[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] TF101 NOT charging

Is anyone else having an issue with charging? it worked fine for a week or more. now when i plug it in, to any outlet, it wont charge at all.. they are considering RMAing the entire unit, and im going to be torked off if i have to wait weeks to get another. argh.
just curious if anyone else is having charging issues.
thanks

My unit doesn't charge if the battery is above 90%. I see no problems there, what % is your battery at? That is expected behaviour to an extent to prevent overcharging of the battery.
Sent from my Transformer TF101 using XDA Premium App

Mine did that once and I just left it alone for awhile and it started to work again on its own.

i only noticed it because its asking me to connect to charger now.
so its at 11% right now.
Tech wanted me to trickle charge to see if i get anything out of it. Its not working.
Is there any lights on the adapter? i cant remember? but i think the unit may be bad.
SOOOOO pissed, now i have to wait weeks for a replacement to show up.
Has anyone else had a unit they have had to RMA??? is so, did they send a brand new one, sealed in box? if so, i have an extra here, ill just use it and sell the RMA one when it comes in.
thanks
EDIT: i had it trickle charging in the off position. just turned it back on. then plugged it in to wall. seems to be charging now.. WTH. wonder if its something with the dock?

Thanks
Hi
Nice to have found your thread on this - mine was doing the same thing after I had if docked. Connected it to my PC and synced and then put it back in the charger and everything is fine.
Weird.

Since you guys seem new to this forum, I suggest you read the stickies. The "Ultimate Transformer Information Thread" mentions some specific adapter issues you should be aware of.

TF101 not charging after run flat issue - SOLVED
Hello
I also had this problem. The tablet drained the docking station dry, and then neither device would charge from the adapter.
I solved the problem as follows:
1) Remove table from docking station.
2) Turn tablet off completely.
3) Plug tablet only into the charger, at this point the tablet turned on, and began charging.
4) Allow the tablet to charge completely!
5) Reconnect tablet to docking station, and plug docking station into charger.
Voila, all charged Hope it works for others who have this issue!

Mine also had charging problems. When I charged it, it never reached 100%. I took it to the Asus repair center, and they called me today and said they got it to reach 100%. Also, above 90% it reports the battery status as full.
I also to them about the battery drain problem, and gave them my tablet with the dual battery widget installed. Told them to charge both the tablet and keyboard to full, dock the tablet, power off, and wait until morning to see the results.
I'll find out what happens tomorrow when I go see them in the morning.

TF101 not charging today...
It happened already once some time ago, but leaving the power adapter disconnected from the wall plug for 10min solved the problem.
Now it's happening again... and previous workaround is not working.
Tablet is TF101, no docking keyboard, last version of ICS installed.
I've checked the various threads for suggestions: of course I tried the various reboot options; the only thing I'm missing is the refrigerator, but the power adapter is cold (tablet is not charging since 2d, and battery is still alive...).
I've not checked the cable, but have cleaned with air the connectors (just to avoid dust inside).
Any suggestion is welcome.
Thanks

I have had my charger stop working twice in the past 6 months. Both times I put the wall adapter in a zip-lock bag and placed in my freezer for 30 minutes. Upon removing I plugged the usb cable back into the adapter and bam, everything was working fine again. From what I remember, there is a temperature sensitive circuit breaker inside the adapter that sometimes gets stuck. Even if the charger is cold or has been left alone it takes the dramatic temperature of the freezer to unsieze it. Good Luck it worked for me, twice.

Power plug charging sometimes

I have a power plug and sometimes charges and sometimes don't. It also gets hot after about 10mins of charge but it is charging.
I know there has been a few faults but has anyone experienced this charging sometimes and hot to the touch?

The charger getting hot is a good sign; that shows that it is working. The charger will get (very) hot during charging and will cool off when it is done charging.
My recommendation to fix the sometimes charging/sometimes not charging problem is to pull the cord out of the plug unit and plug them back together. The cord is a little finicky and so it might need to be reseated. Make sure the cord is plugged ALL the way into the plug unit (it can be a little hard to get them to be perfectly together).

I have called Asus on this issue and while they agreed to RMA the charger I just can't be without it right now so i wait. Chargers getting warm are normal, but chargers getting as hot as mine does is not normal and not good. I would estimate this charger is getting in the 160-180 degree range. Mine has also failed to charge on one occasion. One post i ran across said to change the polarity of the charger by turning it over so that the word ASUS is upside down when the viewing the outlet with the ground pin below the prongs. Seemed to help but not sure if its actually better or just wishful thinking, ymmv.

Turning the charger over does not effect the heating of the charger, it simply eliminates the possibility of stray AC voltage on the shield of the cable and frame of the TF. The heating of the charger is caused by inefficiencies in the inexpensive charger and fact that it appears to be working close to its design limit. A few tips that have worked for me.
Use an outlet that good air circulation around it.
If used on an extension cord. sit on a heat conductive surface not on a carpet.
If tablet and dock are deeply discharged, charge separately and allow charger to cool between charge sessions.
If the charger gets too hot, it appears to shut off. Allowing it to cool generally gets it going again.

ASUS said i spoilt the power plug
sigh...i bought 2 units of EEE PAD **** TRANSFORMER...2 of the power plugs also loose...after 2 weeks of use...they said i spoilt the plugs and is not under warranty..i need to buy replacement...
how low quality is ASUS product or eee product...????

The charger and plug for the wall are a 2 piece unit. Ensure that that end that contains the wall prongs is seated all the way down. There is a line between the 2 units. The pieces on both sides of the line should be flush.
Regarding temperature, mine gets pretty warm. Warm enough that I would not want to handle it.

Dock won't charge but still charges tablet and functions well.

I've seen many questions about the dock but can't find one that talks about this issue I just had this morning.
Last night both my tablet and dock were charged completely. This afternoon I start using my tablet and notice the tablet is at 30% and the dock is fully discharged at 0%. I plugged the keyboard in connected to the tablet to charge it. The tablet is charging just fine but the keyboard is flashing the orange light and is not charging. I have tried plugging just the keyboard in and it is still flashing orange and not charging. I thought it could be the power supply but the tablet itself is charging just fine.
Does anyone have any ideas I should try before trying to see if I can get a replacement?

When the dock is fully discharged the red led will flash for a while when your charging. It's normal, when you have charged for a while it will be constantly on!

Defective. Exchange dock or send to Asus for repair.

I don't know what happened but I left it plugged in all night yesterday and this morning it was half charged with the light on orange so I'm hoping that sometime when I was sleeping it fixed itself.

A whole night charged and half charged still doesnt seem right... If its all fully charged now.. it a matter of time when it will happen again..

I've had a dock die and just flash with no charging on the prime before guess it was defective. Picked up an open box from ebay for 90 bucks works like a charm.

I got the dock to charge, but had to monkey around to get it to fit just right....still not fun....

Got it solved by doing a cold boot.
Turned it off then held power + vol down combo untill I saw the text "cold-coot linux" apear, released the buttons and waited boot.
Now the charging light is blinking.on the dock.

Ok. Honest mistake. It wasn't charging. It blinks when active (connected to tablet and tablet unlocked...if you lock the tablet the dock led stops blinking).
Tried the cold boot thing described above. Didn't work.
The charger charges the tablet alright, but not the dock.
Opened it up yo see if there was something wrong (cable disconnected or so). Unplugged and plugged everything back. Still won't charge. =/
Any ideas????
Thanks in advance!

Got it to charge using a pliers. Images attached.
Apparently or my dock jack is bad or my cable connector...most probably the dock. =/
Any ideas on what to do now? Where can I get this jack? Is it not extremely hard to replace? Worth it?
I'm in Brazil, so I got no official ASUS support for this piece. =(

I have the same issue, and after reading your post, I tried your hack and the charging light finally came on for my dock. Evidence strongly suggests its a flaky electrical connection in either the cord or the jack. I am leaning towards jack because my cord will charge my tablet when directly plugged in, but I am not yet convinced.
Noticing that the connector's pins are on the outside, and it connects to a double-sided blade of pins, I tried to squeeze the connector some to make a better electrical connection. It was a little better, in that I could occasionally now get the charging light to turn on for a few seconds by applying pressure to just the cord's connector, but still not reliable. I then tried to use a small blade between the plastic and outer metal casing of the cord's connector, and I destroyed the came and now it won't even charge my tablet. I'll have to go to the store tomorrow to replace the cable, and we'll see if a new cord works to power the dock.
There's a distinct possibility that a new cable might just be all the fix I need.
Looking at the teardown on ifixit, it seems like the tablet uses a slightly different connector housing than the dock. Perhaps the dock has a less reliable part.

A new cable did not fix it.
Without another good path forward, I get brave and have attempted to reshape the receiver jack's metal housing to be more snug, hoping that a squeeze would do it. I have only managed to mangle it further.

Wireless charging and times needed to place on charger to work

A few weeks back I bought a wireless charger off eBay for about £10 (I really didn't want to pay over £40 for the official one if I wasn't going to use it much), and I'm sure I've read something somewhere about someone saying the S6 doesn't always charge properly on the first placement on the wireless charger, and they need to pick it up, and place it down again. What I was wondering is, is this normal? If so, how many times do you guys need to place the phone onto the charger before it actually starts charging properly (and doesn't stay awake saying "wireless charging paused")?
I'm finding it rather irritating, and I will upgrade to a better charger if that's what the problem is. If you could mention what kind of wireless charger you use when responding, that would be really great!!
Many thanks!!

I received my wireless charger with the Samsung promo so I got the official one. I need to place the phone a certain way which just is with the edges to the back/front and in the middle and it charges instantly without problems. I never had any pauses unless I take the phone off it.
Dunno what other people experience with it but there fine for me.

I've been considering investing in a wireless car cradle but I've heard a lot of stories where people have had issues with getting the phone perfectly aligned so it would charge. For me wireless should be easy. Just plop it down on the pad and it would charge, quicker than plugging a cable in but it seems in reality people have to move the phone about until perfect alignment is achieved. Such a shame.. Although I've just seen a wireless pad that has alignment LEDS that light up to show either incorrect or perfect alignment. Maybe that feature would make it easier? I think i'll hold off buying a wireless charger for now at least.

Ive had two of these with mixed results
http://www.amazon.co.uk/CHOETECH-Wireless-Charging-Motorola-included/dp/B00JA7HNZO
you have to place the top edge of the phone at the top of the charger, far from easy.

I have the official wireless charger as got it free with the phone.
You have to place the phone just right which hacks me off. But once it's on it charges perfectly.
It is a pain if you want to quickly check the time on it in the middle of the night and then blindly have to faff about trying to place it perfectly on the stupid pad to get it back on charge.

The charger I have has two LEDs. A red one for "power connected" and a blue one for "charging device". Sadly, the blue one lights up even when my phone is in its "charging-charging paused-charging-charging paused" mood.
If you guys are having trouble too, at least I know it's not my pad

I oftentimes place my phone on the charging pad only to have it not start charging. If I pick it up and set it back down again, it will start charging. I have no explanation.
