Hold the Power button and the home button at the same time for about 10-15s, and it'll reboot.
that worked, thank you.
So I used my nook tablet all day yesterday and this morning. I put it down to goto lunch.. came back and noticed my wifi was not on.. I checked settings and it showed "Wifi turning off" and it was grayed out and just stuck.
I've seen this before with other android devices so no biggie. I powered the unit off.
Now it won't turn back on. Holding the power button now for about 20 secs and nothing.
The battery is at like 80% and I even plugged it in to see if it helped but no good.
I did root it at 1.4.0 and used the Block OTA method with titanium backup but nobody else seems to have a problem.
Is there a way to boot in recovery or something ? Perhaps a trip back to B&N will be needed.
Ok.. holding vol down + power for around 8 secs got it back on. Weird
i have noticed this a few times. Not sure why but never lost anything

His happened to me once and I don't know what I did to get it back on. Glad that I now know, thanks.

I had a similar problem. I couldn't get the tablet to turn on. I discovered in a Kindle Fire forum that you could get the Fire to start when stuck in the off position by holding down the power button for 20 seconds. I tried that with my Nook and it started right up.
Thank! That worked! I was having the same issue. Said Wifi was turning off and all went blank and couldn't reboot. You gave me the answer.
Cheers.
I have had the wifi "turning off" issue. Rather than turn off the nook, I used the menu that you get with a long press of the power button when you install either ROM manager or titanium backup, can't remember which. It has rebooted every time without issue.
The Wifi issue is a known problem. You can set the wifi to stay awake when on the charger and this problem wont happen. Add the power widget so that you can turn the wifi off when not connectwd to the charger. This combo fixes the wifi issue. When your Nook experiences a kernel error it will appear as if it is off but if you hold it at angle, you will notice backlight is on. Just hold nook button and power and it will turn off...then power to reboot rom.

Actually, it's happened to me twice while I had WiFi set to never sleep when charging.

I rooted my Nook Tablet and it worked fine yesterday. Now it won't turn on and isn't recognized by my PC. I hear the windows alert when a usb device is connected but when I try to do anything via adb I always get 'error: device not found'.
I tried doing adb get-state and all I got was 'unknown'
I tried booting into recovery via holding the power button + n for various amounts of time, but nothing happened.
Does anyone have any ideas? It was working fine yesterday and I haven't changed anything on it since I used it last.
Hold the power button down for about 10 seconds. let it sit for a minute, then hold the power button for another 5 seconds or so and release. It should boot up. (assuming your battery is charged)

I had to do a reset (power button + Home) twice so far. Each time it happened after I left the tablet to recharge overnight. It did not turn on as it normally does when you unplug the charger.
I must admit that the (power button + Home) reset does not seem to be cut & dry. The routine quoted above worked the first time. The second time, I tried it several times then finally I tried the pwr button by itself and it went on.
Mine just did this Power and vol down got it running again.
I was messing around with the wifi tether app built into the custom ROM I'm using (hatka 3.0), and suddenly my phone froze and now the display wont come on. When I hold the power button all 3 buttons at the bottom flash on and off.
USB reads it fine, adb as well.
Keep holding power down a few seconds after the buttons flash and it should reboot. If not, also hold volume down and you'll reboot to bootloader and can enter recovery that way and reflash if necessary

Neither of those worked. If I hold the power button, the 3 buttons will flash as long as I hold the button.
What happens if you keep your phone plugged in to the wall and you try to reboot/boot into the bootloader?
Also worth a try using adb to reboot into bootloader
Did you try removing the battery for 10 minutes ?

Plug the phone into your computer, make sure adb is working by running the command " adb devices"
If your phone is recognized type "adb reboot bootloader" and see if you can get into the bootloader that way.
Otherwise, I would keep it charged and try to get it to power down by holding power for about 15 seconds untill it powers down.
If nothing else works I would try removing the sim and try restarting that way.
Maybe even let it die then charge it up and try powering it on. If none of that works I would say you may have a fried display.

I have been in similar territory a few times. The holding down power button until 3 icons start flashing WILL work- the time held will vary GREATLY! from 10-15 seconds to waaaay longer, keep trying, multiple times if needed. It will eventually reboot. You may need to hold the down vol button to get into fastboot then recovery so stay alert when reboot happens-it usually does when you least expect it. All of a sudden, a black screen then you need to hold in the vol button to get back.

It's a non removable battery.

i got s3, suddenly it started to reboot itself all the time, what i see is only the samsung logo and then black, and samsung again.
the funny thing is that when i put the battery in, it automaticly start with this loop.
during the loop, when i press home+volume up, i can see the cwm screen for two seconds, and then it reboot again.
if i press home+voulume down, i see the warning in the stock recovery, but when i press volume up, nothing changed, and eventually after two seconds it reboots again.
i tried to connect it to my pc, but it dosen't show it in device manager, and have no indication that i connected it.
also, when i connect it the charger, i see circle, and then a battery for a brief second, and then the circle again.
is it simple hardware problem (stuck power button? even though it seem okay, but it may explain the automatic turn on), or half SDS?
anyway, are there any recommondations? i have'nt flashed it recently or anything like it.

as i wrote before, i can enter to both recovery modes (volume up or volume down) for something like two seconds, i can't do anything in it.
if i try to get to download mode (home and volume down) i see the warning, but either i press volume up or down, it reset itself.

the regular, about flashing custom roms, if i want to continue press volume up, restart, volume down.
either way, it restarts.
any way it is the power button stuck in 1 mode?
If phone starts on battery insertion, before you push the button then yes, power button is shorted out.

Try leaving the battery out overnight/long time, it helped when I got my phone stuck in a bootloop. But that was due to oc/uv...did you try something risky, causing it to bootloop?
no, it was in regular use, nothing risky.
yesterday i dissassembled it and checked with multimeter, it seem that the power button shorting the circuit, so i ordered a new one, going to be a surgical operation...

I am on stock ATT rom. Since this morning, every time I unlock the device (I didn't enable pin or fingerprint, just swipe to unlock), it will suddenly turn off within few seconds.
As long as I stay at lock screen, it will not turn off at all. otherwise it will just turn off by itself. There is no notice saying the phone is turning off, It just go directly to black. I can still go to stock android recovery, I can charge it.
Any idea?

The phone actually powers down? Where as you have to hold in the power button to turn it back on?
