I have recently purchased a Nexus 7 in order to do an in-car install.
When I am using the device and plug the charger in, everything is fine. However when I leave it for a while and the screen goes off, then I plug the charger in, nothing happens. I can then unlock the device, use it while it is plugged in and it is not charging.
I've tried doing it while it is plugged into my computer, it recognises it as a device and I can access it on my computer, yet it still doesn't charge. Again, when the screen is active and I plug the charger in, it works fine.
Any ideas as to why this is occurring?
Thanks

Is there a connection between the hardware and the software?
My hermes (as weird as this may sound) has this problem where. if I put my charger in, and slightly move it around, it will no longer charge and pulling the charger out and back in does NOTHING
If i connect my phone to my PC via USB.. it will work, but if i want to connect it back to the regular wall charger, it won't charge until I completely shut the phone off, then turn it back on.
However, with my phone turned off... whether it's on the USB connection to PC or wall charger, i can jiggle the wire and do all sorrts of stuff and the orange charge light will stay on...
anyone know what this means?
I don't know but I'm having the same problem.
Totally stock (but i don't think it matters).
Plug the phone in, orange LED comes on.
Hold it or place in on the counter five seconds later, LED is off.
Had the phone since 6/4.
Anyone else having issues?
Are you using the AC charger ? I have two Evos and one of the chargers does what you are describing. The orange LED comes on and then goes off after a while and the phone stops charging. Does it on both phones, the other charger works fine with both usb cables.
Are you using the USB charger with a computer or laptop or plugging straight into the wall with an AC charger?
This does make a difference because if you are charging with a USB + laptop combination you could be suffering from the computer going to sleep and disabling the USB ports power to conserve laptop battery life. If you are having the issue when plugging into the wall, try plugging into a computer and selecting the "Charge Only" option when your USB debug comes up. Once it does this, allow it to charge for a period of time and then turn the phone off, switch to AC power plug and see what happens.
Perhaps you had some kind of over voltage spike on the charger through the AC plug. I could see it possibly tripping something in the phone to stop taking charge to protect the handset.
Also make sure if you do use a laptop, use a USB 2.0 or better port. More power and faster connection. Gotta love it.
Your charger may not be sourcing enough current anymore (for whatever reason). I have seen the exact same behavior with USB car chargers that were only sourcing 100-150mA.
Have you tried plugging the USB cable into a modern desktop PC? (Some laptops have reduced current ports, so a desktop is a safer bet)
Its definitely a current issue. I tried to charge my phone using my bluetooth headset's wall charger, but I got the behavior you are describing. The bluetooth headset's charger just doesnt put out enough current.
Are you using the charger that came with the phone? if so, you may want to exchange the charger...
im having the same problem when i connect it to my desktop, it sees it for about 2 secs n then disappears. My computer at work has no problem seeing the phone. i wonder if i need a driver or something for my usb ports, anyone have any ideas??

Probably not a driver issue, but that that rail from the power supply is either undervolted (say 4.6V instead of 5V), or can't provide enough current (amperage) or both. If I recall correctly, the Evo needs 5V @ 1A (+/- 3% tolerance).
Phone not charging
my phone has been charging fine since I got it... even been using the night desk clock app while sleeping at night for the alarm with it plugged in... everything was good...
With my phone about to die today, I plug it in to the wall charger, the led/batter indicator shows that it is charging... then POW.. it says I have a low battery and it needs to be plugged in... WTH??? it is plugged in!
The only thing I did today was flash the new boot.img for the cap fix over in Toast's thread...
Weird thing now is that I took my hero battery and put it in my EVO, plugged it into wall charger, and it stays charging... So, I put my EVO battery in my hero, plugged it in, and whola... it's now charging...
Please help as I am baffled.

that's your problem right there. that custom kernel is known to have charging issues.
I'm having the same issue with my car charger consistently. Plus my AC charger less consistently. For example, I'll go to bed and plug it in, the next morning I wake up and see the phone is at 80% charge and isn't charging. At some point over night, it gave up. This is with the stock charger too.
Anyone else notice that it won't charge from a computer? (well monitor) With my Aria i ran a USB cable from my monitor at work to the phone. the monitor wasn't connected (USB) to the computer, and it would just work as a charger. Doesn't seem to work with the atrix. anyone else able to confirm?
more info. does in fact charge when connected to a computer. but due to security reasons the company does not want phones connected to the companies. That is why i was using the monitor. Going to have to look into why it doesn't work this way for this phone. or just buy a longer cable and use the wall plug.
Mines actually not charging when connected to my laptop, wall is fine. The phone recognizes that it has a usb connected, but it doesn't charge and battery state still reads as discharging.
Also wondering if this is an issue for anyone else
Mine charged extremely slow from my PC and my laptop, the wall charger does it much faster.
USB ports on a computer don't usually provide enough voltage to charge a phone as fast as they normally do when plugged into the wall. My motherboard actually has a piece of software that supposedly enables phones to charge faster when connected to a USB port, but i have yet to try such a feature.
I've had my Atrix plugged into my computer for roughly 3 hours now, and so far it's gone from 30% to 60%.
I wouldn't be the least bit concerned if it was charging slowly, it was actually lower after unplugging than it was when I plugged in, and no charge symbols appeared. But if I plugged it in the computer saw it and soon as I unplugged the message popped up saying low battery please reconnect charger, and when reconnected it went away.
But there was no charge symbol and under battery status it said discharging.
Now I just unplugged from wall charger (worked fine first time) and plugged back into laptop, its charging fine so hopefully it was a one time thing.
Ah, so thata what it is; I have had mine on here for a while now and im still at 60.
Rooted/ROM Captivate
Rooted Atrix
When i first plugged mine into my desktop computer, it wouldn't charge at all. I then installed that motosoftware that came with the phone and after it finished the phone started to charge, but very very slowly.
Every computer ive tried works fine.
But when i plug it into a wall charger(not one that came with atrix) it starts freaking out lol. "unplug to save energy!!" flash on & off 3/second...atrix charger works fine tho...lame
You need the driver off the motorola site to charge the phone from your computer.
Yea, computers work, monitors don't. I'm guessing that the USB hubs in monitors don't have enough juice, even though they did for my Aria.
ive had it for a month and a half and now its doing this, plug in the charger to the tablet and nothing. ive tried with different outlets aswell ive checked my power adapter to see if its one of the effected ones but mine was a pre assembled one. ive also restarted the tablet with no luck. time to call asus?
Do you have another device that charges by usb, that you could plug in to see if it sees anything for power? Not sure on the usb pinout for our chargers, but if someone knows, you could use a voltmeter to probe it and see if it has any output.
k got it charging now, hooked it up to my pc with the usb cord to see if the cord or the socket is shot, still connected to my pc....but it reinstalled device drivers as if i never used it on my pc. i turned usb debugging on then off, then i unplugged it and put the cable back into the power adapter and its charging
this is concerning, seems like a usb driver issue that effects the port not sure if i should call asus and do something about it
Sorry to bring this up but I started noticing this today too. I've had mine for about a month and everything's been fine. I noticed that the battery was in the 30s so I plugged it in via the a/c adapter and neither my battery widget nor the system battery icon change to the "charging state". I shut the device off to see if it would charge quicker and left it off for what must have been an hour and the battery has only increased by about 7%. I'm timing it now to see how long it takes.
This happened to me this morning. I couldn't get the tablet or the dock to charge. The dock was at 3% and the tablet at around 75%. Neither would charge either singly or together. I tried using a normal 5v USB charger for a few minutes, but without success. Then I fiddled with the charger and uncoupled the 3 pin UK adaptor. It then started charging. I'm not sure if it was coincidence or not, but at the moment it's working.
B50K tablet and B50K dock.
I have a B50 also running the newest firmware via Revolver 1.1.1, I just booted up my TF after an hour of it being off and connected to the A/C outlet to see how much it had charged. It increased 2% in the past 70 minutes. Something's Fishy here.
did u guys try method of hookin to your pc, then turn on usb debugging.
i havnt had any issues recharging since this thread was made
I connected it to the computer a few times and USB Debugging was already on, I just turned it off and I'll try and connect it again but I'm currently backing up stuff with CWM.
Edit: I just cycled USB Debugging a few times while it was connected to my PC. XP (virtualized through Arch Linux) recognized it each time, but still no change in the charging status. I'm going to unroot and go back to the stock 3.1 to see if it's a software or hardware problem.
Edit: seems to be a hardware problem considering I reflashed it back to stock (unrooted) and it's still doing it. Awesome.
Same problem here. All of a sudden I didn't see any status from the dock battery (dual battery widget). Tablet charges just fine, but the dock won't charge. even left it connected to charger overnight but the dock led just keeps blinking orange (/red). I'm afraid the dock will have to go RMA.
Just got an email back from Asus and they told me to fill out an RMA. It'd be nice if I got one out of the B70 batch as a return
edit: sadly, that didn't fix it. I re-rooted, let the battery drain down until it turned off and wouldn't turn back on, then let it charge for 2 hours. I turned it back on and the battery was at 5%
When on battery power, it boots just fine. But if I plug it in, it shows the moto boot screen, and stays on it forever - and while it's on that screen, the battery isn't charging. I have to unplug it, take the battery out, then boot up without plugging it in. That itself isn't a problem...just a pain.
The problem is when my battery is too low to boot without plugging it in. I can't boot it up on battery power, and I can't charge the battery by plugging it in.
I finally got it to work by borrowing a friend's wall-mounted external battery charger and got the phone up and running. But what the hell do I do for next time?
Also, I installed CWM and it doesn't work, ironically, because CWM requires power to boot into recovery, and my phone won't boot at all when plugged in. The normal recovery has never worked on the phone, since its unboxing, and I'm starting to get pissed about this lack of recovery. Any ideas would be much appreciated.
Are you using a USB port to charge?

I've tried USB and a wall charger. When plugged into USB, it turns on but will not enter CWM still. When connected to a wall charger, it stays at the Moto screen forever, charging.
When the phone is switched off and plugged to the wall charger you need to do a long press on the power switch till you will see the Motorola logo again. Once the phone is fully booted it will start charging again (still plugged to the wall charger of course).
