guys, I am having this problem from day 2 of having TF. First day was charging fine. Second day I had to play with the wire and reset the device then it charged. Today, NO CHARGING AT ALL!!!!
I tried to the piece that goes to the AC out , but still nothing happening. I connected to my PC, and it recognizes the TF and I can view its files, but with no charging!! Is that normal or what??? Does yours charge when you connected to your PC?? What should I do? Should I call Asus? if yes, what number? or should I return it to Best Buy.??
Help, please ....
I don't think the TF charges when connected to a computer but others have said it does but at a very slow rate. I've heard others say it does slowly only w the screen off as well.
It sounds like you may have a defective charger or charger port on the TF.
Do you have any other USB AC plug adaptors you could try? I know many of them don't put out the same power but may be worth a shot.

I tried a different USB AC plug, but no luck. I guess I am going to return it to Best Buy.
You need to make sure your using the USB cable that came with the TF and the outlet device that came with the cable/TF...
The TF charges at a higher rate than USB from the PC. So, the TF uses a USB 3.0 cable (included - most cables purchased are USB 2.0) which had more pins and allows for faster charging/higher charge rate.
Using the computer will only "trickle" charge. Using a USB 2.0 cable with the TF setup will prevent it from charging or only "trickle" charge....
I did not use any other cable or outlet device beside the one that came with the TF.
It seems it only syncs, but it does NOT charge !!!
I took it to Best Buy they said we can refund the money to your credit or choose another tablet because they don't have it in stock.
I don't want another tablet. If I had to, I will go to iPad 2
3 days now and I am having no issues at all.
I called ASUS, and they said its from the adapter, and I can not use any USB adapter like apple's. So, they want me to send it back to them, and they will do diagnostic at everything and will return it to me.
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:

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.
I just received an Aukey USB cable 2m in length from amazon after reading many positive reviews. For some reason when i plug in(Samsung Note 2 and Sony 1.5A adapter), the charging bolt comes for about 2seconds(measured 1900ma) and goes off. I keep it aside for about another 2~3mins, the charge bolt comes(for 2s) and goes off again - this goes on a loop. I tried connecting to another AC adapter(Sony 2A CP-AD2) with the Aukey cable, but experience the same issue. I tried connecting it with my brothers phone(being a Samsung Note 3), the charge bolt does show up(measuring 1800ma) but the charge level drained from 4% to 1% while using for about 5mins while plugged(like as though it wasn't plugged in).
Now comes the weirder part, i connect my Note2 with the same cable to my macbook, to my surprise the phone does charge(460ma) as well as data transfer too is possible. The charging is true this time because i didnt notice a drop in percentage. This has left me very confused on where the problem lies. Has this occurred to anyone?
ps. i have seen people on the comments say the cable works perfectly with an Aukey Charger. I dont suppose a sony charger would interfere with a third party cable

Hello,
Guyz can you tell me why i am getting like 30%Battery in 8h of charging?
My Tablet is like 4 years old im using the gnabo Rom with its standart kernel.
But sometimes it charges normaly?
Does anyone have an Idea?
Usual .
Battery on its way out .
USB cable or port faulty .
Charger faulty .
I Did a research. And i turned off my WiFi while charging and it charges normally now!
Through trial and error, I have found a way to speed up charging and use tablet at same time by purchasing a 2 amp charger, new generic Samsung n8000/n8010/n8103 usb long cable, more importantly a pisen for galaxy usb converter. Also, this converter is useful for charging with external battery pack.
All items are available on eBay or Amazon.
hi all,
I'd like to submit you a strange behaviour of my beloved nexus 5.
Suddenly, with every charger and cable I can merely reach 200 mAh, very slow charging that actually doesn't allow the phone to charge up. On the other hand, wireless charging works quite well, at least i can recharge the battery.
What do you think? could it be related to the flex cable/bad usb port? USB otg works....
on the other hand, could it be a motherboard related problem? (but in that case, why does wireless charging work?)
thanks for your ideas guys!
