I am having an issue similar to another user.There is a question mark in my battery indicator and the only way it turns on is when I have it plugged in. The other user opened up his G tablet and unplugged the power supply then plugged it back in. Can somebody let me know exactly where they cord I have to unplug is? Thanks.
I know there is a breakdown of the hardware here:
http://forum.xda-developers.com/showthread.php?t=842354
But I've got it open and I just need someone to tell me exactly what I need to unplug.
Did you ever figure this out? I'm assuming it's the jack with multi-colored wires coming out of the battery, but unplugging/plugging this back up didn't fix my problem.
is is the multicolored wire that was talked about. I have never heard of this fixing this problem though. What I would try is to completely drain your battery. Then charge it fully all the way till the light turns green. Then open up CWM and go into the advanced settings. Click on reset battery status or something to that extent. Make sure the tablet is unplugged. Hopefully it will fix your battery stats.
I dunno about Dirty Bird, but mine won't run without being plugged into the charger. So there is no way to discharge the battery.
When I plug the charger into the G-tablet, the LED which is supposed to show green or red doesn't light up at all.
I am really disgusted about this - especially now that I've opened the case. Grrr.
But, thanks for trying to help anyway.
this is the power supply form the battery.
Thank you. I had the right thing.
I am now reading over some threads about the power connector - I reckon it's possible that it is disconnected, although if the tablet is getting power through it, it seems to me that the battery should be getting power for recharging as well. But I am certainly no expert!
Edit: Checked the connector and it seems to be okay, firmly connected to the board and the solder looks okay to me. :/

It seems my power adaptor has died..
I have been using it daily with no problem, and charged it over night last night.
I got a new stand today and moved the power supply to a new location, shifting the transformer with the adaptor still plugged in.
From that point on, no charging...
the cable is good cos it still shows up on the PC, although I guess it could be partially broken.
I have tried leaving the power adaptor unplugged for an hour or so, but no luck.
Anyone else have suggestions?
Is it possible that you bent a pin in the slot on the pad that you plug the charger into? Alternatively, you could take apart and reseat the 2 pieces
of the charger itself.
Pins in the pad seem fine, same on the charger.
I just turned it off to see if I could get it to charge from a USB hub on my PC, but it seems not.
This points to the cable being at fault, but with no replacements available I am still stuck with a discharging tablet.
Very Frustrating... I guess I will be Calling Asus support on Monday.
Its a shame Comet is out of stock locally, or I would walk into store for an exchange

charging thru a PC usb hub is slow...the ac adapter is rated at 15v 1.2a...and a PC hub is only 5v .5a i think...
Anyone know what the adapters for the other tablets are rated at?

I realise its slow, but I would expect SOMETHING after leaving the TF plugged in for almost an hour turned off!
This might sound ridiculous but unplug the usb cable from the power brick, unplug the power brick from the wall, set them aside....then wait a while (20+ minutes), then come back to it and try to plug it back in.
I had this same exact problem but I did the steps I told you and it began charging again. I'm not sure how or why though.

I left it for a while, but I shall try again.

Plugging in the PSU normally turns the tablet on, and currently it isnt doing that.

What is your battery percentage at? Anything above 90, and it won't charge until it drops below. Kind of a built in failsafe.

Ah yes, it is above 90%, but I am sure it would show the charging icon?
I can only hope this is a false alarm, I will be less annoyed then..
Nope, won't show the charging icon. What I've done, if you want to ease the paranoia, lol, is hold the power button down and keep holding until the device shuts off completely. (do this with the plug disconnected) .. Now, plug the charger back in to the device. The device should power on, and you should boot up to a charging icon.
If it doesn't start up, then yeah, you may have a faulty charger. Let me know how it goes.

Worth a try, but no, nothing...
Then just let it run down passed 90% (like 88-89%) and see if it charges. If not, then yeah, sorry.

No it does seem to be the PSU, I have used my Desire charger to charge the TF overnight, and got it back to 100%

It does on mine.
Little tip for you all... don't leave it charging overnight. It may be a bit late advice for some, but for others it might help them ending up with a useless power adapter. Unplug it when it gets to 100%. Get an app that alerts you with a sound, signaling when the battery is full. Battery monitor widget does this. Also unplug it soon after its done charging. This is assuming you don't care about battery life of course.
If you DO care about it then charging it up to 100% all the time isn't a good way to keep your battery healthy in the first place. Loads of guides on the web for Lithium Ion battery care.
There's obviously a problem with the adapter design, due to the amount of threads talking about this very issue, when people leave them charging all night. Maybe they are overheating, or some other reason. Prevention is better than cure.

Over heating might well be the issue, I am getting that sweet smell of cooked circuit board from the PSU.
Not meaning it to charge over night will be annoying, I like things ready to go come the AM

Yeah I agree it shouldnt happen. Just saying I think it is. Pretty sure there are guidelines and safety features that are applied to all power supplies to make them safe for use in the home, at least there are in the EU, and it seems these ones are in violation of those guidelines, even though they have the CE approved label. If you are smelling something burning/melting its obviously faulty and needs to be replaced.
Well I tried comet for the warrenty and was directed to the asus support line, which is closed today.
How dull.

Is using the Desire charger just as slow at using a normal (5V) USB hub?
I'm no engineer but aren't there safeguards built into a charger/battery that is operating normally? ie: put TF on charger overnight, battery draws power till full then stops charging?
I use my TF all day, at night it goes on the charger, at no time does my charger get "hot" to the touch.

Ok so I was at work listening to music when my phone froze. Pulled the battery, which was only at about 85%, and tried to restart. And, nothing. No green light, no dual core screen. Tried four different chargers, including OEM Motorola charger, and tried hooking up to my home PC. Only thing that happens is when I hook up to the PC without the battery in the green light comes on. Power button still doesn't turn the phone on. Just turns off the light. I tried to search, but the closest I found was people stuck at the dual core screen or people who didn't realise their batteries were dead. If it helps, I'm unlocked, rooted, and running GingerMod 2.3.6. Any help is appreciated! Thanks!
Sam issue
I am having the same issue with my wife's phone. We both have Atrixes and I have tried swapping batteries and her battery works fine in my phone. I still can't get it to start up. No green light when plugged into the charger but a solid green when plugged into usb on my PC. How did you end up solving your issue?
I got this problem once. To fix, pull battery out, plug in wall charger to phone (without battery), should boot to the battery with question mark icon, plug battery back in.
I work at a cell phone repair store , and from reading your symptoms I think you might have an issue with the flex cable running your LCD. In the atrix if you drop it there is a possibility of shaking the flex cable off your board, and its a matter of micro soldering or just connecting the cable. I DO NOT suggest doing it yourself. If you want it done professionally call my work. 6053350411

I solved this problem with wall charger
Will anyone here elaborate how to fix it again?
If I plug it in wall charger, no response and no light.
If I plug it in USB, green lights on without battery, no light with battery.
In any case, pressing the power button cannot power on the device.
Please help. Thanks.
Sounds to me like your battery is having issues. Maybe try getting a new battery?
Thanks for your quick reply. I have actually got a new battery already. Still the same behaviour.
Then I can only assume it's the phone. Perhaps the charging circuit. In any case, sorry but I have nothing to recommend. :dunno:
If the plugging it into the wall without a battery in it didnt work... then try waiting for the phone to boot (assuming that it still is and the LCD is disconnected) and swipe where the unlock button normally is, pressing volume up or down, or perhaps try ghosting to adb and run adb devices in the command line... or simply try calling it lol. Also a good piece of information to get... does the backlight come on? If you can prove that the phone is in fact running, then it is most likely the lcd cable as someone said...

Thanks for your advice. I didn't drop the phone before it went to "no-response" status. I just put it on a HD dock for charging and the next day it doesn't boot anymore. I have put in HD dock for charging for a few weeks already.
My phone doesn't boot at all. I don't see any backlight or any special response. Or It does something that I don't know. I tried to plug into USB after pressed the button. If it's on, the computer should detect a device, right?
Any ideas are welcomed, i will try all.

I have the exact same problem, and would be grateful to know if you managed to resolve this problem.
So last night before I went to sleep, my NT had about 40% battery life left in it. I'm currently running the final alpha build of CM7. I've been experiencing really bad wifi loss issues and have kept the 'Never' option enabled under the wifi sleep policy (thinking that would help hold the connection).
I woke up to find the NT was turned off. Figured that was odd as I was only asleep for about 5hrs. I turned it on and then noticed it got into the OS and then died. I did see the battery icon was red briefly.
I then plugged it into the wall and it was boot looping. I saw the 'n' logo pop up, screen went black, 'n' logo, etc. etc.
After numerous attempts of holding down the power button for 20+ seconds, holding power+vol down for 10 seconds, plugging it with or without an sd card into the wall and computer, nothing is happening.
The computer does see something as I'm hearing the common connected/disconnected tone from the USB port. Now I'm noticing that plugged into the wall, the 'n' on the cable stays orange. It never turns green.
Did it go 'poof' in the night somehow?
[EDIT] Ok after leaving it plugged into the wall for about 15mins, it suddenly turned on but had a google framework FC error. Yeah, not sure what I should do at this point. It appears to be charging...
It's been noted by others that if the power level goes below 15% you mustn't turn the device off if you don't have the original charger nearby. If it dies you need to charge it with the original charger for a bit before it'll power back up.
I assume this means that you can't run it off the cable while you've got a completely dead battery. That kind of stinks but isn't too surprising, a lot of devices are like that.
So does that mean that if the device is <40% of battery I need to plug it in if I won't be around it for a while? Not sure I'm cool with that. Battery life was great all day yesterday but somehow it dropped 40% in under 5hrs while asleep.
I can't really say much as I haven't dealt with it personally. People were talking about it in a couple threads about the NT's charger and unique 12 pin cable.
Here's what I understand from what I've read:
You can run it until it's empty all you like. You'll just need to use the Nook's factory charger (or a compatible 2A charger with bridged D- and D+ pins) AND (this is the important one) the factory USB cable to charge it.
If you run it until it dies you have to charge it for a little while before it'll turn on again, BUT you have to use the original cord and charger. It won't charge off of a regular micro USB cable nor will it work if you're using a 2A or smaller charger that doesn't have the middle two pins bridges (the Apple UBS chargers won't work nor will your PC's USB ports, for example).
The NT will charge, albeit slowly, if connected with a third party cable or USB charger (without the data lines D- and D+ bridged), but not if the device's power has been depleted.
So I suspect something sucked up a lot of juice while you weren't using your NT. Not a huge deal, but definitely annoying. Plug it in for 15 minutes and you can get rolling again.... BUT only if you're using the original charger and cable. Lovely isn't it? It's not a huge problem but it is annoying. I wish you could at least use the device with a dead battery while plugged in.
I just mention the charger/stock cable thing because I'm sure someone will probably see this post in the future and may be having that particular problem resuscitating their NT.
Cool, yeah I don't specifically set out to run it down to zero but since the device is clean with minimal stuff running in the background, it's difficult to know when this might happen again. I assumed I'd wake up with like 20-25% battery left. The framework FC is also something I'm concerned about but maybe it was just a fluke.
Ah well, really do appreciate your input and I'll be sure to keep the stock cable/adapter on hand when I'm on the go.
Battery showed fully charged, I rebooted to do another CWM backup and then when it came back up it showed 84% charged. Lol. And this pic made me laugh even more. Time to get that lady from Poltergeist involved I think...
The Google Framework force close is typical of stock rooted NTs. I don't believe it ever did any harm to anything though. Just that it sometimes appears on reboot.
I'll ask one additional question as to not make another topic since it's related.
Opinions on battery calibration with the NT? That was one of the reasons I didn't charge it last night as I wanted to fully run it down and then fully charge it back up. Does the NT require this with a new rom install? That pic above shows the battery gauge clearly wasn't correct initially.
Your battery is draining overnight because wifi is running the whole time (as you stated in your first post).

That's what I obviously thought of at first but it didn't drain nearly as much when I was using it throughout the day. The only thing I can think of is maybe the fuel gauge itself was wrong from the start, which refers back to my calibration question.
My GS2 has the sleep policy set to 'Never' as well and only loses maybe 7-8% after being asleep for around 7-8hrs and it certainly uses more juice in sleep due to the cell communication, etc.
Has anyone ever see the notification LED on the Amaze go green when charging while shutdown? With power off, mine stays orange forever - even after unplugging, right up until I power it on.

Yes. I was actually conditioning my battery last night so I turned off the phone to let it fully charge.
Woke up this morning to a green "fully charged" indicator.
So I looked into this further and found the problem. In case it may help someone in the future....
It seems as if the 12 pin extmicro usb cable that comes with the Amaze is more reliable and faster in terms of charging than the standard 5 pin micro usb that I had been using. Among other things, micro usb connectors are not long enough for a reliable connection (depending on the case and how the phone was positioned, my battery could actually deplete overnight using the 5 pin). I don't think this in itself was the problem, but it wasn't helping.
I'd also seen reference to the installed version of Recovery having an affect on charging. I had CWM 5026. As soon as I installed 4EXT 1005RC4 the led behaviour was as nguyendqh had described.
That's because the CWM version you had probably or most likely didn't support power off charging.
Two really good finds bro thanks for linking to the threads by the way. Very helpful.
I didn't think to mention which cable I used because I didn't know it made a difference, but indeed I do use the extMicroUSB cable to charge my phone.
Glad to know there's a difference and glad to know I'm using the best option.
Cheers!
:crying: So this is the first time in a while I have posted here. But annoyingly enough my Gtab (for the second time) has not been taking charge. It will turn on when plugged it (but no red light) so I assume its the battery that won't take a charge. The last time this happened I formatted it, then nvflashed it, and let it sit for 24 hrs before charging. I will try that again but any help or input is appreciated
One of my Gtabs doesn't charge very well either. The charging pin is messed up and will only charge when I plug it in and prop it in a certain way. Sometimes the red light turns off, sometimes it stays on but still doesn't charge. Eventually I will have to re-solder the connection, but have been putting it off. If you cannot fix it by other means (try a different charging cable? reflash as you suggested?) here is a good set of instructions on how to do this.

Good luck and I hope it doesn't come to this. You could also buy a charging dock if you don't want to tear apart and solder your tablet. Also, here is some info on battery replacement if that turns out to be your problem.

+1 to DaggerDave's suggestion.
From my research the Gtabs power plug is very VERY flimsy. I've had to solder mine back on (and a hefty amounts of glue) and now it works fine, though I treat it very delicately. The dock is going at around $50 on fleabay (search malata/gtab dock)
YAY

tthats really good information thanks! :laugh:
but i did get it to work. I opened up my tablet and checked to make sure the battery was plugged in its socket thing. Guess what. it wasnt.
It probably became loose when i had to open it up to fix my screen. So all i did was reattach it and put a small piece of electrical tape over it, just in case.
