[Q] Dock will not charge

My TF pad charges just fine, so there is not any problem with the charger. However, the dock does not charge at all. Even after 12 hours plugged into the wall with the unit turned off, the orange light is still flashing when I boot up. This might be a problem with the firmware. I am running:
HRI66.US_epad-8.2.3.13-20110511
I read somewhere that I should reflash the firmware. I have downloaded this version of the firmware onto a USB drive and the TF recognizes it but will not open the zip file.
What are the steps required to reinstall this firmware? Does anyone know of any other ways to fix the charging problem? The ASUS support site is nearly worthless. I humbly apologize in advance for my ignorance and thank anyone who responds.

that is the Build Number, and mine is the same and I updated everything correctly so it looks like you have the most updated version.
My MobileDock version is EP101-0209
It might be an issue with the dock charger, a hardware issue, the battery may have stopped working, we never know...
if it's a firmware issue, give Asus CS a call and ask them what to do next or how to properly install it.

Does anyone have any other suggestions? My keyboard has stopped charging as well.

Same for me unfortunately

I had the same issue and had to unplug and wait, switched outlets and it's fine now.
There is definetely something wrong.

Maybe it's designed to fully charge the tablet first then start topping off the dock.

I had the same issue - constant flashing orange led no matter what configuration I tried.. TF docked, TF not docked, TF docked powered on, TF docked power off, change outlets, let it sit for hours and hours (over 24 at one point) etc etc
Nothing worked.
And like yours, my TF always charged - whether docked or not.
Called Asus - w/o even asking any questions they just directed me to the RMA dept.
Instead I just returned it to Amazon and then waited until I could order another one. It took nearly a week, but they finally came back in stock on Amazon (for an hour) and I ordered another.
It should be here Wednesday, so by then I'll know FOR SURE whether it was the first dock that was bad - or if it's my charger / cable.
I'll post back once the new one gets here..

My keyboard is waiting for UPS pickup for a Newegg RMA. The keyboard is deactivated at Newegg now. I'm wondering if they will wait for more stock or give me a refund. I'm just glad I still have the tablet.
Does anyone know how widespread the dock charging problem is, and if newer units have any changes to fix this?

The docks were scarce here in Taiwan, still are. That must be an indication something is rotten in Denmark and Asus knows and are working on it.

Updating from my earlier post: My new keyboard / dock arrived yesterday. When I plugged it in, the LED was solid orange (ironically, this LED looks a lot more "red" whereas on my other dock it was definitely "orange").
I charged it for 8 hours and the LED turned green during the charging time.
So at this point I can definitely say that it was the dock that went bad and would not charge - as opposed to the charger being bad.
I would advise just returning your dock to the place of purchase if it's no longer charging.

Be interesting to see if those having charging problems with the dock have an orange or red led. I have had no issues, but my led definitely looks red. When the charger is charging, it gets very warm (hot). If your dock has been plugged into the charger for more than 20 mins and the charger is not very warm, it probably isn't charging.

Just wanted to update my previous post (2 up) because now my second dock is dead.
Under normal usage everything would worked fine - the battery would drain and then charge - no problems at all.
HOWEVER - There appears to be BIG problem with these docks and I feel this is what is causing (or contributing to) my docks dying. These things have a constant drain on them when the Transformer tablet is attached - even if you power the tablet OFF.
http://forum.xda-developers.com/showthread.php?t=1112835
I believe what is happening in my case is that the dock battery drains to a point where it will no longer accept a charge. In both cases, I had the tablet docked to the keyboard - powered OFF - and did not use it for a week or so. When I went to power it on, the tablet/dock had just enough juice to tell me that the battery was very low (I believe around 1%) and that it needed to be charged - and then it shut down.
OK, fine, no problem. I plugged it in to charge and left it.
The tablet charged up to 100% with no issues, however 72 hours later and again I have a keyboard dock with a constant blinking orange LED that will not charge. Again, I tried charging it with the tablet attached and without - no change. The adapter doesn't even heat up when trying to charge which again tells me that something in the battery on the dock is not accepting the charge.
Looks like this one will be going back to Amazon as well. I'll also contact Asus regarding the issue and will report back what I hear.

Hello,
I Have the same behaviour,everything were fine until I unplug the dock during several days and the charge was down at 0%.
Now, I 'm unable to charge the dock with or without the tablet plugged
I hope that it's only a firmware issue.....................

Sorry to hear it, but thanks for letting us know.
I have a bad feeling that this is an issue that is going to end up biting MANY users after their return period has expired. It seems that the huge majority of TF owners use their tablets / docks nearly every day - if not daily - so they won't run into this problem.
I'm concerned that after a month or so and some of the excitement has worn off, and they put their TF/dock away for several days suddenly their dock will be rendered useless (at least as far as the extra battery goes).
I've just sent a note off to Asus (per their request from my Amazon review) and I'll let you know what I hear back.

OK
thanks you for your action !! and to keep us informed.
For me, a lot of people are concerned ..... as you said...

i have same question too

My dock has same problem, have tried with or without tablet recharging, the led of dock is always blinking red when tablet connected, and dual battery widiget always display it's discharging and slow draining from 40% to 35% now.

In order to consolidate and try to keep this issue in one thread, I'll only be updating this thread going forward: http://forum.xda-developers.com/showthread.php?t=1112835
I just added my latest correspondence with Asus on the matter, but unfortunately it doesn't look like I'm really getting through to anyone of quality over there..

gents,
just wanted to add my possible fix for this issue.
I had this probem and my dock would not charge. Somehow i got it working again. Here are the steps i took, not sure what fixed it in the end but you could try and replicate and see how you get on.
1. I went to charge my keyboard on its own. I left it charging for hours and it was still flashing red.
2. docked the keyboard and the power widgets showed no juice within the dock althought it worked as a keyboard.
3. I plugged the power in the dock while docked and on. It showed that it was charging the tablet but not the dock. The dock stayed at 0%.
4. I left the two charging while on for a few hours. The tablet was now showing as charged but nothing still in the dock. I then shut down the device with a turn off but left the power and the dock in. As i shut down the light on the side went to solid red and stayed solid red while the device was off.
5. I left the device off but with the charger in the docked keyboard for about 10 minutes. I then turned the device on while docked and still charging. When the device turned on the battery widgets showed the dock with 35% charge. i left the device alone for a while on and dokced and charging and after about 10 minutes the dock charge started going up. I left the dock charge while the on the tablet was on and docked until the dock was charged to 100%. I then turned the tablet off. took the charger out and undocked. Turned the tablet on while on its own. Then docked it with the dock with no charger in and da daaar the keyboard showed 100% charge and was working......yea!

This is what I figured out, not sure if it's actually true but whenever I did some huge data transfer from the datacable computer --> tablet afterwards it wouldn't charge... so I had to leave it unplugged for over 6 hours adapater and cable, then tried again and it works... still going to go visit the local asus warranty center sigh.

[Q] TF battery no longer charging. Any suggestions?

It looks like the battery on my TF is refusing to charge. Started all of a sudden last night. I tried to turn it on and it didn't come on even though I didn't use it much,so I figured the battery may have drained somehow. I plugged the charger and sure enough I was able to boot the transformer but the battery is not charging and it displays an exclamation mark on the battery icon. It is showing 0% charge for over a day now even though I had it plugged in all this time. I tried turning it off and keeping it on but it doesn't make any difference and it doesn't charge. I tried full factory reset but it didn't help. The exclamation point stays on the battery icon and it is not charging. It works when plugged in but shut off as soon as I unplug. I don't think it is the charger because the same charger charges the dock just fine. So I am afraid that it must be the tablet issue. Any suggestions before I start the RMA process? Thanks.

That's weird. Mine started doing the same thing in the last day as well. Won't charge either when plugged in via the dock or the tablet.
Anyone got any ideas?
Edit to add: Ah, got it working. Seems that unplugging the adaptor and waiting half an hour seems to reset some trip or other. Odd, because it doesn't seem too hot when I leave it plugged in.

Good for you... unfortunately this trick doesn't work for mine. Had it unplugged fo hours, plugged it back in and same thing. The dock charges fine so I don't think it is an adapter. The TF is not charging if plugged in or docked on the kb. Tried to take off adapter prongs and re-seat it and still same problem. Adapter doesn't seem hot at all.

I had a question mark as well. I ended up sending it in. It did happen right after the battery was very low and I tried to turn it on, while the adapter for some reason was not connecting (it happens every now and then that mine does not connect). So I think it had something to do with that - battery got too low.
In addition the tablet was no longer recognizing the dock - it would just show the question mark and the dock did not work.
Anyway, I sent mine in, and requested they address the battery drain issue (which at that point was just announced in the Asus Facebook UK page). Came back fixed ... first the tablet - and they found no problem with it, then the dock about a week or little more later - cambe back working with no battery drain issue.

Thanks for the response, not sure if you had a typo or if you had something different. I actually have an exclamation point (!) not a question mark on mine. Just called ASUS support to get an RMA. Was on hold for close to 40 minutes until someone finally picked up. The guy was like a robot, but I guess it was expected. Told him about charging issue with TF and about my dock not switching to battery saving mode (I have one of the first models) and he said to send both in for repairs. I asked if I should use the original packaging he said I was responsible for packaging. I said I understand that and if I use the original boxes from TF and dock, will I get them back? He said no... I guess I will just have to wrap them well and use other boxes. I am wondering how others sent them and if you got your original boxes back. I mean it has serial number and other numbers on it that I may need.

TF700 won't start up, DOA? Please help.

So, received my TF700T in the post today. Got all excited, went to start it up, and nothing....
Has been on charge for 3 hours now, and I still get nothing when trying to start it up.
The orange light near the power button is on, indicating the battery is charging, but no matter what I do, whether I hold the volume down with power, hold both volume buttons and power, it won't start up / boot.
The strange thing is, when I first tried to start it up, it wouldn't load, so I plugged it into power, and I got the ASUS post screen, then it turned off almost immediately (I presume as it had insufficient power). Since then, I have not even been able to get the ASUS post screen. If I hold the power button for 10 seconds, it will vibrate after 10 seconds, then nothing happens.
I have tried all the volume + power buttons described above, as well as trying to reset button.
Is the tablet DOA? Any suggestions for ways I might be able to get it started?

Try putting a pin in the pin hole above the HDMI.

Tried this already, and just tried again now. Nothing!
Its weird that if I hold the power button in for at least 10 seconds, at about the 10 second mark, the tablet vibrates, but nothing happens.
The charger light is now green on the tablet, and still nothing. Has been on charge for 5.5 hours now.

Unfortunately, It sounds like a DOA. It happens. Good to know now then 6 months down the road.

Exchange it.

Haha, good old DOA. Mine took 6 weeks and the store gave up and just gave me store credit.

Return it!
I had exactly the same: on first boot it turned off after splash logo and I needed to use reset button to restart again.
long pressing just makes it vibrate but nothing more
And when it started, it crashed and rebooted all the time. Sometimes it went black and I had to reset it again
My replacement works perfectly, so yes it's a semy-DOA

Thanks for the replies all, I'll send it off this morning and update once I hear back from the seller (the joys of international dealings).

Mine bricked with the same exact symptoms after a week. Worked flawlessly up to that point. Waiting on the replacement to ship...

hi,
I was gonna open a new thread since my problem is based on charging but this thread pretty much is for the same use.
I got my tf700t yesterday through a friend visit from US. It has been nearly 2 weeks since he got it and he never charged the tab since he wasn't much of a user. So yesterday he brought it to me (i'm in TURKEY btw) and the tab was working pretty properly. But it's charge was near %4 so i plugged it on to its dock and plugged the usb charger to the dock via my PC. I just saw on the tabs screen that its charging so i left it there for like 12 hrs since it was its first charge. Then after nearly 12 hrs later this morning, i disconnected the charger and saw that the tab was off. I tried to turn it on but just like cjhod1 says, I got the ASUS post screen, then it turned off almost immediately. Different then cjhod1's case, no matter i plug on the charger or not my battery led near the power button is off for all times. So i guess this means it doesnt charge at all which was operating properly 12 hrs ago.
Strangest thing is my dock doesnt charge either. I tried every possible combination but couldn't manage to get it done. Even more strangely, after a one hour charging with nothing indicating it's actually charging (the orange battery led is off for all times) it managed to get a %1 of battery charge and opened. It managed to stay on for 10 seconds and then shut down once more for all.
It seems like a battery problem but what are the odds to lose both dock's and the tab's battery after one charge. And now that i'm in Turkey, and as far as i know, asus doesn't provide an international gurantee but only for US, i can't seem to get any service here. Unless any solutions to this matter occurs, i will have to ship it to the seller that i got from the Amazon. Every suggestions or helps appreciated. Thanks in advance.

The tablet CANNOT be charged via a USB port! Use the specific charger that came with the tablet. This will deliver the necessary 15V to the system to allow it to charge.

then how come i managed to charge it the first time i plugged it to the PC? And even if so, that is not any handy at all. I will have to carry not only the usb cable but also the adapter with me for all times to be able to charge the tablet. That is not an issue for ipad as far as i know.

It's not a big deal. It charges to full within 2 to 3 hours. Put the darn usb and adapter in your bag pack along with your tablet. It's not like it's a size of a water bottle or something. Charging through the usb is not ideal since it trickle charges and will take forever. Charge it through normal means first and see if it can hold a charge through your everyday use. If it does then your good to go. Then try charging again through pc. Honestly with the tablet keyboard combo you won't have to worry about not having enough battery life to last you the whole day regardless of what you use it for.

Hi Bezendra, did you get it to work? I have the same problem. I'm in Vietnam, and whilst the tablet charges just fine, the dock seems totally Dead on Arrival and doesn't charge (no light, nothing). Warranty isn't really an option here so I need to troubleshoot this exhaustively before giving up. Did you discover the problem?
Speculation: I remember a friend who visited here once, and their externally powered USB hard drive didn't work in certain houses. I think it depended on the type of voltage regulator in the house. Did you discover anything similar?

<Help> Dock not charging

Tried the following methods=
Cold boot
Switching from PC USB to Asus charger
Switching from other manufacturer's charger to Asus
Freeze the charger(???)
Adaptor charge the tablet in good order, but it doesn't seem to be charging the doc.
The dock is always blinking rapid amber led when plugged in and the adaptor just get really hot.
Guys, any advise? Warranty expired, it gonna hurt my wallet to send in for repair ;(

If you let the dock drain 100% it sometimes encounters problems. If you open up the dock you will see a little switch. Flip it back and forth and it should start charging again

Got the same problem as the OP - Dock not charging and even the dock option is greyed out within the Settings - Interface - Launcher option.
My question is - Is there any software command that would simulate the flipping of the switch using ADB etc? Would not want to open the dock as yet..
It works properly when I attach it to the tablet, only problem is that it doesn't charge...Any pointers would be more than welcome!
Am on 4.1.2, CM10 2012 12 08 Unofficial
Thanks!

Try a cold boot, it fixes lots of these problems. Hold the power and vol down buttons till you see 2 icons on the screen, then release the 2 buttons and let it boot. Try it while docked and it should start charging again.

Yes, already tried that (it says cold booting linux and all..) , I tried it while docked and with the charger in the dock..but still the same orange blinking light..Dual Battery Widget also doesnt detect the dock..though I can type with the keyboard and all that stuff..

Guess you should open it up then, and try to switch trick as I doubt there's an ADB command for a hardware switch inside a "third party device" since it's not part of android but really an extension that probably requires drivers and/or kernel modules outside of stock android. If there is, it's probable it's not documented if it was added by Asus for Asus. While it's opened up inspect the battery for obvious signs of wear/damage. Dual battery widget didn't work for me on some ROMs (can't remember which exactly but only the tablet battery was detected) but recent CM10 should have a separate icon with a dock through the battery icon while docked.
You can try the dumpsys utility from ADB, which prints out battery info so you may find something, but you can't manipulate data at all:
adb shell dumpsys battery
Also, did you try wiping the battery stats in recovery? If you have that option...
And lastly, lots of people are suggesting the freezer trick. To me that would be last resort but it looks like it's working for some people it seems.

Thanks for your detailed analysis and useful suggestions - just reflashed the CM10 8th Dec UNofficial rom y'day only and then recovered all the apps etc..But your idea of wiping out the battery stats didn't cross my mind! Should be there under advance I guess within recovery..(Have touch based 5.9 or something)
I would let the charger plugged into the dock and then try again the cold boot trick to see if that resolves the issue..Else would see if I have the option of wiping battery stats within recovery..
I am currently on vacation and hence donot want to open up the Dock here, freezer trick while harmless but I fail to understand logically how that would help Nevertheless would try it out if the above doesnt work..
Would report on the updates tomorrow (after 12 hours or so.)

The freezer trick is an oldie but a goldie. I used to do it with old hard disks that had certain problems and it worked in some cases, but usually you had an hour or so to salvage the data then it would die for good...
The logic behind it is that cold contracts the parts while heat expands them. So if it's a bad solder or something alike, the cold can temporarily fix it. But as I said, it would be a last resort for me and I'd triple seal it in ziplock bags to make sure no humidity can get in or out.
Let us know how it works out!

I am actually inclined to open up the keyboard and flip the damn switch now!
Also I did try cold booting (as the tablet had charged to 98%) and also wiping out the battery stats, but no change in situation still.

Opened the keyboard, flipped the switch but still no change..Orange light just keeps on blinking approximately every second..
Am at a loss to understand what could be the problem - the dock and tablet were bought in Sep last year and the dock has hardly been used (probably not for more than 20-30 hours in the last 14 months or so..)
Anyway I havenot closed the keyboard completely, would flip the switch again after sometime and see if that changes the charging behaviour in any way!
Anyone who has had success with dock charging issue after flipping the switch?

Update on previous post - Suspecting that it could be a software issue as well, I flashed an old Megatron Rom (based on CM9), and tested the switch again.
Switch off - Only EeePad's battery is shown
Switch On but no charger - Dock's battery is shown (symbol of battery + Keyboard) BUT with a red exclamatory sign, along with the normal EeePad's battery
Switch On and with Charger - Dock's battery is shown (symbol of battery + Keyboard) with charging sign , along with the normal EeePad's battery
So definitely an improvement as compared to CM10!!
Wondering if I should search for a Stock (Rooted ?) Firmware and flash that..Or probably just a firmware for the dock (does that exist?)

I'm pretty sure there is firmware for the dock (I think you see it in the settings while docked) but I don't think it's available, nor does any rom actually change it they just "use" it. For sure the best thing to try would be stock now with dual battery to make sure it works properly. Easy flasher will get you back to stock, provides root and can install different recoveries for you (there's plenty of others but this one seems easiest and worked best for me).
I'm thinking you're right on both accounts: the switch did work and there's a software issue somehow causing this. I've seen stranger things with custom roms. Glad you're making progress!

Thanks a bunch Lethe6 !! I have downloaded the Easy Flasher (V 0.8.3 Stable) and am downloading the Stock Rom from ASUS WebSite (300MB)..Its a slow connection here, so I would be able to report back by tomorrow only..But I am optimistic that Stock Rom should resolve the issue with the charging!!
Thanks once again for providing the links, I would report back tomorrow on the progress!

UPDATE on prev post - Flashed the latest stock from ASUS Website ..It does show the Dock Battery BUT at 0%
And from what I read here, I seem to have run out of lack as apparently there is a design flaw wherein there is no way a dead battery can be revived!!
(I ran out of warranty in September but as I wasn't using the dock really at that time, I didn't bother to look into the issue at that time..)

That really sucks But it must be a particular model because mine has went to 0% numerous times and I've never had that issue before. Did you try the freezer trick? At this point if it's supposedly completely dead, might as well give it a shot. Also some people suggest plugging it into USB for 5-12 hours, the trickle charge may help getting it going again. If the tablet is not 100% charged the dock won't start to charge either, so try just with the dock then try with both. Also check this out, sometimes strange fixes are the best.
You can probably find a refurbished dock for under 100$ during the holidays online, if you really need it.

Out of curiosity which series dock do you have? Mine is a B70 purchased in UK last September..(Tablet is also having a S/N starting with B70 and SBK v2)..
I tried the other fix as well that you mentioned - that is using a different USB charger, to my surprise without the tablet attached, there was no light on the dock. but if I attached the tablet, then orange light was blinking much quicker! So seems like the dock is quite sensitive wrt the current supplied through the USB cable..(Guess all USB chargers have typically 5V output or something?)
On using the original ASUS USB Charger, light blinks slower (with or without the tablet attached)..Have left the charger plugged in again ..in the faint hope that some trickle charge is able to revive the dock's battery!
And no, haven't tried the freezer trick as yet
Would probably contact ASUS UK once I am back in UK..

My "mobile dock" version (you can see it in settings -> about tablet -> mobiledock) is EP101-0213 and my tablet is SBKv2 C30 purchased in Canada 6 months ago.
There's a nice article explaining voltages and amps in relation with phones (which applies to almost any mobile device), however from what I read, the Asus wall charger has a different pinout for USB and feeds the power differently. I'm sure you can find the exact specs here somewhere, I saw people showing how to make your own charger.
But assuming you're right and it's sensitive to the current (Bad design? Cheap parts?) then it's possible that simply replacing the wall charger would solve it. I bought a spare one to leave at work for 8$ on ebay and it works nicely so far!
Just out of curiosity.. did you/can you try to connect it to another power source? Like a different house? I once had a problem with a charger that there was too much noise on the electrical system and the charger couldn't keep a decent current output because of the variations, so the phone would say it was charging but it wasn't; tested later at several locations and it was working. I know it's a long shot but hey at this point...

Thanks! Would have a look at the link you provided..Meanwhile I also came across this link which kind of indicates that using a 12V 1A charger fixes the dead battery! Would probably order the relevant stuff from ebay and see how it pans out! Just crossing my fingers at this point really and have also left the charger plugged in to see if it does trickle some charger into the dock!
After flashing the latest stock rom (instead of CM9 or CM10), I also have same version for my dock ending in 213..
Finally apparently it seems that USB Debugging off/on also seems to affect the dock's battery as per the various other charging related threads on XDA..
Thanks for all your suggestions - you keep me motivated to try out various things and I am learning new things as well !
PS : Forgot to mention that I had already tried a different power outlet (i.e. in UK) and now another one in a totally diff country!

Can't charge after updating to JB

Hello,
This is the first time I am using Android so please understand that I know basically nothing about it.
So I received a refurbished note 10.1 (software 4.0.4) with about 50% of battery left. I played with it like 3 hours and then updated to 4.1.1 (or 4.1.2), battery went down to like 10% so I plugged the charger in and kept playing. After further 30mins I realised my battery still goes down (8%). I had a quick look in Google and many people are saying that after updating to JB tablet takes very long time to charge or doesn't charge at all. I thought mine will charge slowly so I left it overnight plugged in. I woke up with 7%...
I tried charging it with a USB cable connected to a TV, in the first hour it charged to 8 and after that (about 3h) it stayed the same.
So the question is: Is it the charger, software or is it just a faulty tablet?
What I would like to try is to downgrade it back to 4.0.4 but I am not sure how to do that (or if it is safe) with such low battery level. Is it possible to downgrade when tablet is off?
Thank you

Factory reset or reflash the firmware JB you flashed .
But i would return to the seller has you have no evidence JB is the problem as you only had the tablet 3 hours .
Flash any firmware via Odin min requirements 30% battery to be safe .

Have you tried charging from an actual power outlet I don't believe that you can charge them via tv, pc or any other device only via an actual power outlet.
As far as roling it back to ics I believe you would have to flash it but don't take my advice on that one, maybe someone else could advise?
Also no I would upgrade or down grade firmware without a fully charged battery.
I found that mine was charging worse after jb update I actually factory reset it and its a tiny bit better, I still find though that if I want to charge it fast its best to turn it off and let it charge, I also noticed that the biggest culprit for draining the battery atleast on my device is Skype just having it running in the background drains it heaps.

Yeah.. but what if I can't charge it?
Can I factory reset (I believe that's via recovery mode?) when battery is almost dead?

I left it charging the whole night using the included charger (It looks like an original one) and as I said it only dropped by 1% (tablet was off the whole process)
From what I know it does charge through TV's and stuff but it just is a lot slower.
And I have no apps running, wifi off, gps off - everything off. RAM cleared
// After about 3 hours of charging through a TV it went up by 1%...
I left it charging through a TV because if a normal AC didn't help I thought it may be something to do with the charger.

Factory reset is in settings under personal heading its the backup/reset tab obviously make sure you back up your stuff first or you will loose it, this won't role it back to ics but might help. Also I have never found that any of my android devices charge via another Device only wall outlet they do maintain the power level there at but don't really charge.
Do you have another ac adapter I youncould use to test with try a different ac adapter if possible.

charging cable likely cause
I have had very bad luck with factor Samsung cables.. I would Use a different usb cable and wall plug usb brick.. make sure its output is equal to or above the original Samsung charger .
This is likely why the device was returned to begin with. As most of us know refurb devices are usually just open box customer returns. Often are just factory reset and resold .

oh, I forgot to mention, I have tried this because I thought it will go back to ics.
I dont have any other adapters, as I said this is the first time Im working with Android.
But, my friend has Galaxy S3, will that work?

It might work check the voltage to see if its the same and use your usb cable, they use mini usb I believe. Thats the other thing the usb cable that you using might be stuffed. The cable on galaxy tab 7 looks 100% but it doesnt work at all, as erica_renee said samsung chargers aren't the greatest.
I use a Belkin charger much stronger than samsung original

From what I've read, one review says that there is no way to use a S3 charger. + it has 1A
Apparently note uses different pin configurations..
I have no idea what to do now... :<
What about finding a galaxy tab charger?

Galaxy tab charger will work I have and I just use it for both without any problems, you could go to tandy electronics or radio shack depending on what country your in they might have somethingcheap that might work or the might be able to test the one your got to see if its actually working

Right, before I get one, at the moment Im trying to use iPhone charger with the standard samsung cable. I showed a red cross (what I would expect it to show). I then tried to hold the volume up while plugging it in (Ive read on one forum that it helps, not sure what it does but worth trying) and it jumped up by 1% - no red cross now... I have no idea what Im doing or why no red cross is visible.. ehh
//edit:
Guys.. this is working!
Another 1% in 15 mins.. It may not be much but believe me, Ive been waiting for that 1% for a long time
I'll give an update soon
//
Further 15-20 mins and it increased by 2%. Well, yay! I guess

Not good where did you get it, does it have warranty make em fix it and give you another charger

Hi all,
last night my n8000 stop charging. ..
I even tried the different chargers and also tried to charge thru pc...
When I connect with charger the beep sound come but nothing more and cross sign appears on battery icon.. and worst of all my n8000 not even recognized by pc even...
Any idea ?
EDIT : changed the cable and everything returns to normal

Yes, return under warranty... This is not right. It sounds like the usb connector might have a problem...
