[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] Shocking Transformer

I've had my transformer for a little over a month. Today I notice that I was getting shocked by my transformer. It isn't really bad, kind of like a 9 volt battery.
Is anyone else experiencing this? could find it on the forum.

Are you sure it wasn't just static charge, since you only had it once, as I understand. And I don't get shocked by 9v batteries, I can only taste them when putting them on my tongue

Happens to me occasionally (only when docked), and I've seen several other people mention it here. I think it's just a grounding issue.

Noticed something similar yesterday. TF docked and charger pluged in. When touching the dock there was a small electric prickle. First thought of static charge, but it remains until I removed the charger.

mee too, got an eee pad with dock today, first charge, touching the dock I get a small eletric shock....
Any solution?

It's a common issue. The back casing of the Transformer has some current in it and if you touch it under certain conditions you can meet the cold metallicly feeling you get from something like a 9v battery on your tounge. I don't believe their grounded properly. If you hover your hand 1/4 inch from the back of the case you can also feel it.

I just had this.
Turn your power adapter the other way up. As in, take it out of the wall, turn it the other way up, and plug it back in.

There is a thread in this forum.
Strangely enough: the solution is to flip the charger round.

I can confirm turning the adapter 180 degrees and then plugging it in the wall socket again stops the buzzing feeling when touching the tablet and dock.
Doesn't give me a good feeling on the overall build quality. Even worse now my dock has stopped charging.

After some weeks I never got again that electric feeling on the dock.. it seem's that it was electrostatically charged when it was new...

Power adaptor gets very warm

My Eee pad came with a UK power adaptor. I have noticed the adaptor gets very warm even after it has been charging for a half hour or so. It's a lot warmer than I would expect. Is this normal behaviour?

Seems to be. Mine gets warm when its charging, when the TF isnt plugged in or the TF shows charged it cools off. Not hot enough to melt anything but definitely warm to the touch, even warmer than my laptop adapter. Although, I should note it gets nowhere near as hot as a kingston laptop adapter I rented from Best Buy a while back.

My adapter gets super hot when I plug in my tablet when docked and both have dead batteries. After seeing pictures of people's adapters melting, I won't let mine charge from dead unattended.

i believe its warm due to the high charging rate. considering the fact that it only takes 4 hours to fully charge a tf from flat.
from personal experience, charging batteries at higher C the charger itself will warm up.

Wireless Charging Hot

Anyone else notice that the wireless charging seems to be somewhat erratic in battery temperature increase?
Yesterday I put my phone on the WPC-700 and the battery temperature was up to 47C after about five minutes. I took it off the Qi charger, plugged it in to UBS and it was down to 35C. Today I tried it again on the WPC-700 and it is 37C after about 5 minutes.

Wireless charging = heat. Its a waste product of how it works and part of the reason why its slower to charge and less efficient. Its not the battery itself that's getting hot (at least not directly) but the coils used to capture the electromagnetic field produced by the charger.

Some chargers are a bit picky about alignment. If your phone and charger aren't aligned right, you can get excess heat and/or slow charging.
I see all the time where everyone likes to plop their phones down at an angle, relative to the charger, and while that may work with SOME chargers, it's definitely not recommended for all of them. Try placing your phone on the charger in exactly the way that the charger expects (look for a picture or diagram in the instructions or on the charger base). If this reduces your heat, then you have a picky charger.

Thanks for the suggestions. The actual battery temperature is warm, not just the device, significantly more than using USB. I"m just not sure if 47C is too hot or just right.
I have the phone aligned properly, I was careful to be sure the magnets grab best in how I placed the phone. I decided to order the Google charger and will see if there is any difference.

Back of phone producing 24v AC when charging

Hello,
For a while now I noticed that when my Xperia XZ phone was plugged in, the metal back of it had a somewhat different feel as if it was textured. Today I decided to test it with a meter to ground to see what the potential was. It delivers a 24 V AC charge when plugged in. It is always delivering 24v and the current is extremely low. This occurred with both the official charger and cable, and an anker charger with anker cable. Does anyone else get this? How on earth would a phone getting a DC charge put out 24V AC?
To test just plug your phone in and lightly drag your finger along the back. Do the same with it unplugged. If your phone is the same as mine you will feel a texture like feeling when it is plugged in, and none when it isn't. I can't see this being a defect as it would have to transform DC somehow to get the AC power. Strangely too my phone now always says that it is providing power as a USB device perhaps that is an issue.

That's common, it's the battery grounding itself via the back metal panel of the phone.
It happens in many phones and usually laptops or tablets, nothing dangerous or defect.

Happened to me once, I reconnected the charger to another socket & it was fixed. Never happend to me ever again.
This phenomenon is called Current leakage, although it might not be hazardous as the current is very low but any sort of leakage could be dangerous.
I would suggest changing the charging socket. If that doesn't work maybe you should try to change the wire & the charger and see if it happens again.

Are you using the original charger? It is likely to happen if the ground pin of the charger is actually not 0V.
