[Q] Can't charge, won't charge

Plugged in Transformer last night to charge it up overnight when the battery hit 30%. I updated the firmware yesterday morning and everything was going swimmingly.
Woke it up this morning, and found it was at 9% battery remaining and had a low battery warning. I had a closer look and the battery icon shows no indication that it's charging when it's plugged in.
Right now I've plugged it into a bog-standard USB charger and turned it off, hoping it'll trickle charge (damn the lack of a charge LED!) and that it's a fault with the power adapter rather than the device itself.
Anyone else had this issue?

I had the same problem a few days ago, my charger was plugged in via a multi block and it would not charge.
I even went to the extreme of taking my device back to comet in the hope I could swap the charger out with their demo unit.
Man behind counter plugs my charger into some sort electrical surge protected socket and it starts charging straight away leaving me looking like a right tool standing their. (and they tried to sell me 3 years extended cover)
Brought it home and plugged it into the very socket where it wasn't working and what do you know? It starts working!
Not sure what the issue was but it now works again.

Ok well that's good to know!
On trickle-charge it's now gone up by 2% since I posted.
Looks like the power adapter has its own faults...

Oh, and what do you know... plugged wall charger back in (it's been unplugged for 20mins) and now it's all happy and charging again.
Hooray.

yeah maybe that 20 minute trip to comet fixed mine too..

the USB mains adapter plug has a fatal flaw - the middle part of the usb connection isn't as sturdy as it sould be so it is easy to plug a USB port in the wrong way around and it looks and feels plugged in correctly as the middle part just moves out of the way.
If it isn't charing always check to make sure the USB connection is in the right way around in the plug.

I am bummed about this proprietary power connector; and apparently proprietary USB cable with extra pins (negating the use of USB extension cables). I wish the TF had a standard round power adapter similar to the Acer A500.

Thank God, i thought i was the only one. Had exactly this problem with mine when it arrived a couple of days ago, i am lucky enough to have lots of USB chargers around so i tried and tested various combinations and tried to charge other devices with the asus charger.
The problem lies as far as i can see, entirely with the charger unit. The charger comes in two parts, one is the usb dock and the other the relevant country plug. The way the plug fits onto the face of the charger is the important part. There is a central 'locating pin' made from plastic and two contacts that slot into the charger carrying the live and negative. The construction of this part is very, very poor. The tolerances are not a match for the quality of the plastic, the T shaped plastic locater does not actually locate the bottom pins properly and needs a great deal of force to lock in placce, and here is the best part, it doesnt like STAYING locked. As the plastic is weak, and we are looking at just a couple of mm here, it will snap, that will stop there being a clean contact and no charge. As a remedy, i have secured the face plate to the charger very tightly with a high tech rubber band
I agree, the use of specific power connectors in this day and age is just as dumb a decision as any manufacturer can make, and the rate it recharges at from a USB to PC connection can only be described as comical, a full recharge in 26 hours . Aside from all that its nigh on perfect, but i can see power related alternatives being VERY popular until Asus catches up with the rest of the electronics industry.

havent even had mine an hour and i havent done the update because its not at 50% and it will not charg at all. when i first tried to start it i thought it was doa because it would not turn on. guess ill take you guys advice and leave it unplugged for a while. i hate the charging cable is so small too that definately sucks.

Hmmm... if only a few other people created topics about not charging...

[Q] Wall Charger dead after plugging in USB 3.0 cable

A word of warning - I received my USB 3.0 extension cable from Amazon yesterday, plugged it in when I got home and it started to charge. I noticed after a few minutes that the charge icon had disappeared and now the charger does not seem to work at all; tried both dock and tablet sockets.
This was the cable recommended from the other thread on the forum about charging the device.
http://www.amazon.co.uk/gp/product/B003QZKMU4/ref=oss_product
I'm fairly sure that it is the UK three pin socket part that has died as the machine is picked up by my PC over the USB cable. I've tried the usual taking the thing apart and re-clipping it back together, I've even checked the teeth on the cable to make sure nothing is damaged, still no joy.
I've emailed Asus support but after reading through the forum I'm not overly positive that they will be any help at all. I suppose I'll have to wait for the Chinese/Hong Kong factories to start kicking these out on Ebay as there doesn't seem anything in the UK at the moment. So I'll sit here and watch my 90% battery slowly die and the machine get covered in dust.

Why don't you get a cheap ipad charger in the meantime. Takes longer but do the charging overnight?

Thanks for the tip. Is the propriety charger the same or do you just mean the USB wall plug end?

My PSU died, and after a week of back and forth to ASUS service they have declared my TF DOA and told Comet to replace it.
They are doing a doorstep swap tomorrow for me.
I have also posted about PSU's with a known fault, look in the accessories forum

I had the same issue. For me i fixed my PSU by unplugging everything for 20 minutes. Sounds silly but it works. Unplug from the wall socket, take the usb out of the PSU and the TF and leave it al alone for 20 minutes.

I checked my serial number a few days ago and it was supposed to be one of the ok ones.
I also took the thing to pieces as much as I could without resorting to a screwdriver. It's been left out over night and put back together a few times.
The whole thing doesn't look to be the best put together electrical item I've seen. In fact my Desire charger makes it look like some 5p Chinese shonk, oh err hang on a minute it is.
Just looking at iPad chargers now.

Same thing with me and extension off ebay one day after I got it. What I had to do was a factory reset to get it to show the charge icon. Now it's been fine since going on 2 weeks now.

Funny you should say that, I was all about to give up and then gave it the tap of life on the window ledge and it started working again. The annoying part was that I'd moved it from the usual changing point to test it out so I have had to very gingerly move it back.
It's still working but I'm not sure how long it will last. I think that maybe the USB lead must have move something out, which is odd as it was a really loose light connection. The upshot is the charger is now going to be left untouched and the USB 3.0 lead is going in the bin.
Not really a robust item the wall charger!

Yes, mine was one of the good ones too....

I second this.....same has happened several times to me when trying to get usb 3 cable to act as charger lead extension. Just leave it unplugged for 15- 20 mins and all ok.

Charger or dock battery??
I don't know the inner-workings between the charging adapter, the USB cable and pins - and the dock battery itself so I thought I'd throw this out there:
My dock battery has stopped charging. I can plug the tablet into the dock - have the dock plugged into the wall - and the tablet itself will charge (and the adapter will heat up) - but as soon as I remove the tablet, the adapter cools down, and the dock battery never charges (just blinks orange forever).
I've just been assuming all along that it was the dock or the dock battery that had gone bad for some reason.
But would it be possible that it could be a pin / cable / adapter issue instead?
I wonder if different pins control the charging of the tablet vs the charging of the dock?
I'm *hoping* it's the dock itself because at least I can still return that and wait for another to come in stock. But if it's the adapter or cable, it looks like I'd be SOL and have to send my whole freakin tablet back for a replacement!

I'm sitting on hold with Asus now because last night neither my tablet or dock would charge. I do not have the extension cable but have one on order from Ebay. I was planning to test all the pins on the cable while the unit was charging to figure out which additional pins are communicating with the charger to start the charge. While sitting on hold I came across this post and decided to try the charger again and now my tablet is charging. Will try the dock once I'm fully charged.
I love my TF but this charging stuff is micky mouse. I hear some people can charge connected to a PC, I have never been able to. Now I need to do some more searching to see who had what extension cable from where.
Check the thread link in my signature to see my finding for making a cable to allow charging from other sources.

It's all a bit of pot luck by the sounds of it.
Don't leave it on charge over night, don't plug the wrong sort of USB lead in and don't move the charger.
I think I'll be buying some £2 Ebay charger as soon as they appear, can't be any worse.

A sense of panic set in when my charger stopped working after trying to use a USB 3.0 extension cable I purchased from Monoprice. After following this simple suggestion, I'm happy to report that all is working once again.
I never did get the USB 3.0 extension cable to work though. It was one that others have reported success with too. I guess I'll be sticking to a cheap extension cord for now.

This extension from CompUSA works like a charm. Its prices is awesome too. The adapter charges TF/KB seamlessly for me. Spread the words.

Ultra also makes this cable in a 12 foot length. Part #U12-40579. I have both the 6 foot and 12 foot lengths and they charge my 32TF and dock without issues.Both can be purchased from CompUSA.

[Q] Broken Micro USB Port

Okay so my usb port has been a bit annoying the past week - where i had to vigorously wiggle the cable to get it to charge or to sync (and even when it did decide to connect to the computer, it would chop out eventually)
But now it's no longer charging or being recognized by my comp
It's strange because the headphone adapter was working fine, and so was the usb host, but it just wont charge anymore - I effectively now have a dead TG01
Currently, i'll get the orange light, telling me it's charging, but when i try to power on, nothing happens...
So i'm thinking a new USB port which is where I need some help: I'm not sure on what part to get
But maybe This is the one? Comparing the images with the ones found on the net of the TG01 (Yep - I still haven't got mine open yet)
But yeah, just a heads up on whether you think it would work would be epic, or whether you think i should just try a different battery/charger/throw it away (Although i'm almost certain it's the port, as it was working intermitently before - it's now gone altogether)

are u using only usb to charging or an wall charger?

Wall charger, but i tried USB, and still no luck
It just wont charge at all, regardless of the orange light when plugged in now that it's off (though i wouldn't get it when the phone did still have charge left and was therefore still switched on...)

BUMP: Any ideas you clever people? Just some guidance would be nice...
I'm still without my beloved TG01, I'm having to use a **** old Samsung G600

I do have some problems of my own with my USB cable. I believe the problems are due to the cable, though. The wall charger works fine. The USB cable that I use, has to stay somehow "forced"... imagine having the cell laying face up on a desk. The USB cable gets out and is forced by a small pen that stays right near the cellphone, to have a 30% slope upwards, so pushing a bit the cable onto the upper part of the USB port. I do know that you are telling us a different issue, however, maybe this way you could check whether it's just a broken connection and not a completely dead port.

No, this sounds like the exact issue i had...
It was like this with the Charger and USB - where i had to force it to be recognised or charged, and it would still cut out after a while - and wiggling it or knocking it wouldn't actually affect it, it would be of it's own accordance...
But it was strange because the headphone adapter worked fine...
Nothing happens at all now though

Are you try: Settings- Connections- USB to PC- unmark Enable advanced network functionality

I can't turn the phone on because it wont charge, so it's not that

Battery may be defective. Try with any 5V charger, connect directly to battery pin in 10 min

Hi
It vaguely remembers me of something I read on the forum about different micro usb (explaining my different cables do not connect just the same, some easy, some bit forced); I think there also was a drawing. (but I don't have time to search for the exact thread; it was not the "solving usb port mistery one))
Maybe your earphone adaptator don't have exactly the same as your charger? And if it is not battery trouble, find a charger with the "very right" micro usb plug?

Thank you both so much for your response:
I understand why you say it could be the battery problem with the charger - but it doesn't explain the intermittent connection with my computer when using the USB cable. Which is convincing myslef more and more that it's a port problem
One solution for now would be to buy one of these cheap external battery chargers from eBay, but it would mean i still wouldn't be able to use sync using the USB cable and i'm a bit conscious on whether the charger is safe and wont fry my battery
Which is why i'm leaning towards having a stab at reparing it myself
It'd solve the issue directly and it'd be a safer and more secure solution too... (the external charger would have to be ordered in from Hong Kong eBay)

I'm having what seem to be exactly the same problems. I have used 2 x usb based chargers on it - and neither work (whereas they had been working for the past 6 months). Got a mains charger last week - was working for a while - but as of right now, no longer works.
I'm not sure what else to do. I will try later to use the other adapter I have for connection to usb keyboard. The strange thing is - this will probably work but charging won't!
So....is it the micro usb port that's broken? (strange if it is but still works for data)
OR
could it be the battery?

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.

Very strange charging problem!

Ok, first a little background on this issue...
After having my S3 for about 13-14 months I started having charging issues. The charging port was very "loose" and I had to make sure my charger cable was in just right to get my phone to charge. This was annoying, however was out of warranty and didn't want to pay vzw for an insurance claim. This got worse, and eventually I noticed my phone would only charge with 1 specific usb cable, 1 specific wall charger, and 1 specific car charger.
Well, I finally called Samsung and explained the situation to them and they had me chip my phone to them and they would repair it, free of charge. When they had it, they replaced the charging port, the headphone jack, and the screen. I received the phone back after couple weeks, super excited, and immediately charged it up with the cable I had next to my bed. New charging port felt perfect, nice snug fit, etc... Well, after a few days i hooked it up with the original usb cable that came with the phone, nothing happened. So i started messing around and realized that the only usb cables that will charge my phone are Motorola brand cables! At least the 2 cables I have work, and not a single other cable I've tried works! This includes stock Samsung cable, many cheap 3rd party cables, other friend's S3 cables, none work. Also, I have this cheap car charger that is the type you plug a USB cable into that works, however any other car charger I've tried does not work either.
Also, when i say the cables won't charge my phone, it also won't connect the phone to a PC. They do absolutely nothing.
Does anyone have ANY idea why this is happening?!?! It was an issue before Samsung repaired my phone, they replaced the charging port, but I still have this issue!! I can send it back to Samsung for them to look at it again, however my backup phone, a Razr Maxx, just died also. Seems like the battery went dead and now I can't get it to charge, but that's another issue.
So, any ideas?!

What rom/kernal

It doesn't matter. It does this when it is totally stock and rooted. Right now I'm not rooted or anything because it looks like it may be going back to Samsung again.

I think the smart charging circuit may be messed up

Really? How would that cause the phone to not work with any cable except a certain brand?? I'm just really curious and this is driving me insane!!

I would say you are putting mechanical stress on the charging port. This could be from some misaligned or mis-made cable or somehow pressing or pulling the charge cable when its connected. I've never seen this reported by anyone else, but the mechanical connections are not indestructible. If it were a common symptom with 100 million S3s having been sold, there would be a firestorm of complaints.

I have a similar issue. I'm not sure if it's the device or the ROM (CM nightlies).
Certain cables force the screen to turn back on, which means I get negative charge because the screen burns more than the charger is capable of supplying. Other cables are fine. I'm still looking for the pattern, it's super annoying and causes me to have to turn my phone off completely at times so as not to lose my battery altogether. I'm still trying to solve this, any help would be appreciated.

Further info- it's not the cable, it's the converter at the end. I think it has to do with amperage of the charger- if I use the stock samsung one I'm good, it's putting out 1.0A. If I use others that are fewer amps (like 700 mA) it's unpredictable. I suspect a kernel thing, I might download different kernels to play with it.

Always use chargers that is 1 A - 2A the circuit controls most of the charging regulating amps and voltage

Yes, I agree about using good chargers, but my phone wasn't always this way. It used to charge with anything, but no longer.
I enabled fast charge on Imosyen's lean kernel. That might have made a difference, but I'm not positive yet.
