[Q] Asus Transformer Dock not Charging [SOLVED]

Just got the dock a few days ago and it charged up fine the first day. Then a few minor glitches started.... the tablet wouldn't wake up from keyboard input or trackpad input. Now, the dock wont charge at all.
Dual battery widget shows it at 0%, and when I apply the charging cable, the LED shows green (when the tablet is at 100%). So it's almost as if it doesn't even see the dock battery.
Any ideas?
UPDATE: This issue has been SOLVED! See post #3 for my solution.

If you just got it, then it is in waranty. I would send it back for repair since they will replace it with a functioning one. My dock did this (although it was, like, a week after my newegg waranty expired) and I sent it into asus and they replaced it in a little under 5 days.
On a side note, have you tried removing the transformer, waiting about 10-15 seconds, and then replacing the transformer back on the dock (while the dock is not charging). Also, does the transformer show it is charging when you put it in the dock with under 90% charge? The dual battery widget sometimes says I have no charge on my dock when I clearly do. To fix it I just remove my transformer from the dock, wait a little, and put it back in aaaand: voila, it works perfectly.
Oh yea, and try disabling "power saving mode" in the settings under input if you want to wake up your tablet with the keyboard or trackpad.

Dyskmaster,
Thanks for the tips. I tried all of your suggestions, and nothing worked. The weird part was - every time I plugged in the dock, the light displayed solid green (indicating 100% charge on both batteries), but dual battery showed 0% charge on the dock. This got me thinking that the dual battery widget was not reporting correctly.
I then found a tip on another Android forum that suggested plugging in the dock to a USB port on a PC - waiting 5-10 minutes - and then trying the AC wall charger again. I did this, and boom.. the dual battery widget showed 100% on both batteries.
It's been working fine for about a week now, with no repeats... I have no idea what the problem was. My only guess is that the dual battery widget freaked out the first time the dock went to 0% charge. It seems it's reporting fine though now, even after the dock hits 0%.

I have this problem too, the led in dock always blinking in orange and dual battery always shows 0% ( of Dock) and i also changed the charger and changed the roms , but still not charging, what should i do?

Fixed for me too
I had RMA's my TF101 as it had completely died on my following ICS upgrade, Asus returned my tablet with ICS 4.0.3. For around 3 days I was using it very happily, no more reboots, no screens of death, I was so happy.
Then one morning after recharging my tablet while docked, I checked the dual battery monitor and it showed the dock battery rapidly fluctuating from 100% to 0%, it would show fully charged when plugged into the wall.
I was about to RMA the keyboard when I saw your post, plugged the keyboard into my laptop USB, left it probably 5 mins, then attacehed the tablet, dual battery widget showing both batteries correctly and no flucuating readings.
Thanks again

[Q] Tablet and Dock not charging - cable is OK _ Wall charger fail [Solved]

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

Tf201 Dock won't charge

Just bought a used TF201 dock, but Im not sure it works properly! How do I see the firmware version? How do l see how much the battery is charged on the dock? The widget with both batteries says 0% in the dock even though it has changed for many hours.
If I press on the Dock Connected sign it just says 0%. The LED lamp of the dock flashes red when its charging, not constant red as the tablet does.
Is the dock defective or why won't it charge? Does it need firmware update? I can use all the other functions of the dock BTW.
It says 'TF201-DOCK-0207'
is that the correct firmware? How do I update the firmware?

That's really weird. It should be solid red when charging the dock. Im assuming you tried a reboot with the dock plugged in. If you plug the charger into the tablet does a charging insignia show up? If not then you probably don't have enough voltage to charge the dock as you would be "trickle charging" the tablet

If its not a voltage issue then you may have a bad charger, bad dock keyboard or bad tablet. I would first test the charger and tablet first. If that proves to work I.E. the tablet charges then I would move the tablet and charge the dock keyboar. If that works then insert the tablet into the dock keyboard and see if the charger will do both. Remember that the tablet will NOT charge the tablet with. It's battery until the tablets. Battery goes below the 70% threshold.

The adapter charges the tablet with or without the dock. The dock however doesn´t recharge whether its with the tablet or not :crying:

By what you're describing you aren't actually charging the dock is what people are saying. Usually charge is constant orange/red not flashing. If it is flashing when you are charging something is wrong. Does the dock go to green when on the charger for a period of time like a few hours? If not it's not charging.

The dock doesn't charge. No matter how long its in the tablets charger it just blinks red. Even after being charged all night it still flashes red. No constant red or green.

Sounds like the dock is bad. If it's under warranty send it in but don't tell them you're using it with a TF700 just say it won't charge with or without a tablet inserted

Yeah, I think I'll do that. Bought "Used - as new" through Amazon

[Q] turned off for a long time and now won't start

Hey all, I have a stock tf700t that was working well until the charger cable snapped. Several months passed before the replacement cable arrived. So I put it on to charge overnight, and got both the orange light initially and then the green led to say it was fully charged. But I can't get it to respond to any attempts to turn on. I tried the usual
Pwr held for 30 sec.
Pwr and volume buttons
and stincking a pin in the reset hole
- but nothing happens. no vibration or LCD response?
Reading some forums, I tried to use a PC USB port to trickle charge the device, but interestingly this does not light the LED's.
Any ideas as to what is happening?

Do you remember the charge state before you stored it? Li-ion batteries generally don't like being stored in a totally discharged condition, and if the voltage drops below a critical level, the battery can even be permanently damaged.
Try charging the tablet from a PC USB port (directly - not via the dock) - it's normal that in this case the LED does not light up.

thanks for the advice, I am pretty sure it would have been <5% battery, maybe even lower. I hope the battery is okay, and will try your idea.

The trickle charge via USB takes a long time. Leave it connected for at least 6 hours and make sure your PC doesn't hibernate or sleep.

Help - Dock not charging

Hello i have a problem with the tablet dock
The tablet was just stored for a long time and i got a new charger because i lost the old one, the tablet works fine but the dock stays at 0% no matter what
i flipped the switch inside the dock like once or twice a day over a week but its still at 0%
I have switched the battery from the tablet wich was at 100% to the dock and the tablet got charged like no problem but the dock it still not charging, right now its at around 80% it got discharged a little over some weeks .
The keyboard works with no problem its just not getting charge or charging the tablet when docked but if i connect the charger to the keyboard while docked it charges the tablet
I hope someone can help me

Sounds like the charging circuit is fried in the dock if the battery charges fine in the tablet

is there any way to test it that you know?

Buy a new charging board and replace it
Other than asking someone with a lot of micro-electronics knowledge to test it, that's the only thing I can think of
They are so cheap now though, it would be easier to just buy another one, you can get both tablet and dock on ebay for £99, or the dock for around £40
Usually when they are stored for a long time, the batteries drain and once they hit 0%, they won't charge again, but if you say that battery still works fine in the tablet half, and the dock can still charge the tablet, then it sounds like it's the actual dock charging circuit at fault, can't think of anything else other than connections being loose between the battery and the dock

The dock battery not working properly
Hi, i have Transformer TF101 (KTU87Q KaTKiss-4.4.4_036) after some time the battery in my dock stops working (icon dock battery display still 0% and red exclamation mark)and while charging the battery dock is still flashing red light. I replaced the battery for genuine type, battery can be charged (green light while full charging - OK) BUT when I turn on the tablet, then some time icon shows 0% and red exclamation mark after that for example 96%, when the tablet battery is discharged, transfomer shuts down and the icon dock battery still display example 94% What is wrong?
I made a battery calibration but nothing has changed.
Why new replaced genuine dock battery not working?
Thank you

I recently had a dock that had the same problem. Everything worked fine except that it would not charge a known working battery. Make sure that you have the switch in the correct position. From what I recall, the switch has markings on it that show in one position "0" and the other "1", similar to a power source switch on a desktop computer. You want it in the "1" position.
Also, does the battery indicator light come on when the battery is less than 90% and you are connected to the charger? Are you using a OEM ASUS TF-101 cable and power adapter?
It may be that the dock has a hardware problem in which case the only thing that will fix it is a new board. Not really worth fixing as this is now 4+ years old and there are many devices that can be purchased brand new for the price of fixing the dock which are vastly superior to the TF101.
