why when you plug the phone up to charge the touchscreen goes nuts can this be fixed with a software update?
edit:wrong section please move
you are using a different charger from the one recieved from the phone or you are using some old and faulty usb port from a computer.. These problems are reported in the Apps and themes section actually the wrong place 2

Im using a cord I was provided with
Sounds like either your cord or your phone has a problem. I'd exchange them while you can.
ok it does not do this when I plug it into my room or my other PC so why does this happen when I plug it in my living room or in my laptop! Ive about had it. I hope this is fixed with a software update

There's no problem with your phone, software or hardware. The problem you are experiencing is from the usb port not providing correct voltage that the phone need. Use the cord with the provided wall charger will not give you this problem.
Same thing happened to all 4 of my touch screen phones when used with some third party chargers or low voltage usb ports.

That's pretty strange. It sounds like the circuit in your living room has more noise in the power, but usually a DC charger should reduce that enough.

DC charger?
I plugged in an eBay cheapo charger and screen's touch goes all wonky on me too.
no software can fix what is clearly a voltage issue coming from either your charger or the source that your charger is plugged into. Had the same issue last night on a walmart charger but when I use the provided usb cable in a decent usb port or the wall charger provided by samsung, the problem goes away. I would steer clear of using the problematic charger/usb cable/wall outlet to prevent possible long term damage to your device.

I noticed it happens when I have two plugs in my wall. So this is my outlet? How am I suppose to charge my device then? I REALLY want this device and do not wan't to return it because of the power issue. This didn't happen to my G1, im guessing because it used up less power?
Same thing happened to me so i took it back to BB and exchanged it. Its the phone. Go ahead and exchange it.

I have this problem came with my current touch screen and my previous blackberry storm.. I used a cheap charger and I have this problem, or even if I use my wife's Nokia also like this.. what I do is pull off the battery and reinsert and your problem will gone.. alternatively, use back the original charger.. or your case, avoid using the socket which gives u the problem like your living room..

This does not happen when I plug it into my pc can you explain that? Also I'm not going through the hassle of returning the phone again just to have the same problem occur because it is not my phone.
My transformer died... and now it won't turn on. The battery was low, so it was probably that... but I thought I charged it.
So I now think my cable is no good. the charger is for sure fine.
Does anyone know what pins to test on my transformer cable to check for voltage? it's either the cable or the transformer port itself that's broken.
before dying, the usb transfer worked. but it wouldn't charge...?
anyone know what pins could cause that?

Try to trickle charge off computer and see if it is the block. If it is then put in the freezer like Gary said. But my cable stopped working to transfer data so I had too buy a new one. So Maybe it is the cable?
Sent from my Transformer TF101 using Tapatalk
I also find that sometimes the charger goes "dumb" and you have to physically unplug the block from the outlet or surge protector and plug it back in for it to start charging again. Have you tried this? See if you can get it to charge by doing this, otherwise I second testing the USB cable portion only by connecting it to your PC and having it charge through USB although this is very slow and will take a long time. It also won't charge if you're using the tablet since USB doesn't supply enough power, it might also not charge if the tablet is on at all I believe. Just make sure it's off ad leave it on USB overnight.
I think my friend's just had the same exact problem since last week. It just suddenly stopped charging. My friend though his transformer died.
The cable won't charge but if connected to a PC, it will recognize the tablet. It will not trickle charge. I am going to RMA the cable.
Do you have a USB extension cable in series with the TF cable? The charger needs to see a gnd on pin 7 of the USB connector. If it doesn't it will only charge at 5V and it takes days to charge with the TF off. If no extension cable, plug in to a powered computer and leave TF sit for 10-20 hrs with TF off. It will charge slowly, but bring battery level back high enough that the TF charger will not think it is shorted and shut down
Thanks everyone for the help. It trickle charged, and is now at 96%.
i'll keep everyone updated.

So did the freezer trick work ?
Sent from my Nexus S
When I woke up this morning I found my tablet at 50% battery and not charging, despite being plugged in. This has never happened before and it was charging fine just yesterday. No changes have been made to the software in a good long while. I've tried three different charging cables so far.
What's stranger still is that the screen comes on when I plug it in, but it still shows battery not charging. I turned it off and left to go see a movie, then when I came back and turned it back on it had actually increased charge but only to 62%. Like it's trickle charging or something.
Anyone experienced this before?
It sounds like your charger went bad and isn't putting out the proper power anymore.

Wait, what am I throwing in the freezer and for how long? Tablet or charger?
Also make sure the charging block (where the plug is) is making a good connection where it snaps apart. Same thing happens to me when I first got mine. I put electrical tape around block to solve permanently.
Funnily enough this has just happened to me for the first time today, Ill give the freezer idea a try how long did you put in there for?
We're just putting the charging block in the freezer... right?

Left it in for 30 minutes and nothing. Screen comes on, but doesn't register as charging. The wall adapter will charge my Galaxy Nexus though...
Check inside the port on the tablet. Make sure there is no debris, and the contacts are clean. Use a toothpick or something thin to clean as necessary(preferably non conductive).

This is exactly what's happening with mine. If I turn the tablet off and leave it plugged in to the wall charger overnight it will go up a few dozen percent. And the wall charger charges my phone fine.
Let me know how flashing stock ROM goes for you please.
The charges supplies two voltages and requires taht any extension cable used be USB 3.0. The extra conductors in the USB3.0 cable ( and in the stock charging cable) are used to sense a gnd on pin 7 of the USB 3.0 configured connector. When that Gnd signal is present, the charger outputs 15V to charge the TF or dock. If you use a USB 2.0 extension cable ( extra conductors missing) or the charger does not see the gnd on pin 7 it reverts to 5V out. Your problem is that it is not seeing the gnd. on pin 7. Check the larger connector and the one on the bottom of the TF for bent or dirty pins. Your other option is to get the Dynex universal video power supply. Set the output voltage to 11V and just use USB 2.0 cables to charge. Remember not to use the dynex set to 11V to charge your cell phone or you will get smoke.
Can someone look at the port on the tablet itself and tell me if all pins should look identical? I am seeing what could be what looks like plastic debris around one of the pins toward the right. Or it could be a blocked pin used as a key to prevent plugging it in upside down. Not sure what it's supposed to look like.
I picked up a replacement wall charger today and it won't charge either. Looks like it's definitely an issue with the pins of the tablet itself. I put in a support request from Asus, but I don't know how much help they'll be. Especially if my warranty is up.
have you tried using another "asus" sync cable?
i sent my charger away for RMA as i thought it was gone (could trickle charge and pc would recognize tablet when connected - but it would not make a dent on the dock, not even the charge indicator light)......it still ended up being the sync cable at fault.
They sent me the old adaptor back with a new cable and alls well.

Yeah, I've actually tried four cables now. I had bought two extras off Ebay a while back and they were still in their bags. I tried those two, the cable the tablet came with, and a fourth one that came with the replacement wall charger I just picked up today. Between four cables and two chargers it definitely has to be the tablet at this point.
Apologies if I don’t have the right forum lads,
I bought a Pipo Max M1 tablet about 3 months ago. I loved it , a very good tablet.
I bought a second one for my nephew as a Xmas present.
Before I gave it to him I charged it using my own charger a 5V, 2.5mA charger.
Then I took it to him in Greece.
Now when I went to Greece I never took my charger with me, I assume my nephews charger would do just fine.
When both tablets were discharged I used my newphews charger. This charger was a 12V, 1.5mA charger totally different from the one which came with my tablet.
When I used the 12V, 1.5mA the tablets showed both 100% charge in 2-3 minutes and then both discharged in less than 1 minute, clearly something wrong with that charger. Both tablets never charged again and where completely drained.
Now when I came back to the UK and used my charger (which was working from the start) , my tablet will not charge, it will not turn on and the tablet will get really hot when the jack plug is located when I hook it up to the power supply.
Is it possible the tablet is fried because of the wrong charger that came with the second tablet?
Could it be a matter of taking it to a technician and fixing it?
Any ideas guys?
Thanks in advance and looking forward to your reply
I have the same problem with you. They sent me the wrong charger (9V, 2.5A). The tablet was dead after 3 minutes. Now i'm waiting to receive the right charger.

Panospc I have tried the reset button quite a few times but the batteries are completely drained!
Also I tried the method outlined in your link , although i had to cut the red cable and reconnect it but nothing happened.
My worry is that the tablet now overheats where the power supply plugs in.
Did your tablet overheat when plugged into the power supply without charging or turning on? Does it work now?
Thanks for your help by the way

I have only the 9V 2.5A charger right now, with this charger, both tablet and charger was cold all the time after 4 hours of charging. The tablet is not turning on. When I get the 5V, 2.5A charger I will inform you.
If you have a multimeter, try to measure the voltage of the battery, maybe the voltage is higher or lower than normal.

Yes I had the same issue when I was trying to get different adapters to work with the tablet.
I have ordered two seperate adapters from ebay both at 5V,2000 mA which the seller described specifically for the M1. I will post them to Greece and hopefully they will work.
Regarding my tablet as I am no expert, is it possible you think my tablet was fried?Can it come back to life?
A highest voltage adapter than 5V (the 12 V that I used) , do you think it burned the unit?

1. try to change battery.
2. unsoldered the battery from tablet and try to to relive with the correct charger ( maybe cut the cable of charger and connect the right pins to relive the battery)
3. connect tablet with the correct charger without battery to see if your table still lives.
good luck

3. connect tablet with the correct charger without battery to see if your table still lives.

I got a 5V, 2A charger from ebay and my tablet works fine now.
I guess that the tablet has a circuit before the battery that prevents charging if the voltage is higher than 5v. So I think that this circuit was fried from the 12V charger and the current doesn't reach the battery and other parts of the tablet. You have to find a way to connect the tablet to an external charged battery with the same voltage to see if the tablet is alive, I think most mobile phones have a 3.7V battery also.

Hi guys I've got the same problem. I got my PIPO m1, but it didn't switch on with or without charger. I disassembled device and charched battery straight. So, after 8 hours of charching it has just 3.25 volt. And if I connect charger to the unit, voltage on its motherboard is 0.5 volt (battery is desoldered at this moment). It can't be the problem of charger, cause I used several ones (5V, 2.5A).
And! The main point! Stock charger was from PIPO m2 so it has 9V Unfortunately, I noticed it after my first charching tryings.
For now I've got a brick. Have you got any ideas what i can do to reanimate it?? ( Thanks!

SpookyXDA I will follow panos advise today and try to connect the tablet straight to an external 3.7v battery.
Also I will try and find a 3.7v charger and connect the battery straight to that charger and see how it goes!
I have the feeling the circuit board , like panos said above, was fried at a point due to the 12V (in my case and I think the same for you since you used a 9V). If anyone is here has good imagination and creativity on how to overcome and bypass the fried portion on the circuit that would be great!
i can upload a couple of photos if that helps!

Good to hear it was a simple solution. You might check with the place you purchased it from to see if they will provide a new cable. I guess we can just be glad you didn't find out about the cable during the middle of an Odin flash...

No kidding. That would hurt a little
I am now having this problem after my phone got wet. No AC or DC chargers will work but the phone will always charge from a computer or even the USB interface of a car.
Even if I can get an AC or DC charger to be recognized, the phone will show as charging but the battery will continue to decline.
It is making no sense to me though I assume getting the phone wet partially fried something.
Yeah the voltage is increased to charge you battery when on AC power, at the kernel level. USB voltage is lower. So i'd say surely fried, and will no doubt stop working sooner or later.
I know that on my s2 I had an issue where it would say its charging and when I woke up in the morning no charge at all. The pin/row of pins or bar if you will would bend down and not make good contact. I used a tooth pick to pry up on it every time it did that.

Thanks. I didn't realize that the charging port was removable on the S4 so I swapped that out and all is fine now. :good:
Ummm... No its not the voltage. It is the ID pin. The voltage stays the same. The only actual difference is the milliamp mAH output of the charger. A normal USB plug has 500mA our charger has 2000. How the phone tells the difference? The 2 data pins inside he charger are shorted together. The voltage always stays the same.
