I have a brand new Nexus One bought on last year April. For some reason it wasn't to be used. Yesterday, I got it out of the package and charged it for ready to be powered on. Unfortunately, it reacted nothing as I pressed the power button! I took out the battery and put it into other Nexus One, it showed the battery was 100% charged.
I took back the battery and repacked it to this new Nexus One. I tried to press the power button more and more with data cable connected pc. Nothing happened. Just one time, the sceen lighted on and the "X" in four colors appeared! I didn't know why it was powered on. Maybe I pressed the trackball or volume up/down buttons, God know it.
The X sceen lasted almost for ten minutes and then sceen was off! Yes. It shutdown! I can't power it on anymore!
It seemed the hardware was OK. It may be the locked by the outdate android system. The android prestored in this phone is version 2.1.
Any advice is welcome. Thanks.
Can u you go in fastboot? Press power button+trackball..if so then you can recover your phone by unlocking bootloader and falshing custom recovery.
Sadly, It can't be power on and go in fastboot by pressing trackball+power button.
Any more advice?
Check the battery terminals just to make sure they're not dirty.. Sadly, you MUST be able to at least be able to boot something (hboot/fastboot) in order to troubleshoot anything software related. Sounds like you've got a hardware issue that could be one of (literally) a million things.
Sell it on EBay for parts. You can probably get $50-$60
you could try pressing pwr/vol-/trackball all at same time, hold down for around 30 seconds to make sure

try power on without sdcard by manual methods and plugging in and plugging in with no battery
I have seen a video on YouTube on how to fix the power button which is known for messing up and how to turn it on. Search YouTube
Sent from my Nexus One using XDA App
is it that the power button is not working? that would be weird for a new phone though.
have you tried to turn it on using the "jump start" method?
connect the cable. led the charging led come on. remove the battery, wait for the led to go off (while cable is still connected) then pop the battery back in.
see if you can get it to start that way
When you plug charger cable in your Nexus, does the orange or green LED go on?
If one of them does and stays (green for full battery, orange otherwise) - then your problem is most likely the power button. It may not be the only problem, but at least the one that's stopping you from turning on your phone. You can try "jumpstarting" it by inserting battery while charger is connected.
If you don't see LEDs when plugged in - your phone is done.
If you see blinking LEDs - battery terminals might need cleaning/fixing, it usually happens when the battery is out of the phone.
I have a new Motorola Atrix HD. I was using it and the screen went black. i hit the power button to unlock but nothing happened. i plugged it in but nothing happened. i took the back off to see if the battery was disconnected. I didn't know the battery was different than other phones and ripped the power cord connecting the battery to the phone when i took it out. lesson learned. Ordered a new battery and installed correctly. phone won't turn on. The green charge light blinks when i plug it into the wall and then stays on for about 20 seconds and then the phone tries to turn on but while the motorola icon is illuminated, it cuts back out and repeats the cycle. I left it plugged in for a couple hours and still the same thing. i tried holding in power and volume buttons for the boot screen. if i do that just as the phone attempts to turn on i can get the screen up and scroll the list of boot options with the power buttons but i can't select any of them and the phone cuts out after the same amount of time. Everytime. When i plug it into my laptop, the light blinks on and then stays on like with the wall, but the phone doesn't attempt to power up. Please, any help would be greatly appreciated. i have read a lot of forums where the battery was acting up because of the chargers people were using. The difference between my situation and those of the people i read about is that my boot screen cuts out and cannot be used. This all happened 2 days after my exchange period ended and because i took the back off myself, best buy won't have anything to do with me so i'm on my own and cannot afford another phone right now. Thanks in advance for your time and concern.

Is it possible that the that connection between the power cord and the phone itself is loose or damaged? I'm just guessing here as I have never opened up the back of my phone.
I would check your battery terminals then leave it to charge if it does. You could also try a factory cable. Another thing would be to try fastboot while connected to your laptop and see if it stays on, and if it does, try reflashing all partitions.

So I took my charger with me to class today because my phone was almost dead. As it was charging I began to fiddle with it ex: go on reddit . Suddenly The phone began to lag and the screen shut off. I unplugged it and began to hold down the power button.... Had it held down for about a minute and still no results. The charging light is stuck green even when off the charger and the navigation buttons are stuck on. When holding down the power button the navigation buttons would also flash as it normally does but im not getting any feedback from the device. Anyone have any solutions? I need my phone to be working asap. If there isnt any hope i may as well upgrade.
Little update: I let the battery die out and plugged it into the charger. After half hour it still wouldn't turn on. Several hours after that I found it on and running. Very strange....
I recently went on a 3 month trip. Before I left, my nook was working perfectly fine, when i got back, it didn't work at all. It's not dead because i left it plugged in overnight but it still didn't turn on. when i plug it in the LED goes from orange to green and then off (or green to orange, i can't remember). The screen doesn't turn on at all. I can't get to recovery either.
This is a Nook HD, I believe it had CM11.
:crying:
Can this be fixed
or should i plan it's funeral
Same here
The same has happened to me. Screen doesn't turn on, but there is power, I can play it into my laptop and something is there, just not enough.
Good excuse for a new tablet!
It can be fixed. I've done it before. It has to do with the fstrim not being compatible with certain hardware versions of our device. If I can remember how I fixed it, I'll post it here. Trying to fix mine (again).

If would be fab if you could fix. Seems to be a common issue
I was able to fix it. YMMV.
1) Make sure the Nook is completely off and unplugged
2) Take out your sdcard
3) Hold down power button until the "battery depleted" icon shows, then promptly plug in the power before the icon disappears.
4) Let it set. The screen will go black, then it will attempt to boot and get stuck on the faint black screen, but this time, the charging light should stay amber.
If you want to be safe, wait until the device reboots itself. That could take hours though. If you're plugged into the wall wait at least 30 - 45 minutes before holding the power button down til it shuts down and then rebooting it (with the sdcard inserted).
Good luck, I hope it works for you.
EDIT: Also, I've read this may also have to do with wifi sending the device into some sort of strange bootloop when the screen is off. I personally believe it has more to do with the fstrim of JB but perhaps changing the wifi sleep policy may prevent this issue from happening again. I'm skeptical, but figured I'd pass that info along if anyone wants to try it as well.

Not sure we have the same problem. My screen doesn't come on at all, I don't get a battery depleted icon, no matter how long I hold in the power button. The only sign of life I get is when it's plugged in, when it goes from orange to green after about 10 seconds.
Thanks for the help, but I think it's a lost cause.
YMMV. But mine was the same issue. You should be able to get the icon by holding the power button down for 5 or 6 seconds. I'd say just eff with it until that icon appears. Try different button combinations. I used power and home trying to get the icon to show.

Anyway... since people are continually running into this kind of issue...
Give or take 21 seconds after turning orange it turns green during actual boot cycle into rom
Give or take 10 seconds after turning orange is cwm internal recovery.
After about 10 seconds the charging screen image disappears.
The charging screen image once finally no longer may not show up again until full power off/on (holding power button > 10 seconds or full battery discharge). Unplugging and plugging back in does nothing except making the device look bricked if there's too much light shining on it.
Device may not automatically leave the above state under a specific situation(s). May still need manual full power off/on.
Guessing 10 seconds could also be something else during the early/late boot process or other. The light changing color though should indicate that something is indeed happening.
Light should stay green during the boot process if its completely and fully no questions asked 100%. If you go based on that than yours doesn't appear to be completely fully charged which should either mean its turning on and using battery or not charging correctly.
The light turning off is curious. The device could be shutting off. If light comes back on a moment later then the device has rebooted. if the light stays off = n/a.
If its booting into recovery then the device would be available via adb. At that point it could be further evaluated.
On the off chance the screen was damaged it should boot and usb should be available via computer as well as adb.
If not then its probably toast unless its simply not getting a good enough current causing mislead battery stats and/or not enough energy to get to charging screen (bad wall power adapter in use, damaged power cable - though could be bad battery, defect, damage or whatever). OR there's some major error on behalf of the user happening (think should have tried that in the morning not while 1/2 asleep or came home from long trip and forget how that works).
Maybe the only other things are the emmc brick bug, was left sitting in the sun or heat or ocean air or other physical damage/defect even to the power port as well.
Or maybe it was mad that you left it. Shouldn't have hurt its feelings you know. At least its not crying battery acid on you.
That should just about cover everything except for the things not mentioned. Since its your device, you decide what happened.
Its complicated so anyone see any improvements, clarifications, or mistakes? Please put it in a post.

Bumping this thread to make it aware that there is a real answer. I have been able to duplicate this problem and rather easily too.
The problem is indeed from bad power. The device isn't receiving the correct amount of power needed to charge and start from a fully discharged battery.
To safely* duplicate this you can use a usb extension that isn't fully connected to the nook power cable. You may need to fully connect it first then slowly disconnect/connect till the light turns green when it should actually be charging. It won't actually charge in this state, or if it is, its very little and the battery percentage will continue to drop.
Leave the cable as is and unplugged. After the tablet is fully discharged, connect the usb cable. The light will change through the modes and turn off. The device will not turn on.
There are probably other ways to cause the problem like for instance a portable usb battery that doesn't put out enough juice (not the orange kind). Etc.
* It didn't hurt mine, but not my fault if it breaks your device.

I actually ended up fixing it yesterday!! I haven't touched it in about 3 months, and I was planning on just throwing it out getting rid of it some how. For the heck of it, I decided to plug it in, assuming that it was gonna go through the same process. But this time it went from green to amber, but it never went off. So I pressed the power button and the battery icon appeared. This was a really good sign. So I left plugged in for about 5 to 10 minutes then tried to power on.:fingers-crossed: As soon as I saw that '' Nook" boot up screen, my heart stopped. It booted up perfectly and I almost blew up from excitement :victory:. So I then flashed the stock firmware back onto it, so this would never happen again.
I guess the battery had to be completely depleted or just had to cool down. Idk but either way this was one heck of a miracle
So I recommend for anyone having this problem to just leave it off and don't mess with it. I wouldn't say for 3 months like I did but maybe test it each week or wait a month if you have good patience
Wow. Man, that's awesome! Glad you posted that update on it. Thought if you had posted an update it would be the opposite as in trashed it
Actually, I guess only you could answer if you had also moved/unplugged the power cable from the wall adapter or put it into a different wall adapter, etc. Thinking there could have been a difference there.
These modern day devices are so finicky, guess anything is possible. Like you say, maybe sitting without power is another answer.
From some experimentation I have etermined that your power adapter (that plugs into the outlet) is the issue. It does not like to be leaft plugged in indefinately. It will continually use power even when the nook is not plugged in.
Also, if you use a differnt adapter you will have the same problem unless it is also of the exact same voltage and amps.
Has anyone else had problems with this particular combination not turning back on? I flashed it several weeks ago, and every time the battery has died (its primary user is a toddler), it's been a hassle to get it to start back up: lots of fiddling with the power cord, power button, N button, leaving it alone, and trying again before it finally turns on. And that's after it'd be plugged in for the whole night.
Last night, I couldn't get it to turn on (even though I was messing with it for half the run time of Guardians of the Galaxy), so I left it plugged in. Usually, it acknowledges a button press by showing the dead battery or charging icon before blacking out again, but now the only thing that happens is the light turns green when I plug it in. No icons, no reaction to button presses.
Anyone know anything?
Did you tried turning it off by holding down the power button for >30sec?

Sorry this response is so late: I never got an email notification that someone had responded to my thread.
But yes, I've tried a ridiculous number of things. And before this, booting up the Nook from a dead battery was a real hassle. It took a solid 10 minutes of trying different power button/N button/boot screen button presses. Even before the battery died, it's been a bizarre, and immensely frustrating, quirk of having CM 12 on my Nook. And the internet seems to be largely resource-free on anything remotely related to this topic.
Hi, near-total novice here, but I've just put CM12 on my Nook HD+ and everything is great except I have the same power down problem. Both Reboot and Power Off result in my Nook rebooting.
