At times Backlight doesnt light up again - why?

Perhaps someone has an explanation why my backlight doesnt light up again when a button is pressed?
From time to time, the backlight goes dark and even though I am pressing buttons, screen, power button, etc, the backlight doesnt come back on. I have to search for the backlight adjuster (in the dark) in order to switch the light back on.
I have wisbar advanced and SpbPocketPlus installed - might that effect this somehow??
Thanks for any advice!

i have exactly the same problem and don´t know a solution. ;-(
Wisbar Advance 2.6.0.1 is installed, SpbPocketPlus not.
I think it comes more often if i use the camera, but it is not reproduceable...

I've never had this problem before, I dont have wisbar installed.

You may be doing a press and hold function on your device. Quick press of the power turns it off, a long press turns off the backlight. the only way to turn it back on is to long press the power button.
also you have settings that turns the back light screen off, which may be affecting this.

This problem used to occur on the O2 XDA2i ALL THE TIME!
Just my 2 cents. Sorry, not very helpful, but defo a problem we've seen before. You hvae to go into settings to start the backlight back up.

It hasnt happened lately (actually ever I posted this thread strangely enough) but its quite embarrassing when you have to find your way through a dark screen.
I put a large symbol of the brightness adjuster in one corner (using SpbPocketPlus), so I only have to find that symbol rather then start --> settings --> etc..... its not a cure but it makes it easier switching it back on.
If anyone has a remedy for this problem, please share...

Not sure why this happens, but I fixed it using...

This app - run on your prophet, and all is back to normal. Keep a copy on your SD card...

didn't help
I tried and still use the neo backlight fix. But this fix is only for forcing via startup a longer measured time for the light to stay on.
I too have suffered with the problem of the backlight not coming on every now and again after starting up the prophet. I've had this problem on numerous roms too which is interesting. What more interesting is that even in the days of my owning a Blue Angel (Orange M2000, MDA) I STILL remember having this intermittent problem with the light not always coming on. Only way I fixed it was to simply soft reset the device. Whenever I did that and when I do it now, it stops it happening for week or so at least.
I still use the neo back light fix too as my phone has the quick light turn off problem without it. Neo certainly created a good fix no mistaking.
All the best

i had the same problem...just put the same value to the standby and backlight ...( both 3 mins on mine)...and never happened again....i think it helps...

I have a strange backlight & power-off problem on my Qtek S200:
When the backlight is switched on and I press the Power button shortly to switch it to sleep mode, the screen gets blank but the backlight does not go off.
So now I wait first when the backlight timer goes off before switching the device to sleep mode manually.
Another problem:
When the power settings is set to switch the device off automatically, it reboots when the timer goes off. So my solution is to disable the auto power-off feature.
How to fix this to the original behaviour ?
I tried the neo_backlight_fix and set the backlight timeout to the same value as the standby timeout, but with no avail.
My Qtek S200 has still the original old ROM (G4 model) and Windows Mobile 5.0:
ROM version info:
IPL: 2.10.001
SPL: 2.10.001
GSM: 02.07.20
OS: 2.10.7.25
Please help me to solve the problem.
Maybe I messed up a lot and the only solution is to install a newer ROM which is available since some time at qtek.nl.
Thanks in advance.

Turn Universal on/off by opening/closing Lid

Hi all,
I upgraded to an O2 Exec a little over a week ago from a Blue Angel.
Initially I had a few concerns about it, but thankfully I found this forum, and have managed to get a number of enhancements, from increased storage and better radio (v1.09) to being able to turn on the flash light using a hardware button. My Exec is now running faster than my Blue Angel ever did, and hasn't frozen once. I've already become quite attached to it.
One thing that I think would be useful would be to have the unit turn on when the lid is opened, and off when it is closed. In the Power settings you can uncheck the box that turns off the device if it is not used for x mins, which has the effect that the screen will come on whenever the lid is opened. However, because the device is still running the battery still takes quite a hit even though the screen is turned off, and even when you lower the cpu speed.
Is it possible to turn the device on and off by opening and closing the lid?
Cheers
Rowan

Hi, I have mine set to come on and off when you open close the lid, and it's set exactly how you have said. Power settings, and stop the device going off. And Backlight settings, stop the backlight dimming, and lower the backlight when on battery mode.
There is no "off" mode like Nokia handsets, only Standby, which is what happens when the screen is closed. (I think).

You're not really going into standby mode by closing the case, try switching on wifi or bluetooth and look at the flashing indicator LED, it will still be going whien the case is closed. Nowtap the power button to put the device into standby, no more flashing LED. The phone LED still flashes which is a good thing otherwise you wouldn't be able to recieve calls in standby.

From what I know, the Universal has no real OFF mode, only standby, EVEN WHEN YOU PRESS THE POWER BUTTON. On mine, BT and WiFi still flashes even when I press the power button or just close the screen.

Pressing and holding the power button turns the backlight off, a quick press (or tap as I said before) makes it go to standby and should turn off everything but the phone part.

Okay well weve taken a really fun detour discussing the technicalities of standby and 'power off' but lets digress for a moment back to the original topic...
Rabangus, seems the best option you have is what you were doing. The hit to battery shouldnt be that large. I gave it a try not too long ago the way you and the other member had it set up again, and yes youll definitely have to charge it every night but it was doable. But I wasnt using wifi or bluetooth either. I am surprised that using Xscaler it still takes way to much battery. I assume thats what you are using to lower the CPU.
Oh well unfortuntely thats the way it is chief.

Backlight Issues!

Guys its one thing after another!
This thing is in urgent need of a Rom Update!
The back light doesnt turn off after the specified time! Not completely anyway.
What happens is that it just dims out to a very low backlight and still stays on!
The same thing happens even when its connected to activesync on the pc!
Anyone else experience this?
Thanks in advance for any help anybody can provide.
Dead Cell.

I think that is normal behavior. If you need your backlight off while the device is still running, I think there are 3rd party apps that can take care of that. The only time I want that option is when listening to music, and TCPMP can map a button to toggle the screen off.

If your phone is connewcted to PC then it's powered and stays on low light setting when not used. But if you disconnect it from power/pc, after a specified time, the screen turns off. At least on mine. However, when listening to music the screen never turns off.

My Prophet backlight used to go completely off while the device could actually be on, pressing the D-pad could bring the screen backlight on again. It was still possible to see that the screen was on by holding it up to a bright light.
When unplugged from the power supply, my observation has been that the Trinity back-light doesn't go completely off, it changes from normal brightness to very very dim, but not off. It goes completely off when the device goes into standby.
I use Mortplayer for listening to music, which has a feature that turns the screen off, not just the back-light, which saves a lot of battery power.

Not neccessarily... It has a setting on the Battery option where you can select the amount of time after which the back light goes off both on battery power and external power.
Anyway mine stays on even when its not connected to the PC ie, external power.
It just goes dim after the specified amount of time and stays like that untill the device goes off.
Thanks.

When you say 'goes off' do you mean 'enters standby'? When not connected my p3600 dims the backlight after 30 seconds. Two minutes later it enters standby (that's the time I set it up from settings). However it only enters standby if I don't listen to music.

Hi,
I noticed the same proble, I never the used the original Rom coming with the Trinity cos I bought it last Sat and I installed the DOPOD test rom with GPS support straight away.
With my TYTN when I'm on a call after a while (a minute) the screen togles, however with the TRINITY the screen stays on (brightness goes away) but still there (no togle).
Can somebody with a non-gps dopod rom confirm that they do not suffer this behaviour?
thanks,
Elsral

My Trinity is still original (Dutch). When in the backlight settings, I slide the indicator all the way to the left, the backlight still is on (very low, but it is still on).
A colleague of mine has a Hermes; when he does the same thing, his backlight is off completely.
Also, before the P3600, I owned an Ipaq 5550 which also was able to switch backlight off completely.
Hope this is corrected in a future ROM update...

German Trinity Original ROM here. The device switches the screen completely off after the amount of time I have selected. It is the same behaviour that I know from my other pocket computers and it seems completely ok. Something wrong with the Dopod ROM?

Power management problems/disillusions

I have my P3600 since Saturday and I updated it with the latest ROM which included the GPS.
Now I’m having problems with the power settings and functionality. I search all the threads for solutions but no similar problems are described so I post a new thread.
Problem 1:
The power settings are: backlight off after 30 sec. power off after 1 min. (on battery power). After 30 sec. the backlight dims to the lowest setting but the device does not switch off after 1 min (or any time for that matter). This is a huge drain on the battery! I can switch off the device with the power button but once it turns on again (e.g. while receiving an SMS or email) it stays on with the dimmed backlight.
Problem 2:
Using a Bluetooth headset and the media player the player pauses when switched of with the power button. This means just listening to music for around an hour and the battery is completely flat. My previous device was a S200 and that worked fine (could be switched off with the power button).
My guess is that both problems may have simple solutions so I’m asking you all to help me with this.
Thanks in advance,
Stefan

Well for problem 2 you haven't searched enough! Anyway you should not use the power button; go to the Windows Media player settings and map the "Toggle screen" function to a hardware button. Then toggle the screen off when you play music.
Regarding your other problem: what software have you installed? Have you got this problem on a freshly upgraded phone?

The solution you propose for problem 2 probably works for other devices but not for the Trinity. You can only assign buttons up, down, left, right and enter and they are needed within the player for obvious functions.
Problem 1 after fresh ROM update but right after that I installed TomTom 6.
I might try a new ROM update and check but rather as last resort...

It works for the Trinity too. You can also assign other functions to buttons if you keep them pressed. Toggle screen is assigned to "Hold Down" in my case. So if I press down once I decrease the volume, if I keep pressed I toggle the screen.

As to your first problem; i'm having the same problem too...
To narrow it down a bit; my device turns off (to standby) just like it should when i just briefly check the time or something and then put it away with the todayscreen on (so with no aplications running except some today-plugins ofcourse). However; it DOESN'T go back to sleep when the system has given any sort of notification, like a missed call or a received text-message or reminder for a calendar-item.
So my best guess is that it has something to do with the databases notification que (where WM2003/CE 4 had the problem of overflowing this notification que).
It's really anonying the hell out of me too, cause it really drains the battery fast if you don't discover it soon enough...
As for problem 2; map the screen-toggle to pressing the silver 'enter'button.....that workd great for me. By the way; i'm tinking about getting the new wired media remote control HTC is releasing shortly (check this link). I wonder if these buttons will be mappable.....
Edit: just as i posted this, i received a text message and this time it nicely turned back to standby (ie turned of) state when i didn't check it right away. I did however soft-reset last night before going to sleep. So i really do think it must be in the notification que somewhere, as PocketPlus will still clear that everytime i soft reset. Anyone having the same problem exactly as described ?

Well I found my phone again on after I received an SMS and this made me decide to completely reinstall the original ROM (including the GPS).
Step by step I installed all the applications (and tested the device in between: I started some programs and got some notification).
So far the result is that it all works fine now.
The difference might be the different ROM (from smartmobility.nl in stead of europe.htc.com although the version is exactly the same).
For problem 2: I unmapped the button 1 (was speed dial and moved that one to press&hold). In media player I mapped the button to ‘toggle screen’. I still like the S200 for this better because it only kept the media player & Bluetooth alive so that’s the best for preserving the battery…

Hmmmm....i do the screen-toggle everytime i use it as a musicplayer, and i get considerable good batterylife....
However, i'm not using the BT headset anymore cause the volume was too dim...i'm using the 3,5mm adapterplug now. But batterylife with bluetooth was about the same when i used it.

After all the work yesterday, this morning the problem with not going to standby occured again!
But now I know more. It happened only after I added some sites to my RSS feedreader.
I use pRSSreader from David Andrs (http://pda.jasnapaka.com/prssr/)
Using the 'update settings' with 'automatically connect' the program tries to create a notification on the today screen if new messages arive.
This notification process is the problem. If I switch it of and soft-reset, the device works fine again.
I will mention this problem to David Andrs...
I hope this will help you as well.

audio stops playing when display is off

I'm using elfin running WM 6.1. The prob is that when i play a song in the audio manager and try to switch of the phone's display, the song stops playing. I used to do this in 6.0 and unfortunately this is not working in 6.1!(just to save power) Any thoughts on this?

bumpp... in no one's mind..?!!

Well... when the display goes off, the phone goes into a kind of "standby" mode, all in a effort to conserve battery power... even the wireless is turned off =)

the reason why i posted this doubt is that, when i was using 6.0, the audio used to play even when the backlight is off.. now this is not happening in 6.1..

Yes, audio usually stops playing when the screen is off, its normal.
Some programs like coreplayer allow you to go the menu and press on the key that says, Turn off backlight, which will allow the music to continue to play.
If you use the Onyx ROMS, press and hold the power button and click on backlight.
