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've never had any problems with charging before until today I finally found a keyboard dock for my Asus Transformer. I plugged it in and tried to charge it but it was not charging. Then I unplugged the keyboard dock and my tablet itself would not charge. Did docking the tablet cause this problem (maybe the update it installed upon plugging it in) or is it a coicidence that my cable just stopped working. Either way I'm freaking out!
I may have the same issue or a simiar issue before with the charging but later I found out it wont charge when it at a certain percentage. Basicly if the % around 95 then it wont charge but for example you at 70% then it should start charging again. i would say it like a preventative measure to prevent over charging. If that was the case then this should be the reason.
On a side note I recommend dling dual battery widget so you know how much batter your dock have and tablet so you will not be charging it all the time thinking it might be out soon.
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

When you plugged the dock in to the usb, did you get a light on the dock? having the same problem!
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.
I've successfully replaced the battery of the dock with a new one. It was showing some charge 36% instead of 0% and no more tablet draining, but it never charged! So now it's at 9%, red dot blinking, and I don't know how to fix it! Charging sign appears when plugged in and tablet charges trough the dock.
I've tried the cold boot and the trickle charge but I didn't see changes, maybe I've done something wrong?
What more can I do to make it charge again?
I thought it was the charger or the cable but for what I see the 40-pin connector has actually only the 4 pins (the usb signal) so I don't think I need another cable.

I don't believe it is a software issue. It might be a contact issue caused by yourself I think.
Firstly disconnect your tablet from the dock. Connect it with the charger and check if it is going to be charged. If so, your both charger and cable are OK.
Secondly check whether all contacts between the battery and the dock are closed correctly or not. Please follow backwards the sequence you used to taking out the old battery by yourself.
try and charge it with the official charging brick, or at least something that can put out 15V at 1.5A i had the same problem when using my tablet after a long time and only my tablet would get charged not the dock
Yes I'm charging it with the official charger, maybe it got some problems
I don't have a tester at the moment but I got a doubt. Is it possibile that the cable has 2 charging lines one for the tablet and one for the dock? Because I want to buy another charger but maybe it could be not compatible for charging also the dock.
I opened it again last weekend and there was nothing unplugged, everything was good.
