I've looked through the threads and on the internet trying to resolve the following issue with no luck:
Sleep of Death occurs (SOD) (i.e. must restart tablet by holding in power button after tablet goes into sleep mode). This occurs while either plugged in or on battery. Sleep of Death occurs faster while on battery.
I have tried Captivate Keep Alive and REGPON wifi KeepAlive. REGPON keeps SOD from occuring longer than Captivate, but SOD still ocurs. WiFI appears to be on when this occurs.
I am using CM7 (2.3.3).
Any ideas on what I can try? This is frustrating.
Thanks in advance,
Paul

If you are overclocking, set the minimum to 450 MHz. What works best for me is to enable volume rocker to wake in the settings. That way I use the volume button to wake the tab. Never had a sleep of death after that. I am using Icewyngs CM7 for BL 1.2.

I keep it on sleep mode and the next day may battery is fully spended can anyway tell me why or how to prevent this?
Thats a known problem (just in the newest firmware)
I would install Urukdroid
No it is not.
in 100% of the cases an App is holding the Archos from going into deep sleep.
Just check that wifi can sleep, no Sync is on, mail, facebook or other inet apps are not holding connections.
I usually just keep it in Airplane mode, and only turn on the WiFi when I need it. This has helped with the power use problem.
I tried setting it to deep sleep, but I found that it would invariably crash when asleep (or when waking up--I don't know which).
I just turn my wifi off and put mine into Deep Sleep. I can leave it for days and the battery only drains a few percent (usually ~1-3% per day).
Some app must be waking your device, and causing the drain.
Installing UrukDroid is not the answer to all problems. I know some people here seem to think so, but there are bugs there too.
I'm not trying to knock UrukDroid at all, or the work that Sauron has done, but just switching your OS is not the best answer.
my 10.1 seems to have decided it doens't like to sleep. I am running Task 650s ROM but it doesnt seem to be impacting anyone else. Does anyone have any ideas why the table wont sleep?!
I know I have provided a LOT of background here... but all I currently have is that the wifi stays on and therefore the tablet stays awake (note the screen turns off though). The battery usage shows minimal screen on events but continual wifi/awake time. I checked my running services and didnt see anything out of the ordinary.
Any help would be greatly appreciated -- this daily recharge bs is kind of annoying.
BetterBatteryStats might point to the culprit.

Thanks for the link -- however the app doesn't explicitly point to any one thing causing 'wakelocks'. The only item showing continual use is the WIFI connection. I am turning wifi off for now to see if it allows the tablet to sleep.
Do you have any apps possibly running in the background that could be keeping it awake?
Please use the Q&A Forum for questions Thanks
Moving to Q&A
No apps running that should impact it -- I just rebooted from CWM and it seems like its staying asleep when the screen is off (although wifi is registering as consistently on even when the screen is off -- is that normal?)

Yes, its normal for wifi to stay on even if the screen is off. Unless you have an App like Juice Defender that turns it off.
Hmm, Well it seems like the CWM reboot did the trick -- the tablet is retaining charge and sleeping again. I wonder why that worked when a normal reboot didnt... odd
Thanks for all your help!

Glad you got it all worked out.
Wifi during sleep is a settings issue. Go to Settings -> Wireless -> WiFi Settings -> Sleep Policy.
I just started having the old wifi problem. I wiped the device, reinstalled CM7 with CWM, and its come back, th wifi settings freeze up, and i cant get a IP address or connection via wifi.
are u restoring the settings using any apps ?
Same. Just all of a sudden, my wife and my tp just stopped connecting to the wifi. Laptop and phone connect fine. Can't be a coincidence? Tried resetting wifi...tried going to airplane mode. Next step I guess is to reflash.

did you try to go into WiFi settings, "forget" current WiFi, turn WiFi off,wait a few secs' then turn WiFi back on. Once the WiFi connection is recognized you type in your WiFi key and it should connect again. Happens most of the time on mine in cm7.

I have the same problem, and I have to perform the fix action you described to get the WiFi back up and running.
I use Regpon from the market.
Never had any WiFi issues.
I have wifi problems, if I boot into webos and then back to cm7.
"Forgetting" the current wifi ist the best solution and works till a next boot into webos, so I stopped booting into WebOs.
No need for an app like regpon, they keep the wifi all time connected and disbale deep sleep, too battery intensive.
I'm using Tasker to turn Wifi off/on then my display turns off and on, because default powersaving options don't work.
Try This:
Settings - Applications - Development - Device Hostname
Change it to something shorter and simpler like Touchpad or something

I think you are missing the point.
Regpon avoids deep sleep thus keeping WiFi on AND avoiding deep sleep SODs meaning no toggling or switching of any kind, at least for me.
I don't see any appreciable battery trade-off either.

You're right, if you have SoDs, but if not why avoiding deep sleep? I don't have any.
Surely I can let wifi all time on, but have no reason to waste my battery.

once wifi is on it stays on here, doesn't go down on sleep either. it's only when I boot that I have to do the forget excersize to get it back.

yep, I tried every suggestion in the book, none of them helped so far.
Hey everyone, I seem to be having issues when using wifi. When home I try to use wifi and it connects and seems to be working fine. After a while when sitting idle everything will just stops working. The phone itself seems fine, but i'll stop getting email and anything that uses internet stops working as well. To get things to start working I have to either toggle wifi or just turn wifi off.
Any ideas?
Check your battery/sync settings. If you changed to normal sync/wifi/etc will turn off after 15 minutes unless you manually change it.
Even at Performance power setting, I found my Wi-Fi would still go to "sleep" after sitting for a while. The culprit I think is the "Sleep Mode", which is enabled by default. Changing that to manual or even off should solve the problem.

You have to go to Advanced under WiFi Settings (Hit menu button) and turn always on.
Mine has the same "problem." I'm ok with WiFi turning off to save battery. I haven't been able to reliably get it to wake up.

Didn't know that, thanks!
Good call, man. I think that's why mine randomly shuts off too! Im gonna start setting sleep mode for when I sleep every night.... It says it shuts off networks when screen is off but when I turn it on, WiFi is on right away...when you turn WiFi off it takes much longer than that to power up so I don't know what networks its shutting down lol

No problemo!
It seems that upon turning my screen off my phone will not enter deep sleep properly, sitting at around 30-50% of the total time. I have narrowed it down to what seems to be a wifi issue.
Phone Specs:-
Build: CheckROM RevoHD v4
Kernel: SpeedMod k2-18-test13
Baseband: KI4
When I completely turn off Wifi and 3G I experience very minimal battery loss and over 95%+ deep sleep.
Turning on JUST 3G also gives me 95%+ deep sleep with slightly higher battery loss then disabled.
Using Wifi only causes me to lose A LOT of battery life (about 1 % per 5~ minutes, screen off of course) whilst having about 30-50% deep sleep if even.
Yes, I have tried turning off syncing, background data, GPS, locations etc. with 3G and Wifi seperately and there seems to be no change at all. I have tried several kernels (mostly speedmod) and they haven't seemed to fix this issue.
This leads me to assume that my current app setup is irrelevant as I used the same setup when comparing Wifi On and Off/3G.
Has anyone else encountered an issue like this? Would really appreciate any input that will go towards solving this problem. I will try completely different kernels to see just what exactly is going on until someone can help me out with a fix.
Thanks in advance.
It could me that your router is causing the problem. What router do you have? It could also be a modem problem. Try changing your modem and see if that helps.
Changing kernels won't help.
I'm using an RT-N15 Asus router (asus.com/Networks/Wireless_Routers/RTN15/) using WPA2-Personal security. I might try changing the mode, which one do you suggest for the setup that I have? Have never changed modem since stock.
*EDIT* I tried a few different modems and didn't seem to help at all. Tried Dark Knight 2.3 kernel and same problem. I guess I'll have to try another wifi network to see if it is the router.
Do you have Wifi sleep policy set to 'never'? Make sure it is.
settings>>wifi >> wifi settings >> menu >> advanced >> sleep policy >> Never
Yes it's off. I've been playing around with it more and finally got it to deep sleep properly with Wifi on but the battery went from 48% -> 21% in 7 hours while being 90%+ in deep sleep. Android OS came up at 59 mins, 53% battery usage.
