Hi all,
Sorry in advance if I'm asking for something that has been answered before.
I have seen lots of threads that talked about the Asus Transformer tf101 and tf101G that doesn't charge correctly.
My TF101G stopped charging after it was fully drained after the kids played some games on it. When I plugged it in to charge the TF screen came on with a big battery indicator which showed a empty battery with red at the bottom. Then it just goes off. When trying to switch on again it just briefly flashes this battery and goes off again.
I left the TF to "charge" overnight and this morning after about 6 hours of charging it had +-14% battery life.
So it appears that the charger still trickle charges the TF when it completely off, but doesn't want to charge when it powered on.
Also, the TF recognizes the cable when it gets plugged in. If off and with some power in the battery the TF starts to boot up, but no charge indicator is showed when booted and battery drains as per normal.
Could it be that this is a software issue? I would guess not, but then again I ask myself if the charger or USB cable was broken then it wouldn't trickle charge. right?
Anyone came across this yet?
I know that some people suggested the freezer trick, but I don't want to do that before I checked on this with the community members here.
Many thanks in advance for your assistance and sorry again if I missed a similar thread.

It could. The charger cable got 2 red wires thats connected to the same point on the TF.
One of the wires is your normal +5v USB power, while the other is connected to a USB3 pin to tell the charger to spit out 15V instead of 5V.
If that particular cable is broken, the charger will only send 5V.
The odds that that small wire is broken though, is... well, very slim.
Hello,
I didn't use my tablet since 2 month and last week, i installed team EOS 4.2.2 JB rom.
After, my cable did'nt worked, When i tried to conect it to my computer, there was an error message that the tablet wasn't detect correctly.
And when i put the cable into the charger and the table to charge on the wall, i saw the icon on the right corner of the tablet charging but in the information battery, i sax that "Disconect" and the tablet % didn't grow up.... So i thought the cable was dead and i bouth one new on ebay.
With the new cable, no problem the tablet was detect and the charging with the charger was good. But after 2 days, i had new problems.
when i conect the tablet on my laptop, all is OK, the tablet is detect normally. But whn i try to charging with the charger on the wall, the tablet doesn't charge. I see the icon in the right corner is charging but in the battery informations, i see "disconect" again and the battery doesn't charge.
Yesterday, i saw a topic that i can put the charger on the freezer, i put it alle the night and i tried this morning but nothing the tablet does'nt charge.
On the charger, there is 2 parts, I open the little part with removing a screw and i tried to little move the 2 metal parts but nothing alwas the same problem.
So i think now the problem is not the new cable but the charger.... I know it's a specific voltage and if i try with my HTC ONE X charger, this will not work...
But maybe it's a problem with the tablet connect port?
I changed the rom and i installed the Cyanogen 4.2.2 this morning, and now when i conect the cable, with the computer, it's OK i see my tablet but the icon on the table isn't charging and i see "disconect in the battery information". And with the charger wall, it's the same, i have charge icon and i have disconect in the battery information
Do you think i must buy a new charger?
Sorry for my poor English my French
Try a trickle charge from the USB PC > Tablet
Plug the tablet cable into PC USB port and turn off the screen, then leave to trickle charge overnight
If you have the screen on it will not charge, so best to leave it off for a few hours to test if it is a charger problem

When you use PC USB to charge, it will not show charging on the screen, you have to leave it overnight for best test results
The freezer trick should only be used for about 20 minutes just to cool the charger down and reset the cutout
Try trickle charge overnight, if it works, its the charger
I think this is because tablet use a lot of power when in use and that is why the tablet is discharging when you use it. PC has even less powerful USB charger so the tablet will probably be recharging VERY slowly or even discharging when you use it.
You should leave tablet overnight to recharge and it is better to charge it in one piece than constantly plugging and unplugging it from PC.
Have a nice day,

You should be able to charge and use it at the same time with the actual charger plugged in, but you are correct, with the PC you can not use and charge unless you mod your USB ports for extra power
Ok i will try to conect the tablet (power off) all the night to my computer but i think it will not charge...
And if it's not work, it's not a problem with the cable because i can use the cable to transfer media PC> Tablet, so it's a problem on the tablet connector?
Hello,
My tablet was charging all the night. She was at 22% and now 38.... It's very slow!!! But now, i know that my tablet and my cable are OK and my charger is the problem.
There is a solution to repair my charger or i must buy an other?

Try this, separate charger and its pins, then take it along with the cable and put it in a zip pouch, now freeze for say 2 hrs. Take it out let it return to normal temperature and then try charging. Remember freeze them in a zip pouch (air tight)

Since some days I couldn't charge my tablet. The red led on the power button did not light when I plug in the charger. First I thought the port is completely broken but when I connect the tab to my pc I have the full access. My second thought was CM10.1, but I flashed the latest RC10.1.2. and it won't charge anyway. Besides I didn't read anything about such failure. Then I have tried with another charger but it also did not charge. Now I have only left 35% battery.
Is it possible that the micro-usb-port is broken for charging but not for connecting to the pc? It sounds a little bit strange to me. I just want to find out if it is hardware or software related.
Thanks for your help.

On my A510, I had a problem with the charger, by connecting via USB to my PC I was able to charge my tablet, something like 3% per hour XD
If it works for you too, that means that is might be your charger the problem (and not the tablet)

Obviously it is the charger. You are right. I have plugged in the tab with the charger of my Defy and 8! hours later it charged about 40%. So yes, it is the charger.
I will send back the tab because it is the same failure as it was with my A500. Now I will try the Xperia tablet Z.
Thanks anyway.

I am not sure what the problem is, so maybe someone can help me.
I have a tf101 whit docking not rooted or anything.
The battery is drained 1% I can start the tabled and it shuts down, exactly what you would expec. When i plug in the adapter directly in the docking or tablet alone. it does not say charching. When i leave the charger in the tablet it is actualy charching(over night it is 30%), but it is not saying that it is charging. When the battry is 30% and i leave the charger in and start up the tablet the battery drains to zero.
I have tried multiple cables and chargers and all simulair.
Anyone?
I just found out that it is charching whit the original charger again. Maybe the charger has been the issue over all.
For now the tablet is charging again and problem looks OK again I still think it is a combo of battey getting bad and bad charger.
