Almost certainly bad hardware. My first i9000 had a problem with charging, so they just swapped it for another.
Take it in and try another.
i am not really into it and it could be absolutely nonsense xD sry if so
could it be that your charger is only for ~220-240V and you are trying to charge it in a country with ~110V

i have usb way to charge it>>no diffrents!
I have a plugin charger & a USB charger. When I plug my USB charger, it charges quite fast. But with the wall charger, there seems to be a problem. I discovered that my daughter had tried to push it in the wrong way & has bent the pins way too little. Now, when I have to use the wall charger, I need to shift the phone a few times for it to connect. Is it possible to bend the pins INSIDE your phone socket? Is that why it isn't connecting properly?
always the phone is showing charging so no way for desconnectiing the charger or the pin inside
Don't know if this is your problem but the charger that came with my phone was very slow, it would take about 6 hours to do a full charge. I bought one off the internet designed for a blackberry and it charges my phone in 2 hours now.
When I plug my charger into mt KF, yellow light comes but it doesn't always charge . I don't understand why light would be on but not charge.. Any ideas, Thanks..
Check your charger
I had a similar issue with my Fire. By chance are you using a different charger than what came with the device?
I found that using my phone's micro-USB charger didn't produce the necessary amperage to charge the Fire. The light would light but it never switched to charging mode.
If your charger puts out less than "1.8A" (it's written on the power brick) that could be the reason it's not charging.
Hope that at least helps narrow down the issue. It could still be your device but hopefully this is it and it's a quick fix

I had this issue too. Best advice I can give you is to go get you a new charger. Any micro usb charger will work, just make sure that you get the 2A or above output.
Hope that helps.

I was having the same problem and thought it was the port but it's actually the cables. The prongs on the micro-USB cables that secure it in the port are rooted in the base of the plug. Bending the metal plug back to its original flat position will put the prongs in a more exposed position providing a more secure fit. Bending it past horizontal will expose them even more. I found that an up angle micro-USB cable fits in in an orientation that causes less stress on the plug and prevents this problem from reoccurring.

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.

Put it in a zip lock bag and throw it in the freezer, take it out and try to use it again. The thermal overload may not have reset itself, this has happened to myself and others a lot.

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?

Yeah dude have a read of this : http://www.transformerforums.com/fo...ide-so-your-transformer-wont-charge-boot.html
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).

Ive cleaned all the connectors, the strange thing is the ac power seems to be trickle charging it just as a usb port would.
Put charging into frozen and leave it 10-20 mins
Takeout and wait until it dry
It'll be work now. I'm used to be using this method

Me and the OP have tried that, and no hope, charges my phone fine, but trickle charges the tf (Might not be charging at all but the screen flashes on when first connecting)
Im on a Ubuntu / Revolver 4 dual boot so im gonna do a re-flash and bring everything back to stock and see how that goes

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.
Try to reset your tablet from the small hole in the back side. otherwise, you can try this http://www.slatedroid.com/topic/38865-dead-pipo/page__st__20__p__471674#entry471674

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?
Thanks again ( PS: I think you are Greek?)

maybe this suggestion will be work but i am not for sure.
i will take no reponsibilities of damages!
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

are you saying straight connection of the two battery cables to the power supply? will this not damage the battery even further? my charger is a 5V and the battery on top it says 3.7 V?
3. connect tablet with the correct charger without battery to see if your table still lives.
tried it no luck!
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.

panos good to know your unit is working fine!
there are three cables when I open the tablet
1 red
1 black
1 grey
what's this grey cable doing? According to your advise, should I connect the red and black cables to an external 3.7V battery?
I read in a couple of forums that I can jump start the battery...how is this possible? any instructions/procedure?

Yes, Make sure you connect it with the correct polarity, red wire is positive and black wire is negative.

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!
I will wait for your results!

Iam afraid none of the things i tried works...i need to find replacement parts if this is going to work..i think a small section of the circuit board if fried.
When the rablet is plugged into the power supply it gets very warm which means electeicity goes through but i doesnt reach the battery
Any idea where to get replacement parts guys??

Have not had this problem myself. Try another USB charger? Just about anything that's 500mA will work (albeit not nearly as fast as the 2.0 amp charger that came with your phone).

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.
