I just got my new Prime in today and it is completely dead. Plugging it in via the wall charger or USB in my computer, I do not get any charge lights. From what I have read, the wall charger can have some issues and it may take several hours for the unit to charge enough to turn on, but I do not get any charge lights. When plugged into my PC through USB, I dont get any new devices in device manager.
Are there any tricks or resets that I have missed? I will leave it on the charger, but it looks like I am going to have to return it for another one
This happened to me yesterday. I had left it on while out of town, got home and it was dead. I plugged it in and no lights, no sound, no nothing. Left it plugged in for about 10 minutes and then went back to try. Held down power button for about 20 seconds, nothing. Tried holding it down again for about 20 seconds, nothing, and then when I released the power button it vibrated and powered up. Don't know if this helps, hope it does.
Try the paperclip into the reset hole below the micro-sd card slot.
Try putting the power adapter in a baggie and throw it in the freeze for a little while. This is been posted before and got me going again after mine did the same thing. I had always left my adapter plugged into the wall and some seem to think it for whatever reason causes it to overheat or stop working.
Last thing. The Prime will not charge off of a PC using USB ever. Only 5vdc from USB and it takes like 12-15 volts to charge the Prime.
Good luck,

That is incorrect. It will charge, when turned COMPLETELY OFF from 5v, although it is at a VERY slow rate. 15 volts is required for full speed charging.

I stand corrected then. I did not know that. Thanks for the heads up!

The freezer trick is for if the charger seems to be overheating.... If you notice it gets very hot then thats a quick way to cool it down (happens from time to time)
You can also try ipad chargers, they should be able to put out the 12-15 volts the prime uses to charge, or you can build a custom charger, theres a few threads on XDA about it
It will take roughly three times longer to charge via the computer with the prime OFF, with the prime on its using about as much power as its getting so having it plugged in to the computer will do basically nothing.
Hopefully this helps
Ipads have a 3,6 v battery and they chargeat 5v usb

Look at your charger brick. The plug end can slide off of the brick part. I've had mine slide slightly and you couldn't tell that there was not good contact between the transformer part and the plug part and it would not charge. I thought, oh good, my charger is dead then I realized what was going on. Snapped it back it place charged fine.
yep, gotta put some force towards sliding it in until it clicks

just thought i throw in there
it doesn't have to be completely off
as long as the screen is turned off, it'll be charging your prime too~
but as the poster says, it is a very slow rate
prob takes about 8 hours for full charge~

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.

Then just let it run down passed 90% (like 88-89%) and see if it charges. If not, then yeah, sorry.

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.
Information of PSU model with a known fault here:
http://forum.xda-developers.com/showthread.php?t=1081435
So I just woke up about 2 hours ago. Grabbed my phone off the charger.. checked news email etc. Then put the phone down and got ready for work. Went to get the phone about an hour later (1hr 10min) and my battery is at 8%.
Nothing is on.. I checked task killer and there was nothing crazy. Phone is not warm in any way.. I'm connected to WiFi.
It's totally throwing me. It's almost as if it wasn't charging last night.. but I would have noticed that when I took it off the charger as I have the battery widget on my home screen.

wall charger, same one I use every night. I charged it back up, and now its acting normally, i think , somehow, it just didnt charge overnight.
hahaha, found the problem
I use a USB extension so that I can use my phone while in bed (the outlet is too far for the standard cable) and I guess it had pulled out slightly and not charging.
but it was still plugged in enough that it made a connection when i checked it a little later, indicating that it was charging.
At least it wasnt a real problem
So with my TF101, the tablet powered up right when I plugged in the charging cable so I'm assuming it does the same with the Prime. Should I power it down immediately and charge it for 8 hours or should I go through the initial set-up and then power it down and charge it?
I personally powered it up, ran the setup, then let the battery run out, then did a full charge. Mine is fine after doing it that way, and from what I have heard these batteries don't really need any conditioning or anything like that so it shouldn't matter too much.
How much juice did your Prime initially have out of the box?
mine only had 4% out of box so I had to charge from the getgo.

i had 28% out of the box, went trhough the setup then plugged her in.
Power on
Just got my Prime delivered from Office Depot(yea!) I'm a bit nervous because I plugged it up and the screen briefly lit up and I thought I saw red battery icon. The unit wont power on so I'm hoping it just needs to be charged up. Anyone else had this happen?
Thanks,
Wann
You can check the power button while charging, to see if it's really charging or not. Lots of problems with OEM charger made me look more often at that little LED.
power
I must have been impatient. I was able to start it up after 30 minutes
Yesterday I let my phone die (low battery > powering down) and it stayed dead for 30 or so minutes. I plugged it into my wall charger and nothing happened. It didn't boot up, and there was no LED light.
I plugged it into USB and got a WHITE light, but it didn't charge. Even if I remove the battery I still get the white light when it's on USB.
I tried leaving my phone on the wall charger overnight, nothing happened.
I left it on USB for 4 hours, still nothing happened.
To sum it up:
Plug it into wall charger: Nothing happens, no LED
Plug it into wall charger with battery in: White LED
Plug it into wall charger with battery out: White LED
Nothing will charge it. I tried 2 USB cables and 3 wall chargers. I know they all work because I also used them to charge my replacement phone.
Returning to Sprint is NOT an option (I live in Canada)
What can I do to fix this?? The phone is less than 2 months old

Your battery has been drained out completely.so you will need to boost up your battery.either connect your battery to a compatible battery charger or do following step
take one of your usb cable and cut it. you will get four wires. you will need red wire and black wire. Take out the photon's battery and connect the red wire to (+)positive terminal and black wire to (-)negative terminal of the battery as indicated on the battery.now connect it to your wall charger and let it charge for 15-20 min and after charging insert the battery in your photon and charge like normal.
Huge thanks! Worked great, my Photon is back up and running! I stripped the cable I had from an old audio player and connected it like you said (the (+) and (-) are the outermost terminals).
I'm going to invest in a standalone wall charger for the battery now, as well as tell Tasker to turn off my phone at a reasonable 10% battery so it doesn't completely die.
Thanks again for the help!

Proud that it helped..
But remember not to overcharge your battery with this method this is only for boosting the battery. don't charge for more than 15-20 min.
having a very similar problem as op but...
Hey wuddup fellas,
I'm a long time lurker, first time poster. Well, never really had to until now. Anyways, Im having a VERY similar problem as the OP but with the difference that my white LED only comes on for a short amount of time when connected via usb, maybe a couple mins max. Not to mention, for some reason, the white LED only comes on when connected to a specific usb port... I got 3 on my laptop (1 on left, 2 on right) and it only comes on when attached to the 1 on the left.
Lead up to failure: I was on texting when the 5% low battery pop up showed itself. I usually get 10mins before it dies so I didnt sweat it. Then, a few mins later it died. Ok, np, I'll just connect the charger wait a sec and we'll be good to go... Guess again, when I plugged in the charger, the charging indicator didnt come on, which I thought weird. Maybe its super dead, I'll just wait a few mins and it should be able to turn on... Nope, nada. So, I pop in the extra battery I got... Same thing happens to that one! Now I'm at a loss.
I read a few forum posts around the interwebs that sound along the same lines of whats going on with my phone. This post turns out to be the closest, so I try and jump start my batteries... Again, nada. Another post says I need to charge the battery out of the phone. So, I Amazon a standalone charger for the batteries. Throw one on the new charger, battery is completely dead, takes a few hours for it to charge. Throw the newly charged battery in the phone... nothing. Charge and throw the 2nd one in... Again, NOTHING!
Now the white led wont come on anymore. Which I guess it wouldnt need to cause the batteries are fully charged. But now I got no clue where to go... please if someone has any insight, i'd greatly appreciate it.
I can only charge from the car charger a very old laptop and by computer if a hdmi monitor is pluged in to the photon.
The laptop has a dead cmos battery so it sites at the hit F1.

Sorry to wake up this thread, but I'm having a similar problem and tried the wire method. When I plug into the computer I get the same white light, but I also get the white light when I plug into the wall. After trying with the wire, I plugged into the computer and pressed the power button. The light turned green, but the screen still didn't come on.
do you have spare battery from any other mobile.just take it and connect two wire + and - to the spare battery then other end to the photon phone pins using crocodile clips with same + and - symbol just double check before connecting don't connect reverse only connect to two pins then try to turn on and post your reply..
Motorola Photon Q, Dead. Fixed easy
I did as some suggested above, but without removing the battery. After removing the back, I just unscrewed the (+) and (-) screws on the battery, lifted up the battery tab, then clipped small alligator jumpers directly onto the battery tabs. I connected a power source of 4.35v until the battery read 3.77v, then removed the power. Then I started charging it with the standard wall charger and it powered up -- now working great.
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.
