Windows Mobile 6.1 ... Screen not going to sleep?

Just upgraded to Windows Mobile 6.1, and for whatever reason, if my phone is unlocked and idle, it no longer goes to "sleep." Instead of the backlight turning off like in WM6, the backlight goes full brightness and displays a white screen. Has anyone seen this before? Any workaround/fix?
Thanks!

Sounds like you got the wrong display driver for your phone. What phone and what ROM are you running ?!

I've had this problem before!
It happened when I was playing with the power management settings in the Registry. I found if I then locked my phone (e.g. long press of hang up button), the screen would time out and go completely white on full brightness.
To fix it was easy enough - just change the power management reg keys.
Once I screwed them up soo much I had to do a hard reset so watch out before playing.

Mine has been doing this also, I believe it may have something to do with the Light Config option in CeleTask. Will test more

And what should I change the power management reg keys to?
Could you give more detailed instructions, including which keys to change, and what to change them to?
Thanks!

Yes I believe so too because it only happens when I use the low light option as well.

first off try....
go into power management under settings.
1. backlight time out on battery should not be set to never.
2. backlight time out on AC could but it still will turn off after the time period you have set for the next setting.
3. Display timeout- will turn off the display off completely after the time period set here.
1 and 2 low dim the screen prior to setting on 3
turn lowlight off... it hardly ever works. lol

Power off backlight?

Hi!
I am looking for tweak or application which turns off backlight - not just dim the display to lower level after some time.
I want to completely turn off backlight to 0% and when the screen is tapped the backlight is on again.
Any solution for this?

ya core player does that...even tcmp player

If in Setup>Power supply>Advanced click on "Deactive device when not run for"
this setup turns off all display lights after minute that you set and in the same time blocks all keys.
To reactivate the handheld just press the power button.
I find this setup very useful.
Exscuse me because I have not an english ROM and I don't know if I have made a right translation of commands.

Thanks luigug, but that is how I configure my device from start.
The point is that I dont want to press power button again to activate device, just to tap on screen and use slide to unlock application.
Any other clues?
Thanks

you are right, this is a major design mistake in wm6 "features", and all wm6 devices suffer from it. This behaviour actualy make the native windows Device lock function unusable. Also, wm is much more stable if you never suspend it, and battery performance is almost the same.
I even searched for a wm5 downgrade rom for my eten m800 (wm5 does not have the dimming "feature"), but without success.
I still hope someone will manage to get a fix for this to function like in the wm5 days (my mio a701 was able to do it easely). Maybe we should make a wish topic in development section ?

Possible to leave screen brightness on when charging?

When in the car, I would like my screen to stay on when charging.
I found a way to do this by going to Settings -> Applications -> Development -> Stay Awake
However the screen may stay on, but it still dims after X minutes (depending on the Time-out settings) so i cant see a thing on my phone during daytime.
I can ofcourse set the time-out to 30 minutes, but i dont want my screen to stay on full brightness for 30 mins when its NOT charging!
Anyone got an idea?
Thanks!

Setting profiles mate. You can set different profiles for when it is charging, including keeping the screen on, and when you unplug it, it goes back to normal. I've been using it for quite a while and it works spot on
Cheers
Ian

Sorry I'm a bit of a Droid newb. On my old 6,5 winmo there was a slider for brightness on battery and brightness on charge.
Is this profile setting stashed within the settings somewhere or is it an app?
Thanks for your help

Another way of doing this is to activate car dock mode when you're in the car. There are some apps that allow you to manually activate various dock modes, and I think when in car dock mode the screen stays on all the time at full brightness.
The app I used is called 'dock simulator' or something like that on the market, and it's free.

Sweet thanks. Any idea how to lose the logo?

Open settings, applications, development, and tick always on when charging, nice and easy

Yea but as already said in post 1 the screen dims.
found a problem with the dock app where it puts calls out on the loudspeaker, and you get the icon.... damn!

you can always download power manager from the market and set to never dim/timeout

Yes but then it eats the battery

Ok seriously what's wrong with you you've started a thread cos ur screen dims, get use to it! Of course if you keep your screen on your battery will die quick you can't have everything

I agree this is annoying, when you have the phone plugged into the charger it would be great if the screen didn't dim, happens sometimes when I'm reading ebooks on my phone, don't want to change the dim settings as I want the screen timeout to kick in when not plugged into the charger.

Is there any app that wont let the cpu go to sleep when the screen is turned off and wifi is running with file transfer? cuz no matter which program i try. Transfer speed always slows down to 40% once monitor off. I think the cpu is downclocked.

Sorry I thought this was a forum to help people over come issues. looks like you may be in the right place.
1. I never started the thread
2. the initial thread was started by some who has the same problem as me. This means I am not the only one with the problem and maybe it's worth solving
3. The thread was started because on power, in the car the screen dims and I want it bright as I can't see it in the sun. I want an app or a setting so when the device detects its on power it does not dim the screen.
quote from post 1
"I can of course set the time-out to 30 minutes, but i don't want my screen to stay on full brightness for 30 mins when its NOT charging!"
I know this is possible because dock simulator does this but has unwanted side effects ( phone on loudspeaker ) I know I could just fix the brightness on every visit to the car but this is a pain in the ass and I will forget to disable it and flatten my battery.
I could do this on win mo 6.5 and android is a much more flexible operating system.
Sorry if this post covered old ground but I found your last post rather provoking and I would prefer if you directed similar posts, elsewhere.
Thanks to everyone else who has guided in the right direction so far..

I have the same problem and when I asked before I got the same (none) answers.
It is one of the very few flaws I have with Android.
On WiMo I could leave the browser with the traffic site active and VISIBLE in my car charger and I could hit refresh now with android I have to touch the screen to activate the backlight and then refresh the site if I want an update.
I too just want the backlight to stay on ONLY when the phone is on external power, it can't be that hard and it shouldn't involve installing elaborate programs that consume more of the little precious memory I have left (until FroYo ...)

try an app called 'Caffine' from the marketplace its free and does the job perfectly

Thanks I'll give it a try.

[MOD] Notification led through OLED screen

I was thinking that since the OLED screen does not use any backlight, lighting up a few pixels just to form a little led blinking would not tax too much the battery.
I don't know, however, whether waking-up the phone entails significant increase in battery usage. A middle solution would be to wake it every 2 minutes for 10 seconds in order to display the notification and the let it sleep again.
What do you think?

Sounds good good but im not to sure about that... there was another post about having the illuminating back button flash, maybe both menu and back buttons.. alternating between each one with a speed setting?

i love the idea, but the screen is 'off' for a reason...
first of all i don't know if oled screens can 'burn' (meaning the pixels are still showing when they are suppost to be 'off', because they have been 'on' to long)
Also, if it means the chips that control the screen have to be active instead of inactive, your battery drain may be kinda big....

I don't know that OLED would have burn-in (that's more a CRT thing), but they might well burn out - they do have a finite lifespan.
But you're probably right, it would likely mean that the phone couldn't completely go to sleep.

well, in such a case we could rotate randomly the pixels to be lit up (as in real old time screensavers).
With regard to out of sleep battery consumption you have a point. Maybe we could just wake it up for a few seconds and then have it sleep again. In any case if we assume that the major battery draw is the typically screen, then such an arrangement might prove to be acceptable - at least in some cases.

Why not use the backlight on the menu and back button? They shouldn't use too much power or get burned?

Yes - I agree this is a very good alternative - yet I do not know how bright these leds are.
Nevertheless, I noticed that the screen is able to display a big animated icon of the battery charging even when the phone is off! (I just received it and I put it in the charger). Thus, I assume there is some kind of control of what the display shows without having to wake-up the system (at least the whole of it).
If this is the case, we could have some led like notification even when the android is in sleep!!

what you say is not necessarily true.. that icon is when the phone is off. which does not translate to being able to display something on a sleeping phone when it is on.. two totaly different issues ..

True. I will check whether it is displayed when the phone is on sleep (still off and charging). It implies, however, that the screen can be controlled (also?) independently of the OS.
(all in all the touch buttons respond / light up when touched though the phone is off and charging).

Go guys!
I'm waiting this modification to buy this phone!
I belong to you!

Up !
Very funny topic one year later !
NoLED, BLN ...
The community is very powerfull !
Thank you all

Guys, just search NoLed on market and it's already made ^^. However, following neldar thread on BLN, NoLed use about 10% more battery per hour than off screen. BLN which is found in most of the kernel ( Except damianGTO one ) use about 1% more battery per hour and turn on the backlight of the touch key. Hope this will help you

Capacitive buttons on AOKP

Hi, I was wondering if there is a way to dim or turn off the the the back lights of the four led soft keys of aokp? I can't find a way on the internets for our phone :/

Not sure If it's the same it go to settings, display then touchlight key duration. And there you should be able to turn off

Watch QBkings video of this rom, he shows how to turn these on screen buttons off in the first two or three minutes. Forget this, misread the question

There used to be an application called led hack that would turn off the capacitative buttons. Not on the market but you night be able to find the apk and see If it works

Not to be a necromancer but I'd really like to tackle this and be able to turn the backlights off.
LED Hack does not work for our device but Screen filter does, It'll turn the lights off until you turn the screen off and back on, the lights will then turn back on.
I'm not seeing anything in the logcat that gives a hint as to what the app is doing.

Any news on this?
It seems like many ICS based ROMs, not only AOKP, keep the capacitative button lights on whenever the screen is on. This causes more battery to drain and makes it hard to use as a clock radio (too bright). I have yet to find a setting to turn that off so it times out like most GB ROMs.

On any TW based ICS rom, you can select them to be always off.
Menu -> Settings -> Display -> Touch Key Light Duration

there should be a flashable zip to turn off the lights either in the codename thread or the aokp thread
