I've already posted this on Android Central forums but have had no luck so I figured maybe someone here can help.
So this just happened to me last night. I was low on charge somewhere less than 15%. I plugged in my phone and turned it off with Wi-Fi and CDMA radio on. I turned it on a couple minutes later and it booted up in airplane mode. That's okay cause I can just turn airplane mode off. I do that and everything works fine BUT my lock screen still says "Airplane mode is on". If it matters I'm using the rooted Froyo 3.29 build that was released a little before the OTA came out.
Noticed another thing. When powering off it's going to airplane mode right before the screen turns off. I can see my Wi-Fi bars disappear and the airplane show up. Functionally it's fine but it kind of sucks I keep seeing the airplane when I press the power button even though it's no longer in airplane mode.
Has anyone else had this problem? Any possible fix to this?
EDIT:
Sorry. I realize this should be moved to the Q&A. Any moderators out there please move. Thanks!

For everyone using the Xoom data plan and placing it in airplane mode, it may not shut it down. 3x over the past week I have been traveling on the train with my Xoom in Airplane mode and wifi on (was afraid of data usage). Well I was getting "Dings" for email. When i looked, it had full bar on the VZ network and was still in "ON" mode for airplane. Switching Airplane off and on rectified this issue.
Has anyone else experiened this? It is just something to be mindful of.
I returned my Xoom (VZ could not get me hooked up to my VZ) and am getting the wifi one next week.
Fortunate for me I haven't had this issue
Ii have my 3g off all the time,... only turn it on when needed
Since airplane mode is actually supposed to turn off wifi as well, I suspect turning wifi back on can sometimes trigger the radio to activate since you technically are no longer in airplane mode.
That said, if you are normally in a good wifi area I would recommend setting the wifi sleep policy to never if you can.
I'm gonna bet anything the bar you saw was actually WiFi and you'd just inadvertently associated with an open WiFi connection while on the train.
FWIW, I've never found my CDMA radio set unintentionally out of Airplane Mode (where my Xoom stays 95% of the time).
any solution to this? happens to me pretty often when i let it sleep for a while. it helps if i don't leave wifi on, but sometimes even with it turned off i'll have to reboot. and the battery tends to drain a lot when it happens as well
The same here, but i solved (kinda) by setting the tablet to Airplane Mode before "suspend" ...
Seems to be something on the area of Hardware Related issues.
That's why maybe they set a reset button ... have never seen any of those on other tablets so ...
Mine is always in airplane mode.
Didn't even realise there was a reset button I just hold power for10 seconds then power on
So a few weeks ago, I noticed when my nook reboots, it does not automatically turn on the wifi. I have to do it from the settings area. If I do it from the notification bar, it doesn't work so hot. I put on green power today to see if that would help me flush out the issue and, even though wifi is on right now, green power is insisting that the airplane mode is on. If I set airplane mode on in settings, it does turn off the wifi and it sets in a state where it says "disabling wifi connections". It never toggles over to a check being there for airplane mode and giving me control. I have to back out of the settings and come back. When I do, airplane mode is not visibly listed as being on. I can turn the wifi on and green power insists airplane mode is on. If I reboot, sure enough, no automatic wifi.
Any ideas? I've got CM-7 08042011 running.

Magnetron1 from the cyanogenmod forums has a way to avoid this. Go here and find the most recent nightly he modified. I believe it's cm7 nightly 251. He named it cm7 nightly 251m*. That did the trick for me. I've been downloading my nightlies here ever since the airplane mode issue appeared.
Download android assistant from the market and then uncheck airplane mode.

This worked. It had an airplane icon down in blue and when I clicked it, green power finally has said airplane mode is off. Hopefully wifi will be on by default now when it reboots.
Edit-confirmed working. When nook reboots, wifi now defaults to on again. Awesome!
Running a Nook Color with CM7.1 stable. Kind of an odd issue here, I have two different Bluetooth GPS devices, and when they are paired to the Nook and I turn my screen off and then back on, it loses the connection. The only way to reconnect the devices is to restart the Nook, as it fails to connect after the screen is brought back up. I have found that if I have the Nook plugged in for power, this issue does not happen. I have tried multiple GPS apps, reflashed CM7.1 multiple times, but still have no success unless I have the Nook plugged in, or I just ensure the screen doesnt go to sleep.
I really need this to work, as I'm using this as a pilot, and I can't have the screen on the entire flight as it will drain the battery quickly. I swore it used to work before, but I know I had issues with it, and maybe now realize what was causing those issues. On a side note, my friend has also tested everything I have done, but his works consistently and reliably regardless if he leaves the screen off, or turns it on and off repetitively. Hopefully someone may have an idea!!
Thanks in advance.
So noone has any thoughts or ideas at all?
Well seeing as it doesn't happen when your plugged in that would make me think that it has something to do with the fact that WiFi turns off when the screen is turned off. The Bluetooth and WiFi are on the same module i do believe. The default setting for WiFi is to stay on all the time while plugged in and turn off when the screen is turned off while on battery.
My suggestion would be to turn the WiFi to stay on all the time and see if that changes anything. Go to WiFi settings --> menu --> advanced --> WiFi sleep policy -->never. That would be my suggestion, hope that works for ya!

That's what I was thinking too. It seems that when NC goes into deep sleep Bluetooth will lose connection. By removing deep sleep you should be able to stay connected, although your battery will drain faster than with deep sleep on, it should have a better life with screen off than on.
Well I appreciate both of your responses. However, I should have mentioned that I do already have Wi-Fi set to always stay on/never sleep. Any other suggestions?
Something very curious has happened the last week or so.
The Wifi stays on, even when the phone is in sleep mode. It is evident when I unlock, the wifi symbol on the status bar doesn't bleep (reconnecting), but stays solid (connected). Of course that could be an operating system displaying error, but it's not; functionality is there, wifi stays on, device connected to the internet. And I'm not talking about the short amount of time that the wifi stays on after locking the phone. I'm talking I'm receiving notification etc as if I was using data.
I noticed it when, after waking up in the morning, I realised a massive battery drop (from 65% to 27%) overnight, although I keep my phone on airplane mode at nights.
As I haven't recently used any mods, regedits etc, and I haven't updated or flashed any rom (btw I'm on debranded stock 8107, with KK2), I can attribute this weird but very interesting behaviour to 2 possible things:
a. I installed some app, possibly homebrew, that somehow (even the dev didn't know about that) keeps running keeping wifi awake under lockscreen
b. Maybe it's because I'm on Airplane mode. I kept on being on Airplane mode from the moment I noticed it (as I have input my SIM to another phone). I should note though that there is a sim in the phone, I'm just on Airplane mode. Is that a known feature? Wifi stayin on under lockscreen on Airplane mode? I don't think so, as I would have noticed all that time (I keep my phone on that mode a lot).
That behaviour has persisted after soft-resets (reboots) and battery charges. The only hardware change I made the last week was using a non OEM replacement battery (the ones that reboot the phone when connected to the charger). But I'm using the original battery.
I should note it consumes about 4% of battery life for every hour, quite viable.
thats weird, but to some ppl, like me, i'd be happy if this happens, would love wifi staying on in sleep mode.
but, the opposite happens with mostly everyone
Even more curious thing that I found out today. When the phone is SWITCHED OFF, and wifi was on before switching the phone off, I have battery drop (almost the same as if being switched on with wifi on, around 3-4% per hour, in my instance from 43% went to 11% when I switched the phone on).
I don't know if the (original) battery has been messed up, so the battery index is not reliable (the reason I bought replacements was that in a span of 1 month, I was not treating it right, a lot of charging, heavy operation simultaneously, resulting in excess battery heating etc), or for some reason the use of the fake battery messed up the software part (both battery metering and WiFi stayin on)
I'll do so more testing and I'll report. Has anyone tried to go to Airplane mode and switch on Wifi, to check if it stays on under lockscreen?
It stopped today... weird!
... And it happened again, this time I think it might have been triggered by Audible, I might make a video as a proof.
EDIT: I was making that video, and realized on cam that it stopped happenning, and then I realized I had flashed beforehand the KK4 firmware. What a douche! If it happens I'll try to capture it on camera
When the data connection is OFF (like when you activate airplane mode) wifi remains connected even when you lock the phone.

No that doesn't normally happens, unless you have an app running under lockscreen and using WiFi (like a music streaming app)
