Hey Everyone,
I have myself the Nexus S and at one time I could charge the device without it being powered on, obviously for a faster charge.. But as of now the phone boots itself on once the charger is plugged in. Has anyone seen this, or had this issue?
weird, no, i have not seen that issue
which ROM are you running?
i can power off the phone, and charge, and see the WHITE charging battery icon with the white bars
Ok,this is strange. I just pulled the battery and tried a different charger and now the device works as it did previously, which is allowing me to charge without the device being turned on. Is this am issue I should be worried about or just a minor glitch?
I'm not running any custom ROM. The phone is completely STOCK. That's why I was a little puzzled
The chargers I'm using are different though. One is a straight ACDC micro charger,and the other is a charger that uses a USD to connect to a charging module.
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?

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.

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
Running Cleanrom 5.0 with Imoseyon Kernel. I enabled USB fast charging, at some point I plugged in my external HHD to the phone and guessing that fast charge was still enabled, the phone shut off right when I connected the hard drive. Now it wont boot. Tried different charger, battery and so on. Anyone heard of this happening before? Maybe a fix?
I bought a stock samsung battery for my galaxy s3. I am trying to charge it but it is not moving forward at all. I've powered off the phone, plugged in the battery and then plugged in a usb cord to charge it.
The results are the same no matter where I charge it.
I've tried two different AC adaptors and a usb cord to the computer.
When I plug in the power source, the phone vibrates once, shows the galaxy s3 logo, displays a battery charging status showing 0% charged. The battery is filling up green indicating that it's charging. It will perform the animation of filling the battery twice then the screen goes blank.
I've left it plugged in for a while now but it doesn't seem the be actually charging. I cannot turn the phone on with it plugged into a power source or not.
If I put the old battery back in, everything is fine.
I'm running the latest cyanogenmod m4 release.
The new battery you got is obviously a dud. Replace it

I am longer able to charge my phone properly using a wall charger... It only takes 100ma current when plugged to an Ac source..
It charges properly when connected to a USB port..
I was running on cm 12 + Boeffla kernel when I first had this problem..
Tried wipe/data cache and now flashed stock 4.3.
Still no use it takes around 1 hours to get 2% charge on Ac.
Ps. Battery is working properly got about 1 day backup. ​Anyone please help me with this asap
Charger defect? Cable defect?
Usb Plug dirty or dusty?
Tried another wall charger?
Andi
Tried 3 different chargers but no hope
But I've found a temporary solution by enabling ignore unstable power and safety margin in Boeffla kernel config app.
It seems to be working... Thanks to Boeffla kernel for saving my phone.
