The title says it all. The device refuses to charge or detect my charger. I am not sure what to do or if anything can even be done.
What would the "next step" be?
Is the liight on the charger on?
Is there 12V on the charge plug?
If yes, send it back.
The answer to both of those is yes.
My next question is how much would it cost to get it fixed by Viewsonic (a rough estimate)? I only ask because my warranty is shot due to me flashing Vegan 5b.
I called viewsonic and as it turns out they cannot fix devices that have been flashed.
So, unfortunately I have a brick that will not charge.
If you have any charge left, I would nvflash it and get it back the original firmware and kernel. It's really not difficult to do. Then I'd send it in for warranty repair.
That's a good idea, but my device has enough charge to turn on for only one minute.
Not enough time to reflash the original firmware and kernel. I was unaware that it wouldn't charge until it refused to light up.
Will it run with the plug in?
I tried this and it seems to work. Plug the power supply into the Gtab with it powered off. Hit the right side of the tablet on the edge slightly. This worked for me to get the red light on(I hit mine about three times and the red light came on). Mine only charges while plugged in but I still get a full charge even thought the battery indicator shows 0%. I have used mine all day today without a plug and it sits at 0%
Your idea intrigues me... you tapped it, eh? Well it's worth a good shot, I'm about ready to try incantations!
Okay, so the light on the charger is on. But is it really charging. It could not be charging or have a bad cable or......
You need to find a way to make sure the correct voltage is coming out of the charger plug (the specs are on your
power adapter/charger).
And if you know the charger is actually charging....
I don't know much about the inside -- there are some posts about things like this
from along the way since November. But it might be worth your while to open the case and make sure it's not something as simple as a wire that has come loose.
Also, if it is the charger you can go on the web and Google for MPA-630 power
adapter (it also is used for those digital picture frames) and find a replacement.
Good luck. I wouldn't give up yet!!!

...I could lick the charger I suppose that would prove to me if the tail end is receiving power from the head.
I am not a man who gives up, but I do lose hope very quick.
You know, in my head I'm going over a list of things that I can do to inject this device with any amount of energy. Just enough to enable me to reflash the stock on...Buying a dock, replacing the battery with a spare fresh one, throwing the whole thing on top of some power lines...

heh, well I tapped the hell out of that thing... nope (In my heart I didn't think it would work)
I should also say that there is nothing loose, I shake it... and nothing is rattling.
With the DC plugged in, try gently and slowly wiggling the connector left, right, up and down and see if the RED light comes on during the wiggling. If it does then the pin on your DC IN Jack is loose due to failure in the soldering joint holding the DC Jack to the motherboard.
IF you know how to open the Gtablet, you can can resolder the connector. The DC IN Jack even in laptops eventually fail and need to be replaced and/or resoldered. For this reason, I purchased the dock as a backup method to charge the Gtablet.
China computer products are known to be sometimes undersoldered.
Try Googling "loose DC Jack laptop" for more info.
This assumes you power adapter is good.
Hope this helps.

I wiggled (very slowly) the connector in very direction possible. The red light still didn't come on and the jack felt a strong as ever.
...Maybe it IS a problem with the adapter itself? however, I still don't think so...
Buy a doc from i2steve here on xda. You will have a sweet new accessory and an alternate charging method. Worth it. At that point you can charge it, flash it and send it in for repair. Or if your lazy like me, just use these doc to charge it and call it good.

hi i recently loaded a new rom on my g tab after id finished it started up ok but plugged my charger in and behold it did not charge no charge light on, so did a few checks with my multimeter found no supple coming from the power charger.
just thought id reply to your enquiry. so im in the throws of buying a universal charger with the same power requirements. hope this helps. yorkygeorge.
Try going to an Office Depot or a Sears and see if they have a G on display. if so, plug yours in to its power adapter. At least then you can rule out your power supply.
^ nice. Really good idea
If you have a 12V adapter with Cigarette plug lying around the house with the right size plug on the end. Try plugging it into your car ( engine off). The voltage on the adapter is 12V.

as i tire of hunting for hours for a thread i post. here goes...
for some unknown reason my g4 8125 wont charge. it went dead on the charger and i was thinking that my wall charger had freaked out. well after about a day of sitting i hit the power button and the lights came on! well it was a built up charge so i know the phone didn't brick. i put it on the usb cable to see if the red light would come on and no such luck.
any ideas? r they known for suddenly ignoring the charger??? any help is great!
oh and i haven't modded anything but the carrier unlock.
*i found on ebay a few that were selling with the charger port "broken" ... this a common thing? it able to be fixed if so?

I had a similar issue a few months back. It happens that the wizard needs a minimum charge on the battery in order to being able to charge. It´s like the charging connection is made by internal software.
Probably you drained too much the battery to a point that it no longer can sustain the cellphone on enough time so it recognizes the charger and it starts charging.
The workaround would be to jumpstart the battery.
There´s a post on thiss matter but in order to give you a straigth answer, you will need to find a low voltage source (better of 5volts or less, DC). Many users have used the usb port on their pcs, cutting out a cable.
Then you will need to remove the battery from the phone, and find the (+) and (-) sing. Probably you will find that there are more than 2 power connections on the battery. I assumed that the + and + were the most outer ones and it worked for me.
Then you would need to "connect" the power source cables to the battery. Beware of the polarity. keep the cables there for about 5-8 minutes so the battery would have a charge on it.
I personally used as a power source, a small 4 AA NiM rechargeable battery pack that gave me 1.2 volts x 4, meaning 4.8 volts. So even when the battery is only 3.7volts, a 5 volts power supply as the USB port, would do the trick. Just be carefull not to overcharge the battery. If you feel that the battery is getting hot, then probably something went wrong and you must stop and recheck the polarity. After 5 minutes the battery shouldn´t heat up too much on a 5volts surge.
To use the USB you just need to cut out an old usb cable that you don´t use (from an old mouse, or anything similar. Find the black and the red cables (the green and white are data cables, so don´t mess with those). and use them to connect to the battery with your fingers.
Tell us how it went.
thanks as always you guys are like the boy scouts...always prepared!
at least i think that's their motto...isn't it? anyway thanks a million
This part of the forum is covered in different charging issue threads due to it being such a prominent feature. Things ranging from model numbers, overheating, not working at all and only working intermittently.
I thought I would attempt to build a thread of the issues we Transformer owners are experiencing and seeing if anyone can really get to the bottom of this.
From what I have picked up from the forums many people are getting bad responses from Asus support, either providing no help at all or asking for the entire tablet+dock+charger at the users expense for shipping.
Common problems outline
[1]The brick gets very hot and stops charging
[2] The contacts between the brick and country adapter (e.g. USA/UK/EU) don't contact properly.
[3] The brick refuses to work altogether for no obvious reason.
Solutions attempted
[1] Bending the two contacts between the brick and country adapter slightly away from the brick (1 - 2mm)
[2] Calling (a somewhat unhelpful so far) Asus and asking for replacement
[3] Preserving (Not very Fun)
--------------------------------------------------
The problems I am experiencing myself are basically that the charger works sometimes perfectly and other times not at all.
I can plug my charger in sometimes and it will work fine, others I can plug it in and my TF doesn't indicate charging although it does charge just VERY VERY slowly (about 2% every 25min).
Heat has not been an issue for me as it has been for many, my charging cable doesn't got warm at all and the brick is never alarmingly warm, nowhere near as hot as my laptop charger gets and the Asus charger is only 5V less than my laptops charger.
Model Numbers
Model numbers have been spoken about but so far I cannot find any evidence that they are different from one another, a known fault with 0B-LF so issues reported to Asus with that model should be find, but as far as I can tell problems with these power bricks happen across all the models (0B-LF, 0B-1LF, 0B-2LF)
If your having issues with your power brick post them below so we can try to keep them all in one place and hopefully try and resolve this.
As you are in the UK i'm not sure if this would apply to you but from my personal experience, i've had situations where the charger itself would be quite warm to the point where up close you can smell that aroma of overheating electronics. The charger has also refused to charge even when not hot, but will work once again after i've taken it off the mains and let it sit.
The american outlets differentiate between the hot and neutral leads via the larger and smaller prongs. I read in another thread concerning polarity and surface charges that when the charger is plugged in with the prong on the A side of the ASUS logo towards the larger (neutral) hole, then the charger will work properly. This has been my experience. I've come to a personal conclusion that the design of the charger is such that it is pole-sensitive but asus didn't bother to tell anyone which prong goes where, hope that might be of some use to you.

I never have had my charger get hot enough to smell like burning. The only way so far of resolving the issue is leaving my charger unplugged for about 20 min+ and then reconnecting it to my TF.
You forgot the "stick the brick in the freezer" trick.
Not kidding, it worked like a champ for me and a few others.
Put the brick in ziplock bag and stick it in the freezer.

You know you can achieve the same result by just letting it sit without being plugged anywhere between 20 - 30 minutes. Just in case you don't want to put it in the freezer anymore.

Yeah that's what I have been doing, if I plug in my TF and it won't charge I just leave it unplugged for about half an hour and then plug it in again but this is a bit of a pain. Could really do with a better solution.
-_-
Today my TF is refusing to charge at all. It trickle charges from the charger but this takes forever, its gone up 2% in just over 30mins. I'm not sure what to try now.
I have plugged it into charge, didn't work, left it unplugged for 20mins, plugged back in, wouldn't charge, left it unplugged for an hour, plugged back in, wouldn't charge, left it to trickle charge because it only had 1% battery.
I'm not sure what to try now, I might have to call Asus after I go on holiday.
Seems my charger will only trickle charge now, I cant get it to charge properly whatever I try. Maybe I should put it in the freezer for 20mins and see what it does......
If you do the freezer trick, let the adapter sit out UNPLUGGED for a short while.
Introducing heat can result in condensation (water) and we all know water and electronic bits don't get along that well.
Vendors are starting to get stock in spare chargers these days. I just got one in last week. Never had problems with the original yet, tho. The new one is going to the office where it will stay.

Get a new one, and if it works normally, toss the original one in the box and exchange it at the place you purchased the second one at.
If ASUS won't replace it under warranty, the above will end up with them replacing it when the vendor returns it to them.
I've done some research and as far as I can tell the TF power brick operates in two modes, one is for lower powered 'ordinary' usb devices, such as my phone. This allows this charging brick to charge at 5v @ 2amps outputting a total of 10W.
The second option is primarily for when a TF is connected and runs at 15v @ 1.2amps outputting 18W.
My charging brick seems to charge my phone on the 5v mode fine, but when I connect my TF it isn't charging properly and takes ages, this leads me to believe that somewhere down the line my charging isn't connecting something somewhere and allowing for the 15v charging to take place.
Would I be right in saying this or am I talking all jibberish?

I'd agree. Something in the solid-state(a mosfet or IC) has crapped out due to heat, breaking the 15V section of the charger. Time for a new one. It's possible there's damage to pin 7 in the usb port, but heat-fry is much more likely.

Yeah definately taking it back to retail store I bought it from, hopefully they will try it and just give me a new charger then and there.
Info I've gleaned, just in case it might assist someone:
1) I took delivery of an 0B-3LF charger today from ASUS UK, haven't seen any mention of the 3LF yet on XDA. It *appears* to generate less heat but that could just be a placebo effect.
2) Coincidentally, my 0B-2LF - which always got hot when charging dock+tablet simultaneously - failed last night. Unplugging it from the mains then replugging it did not fix it, even though it was cold to the touch by this point. Six hours after unplugging it from the mains, I tried again... the 0B-2LF started working, and continues to work. So if your charger fails, unplug it, give it six hours, then try it again - ideally before registering an RMA, otherwise you'll have to spend an extra half hour working out how to cancel the RMA (answer: email [email protected] with your RMA number, serial number and case reference).
My charger works whenever it feels like it wants to. I've been messing with it for the last 30-45 min with no luck. Unplugging the charger from the outlet, trying different outlets, unplugging and plugging back in the usb cable, with and without usb 3.0 extension, rotating the mains to switch the polarity, pushing out the prongs for the country adapter, widening the opening in the prongs, banging the charger, letting it sit and nothing is working. Just now it turned on, but right after the boot screen, it made the low power chime and died.
Seems like the problem is getting worse. Before when it first stopped charging it was really easy to get it charging again.
Also my father got the TF within the same week i got mine. He went overseas and came back to visit again and his charger has no issues. But i did notice he keeps the USB 3.0 extension along with the usb cable all plugged into each other into the mains whereas I unplug mine and wrap them up when taking them along.
Think that might have something to do with it?
my charger is a 0b-1LF

That's how mine started, but got worse. I only charge my tablet once a day and the charger is unplugged from the outlet between charges. Now I can't get it to charge. Every now and then if i unplug it and plug it back in, it'll boot up the TF but then the second the boot animation is over, makes the battery low chime, 0% remaining and shuts off!
Just got off the phone with asus tech support, they gave me an RMA number and i have to mail the charger to them to see if they can repair it.... whats up with that? why can't they just mail me a new one and i mail them back this broken one or get billed for it like every other tech company i've dealt with?
I've had the exact same issues as both of you. At first if it wouldn't charge I would leave it for a few mins and then it would charge straight away. It slowly got word and I had to fight with it more to get it to charge and now it will only trickle charge.
I will charge it up overnight tonight and leave it for six hours or more. Hopefully this will work until I can send it back.
(I'm not sure if i have mentioned this somewhere but my charger model number is 0B-1LF)
So I got an rma to send my charger to asus but I think I narrowed it down to the cable and not the charger. I tried my dad's charger and it works with that. Then I tried my cable on my dad's charger and no go, only trickle (5v) charge. Then tried my dad's usb cable on my charger and it worked. So I think it has something to do with the cable not telling the charger it needs 15v.
Going to call asus back tomorrow and see if they'll
Send me another cable.
asus rant: how come I have to pay to mail out my defective part and be without it while they repair or replace it? Every other company I've dealt with would send me the replacement and I would have to mail back the defective unit (using a prepaid label included) or be billed for it.

there have been other threads about this. usually its the charger overheating and putting it in a ziplock in the freezer, resets it.
Mine did that too, just leave the charger and everything unplugged from the wall for a day. That fixed mine.

The other issue I've seen is poor contact in the USB socket on the wall adapter. I had to unplug the usb cable from the wall adapter. Then, look at the usb socket on the power adapter. The gold pins are the usb contacts. Directly opposite of them, there should be two silver prongs. I had to use a small flat blade screwdriver to pry both of them out a little further to ensure they did their job of firmly pushing the usb cable against the socket's usb contacts. Once I did, my TF201 was able to get charge from it, again.
If you decide to replace the wall charger, I believe Fry's and Office Depot stock the asus charger.
Same thing for me.. PC recognizes it as a media device, but will not charge with wall charger. Wall charger works with my HTC Phone, so it works.
I don't think it has anything to do with the latest update, since the Dock wont charge either, and there's no OS in that, right?
Just experienced this today. I have had it unplugged for about 10 hours now, we'll see if it charges.
I had the same issue few days after I got my prime. I connected my sgs to the charger and it worked. Then connected the prime and voila-works.

C1. There are some good suggestions here I need to try.
Wrap it in a towel and bang it against a table. That will fix it usually. Then get some pc heatsinks and some arctic silver adhesive and you can attach them to the charger to keep it from happening again.
The plug has two options, 5V (standard for USB?) and 15V. I used the plug on my old HTC phone (Ozone) and then plugged it back into my Prime and it worked. Thanks for the great tips guys.
Since the charger works in two modes, I wonder if some charges became confused and started dishing out 5V when they should be dishing out 15V. Thoughts?

Hi, I got the same problem. The charger indeed seems to be stuck in the 5V mode, since, when plugged in the tablet does get charged, even though it is not indicated, but very slowly. It is charging as if it is plugged in to a pc.
I tried plugging it into (old) phones, but I still can't seem to get it to switch back to the 15V mode.
The freezer didn't help either.
Any other suggestions?
I waited about 4-5 hours before plugging into my old phone. My other suggestion is to allow the phone to charge for a short bit (30 minutes) unplug and wait, then plug into your Prime.
I have a feeling that its a transistor toggle that isn't flipping at the correct voltage.
I've had the same problem yesterday. In my case the problem was with the charge socket on the keyboard itself. Some copper pins were deformed and that stopped the device charging. I took a magnifying glass(also for checking if any of the copper pins are bend) and a small tool to bend them back. After this it charged again. Hope this helps.
My charger suddenly stopped working from today. The Prime is detecting the connection as the screen turns ON but it is not charging. I charged my sensation using the same adapter and USB cable and it is working fine. Why can I not charge Prime via PC like phone? Is it possible? I am in India and not sure if the power adapter is easily available as Prime is not yet launched in India.
Kindly suggest.
Thanks in advance.
Hi,
I've started to have this problem today, plug it in and it does come up with the charge icon but it doesn't charge - or doesn't seem to.
However I left it connected last night from midnight until 8am this morning and it went from 13% to 17% so it is charging VERY VERY slowly although the unit doesn't actual seem to think it is.
I have it plugged in to my phone right now and its working perfectly, I borrowed the charger to my g/f last night to charge her iphone and i'm thinking this might have done something to flip the voltage as since then it isn't working.
Anyone have any ideas on this??

I had to use a small flat blade screwdriver to pry both of them out a little further to ensure they did their job of firmly pushing the usb cable against the socket's usb contacts. Once I did, my TF201 was able to get charge from it, again.
If you decide to replace the wall charger, I believe Fry's and Office Depot stock the asus charger.

But if the charger works fine when charging a phone it cant be the connection at fault..
It does seem to me that the power it is outputting has dropped especially the I managed to gain 5% over the course of a night where WIFI was off and screen was off even though the charge icon doesn't come up.
Is there a way of forcing the charger back in to 12v mode??
damnit... I had the same problems a few days ago and I thought it was in the cable instead of the charger... not realising the charger has to put out 15v instead of 5v.
Does this mean the Transformer won't charge with for example, my HTC charger?
I totally messed up my cable, because I thought it was broken... when I opened up the USB plug, I noticed the yellow wire was not connected anymore, but this didn't solve anything. Eventually I messed up the cable that bad, that I've ordered a new one from ebay... but when I read this... I should have just banged the charger a few times... shait.

Has anyone actually ever managed to fix this problem? I've just contacted ASUS about it to see what they say - hopefully they'll ship me out a new charger plug or something, what a useless charger!!
*Sigh*...
Had the same problem with the TF101... After a while the tablet suddenly wouldn't charge anymore and it turned out to be the cable which suddenly went bad.
Now again the exact same problem with the TF201. This is pretty damn annoying, will contact customer support but am wondering if someone has experience with ebay cables that do work.
Already bought this one: http://www.ebay.nl/itm/ws/eBayISAPI.dll?ViewItem&item=130678359515&ssPageName=ADME:L:OU:NL:1123
But of course that doesn't properly charge either (oh, and I still have an original cable from the TF101 which works fine, so it definitely IS the cable). The tablet responds (turns on) and charges as if connected to USB port of the pc or something but doesn't fast charge. (Pins seem fine, nothing out of the ordinary to be seen).
So also a warning, be careful with charger and cable! Like the rest of the prime it is very sensitive to malfunctioning :/ Quite disappointed that they didn't address this with the TF201 as charger and cable were an issue with TF101 as well.
do you always yank the cable directly to detach ur device from the charger? I've been using mine for a long time now, it's still as good as new and charging well.
The key is to treat the cable like cheap failure prone chunk of crap that will fail. I got a second cord for power immediately. http://www.amazon.com/dp/B007LI2QJW/ref=pe_175190_21431760_M2C_SC_dp_1
Just took one look at that thin usb cable to know it isnt built to last.
when I was a kid stuff that was "made in Taiwan" was to be avoided, ironic.

Ehm, nope... I use it with care. Never pull at the cable but just take it out at the connector itself. But I guess you should always keep it in one straight line or something.

Hmmm, nice option... I think I also have a proper power adapter which simply supplies 12v all the time (where the asus one switches to 5V once fully charged). Does that matter? Being at 12v all the time?

After I'm done charging, I will keep them in a storage bag. Well TBH, I do fear that it's gonna fail. Coz it looks like a damn apple charger. that weak link
Put the power brick in the freezer for 45 minutes!
It fixes it for awhile.
My cable just went bad yesterday exactly the same way.
Gladly I've had a spare one that I have bought from ebay couple months ago.
I have to get another spare one I think...

The power brick isnt the issue... The cable from the TF101 works on both chargers, the cable of the TF201 on neither. The TF101 one is also from a spare powerbrick I bought coz I originally thought the charger was the issue as well. It's just a very feeble charger and cable, again...

This power connection is also a lot better fit for the dock power connector. I always felt like the one that came with my prime was going to fall out of the dock.
I have had the same issue. I bought the TF-101 for my daughter, and the first cable had the insulation sliding off near the connector after about a week. I saw that my daughter would rest the tablet on the connector at awkward angles, so I lectured her about being more careful and bought two more cables. When she went through those in a few months, I bought 5 extra cables. I know she is being more careful with them now, because they still look new when they stop charging. One of the cables I bought never worked. We are now on the last one of the batch, so I just bought 12 more.
It hasn't gone unnoticed that I am financially rewarding Asus for producing a shoddy product. We call that "the invisible hand of the market", right?
Hey, I just got my Z Ultra less than a week ago and I purchased http://www.amazon.com/gp/product/B00JEN5S6A/
I figured it would be easier to use then undoing the charging flap every time.
When I was trying the tip out without being connected to the charger I noticed the magnet was strong but didn't sit in the connector properly..
After looking at some other magnetic chargers online I saw some of them being plugged in upside down so I tried that and it sat in the port better.
When the phone was extremely low on batter (4 percent) I plugged the charger into the tip and put it on upside down. At first the phone restarted so I thought hmm thats weird and unplugged it, I then tried again and made sure it sat in the port snug and my phone turned off and wouldnt turn on again.. After about 15 minutes of the phone charging with no sign of led or charging symbol I found online to try the reset button and it finally turned on. I did some searching online and found out that the port isn't really meant for a magnetic charger but a dock and what I experienced was inverse connection.
So i am wondering if this could have possibly damaged the phone or battery in any way? I dont know if my battery life has been affected or stayed the same as it was the second day of having the phone..
Sorry for the long rant but I would appreciate any input. Thanks
You're not the first one to do a "reverse charging", and I believe that it will or can damage your device. The magnetic connector is made for the Sony DK30 dock, which costs around $30.
http://www.amazon.com/gp/aw/d/B00EC...200_QL40&qid=1404599682&sr=8-1#ref=mp_s_a_1_1
The thing with using accessories like you do, is that it's not a genuine product by Sony, so any damage done by say, a no-name charger like you're using, won't be covered by the warranty. If your Ultra catches fire in the middle of the night and you're using a " fake" charger, well tough luck. Sony won't cover that.
I would use a "fake" charger if the Ultra had a removable battery, in case it got damaged, but it doesn't, so you're really playing with fire right now.
Well to be honest I did not know the charger wasn't made for that until I experienced that. I've ordered the dk30 dock online as the sony store near me did not carry it but was wondering if I should be concerned with what already happened and get my phone swapped as it's still within return policy..?

i bought a aftermarket magnetic charging cable, plugged reversely and same as yours, couldnt turn on until i pressed the reset button to make the led lit when charging, waited a few hours plugged to the usb sony charger, led turned out normal. just when i thought it was fine again i noticed whenever i turned it off it turned itself on again and boot loop until i pressed the reset button to make it really off, plus, when it hit 15% battery life on the indicator on notification bar, it dropped 2% per second, yes, per second, and phone died. returned it and waiting for replacement.
see if yours has those symptoms, i think reverse charging does damage to the battery or the phone, see the shape of the tips of the charging port different, there may be a reason behind it.
edit: the reason i tried plugging the magnetic cable reversely was while i plugged it in normal direction, it showed its charging while it wasnt, thats y, and it was a cheap aftermarket one, i ended up buying a official dk30 from sony store

I have a Magnetic Charger - and I too experienced the shut down when I tried it upside down once.
I'm using a generic charger and haven't experienced any issues for months - just make sure to use it correctly.
This thread has me worried now though haha.

Im sure there has been one that the charger was the wrong polarity I think, and another where it was misused, that ended up with near dead batteries
I accidentally connected the charger in reverse, well the port is now dead. The phone thinks it's charging but the charger light never comes on and GSAM shows no increase in charge. At least the USB port still works.

Thank you very much for the warning. After reading this thread I was thinking that Sony should have keyed the connector to only plug in one orientation. I looked at my magnetic charger and that is indeed the case. One opening is round and one is oval, so the round opening will not fit over the oval contact on the phone. I guess the issue is the quality of the magnetic charger cable - a cheap one still may allow contact. The key is that the contacts on the cable are recessed into the housing so that the housing must fit over the posts on the phone before contact is made.
why in the name of all that is holy does the connector even allow for being plugged in the wrong way???
Cheap Chineese knockoffs. JUST DON'T BUY THEM.
Sony should have just gone with induction charging but oh well. As cheap as the GPe is right now, I'll just buy another one.

I just found this thread after plugging in my magnetic adapter in backwards. I have been using it for almost 6 months with no problem, and then this past Friday, I sat down at my desk and grabbed the charger and stuck it on without looking, and the phone shut off. You know the rest, now the magnetic port is done, and the screen will either keep coming back on while charging, or shut off and not come back on unless I force it off with Power + Vol + key. This sucks. I don't think I will get another Sony since it was so easy to kill it. Great big screen though, I will miss it.

It wasn't a sony cable though was it? can you blame sony for a defective charger that they don't make?
Sorry about the phone by the way

You're right, it was some cheap Chinese magnetic adapter, and true, I can't blame Sony for that. I guess I have gotten accustomed to buying any cheap microUSB cable or even headphone I can find, and using it on my phone without a second thought. I think that's why all of us who have messed up our phones with these bad magnetic adapters didn't stop to think we were putting our phone at risk. It was just another cheap accessory. I guess I have learned my lesson to be more careful what I stick into my next phone.
Be careful of where you purchase the dock as well; I purchased the DK 30 dock on eBay, and after about a month, started having problems charging. One day, it wouldn't charge on the dock at all.
Saw that the right pin in the dock has one of the plastic surrounds which broke off, which I assume is the culprit of the problem.
So off I went, this time Amazon, to order another dock, which works, using it now to charge my mobile phone.

Fire!
I almost killed my phone! Aside from upside-down, I was using an apple 2.4a charger - it burned the side out of the phone, and melted the cable right off the connector - in fact - the melting-off probably saved me - house filled with smoke etc. It did the mad re-start loop thing for about half an hour (my guess - there's a temp sensor in there which was tripping our because of the heat), but to my amazement, even with the side melted to death, the phone now still seems to work OK for me (probably not including the "waterproof" feature anymore).
Was super lucky it didn't burn the house down. What kind of idiot manufacturer doesn't put a polarity bridge on their reversable socket!?!?!?!

with an oem version the plug isn't reversible for all accounts I've read
I bought one on eBay allegedly SONY, broken in two-three weeks of use.
Brought another on Amazon, believe it is genuine, still works.
Both were the DK-30 charging dock. The broken one I use to watch YouTube.

Just to echo all of the previous posters - had the same issue as well.
My experience played out as follows:
* Got phone - over joyed since recently price reductions for such a high quality product meant approx USD290.
* Realise the flaps are a bit annoying so after 1 week; get magnetic charger. Seems to work at office
* Get another for home. After try two times; connect but not charge. connect in reverse. Phone shuts off immediately.
* PANICK - for next 30 minutes try the little red button, power switch + (combinations). Nothing helps
* eventually just plug into USB port and pray. After another 20 minutes get blinking red LED. But still doesn't boot
* another 20 minutes ago- solid LED; it boots! still at original percentage battery.
* now have strange problem - without anything plugged in; the phone can't boot properly, get repated SONY logo followed by power off and loop. CPU gets hot.
* If plug in USB - get styled battery icon; and when booting... IT WORKS.
* If close to fully charge (>90%) screen keeps on activating now when charging.
* to rub salt in the wound; the original magnetic charger at work doesn't seem to charge anymore (ie magnetic charger port dead).
Since it is a 3 week old phone, have lots of mixed feelings now. It was REALLY great purchase for the price and happy with it at first. but now I feel like I have a damaged product. feel quite upset.
I know buying cheap USB charger was the problem; but for SONY to have something so critical and vulnerable makes me wary as well. Initlally happy with phone (came from Galaxy Note camp) but now just wary of the phones.

I am facing the same problem. My magnetic charging port is now dead ( charging led lights up but the doesn't charged the battery. battery level goes down ). I have changed the magnetic charging port, but still behaves the same. Do you think changing the charging flex will make it work ? because if the magnetic charging port is damaged from motherboard itself, then there is no point changing the flex...
Appreciate your reply.
Thanks !
