Stupid thing stopped charging :(

So, I'm traveling (for a long period of time) with my TF. One day, it stopped charging.
I took apart the power brick and put it back together, I even tried to freeze it (on advice from some older "not charging" threads), nothing helps.
When I connect the TF to my laptop via USB - it recognizes the TF. When I connect my iPod to the power brick (with its own cable obviously) - it charges just fine. So what broke?!
I hate this, the local stores here don't sell the power brick separately and I don't even know if that's the source of the problem.
This sucks

Sounds like the power pin in the TF port has bent/broken or just has some detritus/dirt/foreign matter in it and is stopping it from charging properly. Have a look, but you might need to check the port with lots of light and a magnifying glass, so not easy while you're on the move.

If you are in the US Office Depot sells the charger and USB cable for $30.

strange thing is that sometime my transformer doesn't charge.
i have to reboot and it start to charge again.

Same happened here. Asus tech wanted me to wipe the device. After trying other options to get it to charge, I did but it didn't wipe... Go figure... But it booted up normally and now it has been charging.

Apparently charging has some history of issues on the TF101.
I just had mine act up on me, went around the house trying different wall sockets and checked that it worked fine via USB to PC. Ended up taking a can of dust-off to all the pins, then shoving the plug hard into the TF101 socket. Now it works.

Should have mentioned I have a dock as well, which doesn't charge either (so problem is probably with cable/brick)
I'm trying to get new ones (nowhere to be found here, but I'm trying to get one sent to me). I tried looking for dust/dirt and different wall sockets, no luck.
Weird thing - I left it plugged in to the wall overnight and it grew from 5% to 15%, so looks like some electricity is trickling.

I had the same problem with mine after I had it for 5 weeks, I just RMA'd it and everything is fine.

Im having the same exact problem. I left it charging over night by mistake the night before yesterday. I only let it charge 3 hours the most because I know the Transformers have known issues.
I tried to charge it this morning and nothing. I plug it into my PC. The PC recognized the Transformer but no charging. Turned it on and off, nothing.
Just put the power brick in the freezer, waiting to dry up to see if it works .

Although the tf charger and cable has a usb connector it is not usb compliant. the charger brick looks for a gnd signal on pin 7 of the usb connector ( normally a usb 3.0 data line) to determine it should supply 15V to the positive charge pin vs standard 5V. The slow charge you are seeing is from the 5V supply . check to see if pin7 is seeing the gnd signal. Are you using a usb 2.0 extension cable as it doesn't have have pin 7 conductor. be careful connecting your ipod as it could accidentaly see 15V vs the 5V it is designed for.

Transformer does not charge anymore

First of all: Yes, I did use the search function. Yes, I did use google. But No, I did not find an answer to my problem.
Hopefully you guys can help me:
I bought a TF101 a week ago - it is used and came without the charger nor a data-cable.
So I bought an datacable off amazon which worked fine. But as we all know a usb port has not enough power to charge the tablet.
After looking around the Internet I build myself an molex to usb adapter which worked like a charm.
But now I plugged in the cable and it's not charging anymore. (8h ago it worked fine)
The cable is fine (PC can still connect to the transformer).
The adapter is fine (multimeter is giving out 11.56V)
Now when I plug in the cable it gives me a picture of a nearly empty battery.
I tried resetting the tablet - no effect.
Anyone knows this problem? Or has an idea how to fix it?
Transformer details:
TF101-1B032A
Android 4.0.3
Kernel 2.6.39.4 [email protected] #1
Build number: IML74K.WW_epad-9.2.1.24-20120503

I think you should first bought the Asus original charger instead which guaranteed supplying 100% correct voltages and ampere to your tablet. Does it charge via PC USB port now?

11.56V isn't enough to trip the HV charge, you need at Least 12V.
Try the ASUS charger.

And the only way to confirmed this is by plugging the TF to PC via USB port and see if it still charging, or try the original Asus charger.
Using another adaptor with rating voltage safe to our TF doesn't guarantee it fit to the TF after all. There's always fluctuation in between the incoming and outgoing supply, and the transformer seemed to be a little sensitive to this tiny changes..

The cable could be faulty.
Mines was - and yes the pc still recognised the tablet when connected. Theres 4 pins in it compare to the usual 3 (i may stand corrected on that 1)
RMA confirmed this and Asus sent a new sync cable back.
Its maybe going to cost a few quid but as the rest of the guys have said - get an origional charger and cable.

Ok, first of all thank you for your help.
I would have bought a original Charger but could not find any in local stores nor amazon (.de) exept a traveller set which costs around 40€ (which is too way much)
I plugged the transformer (turned off) in my IPod wallcharger (5V1A) overnight and it charged.
Now I am really confused - why is it charging over the lower voltage output but not over the 12V?
//Edit:
Thanks to (the) Thing o Doom
I tried pluging the adapter to another powersource and it works. (I feel stupid to not tried this earlier) Seems like my mobile molex power supply is not fully working.

It's the build in power protection preventing your TF from catching fire from over fluctuation voltages supply. In ASUS original charger, it maintain the right amount of output even with uneven input supply. And the ipod charger has it as well..

[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.

Asus TF101 cannot charge

Hi all,
I owned the Asus TF101 for more than 1 year (warranty expired).
And now my pad cannot charge anymore. I sent to the service, and they talked that mainboard need to be replaced :crying:
But, it still works fine, just cannot charge. I think the charger is broken and bought a chinese charger, but it can only charge a little (20-30%), then stop charging.
Do you think the mainboard is dead? I can believe i that.
Does anyone have this problem and how to fix?
Thanks.

You say you bought a Chinese charger, if by this you mean you bought at USB charger, it will work but very slow and only with tablet off. The TF101 needs 15V on the charge pin to work and the stock charger provides that when pin 7 is grounded by the tab. When pin 7 is not grounded, it provides standard 5V and will not charge well. Try several things. Put stock charger in plastic bag then in freezer for a few hours in case you tripped the over current protection. Take it out and let it warm up in bag then try charging. If that does not work, you can try get a Dynex video camera charger. It has various levels of output voltage on a usb connector. Set voltage top 11V and you should be OK. The TF uses a physical USB connector, HOWEVER the voltages in the connector as well as other signals ARE NOT USB compliant. This means a standard USB charger WILL NOT WORK.

No, I bought a charger like this:
http://www.amazon.com/POWER-ADAPTER-TRAVEL-CHARGER-TRANSFORMER/dp/B007LI1UOE/ref=sr_1_1?ie=UTF8&qid=1351734650&sr=8-1&keywords=asus+transformer+charger
Output: 15V, 1200mA
But, at the first time, my pad can charge up to 50% and then stop (not charge when shutdown also)
And now, it will not charge anymore, when I plug the charger, it's only charged 1 or 2 minutes and then stop.
I tried put the original charger to the freezer many time, but not fixed.

Try a factory data reset in the Android settings menu. If that doesn't work, see if you're power adapter can be taken apart (most can to handle international plugs). If so, clean all the metal points where the wall plug contacts the power transformer.

I had the same problem and found a solution:
It's not the cable, but the 2 pins inside the USB opening at the charger!
If you look inside at the top you will find two pins that suppose to fit in the two holes from the USB connector.
By pulling them in and out, these pins move up slowly until they dont fit in the holes anymore.
Grab a little screwdriver and move the pins a little bit back out by sticking the screwdriver behind them.
Reattach the USB cable...you'll be surprised!

A buddy @work bought a used TF101 so cheap ($179, B60 a few months back from Cowboom). It came looking great but just won't charge (is it why it was cheap ?). We tried the freezer trick, that didn't work. The cable was fine hooking up to the PC and would charge slowly from there ----> Finally the cause: it's the cable itself. I gave the man my spare cable (bought @amazon, 2 for $5).

Hic,
I borrow a new charger from my friend, and still not work. I tried reset many time, but nothing happened.
I think there is problem with the main or the charge port connector.....
Maybe I will try to open it. Mainboard replacement take about 200$ (from ASUS service), and I think buy a new one is better. Say goodbye to ASUS.

For greater clarity it's the two outside pins on the row of 4

Does not work for me - also the freezer thing...
My problem is irritating: Yesterday the Charger did not work at all. Then after many attempts to fix it (like freezer,...) I just put it into an Apple wallcharger - did not work either but then I used the Asus Charger and it worked.
Now it does not work - one more time...
Any suggestions?

The reason other chargers (like Apple) do not work is that they only output 5 VDC. The Asus wall wart outputs 15 VDC when an Eee Pad is detected, otherwise it puts out 5 VDC.
It could be a bad cord that one of the contacts is loose and it sometimes does not detect the Eee Pad.

Yes, I noticed that too. I put it in a Apple Charger (is it normal that there is no charging remark on the display?) but then after doing this my Asus charger worked - for 5 hours
I am confused...

I have a new problem, my dock doesn't charge. It show the battery with 0 charge but when I connect the charger. It only charge up the tablet. Dock will remain at 0 charge. Any suggestions? I have try fully wipe & reinstall other rom but still having the same problem.

Many users who have let their dock get to 0% have had this issue. There is a toggle switch in the dock that changes state when you get to 0% and does not always switch back when you charge it again. You can try opening the dock and changing the state of this switch and then it should charge after that.
Why it was designed this way, I have no idea.

There's also a user that reported a "known bug" about it here, saying he was going to RMA it. Supposedly some docks are missing a part to make allow recharge at 0%. I can't confirm or deny it.

I'm having the same problem with my charger right now, it will only trickle charge from the ASUS provided adapter while the unit is off, and when the unit is on, it recognizes that it's plugged in to the charger, but does not charge for some strange reason. Is there a possibility that this is a hardware problem within the tablet? or is this a charger related problem?

Gonna answer this in a few days.
As you can see up on the page Ive got this ***** issue. I bought a new original asus charger for around 35 bucks, it will come the next days. Then I can tell you whether it is a problem with the charger - or not.
A fix which worked for me (for about 75%):
Connect the TF to a Apple wallcharger (so it should charge - doesnt do it at all - everythings good). Wait like 10 minutes then you can reconnect it to the Asus charger. If this doesnt help: Strech the cable a bit while "charging".

I had the same issue when I bought my "charge cable" come to find out it didn't work because it was more of a sync so it would mainly sync to PC or device it was connected to then I leave it plugged in over 24hrs and maybe get about 52% of charge ... I bought a charger from Amazon works like a charm and really cheap
This one I bought for tf101 works like a champ

I've heard that it's better to NOT buy this charger because the voltage makes the touch digitizer screwy, and can cause battery damage in the long run.

Asus TF301 - charging problems
clicky007 - I just wanted to say a BIG THANK YOU - I 'tweeked' the contacts and my ASUS is charging again. Just as back ground, I had always used the ASUS charger and cable together. I have only unplugged the USB connector a few times, as few as 6 (guess-timation). Not exactly a high level of uses/insertions. Poor quality Asus!
Anyway - Many thanks to Clicky007 and Forum-xda

surprisingly enough this fixed my charging problem as well. At first I couldn't identify these two pins that you mentioned but for anyone else having the same issue I had. looking at the charging port on the TF with touchscreen facing up and back of the TF down the pin is not on the middle bar with the multiple connectors but it's it's attach to the top part of the port as illustrated by the tilda in my badly drawn diagram below and dashes representing the middle connector bar

TF300T stays at 1% & will not charge

I recently picked up a used TF300T with a shattered digitizer. I managed to successfully remove/replace it & the tablet is working fine.. except for charging. It turns on and says the battery is at 1% and needs to be charged. When I plug it in to charge it, it doesn't charge(just stays at 1%).
It came with a genuine Asus USB cable & what appears to be a generic USB wall charger. When I connect the tablet though, it registers and the screen comes on. When I plug it into my PC it also comes on and registers(so I know the USB cable and charging port on the tablet are fine).
I do have other tablets(iPad 3, iPad Air, Surface Pro 2, etc..) and tried using the wall chargers that came with those, but still no luck.
I'm assuming then that I have to use an actual Asus wall charger meant specifically for the TF300T? Or do you guys have a link to one that will work?
EDIT: -- Ok, I just tried another generic that I have here. It's a 5V 2.1A and the tablet is actually charging... oddly though, it doesn't show the charging icon nor does it say it's charging... but it is.

You need a 15 volts adapter not 5 volts!

The weird thing is, the Surface Pro charger I have is 24... and it charges just as fast as the 5 I used last night. I borrowed an Asus brand charger today and had no problems at all with that.
