[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...

Fried eee pad?

Well ladies and gents, I think either my eee pad has been sucked dry or the charger fried, or both. I went to turn on my pad and found out that both the dock and tablet were at 0%.
I plugged it in got it booted and after an hour, the orange light on the side of the dock stopped blinking and stayed orange, as if it were charging, but the pad still showed at 0% for both pieces. I unplugged the charger to find it was so hot it was almost untouchable and as soon as I unplugged, the tab shut down. Also the dock was not usable to type while plugged in. Am I screwed with this piece?

Zip lock bag your charger and put it in the freezer.

lol really? put it in the freezer? Hey test the usb cable first by connecting it to the computer and see if you get a response. If so for the most part you have like a 90% chance its not the cable. More then likely the adapter is messed up as stated above. The AC plug itself is detachable, its hard to get off but it comes off. You will see its two pieces one big piece and a slimmer piece. Dont rember witch direction it SLIDES off but it comes off. Just check around it and make sure its not blocked or anything. But yea might have to get a new one.

Really. There is a heat sensor in the charging cube that disengages the link in case of overheat. Zip lock bag is there to keep out moisture.

Crazy. I unplugged the charger, let it sit. Plugged it in 20 mins later and all of a sudden my tablet has 60%. This thing is weird. Gonna have to teat more thoroughly ans possibly get a new charger

Good. Just remember. If this happens again but next time the safety won't just disengage, then throw it in the freezer like I instructed.
Added by edit.
Then of course chances are you won't do this. Most people are not modders because they are too afraid to do anything out of the ordinary. This is why the ipad is so popular. Anyway, if this is your case, then I guess the alternative is to get a new charger.

I just want you to know that i tried Goodintention's advice and it worked for me. That being said, do not wait to get a charger replacement by following DevCake's thread on how to make up your own charger for the TF. Once these chargers start going bad the only way is downhill.
My second charger died yesterday and I am following Devcake's advice.

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.

[Q] Need Replacement Charging Port

The tablet needs a new charging/interface port and was wondering if anyone knows where I can get one?
I have searched Ebay and the net for a used/new one. The port looks fine but when plugging the cable in it won't charge. Sometimes I can get it to if I push and hold it just right however this is tricky to do and does not work often. So right now it is a dead brick. The pins must not be making full contact for some reason.

Ive bought parts from these guys before, I don't see a charging port but might be worth giving them an email and asking

Thanks but I would rather not have to order parts from Sweden. If I have to I'll just keep watching Ebay. Every so often one pops up but doesn't last very long.

Good luck
The parts I ordered took about 4-6 weeks to arrive iirc

Just installed a new (used off Ebay) charging port with fingers crossed that it will allow the tablet to charge. I also have a new high quality charging cord (PWR+) and two ASUS wall chargers that I know work. Plugged the tablet in and was relieved to see the tablet come right on and show it charging. Let it charge to about 20% and then decided to unplug it so I could put the ring back on the tablet so it is all back together. Get the ring on and plug the tablet back in and nothing. I'm about to throw this thing in the trash right now. So fed up with these charging issues. What changed? All I did was unplug it, put the ring on, and plug back in.
So for kicks I decide to try the other wall charger and what do you know....it came on immediately and started charging and is still charging. I'm afraid to touch the thing now. Seems once it is charging and undisturbed it will charge to 100% no problem. However, when going to recharge it won't charge. Could there be something in the charging mechanism causing the thermal to trip in the wall chargers? Is there possibly a small short somewhere in the charging mechanism? Anyone have an opinion on why this is happening? Only other thing I can think of is doing a full wipe/reset and maybe flashing another rom (is currently on newest Android Revolution HD) once it is charged up.

Could the ring (I assume you mean Bezel ? ) or the screws near the port be shorting the charging port to earth/ground/chassis ?

Yep.. Sry.. The bezel. Not sure how but anything is possible. Would indicate to me a faulty charging port or charger cord and is happening on multiple. Tablet is still allowing me to charge it at this time after switching chargers and with the bezel on so will have to see how it goes.
Sent from my tricked out S4.

Fingers crossed it was a coincidence with the first charger, if not, I'd try taking the bezel off again and see if you can spot the short / see if it works again with the bezel off, or even just with the screws out

Phone confused about charging

Hi guys,
I haven't been able to charge my phone properly for a while - after reset when I plug in the original charger, it charges fast, when I unplug it and plug it back in, it charges slowly. When I unplug it again, it still shows the charging icon forever but it won't charge when plugged in. Factory reset doesn't help. The phone also randomly shows the USB moisture message even though it never got wet. Changing cables and power sources doesn't help.
Build MHA-L29 8.0.0.375(C636)
Thanks for any ideas!

Blow out the USB charging port on the phone. Also, use a toothpick to GENTLY clean out the port of lint and dirt.

And use app that tracks your charging speed. Try ampere In playstore.

Thanks for the reply. I tried that already. Is it possibly a battery issue? I wouldn't mind replacing the battery, which is cheap rather than replacing the phone because of such nuisance.

Thanks, good idea.
Ampere clocks in at -250 mA after reset. Goes to around 1800 when plugged in to a third party charger, which drops to around 300 mA when unplugged (phone indicates that it is charging). After reconnecting it goes up to 1000 mA. I don't have my Huawei charger at work but it's similar - at first plug in it charges fast, after reconnecting it switches to the slow mode.

You should use your original charger. And see if supercharge is working. If not. Give it a shot in a service center. Theyll fix your phone for free if you still have warranty.

Well, before replacing the battery, try this:
- turn phone off
- connect to original Huawei Supercharge charger and charge up until 90% or so
- disconnect from charger and turn on
Use the phone as you normally would until around 35-40% remains, then try connecting the charger. If the issue persists, I still believe it is a problem with the charging circuitry rather than the battery. Especially if we take the moisture in the USB port message the phone shows. Replacing the USB charging circuitry should not be a big problem AFAIK, it is connected to the motherboard with a snap-on connector, replacing it should be easy as disconnecting the connector, removing the circuit with the port and placing the new one in.
Yep, I guessed it: https://www.youtube.com/watch?v=4avHFWjsz4k
Are you having issues where the phone is displaying 30 or so percent battery remaining, but the phone shuts down?

That's a great point. I didn't know the USB circuitry can be replaced by itself. I don't have any issues with the phone switching off. It uses the battery all the way down to 1% or so. I don't see any erratic percentages. I'll replace the part and update you on what happens. Thanks!

Yup, that was the problem. Easy fix. Thanks for the suggestion!

Make sure your microphones still work. I had to replace my USB charging board (which also contains the mics) recently and the first one I tried had a bad mic. I could make phone calls just fine, but google assistant couldn't hear me. I got a replacement and both mics were fine.

I wish I could close this thread but a lot of weird stuff happened since I "fixed" the phone.
Since I bought the battery before I was told it could have been the USB board, I replaced the old battery too. The first charge was smooth and I drained the battery to 0 as recommended. I plugged it back in and it charged to 5% and stopped. I noticed a chemical burn smell that I later realized was coming from the USB circuitry. At this point there was no way to charge the phone but when tried to turn it on, I still saw the red charge icon. I opened it up and put the old defective USB board back in and I was able to charge it. Throughout the day I noticed weird battery drain that I saw recently before the replacement of the USB board. As usual, I tried to restart the phone to fix that but it won't turn on. The battery was at 85% when I shut it down. When I try to turn it on, it won't even show that red charge icon. Nothing. I can't put the old battery back to see if that's the problem, because I bent it during replacement.
Could it be a battery issue this time or is the phone just dead at this point?
