[Q] Charging problem agin, powered on just with charger - Eee Pad Transformer Q&A, Help & Troubleshooting

Well my TF101 stopped working and i realized that battery was gone, no any voltage on red and black pins.
After changing battery (e-bay ordered) TF got powered only with charger connected and goes off if i remove charger, but it does NOT charging at all.
Not powering, charging and detecting on PC USB port too.
what i have done?
1. checked lines on cable - all OK
2. Checked wall charger - working - gives 15V to the socket inside TF (even checked for 15v inside TF , there is a flex cable and it is working). It gives 15V to the main board - but not charging
3. Freezed wall charger - no charging yet.
4. There is 7,4v on battery red and black pins (have to be more if charger working)
5. can not find schematics for TF101
could be battery defective? i think no, there is 13% showing in battery stats.
Could some experienced service technician in ASUS give me some advice.

At least yours shows up something .. I'll have to check my black and red ... I can't get it to charge at all ( I think it's fully dead ).

At this point RMA it if you can, as there isn't an easy way to diagnose the problem.

Could someone sent or upload it?

[Q] TF101G - Charging issues

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.

[Q] Tablet and Dock not charging - cable is OK _ Wall charger fail [Solved]

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?

I sent email to Asus on Friday and waiting for response.

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.
Sent from my GT-I9000 using Tapatalk 2
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...

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

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.

Worked like a charm!
Sometimes the problem is less complicated than you might think
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

As it's stated above - The Galaxy Note 10.1 can not charge threw USB due to the high power usage, all it can do is a "status quo" on battery usage.
So if you wan't to charge the Note, plugg it directly into the wall, and if possible, avoid power extenders.

If you are using the ac charger and the original cable, then you may have a fault in either the charger or the usb cable
If you can borrow a friends usb cable test to see if that helps
If not try your friends charger.
After a while the usb cable gets damaged and when damage can show a fault in different ways
Slow charging
The red cross appears
It shows charging but the battery never goes pass say about 1%
It shows charging but instead the unit is discharging.
If you get any of these before you wipe your device try another cable if possible
I have had my replaced already and ferl I will go and get a docking unit, and a spare cable

sorry for late reply.
i did get a new charger from ebay but unfortuately the red cross is still there but nevertheless it charge slowly.. it took me about 8 to 10 hr for fully charged.
any other solution?
The probabilities are:
Charging Port is broken
Charging cable / Charging cable connector(s) is(are) broken
AC Charger is broken
Analysis:
Borrow someone else's charger & cable
Try the combination :
Other charger + your cable ==> if working then your Charger is broken
Your charger + other cable ==> if working then your Cable is broken
Other Charger + other Cable ==> if working Both Charger & Cable are broken
If all failed ==> your Charging port are broken
Eliminate posibilities

Battery dock replaced but still no charging!

I've successfully replaced the battery of the dock with a new one. It was showing some charge 36% instead of 0% and no more tablet draining, but it never charged! So now it's at 9%, red dot blinking, and I don't know how to fix it! Charging sign appears when plugged in and tablet charges trough the dock.
I've tried the cold boot and the trickle charge but I didn't see changes, maybe I've done something wrong?
What more can I do to make it charge again?
I thought it was the charger or the cable but for what I see the 40-pin connector has actually only the 4 pins (the usb signal) so I don't think I need another cable.

I don't believe it is a software issue. It might be a contact issue caused by yourself I think.
Firstly disconnect your tablet from the dock. Connect it with the charger and check if it is going to be charged. If so, your both charger and cable are OK.
Secondly check whether all contacts between the battery and the dock are closed correctly or not. Please follow backwards the sequence you used to taking out the old battery by yourself.
try and charge it with the official charging brick, or at least something that can put out 15V at 1.5A i had the same problem when using my tablet after a long time and only my tablet would get charged not the dock
Yes I'm charging it with the official charger, maybe it got some problems
I don't have a tester at the moment but I got a doubt. Is it possibile that the cable has 2 charging lines one for the tablet and one for the dock? Because I want to buy another charger but maybe it could be not compatible for charging also the dock.
I opened it again last weekend and there was nothing unplugged, everything was good.
