[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.

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.

[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.

Charger died

So my co-worker has an Asus transformer like i do and he is on his 3rd charger for it. So i have been lending him mine while he waits for his new one. So last night he borrowed it and when i went to charge mine it no longer works. Are the chargers really this faulty or could it be his device that is killing the charger?

After charging my tablet for a while or overnight the charger does not work either.
So what I do is either wait it out or throw it in a ziploc bag and toss it in the freezer(I can't remember where I found this tip but it does work).
The charger gets excessively hot after 2 hours of straight charging and as a safety feature I believe it shuts off. Throwing it in the freezer simply resets the charger I believe, and it is only for about 15 minutes.

They definitely have different versions, the later version 0B-2LF, 0B-3LF (?) are supposed to be less failure prone.
You can always make a Do It Yourself (DIY) charger with a wall charger and USB A Female to 5525 Plug Female Power Adapter.

I’ve got similar experience – when I’ve tried to charge tablet second time after few hours of playing with it, when I’ve plugged charger in, icon didn’t show me expected “charging” icon. At first I’ve thought that was faulty cable but plugged to PC worked fine. Then I’ve found some info that connectors between charger and plug adaptor tend not to have a contact. I’ve taken out plug adaptor and bent slightly those 2 wires on charger, then connected the plug adaptor back. When I’ve plugged it into wall socket – it worked. I’m on 0L-1LF model.

I've encountered this problem too. At first I thought the charger was dead, but when I rebooted the transformer while plugged, it start to charge again. Maybe you should try that.

It probably still charges or has some charge optimization like my Lenovo laptop has. Mine does the same but never any issues.

Another succesful "freezer" here.
To document - My powerstrip turn off with PC and charger is plugged in to it. Tablet was @ < 20% when I put on to charge, not realizing strip was off (company in town so wife wanted it off in case room was needed for kids), got up next morning and now tablet @ < 4%. Took charger and tried multiple outlets and none would charge and charger was not warm. Tablet @ < 4% and now plugged to USB port on laptop (recongized USB Debug and Asus Sync) so it is trickle charging sort of. Search turns up this (and a couple of others) tread. Turned off tablet (to improve trickle charge performance) and waited the 15 minutes. Removed charger from freezer, plugged into wall, plugged in tablet and tablet turned on and now shows as charging.
I assume this is a hardware/software/firmware problem in that the charger is not going to burn itself out trying to push too much voltage and the reduced charge state of tablet is raising resistence and the firmware has a pointer wrong and it needs to be a little colder to be right.
No idea but thanks for the tip.

I got kinda freaked out when my charger didn't work with my tablet last time. I blamed the custom rom since it happened a couple days after I rooted and flashed a custom rom on it, and I never had trouble with stock before. But, it wasn't the charger, since I plugged in the dock and it could charge. So maybe sometimes the tablet doesn't take in a certain amount of voltage or something..? (It was fine after I rebooted.. or update roms, can't remember.)

I once thought that my charger had died but then I tried a hard reset (hold the power button down for 10 seconds) and it started working again. It's worth giving it a go before you go out and buy a new charger.

I think there is something off with his TF if it killed 3 or 4 chargers.

My charger died and no amount of putting it in the freezer or anything else would make it work again.
The only thing I did was pull the cable out attach the TF to my laptop and download files to a different Micro SD card I had bought. Plugged it back in and no workie.
Lucky I had bought another charger for a spare and had it to check the cable ..charger and make sure it what part actually wasn't working...and charge my TF.
It's at an ASUS service center hopefully being fixed.
They do go bad. Theres been documented problems with them just like the dock,, and tablet. When your trying to build the cheapest tablet around ...parts and some things provided by other manufactures ( I know Asus doesn't make everything that goes into it) don't always turn out as well as you've planned.

[Q] My TF101 wont charge but it connects to the computer

Well I let it drain all the way one day by accident. Then when I tried to charge it with the stock cable and a non-stock brick it would take hours for it to charge fully. Also it did not charge while it was on and being used. It would have to be turned off for it to charge. So I quit on it and left it in the dust for 3 months. I then bought a new cable thinking that the cable was the problem (it was a 3.0 USB cable). it was also a fail. It charges slower than before. I dont know what the problem is. While it was on 3% battery I did a factory reset thinking that would fix it. It completed and still nothing. is it broken? Or am I doing something wrong?
help me please!

Turn it off. Connect to your PC's USB port for 6-8 hours. Put the ASUS charger in the fridge for 30 mins while pc charging. Then allow charger to warm up to room temp and plug into TF101 and it should charge.

Thats not the problem. I have multiple back up chargers. I have two Samsung GS3 chager bricks. They charge perfectly. The cable is brand new. The tablet just wont charge quick after 3 months of battery being drained. IDK what to do... :crying:

I was told there is a switch on or near the battery for this problem, don't quote me on it, I am just repeating what I was told and have not tried it myself but if you have nothing left to try, it might be worth checking

It seems A LOT of people have this problem with their charger on the Asus tablets. The problem is the power brick not supplying the required 15V to charge the tablet. It still supplies the usual 5V which makes it charge very slowly and ONLY when the screen is off or the whole device is turned off.
Anyway... either buy yourself another charger (those cheap ones on Ebay for $11 will do the trick) or make your own from a spare 12V power supply you got laying around the house and female USB cable end (like I did!).
