMA it.
Hi there!
I have a B80 Tablet which was working properly as it should, until on Wednesday I left it completely dry (both dock and tablet 0%) and now they won't charge at all!
The wall charger and cable were tested with my friends TF101 - working fine, no problems at all.
Also when I turned on in the evening it showed the Battery (with red status) icon which means it needs to be charged - I put it on the wal charger for 3 hours and the dock was not charged at all, and the tablet got 3% juice and that was it.
Neither the dock or tablet is charging - tried them separately
Also tried cold-boot, the "freezer trick", the USB trick - no success
Any suggestions? Experience?
Thanks!
P.S: 3.2.1 HC, KRAKD ROM, default kernel, no OC
Mine is doing something similar. Tablet will charge but keyboard won't. If I leave tablet connected to keyboard I will draining completely in less then 4 hours. I have the OG Transformer 101.
ICS (revolver tf101 4.0.0 RC1 with stock kernel)

Now I managed to get the tablet to 9% Via USB Port -.-
Also tested my friend's charger which works as well - but mine does not want to charge...
Ive got exactly the same problem with one exception, i am not able to charge it at all!! After all night connected to charget still 0% battery, in dual batter widget there is unknown battery error. Charger is ok. Dock is fully chargedand even from dock my tablet wont charge.
What is more i am not able to flash stock rom with nvflash, it disconnects after sending bootloader.
Do you have any ideas what to do now?

Just a few questions:
I plugged the dock on the wall charger without the tablet - it shows no life signs. Isn't the LED should be blinking? Also left the tablet on the wall charger for 2 hours and the battery was charged a bit (10%) - so it can't be the charger.
Also since it got a little charge - it can be hardware error with the battery. A loose cable?
Also managed to go back to stock ROM and no help - can it be that the cable has issues?
Battery voltage shows 7V BTW currently
Have you guys try using PC USB port alone and charge the tablet for like a day?
Put the tablet OFF and let it charge thru the day(12hrs) and see what happen.
Next, dock the tablet to it's keyboard and fire up. Go to settings - Developer options - USB debugging(uncheck).
Go to Settings - Asus customised setting - MobileDock Battery mode(uncheck).
Still docking, now restart the TF101.
And yes, the dock would blink when charging take place until it turn green when full charged..
Just tablet wouldn't charge
I have a similar same issue. It was working fine and then when i went to pick it up to use it wouldn't start up. So I followed all the tips i can find so far but no dice. Here are the rest of the info:
The unit will not turn on if I don't have the power cable plugged in.
1) When the cable is pulled out, the unit turns off and will not turn back on
2) When the cable is plugged in, it turns on and work just fine
3) When I put it on the keyboard dock, it turns on and work just fine
4) When I pull it out of the keyboard, it turns off and will not turn back on
5) I have soft reset, hard reset and factory reset (all with power plugged in) because nothing will happen without the power plugged in
6) Battery status shows 86% but not charging:
--When plugged into the wall
7) Battery status shows 86% but not charging while in the dock.
--The dock battery shows that it is charging and the light on the dock is green
I have tested and knows the charger works and the dock battery works.
The main unit battery will not deplete and will not charge.
What do I need to do?

Ive done exactly the same tests, and behaviour of my tablet is almost the same (battery 0%)
I am waiting for a responce from Asus.
Honestly speaking i am glad to hear that someone else has the same problems and the same symptoms. It means that the Asus hardware or ICS update messed something up.

I hope ASUS says something, becuase this is driving me crazy - out of the blue suddenly not working.
I charged the tablet via USB overnight - 46% right now, but the dock does not want to go up from 0%
And it looks like it charges via the wall charger as well, but it is the same as via USB - so the "real" charging is not triggered.
Fixed!!!
Looks like the wall charger charged with 5V, but not with 15V properly - which is utterly strange.
Waiting for a new replacement charger - with 12V 1A should be working.
BTW, if you want to do this, there are already threads.
You need a Molex Female and a USB Female cable - wire it like on the picture.
Yellow cable from Molex to USB red and the black cable from Molex (next to the red) to USB Black - that's it.
Great that it works for you but I don't think that is my problem though. I can't get it to trickle charge from the USB even. And the battery widget said "battery health = unknown error".
I guess I will still wait...

My charger is 100% good (tested on my friends tablet). Besides it should charge from dock but it doesnt!
Still waiting for asus responce.

GOOD NEWS! Tired this and keyboard showed 99%. I will need to run power down and try to charge later to see if fixed completely.
Now for what I did.
Took the base AC charger from my Galaxy Nexus, any base should work, then used the standard USB cable that came with the Transformer and plugged it into the AC charger and the keyboard dock without tablet attached. Plugged into the wall and got nothing. No lights or anything. Then switched back to the AC charger base that came with the Transformer. Plugged into wall and I got a green light on the keyboard dock so I then docked the tablet. The dual battery widget showed 17% tablet and 99% dock. At last check it was 27% tablet and 99% dock.
Hope this is a fix.

Hi davebugyi, so if I understand correctly, the solution is to use a 12V 1A USB charger to revive the battery of a dead dock? I have the issue as per my post here
Needless to say the dead dock battery is driving me mad!! Even opened up the dock and flipped the battery switch inside!!

Thanks so much for this. This just happened to me too and was tearing my hair out why it wouldn't charge. Done trickle usb charge for 5 min from my phone plug and then plugged normal charger in again and instead of 0% it was at 33% and is now charging again.
Hope This helps
I had this problem for so long, that i even gave up on looking for fixes.
the problem was that i remember dropping my adapter accidentally, so it became loose. but I didn't know this, I thought the cable was faulty. so simple fix...if your adaptor is loose, try fitting it in place.
sorry for my bad sentence structure and bad description, hope it helps
Two days ago, I turned my Infinity off and docked it. Both batteries were fully charged. A few hours ago I picked it up again, and the tablet wouldn't turn on.
I plugged it into the wall outlet. It started charging and I was able to turn on the device. It had 0% charge, and the batteries on the dock were also dead. What I don't understand is: how can the Infinity and the dock discharge completely in that time even though it was supposed to be off?
I left it plugged in so that I could use it while it charges. After some time, it asked me to connect the charger and then turned itself off due to almost dead batteries. Cable was still plugged in, though the charging light was off.
Tried connecting the cable to the dock, no light. Tried connecting the cable to my computer, it didn't work. So, the cable must be faulty, right? I can still turn the Infinity on, it'll boot normally and turn itself off after it's reached the lock screen. There's a red exclamation mark on the battery icon that wasn't there in the first time I turned it on, does it mean anything serious?
I had it drain to zero once overnight. Wasn't completely charged but it was strange... hasn't happened since in fact it generally has very good battery life.
I would definitely try a new cable and or charger.
Yeah, I've asked the store for a new cable. They'll have to mail it to me, so my tablet will stay dead for a few days. Now I know why propietary connectors suck.
Anyway, it seems I'm not the only one that had problems with the charger. Many people have reported overheating, but that never happened to me. The adapter that came with my Infinity seems to be a newer model; the plugs can't be folded or detached.
Charger: I had that happened several times to the SL101. Turned out I had something else plugged into the USB and the adapter was overloaded and tripped. Unplugged for a little while for it to cool down and reset itself.
What do you mean you had something else plugged into the USB?
Anyway, I've left my adapter alone for quite some time. I'll go see if it works as soon as I get home.

I was charging a small 700 mAh battery through the USB. That was enough to trip the AC adapter.
My cable broke, and a friend gave me his (from a TF201). It charges my tablet, both docked and undocked, but it doesn't charges te keyboard. The energy passes through the keyboard to the tab, but the keyboard itself doesn't charge at all, it's always on 0%. How can I make it charge? Thanks!
[Ignore my poor english]
Sounds like electronic in your keyboard is not working.

If you let your dock battery reach 0%, it might never charge again, you should never let them reach 0%
You can try opening it, there is a small switch on the board inside, flip it and try charging for an hour, then flip it back and try charging fully
I did it once and that worked - might have been coincidence though
Have you tried charging the dock without the tablet attached? Mine did the same thing until I did this. I just waited until the little light on the side went green. Works fine now.
Yep, i tried everything. I'll open it tomorrow to check for that switch *Detection* talked about. Thanks!
Have you tried charging just the dock trough usb for 30 - 60 minutes?
I once had the dock @ 0%, wouldn't charge on the net charger, but after "trickle" charging trough usb for ± an hour further charging on the net adapter worked.
I have searched through the forum and tried all suggestions found, attempted to charge using a wallwart (known to be good) and USB (cable known to be good). Some background: last fall I was trying to flash the ROM and it got stuck in a boot loop. As I was visiting my wife in Taiwan (she teaches at a university there), I decided to take it to ASUS to have it looked at. They diagnosed a bad motherboard and replaced it, but not in time for me to take it home. It could not be shipped back because of the expense of shipping a lithium battery powered product was $$$$$. She brought it back with her and the battery showed as 80% charged (but the dock was out of juice).
I attempted to charge it normally, and nothing would charge, the tablet kept losing charge. I then attempted to charge just the tablet with the wall wart, and it would not charge. I tried a cold boot- no change. I tried turning off the tablet and charging it via the usb port of my powerbook overnight, and it did charge (not completely) and I then tried to finish charging it with the wall wart. It would not take a further charge. I am now attempting to bring it to a full charge via the usb port.
I tried charging the keyboard/dock via the usb port of the powerbook overnight, and it did not seem to charge. The keyboard will input to the tablet when connected, though, but there is no indication that the dock battery is active at all.
At this point, I am at a loss as to how to proceed. I suspect that the battery died for lack of a charge for such a long time (end of November to January 12) and that it must be replaced, but I am eager for some feedback from more experienced hands.
I also want to get it up and running on lollipop, but that will have to wait until this is resolved.
TIA!

Wallwart: How do you know it is good? Is it original Asus? Most usb chargers put out 5v, this tablet needs 15v. If you charge via PC USB port it's 5v, called a trickle charge and takes forever. Not even LEDs come on although it charges very slowly.
I suspect the wallwart or - if the cable is not original - the USB cable (even if it works with other devices).

"No indication" meaning you do not see the dock battery icon in the notification bar?
By design the tablet gets charged first, then the dock battery. If you do this at 5V, you'll wait 'til kingdom comes...

Take the combo to a store, ask them to use a original Asus charger. The dock battery may be busted, but my money is on the wallwart.
Thanks for your reply, I appreciate it!

I charged my phone with it (iPhone 5, charged fully in the normal amount of time. I have a multimeter if that would help. I tried 2 different usb cables, both of which worked with the tablet for a slow charge via usb

Correct, I saw only one battery indicator, which, seems like it is the tablet, as the same data appears undocked

I see little point in that, under the circumstances. I have charged the table 100% via the usb cable, I will see if it now accepts a charge from the wallwart.

It won't. Not from a wallwart for an iPhone. You need a charger that outputs 15v.
If your battery icon doesn't show (even if it's empty) you either have a problem in the dock connector or the battery is totally dead. I think you'll find instructions to replace it on ifixit.com

the wallwart was the Asus one that I charged the iphone with (not the iphone one), that is how I tested it. the iphone supposedly draws 12W, BTW
