Just wondering if anyone has experienced the following issue:
I've tried charging the TF from the dock with the lid/screen down.. when I lift the screen to check some time later (say an hour or so) - the charge doesn't appear to have increased. When I unlock and go to the homescreen, the lightning bolt has disappeared - only to appear a few moments later, presumably to signify that charging has resumed.. Its a UK TF & Dock, therefore no new firmware yet.. Is this happening because there's been one of the infamous "dock disconnects" at some point during the charging phase?
Tried my second test this afternoon - left WiFi to always on, but put the TF in airport mode this time.. same "pausing" of charging... My original post from last night's weirdness below:
----------------------------------------------
Question here for anyone who can help shed some light on what's going on..
If a Dock is fully charged, and a TF is almost depleted (e.g. 1-4% charge left).. will the dock fully recharge the tablet to 100% or near enough?
The reason I ask is because I tried just that scenario last night.. made sure the doc was fully charged (leaving it plugged into the mains) and then docked my TF into it when it was at about 2% and removed the mains... shut the lid and left it..
Some time later I popped open the lid and checked, it was up to about 49%... so I closed the lid and left it over night...
And here's where some weirdness started happening..
Checking it this morning by lifting the lid, the tablet reported the same charge value of 49% with no lightning bolt in the notification area.. a few moments later, the lightning bolt appeared and it continued to charge from the dock and checking the battery usage graph confirmed that it had only charged to a certain point and simply stopped. With the lid open (but screen off) the tablet continued to charge off the dock upto about 62% at which point the lightning bolt disappeared and the dock light was flashing orange...
I'm on a UK tablet and dock (so no new firmware update yet), and I have the "WiFi off when screen off" mode selected - not that that option should have any affect (the wifi was indeed off all that time the screen was off - but so it seems was the charging)
I don't think I've got a duff dock, but can anyone confirm they've experienced similar... that the dock doesn't fully recharge the tablet or offer some other explanation plz?
--------------------------------
It could be the dock disconnect issue. Mine used to disconnect when it was locked, but now its fine after the update.
Just to be clear, your charging it using the wall adapter correct?
Charging the dock via wall adaptor, disconnect it once fully charged.. docking the TF and seeing how well the dock charges the TF on its own..
I tried putting the WiFi back to 'always on' with Airplane mode off.. and surprise surprise it seems to be charging with the lid down and screen off.. wake it up, lightning bolt still there and still charging.. some how the wifi power saving mode must be linked.. dock disconnects probably also an issue.. any thoughts?
A few thoughts.
The dock can only charge the pad to about 55-60%. This is listed in the specs.
When doc with pad are on the charger the pad will be charged first and then the dock. This is by design.
What is up with the UK units not getting the OTA that fixes most of the dock issues (Wifi, sleep, etc)?
I have been charging my dock and tablet together since I got it, which has been for about two or three chargers, and I have the latest firmware updates. What I noticed is that my tablet was at about 78% and the dock was blinking orange, indicating that it was less than 10%. I plugged them both in and in about 3 hours the dock light turned back to green, indicating that it was charged, and my tablet shows 100% charge with no lightning bolt, meaning that the dock isn't charging it. What surprises me is that the last time I charged it the tablet stayed at 100% for quite some time but then the dock started blinking orange again. From what I have read and understood, the dock isn't suppose to charge the tablet until it reaches a certain perentage, but apparently the dock is charging the tablet even when the tablet is somewhat fully charged. I'm going to see how it acts this time around and see if we can get to the bottom of the issue of how the dock and tablet are charging together.
I am assuming that you are having a problem with the dock and tablet not charging together because you have the disconnect issue, which should be fixed once you get the latest firmware update.
Well that 60% charging tallies with what I've just witnessed... the dock charged the tablet to 66% before giving out.. but I had to put the TF into "WiFi always on mode" before it would charge with the lid down (compared to the "charging sleep" that I was experiencing in either Airplane mode or "WiFi off when screen off" modes)
Wonder if that's been fixed with the firmware update.. can anyone with the update confirm that the tablet will charge in those other WiFi powersaving modes?
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
If I have the tablet docked to the keyboard, what gets charged when I have the charger plugged in? The dock (since that is the only thing that has an exposed charging port once docked)? Or the tablet? Or both?
Also, when does the dock start charging the keyboard? Anytime it is pluggedin, or only when the tablet reaches below a certain point? Can we change that threshold? Can we force the dock to charge the tablet on the fly?
1. You can see the charging lights on both the dock and the tablet when you plug the dock in with the tablet docked (and they're both low charged). Both get charged, in other words, though if one is charged, only the one that's low gets charged.
2. It's not automatic. If the tablet has a charge over 75%, it doesn't seem like the dock charges it. Once the tablet is below 70% or so, then the dock will start to charge it. If you use the Asus power widget, it shows you when each is charging.
thanks.
What happens if you are docked and you plug the usb cable into the dock and then into the PC?
Can you get MTP card access that way?
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
Meldo

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.
I have two TF300t
one is mine (blue), bought with keyboard dock in sep/2012, unlocked and with a custom room (katkiss)
the other is from my mother (grey), bought with dock in apr/2013, locked and with asus oficial updates
last week I was traveling and when I came back, my mother was using my tablet because the grey one was not charging
when I plugged the grey in charge he didnt respond. no led. neither in tablet or in dock.
I tried to use the blue dock with 35% battery in the grey tablet, but nothing happened
When I plugged back the blue dock in the blue tablet, the tablet showed the % battery on the dock, but the dock doesn't charged the tablet.
So, i plugged the blue dock in charging. The battery reached 100%, but the blue tablet didnt charged.
I tried to charge the blue tablet, but nothing happened. Tried to plug in computer USB port, both PC and tablet reconized. Selected 'charging only', but nothing happened, just the orange led turned on.
Tried to charged with PC with tablet off, same thing, orange turned on, but no charging.
Now, the blue and the grey tablets and the grey dock has no battery. The blue dock has 100%.
Tried to reset both, but with no battery I think this wont work.
I leaved both tablets and the grey dock charging for hours, but I got nothing.
Both tablets are with no battery. One dock is fully charged.
What can I do now??
