Has anyone experienced their nook will shut off where the only way to restart is to power it back on?
I am running miui.us if it matters.

Yes, it is called Sleep of Death (SOD). It happens when you have wifi set to stay on when the screen turns off. After a while the system will go into deep sleep (as it's supposed to do) but if you have wifi set to also stay on, sometimes it will not wake up. There are workarounds to prevent this, but they are usually not very satisfactory if you want wifi on. Search the forums for discussions on SOD. It affects all newer versions of CM7 including miui.us.
I have this too, also running miui.us. My solution was to set the Nook to never sleep. I tap the power button when I'm done, the screen goes blank, I tap the Nook button or power button to use it again and it pops up in a second. Wifi quickly connects and I'm in business.

Alright, I know some have had an issue with their Wi-Fi sleeping when the screen turns off. There is an easy fix to this issue...
From the home screen press menu the go to settings, from there go to wireless settings and press menu, go to advanced, you will see Wi-Fi sleep policy, change to Never.
Now you will stay connected to Wi-Fi when your screen turns off.

I so wish that was the fix I was looking for. My Wifi goes in and out with the screen off, and sometimes even on, DESPITE being Never Sleep. Only since update to 2.2. 1.6 worked fine all the time.
I am seeing on my Streak (US, WiFi, rooted with Gingerbreak and using LauncherPro) that the display time turnoff does not stick. I usually have it set for 2 minutes - I'm seeing that when the display turns off, and I then bring it back using a light tap on the power button, there is no time selected.
Anyone else seeing this?
I need some help!! My nook color (with CM7 on an SD card) will not come back on after the screen turns off. Now this isnt everytime but it happens quite often. It happens whenever the screen automatically turns off or if I press the power button to turn off the screen. Then when I press the n button or the power button to turn the screen back on, it sometimes won't turn on. I press either button multiple times and it won't turn on. I have to hard reboot it. It's very annoying.
Is it going into some sort of sleep mode? Any help is appreciated.
Change the wifi sleep policy to turn the wifi off when the screen is off, you can accomplish this by going to the wifi settings, hitting the menu button and then advanced...
I'd also recommend for general usage to install to the emmc and use the latest nightly for best CM7 stability and performance.
I'm kinda new to this stuff. Can you tell me how to accomplish the general usage to the emmc? And also how do I update to the newest build? Would I have to rebuild my SD card from scratch?
To install to the emmc just follow this guide(http://forum.xda-developers.com/showthread.php?t=1030227)
You can get the latest nightly here(http://download.cyanogenmod.com/?device=encore)
If you just want to update your sd card install all you should have to do is place the latest nightly on the boot partition of your sd card and boot into recovery(start with the nook off, press and hold the "n" button and at the same time press and hold the power button for a good 3-4 seconds, while still holding the "n" button let go of the power button) and the build should update itself.
If I update the build will I lose all my apps and configurations?

No, you wont.
After I install the newest nightly build, how can I verify it is the newest one?

This is Sleep of Death. To get rid of it forever set up two profiles in tasker one for wifi off with screen off and wifi on when screen is on.

Love Tasker, and did this in Tasker for a while, but Green Power is actually better for this specific task, even if it is yet-another-service.... It'll open up wifi (if you want it to) every N minutes for M minutes to grab email or such, then back off. And it's pretty cheap if you don't already have Tasker.
In reality, I am sure I COULD have Tasker do this too... Set a var, have a every-15-minutes process look to see if the var is set, go online for M minutes, go back offline... But I sometimes find Tasker doing too many things at once makes it get behind.

I tried green powder and still got SoD because of the constant wifi on and off in sleep. Tasker is the only complete solution I've found

True, for the NC, turning off completely makes sense.
I have an almost new Nook HD running CM10.1-20130810-Nightly-hummingbird in EMMC (just updated today).
Most of the time, it won't wake up from sleep unless I repeatedly press the power button from 10 to 20 times.
Other times it wakes up immediately when pressing either the Nook button or the power button.
Once it wakes up, everything works perfectly. This is the only problem I have.
It had the same problem with both 20130624-Unofficial and 20130719-Unofficial.
Anyone have any ideas????

Do you have a cover on it? Maybe one with a magnet in it?

Nope... no cover... I use a BookArmor case that doesn't have any magnets in it.
I have the same exact problem. I use a case with a magnet cover. Running CM 0810.

Then open the cover twice and it will be ok.

The magnetic cover issue is actually on HD+'s. I have heard of no one having your issue with an HD. Sounds like you have a defective power button. Did you have this issue on stock?

I have the HD and I have the same problem. I took off my cover/case and still experience these sleep issues. Yes, opening the cover twice is a workaround but it does not fix it.

I don't remember this happening when it was stock... but it was only stock for about two days before I broke down and installed CM10 to EMMC.
There's at least two of us out there with HD's with this problem.
I doubt its the power button as I can see the LCD flash on and off when I repeated push on the button to wake the HD.
The backlight goes on and off with black screen and without a lock screen.
Also the Nook button should wake it up but fails the same way.
Sometimes, when I remember, a long press on either the Nook or the power button will wake the unit up more often, even that fails a lot of the time.
I suppose I can flash it back to stock and see what happens....... sigh
I don't mean to get off track here, but I'm wondering about the magnetic cover issue.
I have an HD+ and a magnetic cover. I don't have any lockscreen set. On the stock ROM, it worked just fine. But, as mentioned in this post, I have to open the cover twice for my Nook to turn on.
It doesn't always take two times. Sometimes, if I set the Nook down and pick it up a couple minutes later, opening the cover once will turn it back on. Does anyone know why it's doing this?
Let me add something strange to this problem:
I can click the power button three times fast then hold it down......
.... and the Nook will wake up 98% of the time!!
Sometimes, I have to do it two or three times, but it always works!!

Mine does all the things in this thread, too. The open cover twice fix works for me, so that'll do as a fix for now. But here's another I found:
I can click the power button quickly twice, holding it in the second time. This brings up the shutdown menu. If I then touch the 'back' screen button, the screen stays on.
Hoping this might help someone who doesn't have a magnetic cover.
My HD running 10.1.3 does this from time to time. I have a Poetic case which I believe has a magnet in the cover. When it doesn't come on, if I push the Nook or the power button, the screen comes on and quickly goes out again. It may do this several times before it finally stays on. I'll have to try the techniques mentioned here.

My HD+ is running cm11, most of time, the wake up by opening the cover works perfectly, occasionarily, I need to open twice, didn't have other wake up issues.
My new HD is experiencing the same problem. I'm on the stable 10.1 cyanodgen hummingbird release. I would sometimes have to press the power buttons on the side or front repeatedly to wake it up. Before I had the "slide to unlock" lock-screen on but after I unlocked the screen..swipe to unlock..it would go back to the lockscreen, it would do this over and over until it eventually unlocks it. So I thought it was a lockscreen issue with the rom so I took off the "lock-screen". I would think the problem is gone but the screen just comes on for a split second and then turns off every now and then. You would have to use the home button or power button to turn on the tablet. It is annoying.
I just bought a Nook HD on ebay with a Poetic cover with magnet.
Mine does the same thing on stock 2.2.1, both before and after rooting, whether opening the cover or, with the cover already open, pushing the Nook button.
I don't think it ever takes more than three tries to wake it up, though.
Glad to find out that this problem isn't unique to my unit, at least.
Sorry to post to a 3-year-old thread.
I have been using my nook HD+ on CM10.1, 10.2 and 11 for a few months with no problems. Then recently I got a weird problem. After some investigating and testing I can consistently replicate it as follows:
Leave it idle at 12:00pm.
Screen goes off at 12:01pm. (normal, because set to 1 min)
Now if I touch the screen or press the 'n' button or press the power button at 12:02 or 12:03, the screen comes back on, which is normal behavior.
However if I touch the screen or press the 'n' button or press the power button at 12:11 or about 10 mins after screen off, nothing happens, the screen does not turn on. It feels like it has turned off, but I don't think so because I have to hold the power button for 5-10secs to "forced turn off" (no visual indication), let go then hold the power button again and it will boot up the nook like it was turned off.
I have assumed software error at first so I completely wiped the entire nook, including /system, /data, /0, reinstalled a fresh M6 or M8 along with pagapps, but get the same problem behavior on the fresh install.
I'm out of ideas and suspect a hardware fault of some kind that may not be fixable by me. Anyone has the same problem and found a fix?
Edit: additionally, the 10mins is not fixed. It could be 10 mins this time, 20mins at another time. Also if I plug in the charger at this point of time, the led is a steady green.
Edit: more googling yielded the term 'sleep of death' that have somewhat similar symptoms. Still no solution yet.
Do you have a case with a magnetic cover? If so the solution is to open the cover twice.

I don't know how to fix your problem, but it is caused by your device going into deep sleep. The device is designed to enter a very deep sleep mode after 10 to 15 minutes of inactivity. This is to save battery. For some reason your device is hard to wake up. You might try playing with some of your settings, like whether wifi stays on in sleep mode, etc to see if that helps. The HD+ does not suffer from SOD (Sleep of Death) like the Nook Color used to.

Wifi may not stay on in sleep mode anyway even when set to always on - though I've not noticed this problem since M8 on the nook hd+, my phone does still have it. Perhaps enabling it will help due to wakelock on the cpu (keeps the cpu in use during sleep).
Noticed at rare times in the past that the screen could take much longer time than normal to come back on. It could just be hard to wait long enough. Don't know how long you were waiting but I've done the same thing as well as waiting for it to finally turn on.
If your using a lockscreen, you could try disabling that completely. Sometimes, there are bugs there.
In case anyone else has my problem, my workaround is to install wake my android pro so that it remains in sleep and never goes into deep sleep.
