Hey Y'all,
I helped a friend of mine root his NT awhile back, and it was working fine for months. I showed him CM7 running off of the SD card and he liked it, so I set it up for him on Friday. I did a factory restore on the NT, and he reentered his BN account info. I then booted off the SD card and everything was working fine as I could tell.
He brought it to me this morning and it won't charge. The "n" is always green when plugged up to the wall and it never goes orange to indicate it is charging. But when I attempt to power it on, it is always displaying the low power message and says to plug in the charger.
What I have tried:
-I removed the SD card, and it still won't charge... (not that it would matter).
-I have 3 chargers and my own NT. When I plug a charger up to my NT it works fine and the "n" goes to orange. But when I plug the same charger into my friends NT, the "n" is green and I can't get past the low batter warning.
-I have had my friends NT connected to a wall charger for about 3 hours this morning and I still can't get it to boot.
Any ideas on what might be wrong and how to fix it?
Thanks for your time.
I found this thread and tried both of the suggestions and my friends NT still won't charge or boot.

The same thing happened to my wife's nook this evening. I think the battery is completely run down, but won't receive a charge for some reason. Her charger showed green also.
I tried, removing and reinserting the SD card and also holding power for 20 seconds. I finally was able to hold down the power and the N button down for about 20 seconds. This did the trick. It showed that the battery was too low to turn on. After about 10 minutes, it booted.
Hmm, I get the battery is too low to power on every time I hold down the power button and the "n" is always green on the charger.
strandedinar, did you have the power cord hooked up when you held the power button and "n" button down for 20 seconds?
So connecting the STOCK charger and the STOCK cable and leaving it alone for an hour or so isn't doing the trick? That's really the most that many of us have had to do... No "n" button needed either.

Yes. The nook was plugged in and the "n" was green. The Nook wouldn't power on - My wife was convinced it was my fault for rooting it...
I left it plugged in like that for 20 minutes, but nothing happened when I tried to start it. The charging light was green. I finally tried the power + N button trick and then I received the notice that the power was too low to turn on. This was the first time I received this message. After this, the color of the charging light changed from green to red/orange and I could tell that it was receiving the charge. After 10-15, it power on and has worked normally since.
I tried every thing I could think of and google and nothing worked. I took it to BandN yesterday. They thought it was a typical issue that they see a lot of, but after 3 folks at the store couldn't figure it out, they called 1800 support. Support said it was a bad usb port and swapped it out for a refurbished model.
I still think I could have fixed it, but after a couple of days my friend was getting antsy for it.
Thanks for all of the responses.

How did you do that? I was trying to hold the buttons and never got anything.
My NT has no juice to boot, but when I plug in a power cord (stock), plugged into stock power charger, it tries to boot up. Power indicator does turn orange, but then it runs out of power once it starts booting and turns off. After a few second it turns back on, and repeats same cycle again. It never boots to the point where it can actually sleep, seems that boot-up process takes more energy than charges could give it.
Try charging it from your computer. Just as suggestion not sure if it will help.

Hello Galets, did you manage to finally charge your Nook? I have the same problem as you have - when stock cable and charger are plugged in - device tries to boot and screen shows up but due to lack of power in accum it turns off and in a few seconds the cycle repeats.
I hardly understand - how it is possible that having mains power plugged it - there is not enough energy to charge and do other necessary things...
---------------
UPDATE: problem solved. In order to solve it, I had to disassemble the tablet and unplug the screen cord, then I put the power cable in, battery charged up for about an hour or so, then I plugged screen cord back in and turned it on without a problem. The down side of early charge attempts is that tablet decided that I had 10 failed boots and it reset my previously rooted device. Now I have fresh and clean stock 1.4.2 version.

how did you unplug the screen cord? I've looked up how to take apart the nook, but I'm not sure which one would the the screen cord. Did you follow a tutorial somewhere, or was it easy to figure out once you opened it up?

ACL3, check this link: http://www.ifixit.com/Guide/Installing+Nook+Tablet+Display/11148/1.
I did not really follow the guide. I was looking for first two bolts to unscrew. The rest was quite simple but challenging - i don't usually disassemble things.
I did not pull out any of the buttons or battery from where they are and simply unplugged their connectors too - you will see 3 small foam rubber black box-like pieces (in step 9 they only marked one of them). There are plastic connectors under foam rubber pieces.
Be careful not to short-circuit anything with metallic tools.
On the attached image I marked the screen connector. I unplugged it by gently hooking it with two small screwdrivers. When putting it back I gently pressed it until I heard a click. And make sure those small slots on connector match with corresponding ones on motherboard.
Also, when finishing assembly I ran into a small problem with corner flap (which covers sdcard) - it did not want to smoothly slide in and out. So, pull it off completely and after putting plastic cover in place and screwing last two bolts, put it back - some small help of small screwdriver will be needed.
Hope my explanation was helpful

thanks, looks cool. I've never taken anything apart before and I'm afraid of short circuiting something. I think I might try this.
Here is the deal.
The usb port on my EVO 3d fried a few months ago when my kid spilled water on my phone. Everything else worked fine, so I bought some extra batteries and an external charger and would just swap them out. Never had an issue with it until yesterday. The phone was working but the battery was low. I shut it down and waited for all the lights to turn off, took the battery out, put a new one in, and hit the power button. Nothing happened... no red light, home buttons didn't light up, nothing at all. I tried to swap in two other fully charged batteries (stock and non stock) with the same results.
I've tried taking the battery out and holding the power button down, tried holding the camera button + power button, volume up/down and power button, and other various combinations in hope that it works. The problem is that I cannot connect a cable to the phone because the USB is, quite literally, melted - has been for two months.
Is there any hope? Or is this a lost cause. I am reasonably skilled with a soldering iron and considered replacing the USB jack but I don't want to go through the effort if there is an easier way, or if this is a hopeless cause...
BTW this is an unrooted phone...

If volume down and power button isn't turning it on, I'd say it's toast. You're probably lucky it lasted 2 months after the spill. I wouldn't bother soldering a different usb port likely wouldn't even work even if you could get it done. The contacts/solder points are in very tight spots and a portion of the board itself could be bad since it was wet, which is causing the problem.
If you could get a hold of a really cheap 2nd device say with a broken screen, these phones are very easy to tear down to the main component and swap out.

Bummer, I figured that would be the case... I've replaced screens from other phones before. I guess I'll try that.

You'd just need to switch out that board of components in the 3rd to last pic. I would suggest checking sites like craigslist first to see if there is one for sale in your area for cheap that you could just activate. I picked up one 2 weeks ago for $80 after I shattered the screen on mine. You should be able to find a broken screen one for darn cheap on ebay just make sure it has a clean ESN or it's going to be worthless.
Gentleman, my optimus g is showing some really strange behavior. If the battery is fully charged, or above 60%, it works flawless, after it drops below that, there is a chance that the power button will start locking in the pressed down position. After this happens, it is a no come back, the phone keeps bootlooping until the battery goes dry. At first I thought this was a problem with the battery, I got It replaced and the problem persists. I am starting to think this is a problem with the power button flex cable, and I was wandering if anyone knows how to replace it. I've replaced cell phone's screens and such, I have taken the motherboard out and found the flex cable, but I am not sure how to remove it, as it seems that it is firmly glued to the chassis. If anyone could give me some suggestions I would appreciate it, thanks
I took apart my GS4 today and discovered that the problem causing my phone to turn off on the boot screen is the power button. This was a complete random and freak occurrence. I have had a case on my phone since the day I bought it and I can't see why the button would be damaged. I removed the physical button (the one you depress with your thumb / finger) and still the phone would turn off incorrectly. The issue has to be with the power button, but it's soldered on and I have no idea what to do or how to go about repairing it.

Hi all, was hoping someone could help.
I have recently, last month, changed the battery, so I know it's not the battery. When I plug in a charger the phone is unresponsive, drawing only 0.05amps. if I leave it over night the green led will light up and when I press the power key the screen says 100%. When I try to boot there is no response. I have tried
Power +vol down
Power +vol up
Power +vol up +down
Power and all buttons
For about 30sec but still no boot or anything. I'm thinking maybe fried board, but was hoping software issue. Is there anything i could try to boot it?
Many thanks
Possible that a connector came loose?
Make sure no foreign conductive debris was accidentally introduced... a small loose screw. Check that all screws are in place in the assemblies.
Is the power switch good?
Hi thanks for the reply, I checked there's no loose or foreign object near the charge port. When I assembled the phone all screws were replaced so no loose screws. When the phone is charged ,ie green led I press the power button and the phone activates the screen to display 100%, this tells me the power button is working. Do you have anymore suggestions would be helpful. Many thanks.

If it won't go into the boot menu it's not looking good. Try a hard reset.
The subassemblies when out of circuit are susceptible to ESD damage. Handle these like a stick of ram particularly the mobo and display. At the very least raise room humidity to 50% and wear all clothes. In addition a earth grounded ESD mat and wrist strap are recommended as are following ESD protocols.
Otherwise you may or may not get away with it.
Hi thanks for the help. Yh the problem occurred during normal use. How would I do a hard reset if no menus are displaying? Many thanks.

Pull battery connection.
Recheck all ribbon connectors while you're at it.
Yep done that still the same. No response. Guess the main board maybe fried.
