Charging from a PC/Laptop only works when the TF101 is powered off and left for a long time, such as overnight
It is called Trickle Charge
Connect the TF101 to the laptop USB, Power Off the TF101, leave overnight
Check the next day
If it is still not charged, you might need a new USB cable

[Q] battery not charging

So is it charging or not charging? Your post kinda confusing hence no one answer. It doe not show that it's charging on the tablet but is the battery itself being charge or not?

I plug it into the computer via the usb cable, and it does not charge. It usually does charge when i plug it in.
Mine just started doing that right now! I plug it in to the AC charger and doesn't show it charging, says not plugged in. Then I put it on the keyboard and try to charge the keyboard and still says not plugged. I also tried connecting it to my pc, and my pc reads it but still doens't charge. I also just updated from HC 2 days ago. Not sure if that has anything to do with it.

Usually with the USB to PC it will trickle charge while the screen is off or TF turned OFF. It just doesn't put out enough power to fully charge the TF in a quick manner.
Did you recently change anything on your TF? Like update ROM ect...?
Many peoples have the same problems with ICS

that's weird, because it never did this before. if i updated it to jb, would this fix it? is there a known issue with this in ics? and so my battery does charge when it is off? why only a trickle charge? no, i have not updated/flashed any roms to it.
Have a look at my post on a similar issue: (http://forum.xda-developers.com/showpost.php?p=31612760&postcount=2)

i don't understand why I would need a new cable, or why it would fix it, when the cable works fine for syncing. also, why does it not do a regular charge?

So did mine. no data problems, but it would only trickle charge from ac or usb. I inspected every mm of the cable and couldn't find a problem with it but the new cable worked straight away. I imagine the problem was with worn pins

that's weird. i don't think i would have used mine too much, for the pins to wear out. but you said that yours would trickle charge in ac. mine will do the full charge in the ac. so maybe there is something else wrong with mine?

No you cant change it. Unlike lets say a smart phone that will charge at like 5v the TF101 needs 12v-15v to activate fast charge. anything under 12v will trickle charge the TF101 and usb's dont not supply 12v, it would do no harm if they did aka the ac charger does exactly that.

so that's why the battery icon shows it's not charging then. it's just the trickle charge. any way to really confirm this? i just want to make sure it is actually doing this.

Well drain you battery to lets say 60%, shut it down, plug it into your pc then check the battery levels after an hour or two. then compare it with an ac charge.
ok i got mine working! I read on a thread that someone posted about the heat sensor inside of the AC charger box that trips. So what they said to do was put it in a sandwich bag and take out all of the air and seal it, then put it in the fridge. I forgot about it and left it for a day! haha. Well i just took it out blew on it a bit to take off the humidity, plugged it in and now its charging.

That the way but I find out another ways:
- take your AC out power point and leave it couple hours or longer and then plug back it'll be work:fingers-crossed:
- After charge or none used anymore unplug AC from power point (not turn off switcher) never leaved it there
because the heat sensor inside of the AC charger

[Q] TF101 only charges when completely shutdown?

I am having the weirdest problem on my Asus Transformer TF101 . I had updated to ICS via ASUS's check update option and then it stopped charging at all ( I do not have the dock, just the wallwart) .... . It would not charge ( not even show a charge flash symbol on the battery ) when the tablet is on AND plugged in..It would ONLY charge with the Wallwart when the tab is completely shutdown .i.e. I would have to shutdown the tab completely and then plug it in so that it can trickle charge over night to +80%. I changed the cable , changed the wall wart same issue... Then I thought its possibly a sw issue so I resetted , wiped caches, reset battery stats and even upgraded the sw to a Rayman's CyanogenMod 10 ♦ B4 ( currently running it ) .. Now I can at least see a small charge flash symbol when the tab is plugged in but instead of charging the tab , when I look at the battery status it shows discharging.... I can only charge this dang thing when its completely shutdown.. I still think its a sw issue.. Wondering anyone else had this issue and more importantly what is the fix ?? ..
Fixes I found in the forum that I've tried so far :
1. check/uncheck the stay awake option
2. Rooted ,installed Rayman's CM10-B4 rom
3. install dual battery app to check battery stats,( dont know why was this suggested as a fix )
4. wiped battery stats in recovery mode , thrice
5. changed usb cable
6. Put the charger/wallwart in freezer overnight and then check the charging ..
I'm outta warranty duration so desperately need to fix this on my own ..
You are using the ASUS TF101 supplied charger with its included cable, and nothing else? I.e. no extension USB cord etc.
The ASUS TF101 charges using 12-15V from the wallwart, not the standard USB 5V. Using standard USB, it's only able to trickle charge during power off, and this sounds exactly as what you are describing.
I had the same problem a couple of weeks ago. I even tried the freezer trick too in desperation as it was my last resort before admitting defeat in my battle with trickle charging. In the end I purchased this charger off ebay:
http://www.ebay.co.uk/itm/140714910102?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I know it's advertised as a UK charger but if you read further down the page they ship the US and EU charger too. I've had it for about a week now and it works perfectly. I was dubious about buying a non Asus charger after reading reviews about them on Amazon about overheating but mine seems fine. If anything it's actually cooler than the original one.

I have tested with the same USB cable that came with it originally and the wall wart is original too. I changed the wall wart and USB to see if there's a difference but apparently none. Not using any USB hubs either...

Sorry to disagree, but everything you describe sounds as a charger issue to me, not a SW issue. If it happens even with the TF powered off this makes me almost sure...
Sometimes it's good to start from the begining, although you think you have tried everything...
Get your TF, your asus original wall adapter and cable and try it. Does it work?
If not try another outlet on your house. Does it work?
If not, you may even try another outlet (work, school, whatever). Does it work?
If not exchange only the wall adapter (for another asus original one if possible) and start over.
If nothing changes, get back to your wall charger, change the USB charging cable and start again.
If nothing changes, change wall adapter + cable and start again.
Remember... The TF will only charge with the asus wall adapter and cable or a specific charger. If you try to use your computer's USB or a wall adapter from a phone / generic USB device you won't get any charge at all, and will only trickle charge when the TF is off.

Sounds like there is an issue that the charger is not recognizing that an Eee Pad is attached. Might be time for a new charger.
Hello all, I have the exact same problem. I received my Asus TF101 for Christmas last year. Then later I found out that you need it root it in order to upgrade the OS. I rooted my TF, then I upgrade it the OS from Honeycomb(4.0.3) to Jellybean(4.1.2), (4.2.2) A month later after upgrading the OS my battery drain faster and I can only charge the battery with my TF turned off. If I plugged the the charger while its on it, the battery says its not charging. I change the wall wart and the cable but the issue still persist. Please help!!!

Is the new wall wart you are using a genuine Asus wall wart? If it is just a tablet USB charger, that will not work as the TF101 needs 15 VDC to charge instead of the standard 5 VDC of USB. The Asus wall wart auto-detects and switches between the two voltages to allow it to be used for other devices as well.

[Q] My TF don´t turn on or even turn the light on when I plug it

Yesterday I was using the Tf when my batery level go down so I plug it to the wall charger, A couple of hours later I tried to turn on the device but nothing happened even any light was on. Till that I can´t switch on my tablet.
Please help
Was the charging light on the tablet on when you plugged it to the charger? What color was the LED? Trying to determine if it was charging.
When I plugged it everything was normal a batery came up in the lcd but after a few hours when I tried to use the tablet allso the screen and the led were down

I try everything press the power boton for 30 seconds, volume down... etc all I read. But one strange thing is that if I connect the usb cable first to my laptop and then to the tablet my laptop restart without reasson.
Are the pins on the power cable or the tablet bent or broken? Maybe try to turn on the tablet when it's plugged into the power cable? Also, you can try to let it sit for 24hours (maybe longer) to see if whatever power is left in the battery completely dies. Then try plugging it in again to power cable and hit power button to see if it powers up.

You tried to charge it via the USB cable and your laptop? I do not believe your laptop's battery can deliver enough juice to actually charge the 700, so then it wouldn't surprise me the 700's battery is as dead as a dodo. Try the wall charger instead.

It is also possible the wall charger failed. I had this happen when mine was a month old. I could only charge off of my usb 3 on the back of my big pc until I was able to get another.

If none of that worked, I would say to call ASUS for a possible hardware RMA.

[Q] Problem with charger

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.

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)

[Q] [A700] can't charge but connect to PC

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.
Alex
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.
