[Q] How to fix! Fire will not reboot. "green" power button led stuck on

Today, after I was done using my tablet, I shut it off and noticed it turned off but the green led portion of the power light is still on. Tablet will not respond to power on/off commands, nor can I gain access to it via adb.
I updated to the Energy™ -.¸¸.·´¯ ICS CM9 Kang ROM several days ago, there were no problems there as I have been using the rom for a couple of days now.
All I did was hold the power button down, select "Power down" option came up "this will shut down your tablet" I selected "ok" and that was that.
KFU shows it as offline, as does adb. Windows does not detect the device.

Mine had a similar experience, using AOKP ICS, I powered it off and about 18 hours later I tried to turn it on and got nothing. Turned out the battery was just dead, I think it may have locked up while powering down and killed the battery. I would try a few things:
1. Hold down the power button for 10+ seconds and see if you can get it to do a hard shutdown.
2. Plug it in to the charger and see what happens.
3. Leave it alone for a while and hope the battery dies and it may start up after that when plugged in.

I kind of feel stupid, why is it with technology us geeks start troubleshooting by skipping the simple solutions, like "is it plugged in" well today, holding down the power button for 20 seconds fixed the problem. She booted up and everything is back to normal.
Appreciate the fast reply!

Major issue with my N7

Ok everyone I am having a major problem with my N7. This morning I noticed it was out of power so plugged i tin like normal, then I went to turn it on got the Google logo then it went to the Nexus logo. And it kept cycling through the nexus logo for hours and will not turn off. Whenever I try to turn it off it just restarts from the beginning. Now I didn't buy my tablet from the play store so I would have to go through Asus for a warranty replacement. Has this happened to anyone else in the past?
Some info. Stock, unrooted, locked bootloader, stock 4.2

Well this never happened to me before. Did you try removing the battery?

Well, to start, unplug your N7 from the power source and hold the power button down for about 15 seconds, this should force it off. From there, turn it back on and let us know what happens.

I don't see that you have tried holding down the power and the volume down. This should get you a hard reset.
Here is a short topic where a power and vol down worked for someone where a straight power down did not:
http://rootzwiki.com/topic/30101-reboot-tip/
it's the last post (#6)
Rather than trying to run the battery down, which is not all the way down when it shuts off and would take a long time to discharge just sitting there, you could pull the battery if you feel comfortable opening the case. It's not glued or anything and the battery has a ribbon connector.

So its in a boot loop? Reflash the image with Mskips toolkit option 9 after booting into fast boot mode. If that isn't the problem then do a warranty return. Not sure why you're stuck in a loop.

[Q] Nexus 10 wont turn on.

I placed my nexus 10 on charging yesterday, and after a while (2-4 hours later) when i came back, i found the device to be turned off, I tried the power button in all the combination with volume buttons, but still no luck (even held the power button for 3mins) I searched online, and couldnt find any help on other forums. Some said to keep it on charging overnight and then try powering it up. But still no luck.
I dont get any notification when i connect it to charger, although when i press the power button while connected the screen lights up, and battery charging sign shows up.
Any help would be greatly appreciated.

So you cannot even get to the recovery?
You ether over charged it (very unlikely to happen) or you have a faulty N10.

No, can't even get to recovery. But i have been using the device for over two months now, nothing like this ever happened. What about the charging sign when i press the power button. It might be some kind of a sleep mode or something, no?

Could be a bootloader corruption, software issue, hardware issue or some part of the hardware "thinks" that it is still on when it is not causing it to not switch on.
Have you noticed any issues before it just came off like extreme overheating?

Well, yes the tablet was getting overheated after a long session of hd videos, or games, but that use to happen all the times.

I believe this is normally called a "Sleep of Death" or sometimes "screen off death". Hold power + vol up + vol down at the same time for 5 seconds and you should boot into fastboot. From there hit the power button to turn the tablet on. Then go about finding a better ROM/kernel combo that doesnt give you this problem.

You just need to press power and volume down to enter the bootloader.

Try press and holding the power button for around 10 seconds and then try powering it up again.

Are you using the charger/cable that came with your device?

Its working.
Weird how it was taking any input from the power button though. I kept the tablet on charging over night and i tried turning it on in the morning and it worked.
Thank you all.

I've had my Nexus 10 for less than a week, and this morning I encountered this problem. I was working on setting up syncing through an app called FolderSync and SugarSync. Syncing of one of the folders seemed to go into a loop. The device locked up completely a couple times. I got the process running again and left it running while I went for a workout. When I came back no way could I get it turned on.
I had tried all the things suggested here before checking here for help. I'll try your "solution" of leaving the device on charge overnight. If I can't get it going tomorrow morning I'll return it to Staples, where I bought it.
I have an iPad and have never encountered anything even close to these problems. Bought the Nexus 10 specifically to run the Vim Touch app for Android. The only Vim app for the iPad is horribly crippled.
Sounds like this thread pretty much exhausted the possibilities by the time epicbearman discovered his "solution," but if by chance anyone has any further suggestions I would be grateful.
Thanks,
Eric Weir

I had the exact problem as the OP and none of my chargers worked. I then googled and found someone that said to try to charge via their PC USB instead of the wall charger. I left it plugged into the USB for a couple of hours and the charge went to 4% ( so it must have been very dead ) and all is well.

I charged it via the usb charger, and connected it to my pc overnight. Try doing that.

Take off the back and disconnect the battery and reconnect it

Thanks. If I'd gotten this in time, I suspect it would've worked. But when I couldn't get it started after trying everything else and leaving it on charge overnight, I returned it to Staples.
Will order a Nexus 7 from Google. If I can get Vim Touch running successfully---my reason for wanting an Android tablet---and I find the screen to small for heavy writing---I want to get by with a soft keyboard---I'll order another 10 and give the 7 to my daughter.
Thanks again,

Please Help! LG G2 Won't Boot Up

I had rooted my dad's lg g2( D802) and installed twrp using an app named autorec as it was recommended by many people in the internet and had very high ratings and downloads in the play store. Everything was fine for a few weeks till I noticed that the app had an update. So I flashed twrp again from the app hoping it was a newer version and it said it completed the operation successfully. Then I just used the phone for sometime and after that I switched off the phone to enter the recovery. After it switched off, I pressed the button combination for entering the recovery but nothing came up. Then I attempted to just boot the phone and kept pressing the power button but nothing came up. I even kept pressing the button for upto a minute to hard reboot it in case it was just a case of hanging but nothing came up.After that, I plugged it in for charging and attempted to boot again. After I kept pressing the power button for about 30 seconds while charging, the led blinked red 8 times, paused and repeated itself as long as I kept holding the power button.
The problem is that it even the screen doesn't turn on.
I searched for this issue and saw that many others were facing this issue. I tried the following solutions given by them which did not work:
1) Holding the power button for a long time
2) Keeping it for charging until it's full but nothing comes up and the phone got heated up very much untill I stopped it a few hours later.
3) Removing the back cover and detaching the battery power cable from the phone after after waiting for sometime, reattaching it.
My dad showed it to the lg repair centre but they told him they need to replace the whole board which is very expensive, especially considering that it is a 2+ year old phone. My dad is very angry at me and probably won't let me touch his phones ever again if I don't fix this. Please help me.
Thanks in Advance
Edit: the charge was at 45% when I switched it off. Don't think it is because of low battery

With the phone pluggged into your computer, does the computer recognize the phone? And if yes, what does Device Manager report it as being?

more info... what variant? phone does not boot.. can you press vol up then plug phone .. does download mode works... stay calmed this can be fixed..:fingers-crossed:

I haven't tried plugging it to the computer. The way to enter download mode is holding the volume up button right? Thank you for the suggestion. I'm away for a few days but I'll tell my dad to do so. I'll post what happens then. Variant is D802

OK I told him to do that. When he pressed the volume up button and then plugged it to his computer, 13 new partitions showed up in windows, and it is telling him that he needs to format the positions to use it. But nothing is coming up on the phone

Do NOT let Windows format the partitions(!)
Use the SRKTool instead to unbrick from qhsusb_bulk mode:
http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076
Afterwards use LG Flash Tool 2014 to flash the KDZ for your variant:
http://forum.xda-developers.com/showthread.php?t=2432476
It's better to let the battery charge to full first. Shut down the phone by holding PWR button for 10 seconds, then plug charger. It should work even in bulk mode.

Did you try these simple things...
shutdown phone keeping powerbutton down.
Start pressing power button & vol down....when you see LG logo for couple seconds. Release fingers and press vol UP and vol DOWN, same time. No power button.

But the problem is, even the screen doesn't turn on while on download mode. I'll surely try out the unbrick tool but will it work since normally, the download mode screen comes up. That thing is 760mb. I think it'll take some time for it to finish. (Ultra slow internet connection )

The lg logo doesn't come up when I do that. If fact, even the screen does not turn on

OnePlus 6T Won't Turn On

I just encountered a very strange and worrisome issue today. I successfully rooted my OnePlus 6T and installed Magisk with TWRP following these instructions.
After reinstalling my apps, installing the AdAway apk, and rebooting (using the system dialog) after I was prompted to, my phone refuses to start.
The screen is all black with no signs of any activity. I tried holding the power button for 10+ seconds in various combinations with the volume buttons. None of them worked. The phone is definitely not battery dead because I clearly remember the phone was plugged into my computer and at 83% at the time it shut off. I hardly believe I bricked my phone because the rooting process was 100% successful.
Any help would be greatly appreciated.

Plugging in your phone have any signs of activity? Might be in qcom mode. Worked for me to hold power and volume Up for like 30 seconds.

I've had this issue a few times, I was always able to get it to turn on by holding vol up + power for an extended period of time.
