X7500 Backlight Slider not functional

Hello xda world. Like the forums... I'm new to PPC, but I've previously developed Palm apps.
I've had an x7500 for a week or so. Lots of messing around trying to get a configuration I like, and somehow I've managed to break it (maybe).
The backlight works fine - when there is no external power.
However, when external power is applied, the backlight goes to its lowest mode and will not honour the slider settings in the Backlight app.
This is really, really annoying. Any suggestions?
Is it a PPC or an HTC thing?
Thanks & regards

i remember i had similar problem before, do you have Phone Alarm install?

Thanks for your help, but... nope no phone alarm.
(In the phone app right? I don't see any options for a phone alarm.)

hi Devany
not sure if you managed to find a resolution but i too had a similar problem.
i think mine was caused by phonemanager (which i have since uninstalled)
i found that when on battery power the slider in backlight settings did absolutely nothing. the only time the backlight would become brighter was when the alarm was going off.
searching throught the registry i found the solution.
navigate to HKEY_CURRENT_USER\controlpanel\backlight
change the onoffbat key to 1 (mine was set to 0)
once done press the power key down for ages to reboot.
my slider now works fine.
hope this helps

Perfect keylock

Hi,
I've been trying to figure out how to implement the perfect keylock. Currently, I'm not able to find a keylock program/MortScript that does the following:
1. Lock the keypad if phone goes into standby
2. Auto-unlock the keypad if the power button is pressed.
This way, when I power on my phone, it's not locked. But if it's auto-powered on (ie reminder, etc.) then it will be locked.

Hi, I find it interesting that, you can upload scripts please
Greetings and Thanks
Sorry for the English

have you tried S2U2? (Slide to unlock - keylock similar to iPhone's)
Think it does 1) not 2), but I'm not too sure...
it looks cool though

Our device does both points as standard. Problem that it powers itself on and automatically unlocks when for example a call or any notification pops up on the screen.

I agree with hachuah's idea about automatic locking, so I'm looking for application that could:
1. Lock the screen if standby
2. On standby mode. If I tap some part of the screen (some part of screen only to save some batt power), then it would show option to unlock.
3. If I tap, but do nothing or do not unlock, it would goes to standby again.
With above I do not have to push the power button, buttons are easy to be come wear and stay down.
I'm even gladly to pay for someone who's willing to create that kind of application. Or is it already available?

I seriously doubt if that could be archieved by software alone. The touch screen is essentially connected to the LCD power. If the panel is off, the touch screen is off.
Furthermore, it's a all-or-none operation - you just can't have "part" of it on, and ther other part off. I am pretty certain no manufacturer would ever produce such an implementation, even if they could.

I know that Symbian phone able to do that.
So, basically I could set the timer for the screen to go off. And when the screen off and tap on the screen, it will ask if I want to unlock the screen or not. If not, it will go off again.
So, from what you said, it is impossible to make the screen off but the touch on? It is a hardware issue then. What a sad. Only recently I moved from Symbian to WM, if only WM doesn't rely on button too much.
Or maybe it is possible by set the brightness to very minimal, so doesn't display anything, but the touch is still working?
So, it's an application that would turn the brightness off and lock after some defined time. And would turn the brightness on again when the touchscreen is tapped to ask if user want to unlock.
Is it possible?

Perhaps I should clarify what I said - what I meant by "all or none" operation is that the *touch screen* won't be able to get switched on partially - to save power as you have hoped.
In fact, the touch screen is technically separated from the LCD panel itself, and the backlite too - but it's either a MS or HTC decision that they are stuck together, i.e. you just can't have the LCD off, with the touch screen stays on.
In fact, recent HTC devices WM5 or above have elmininated the function to actually turn off the backlight while the LCD panel is on.
So what we can do is very much limited to use a button based keylock, instead of a touch screen based.
As for your suggestion to display "black" on screen while keeping minimal backlight - it's note quite practical in HTC devices. First the backlight must be on as I said earlier for it to display even "black" such that the touch screen is responsive. It follows that your battery will be drained extremely quickly.

Even with very small power to LCD for the touch could work still takes too much power? Aww.. so it is not possible to do what I want.
Well, I guess I need to get used to with using button, or maybe next time I will try to use bluetooth device to wake the screen.
Thank you for the information, very educating and useful.

try either of these, i think they might both do what you want

backlight dimmer

Hi all,
I am looking for a program that turns of backlight while speaking on the phone, by dimming it once you answer the call. This would save lot of battery for those speaking on the phone alot. I know that I can change the turn off timer from settings menu, but I don't wan to do that as it applies to all functions.
Just need an additional software that can manage the backlight while speaking on the phone.
Thnx

Touch-screen response with backlight off

Hi all!
as you might have noticed, the device does not respond to screen tap/button push while backlight is turned off, the first action turns the backlight on and you have to repeat it to make the device do what you want...
Is there any way to let it respond to each action while backlight ist turned off?
Many thanks and sorry for my english

So far there is no solution..i posted this a while ago too.
I just turned backlight dimming of...it was to annoying.

Honestly I'm deeply grateful for this option!!!
I can always turn on/off the light with powerbutton.
Often I want to put the back light on WITHOUT any change on the screen (like reading ebook when screen-press makes page change). So I just love it how it is.

The problem is that it isnt an option
Actually i do not have a problem with it, i ask here fore smb who has a program, where keeping backlight on doesnt work properly so this option make some problems,
i would love this on fs loox 560, but since xperia cant turn the backlight completely off and i can see everything without turning backlight on and i just dont need it anymore
Thank you two for your replies

Actually you can touch your camera button first to bring the backlight back/prevent backlight fade, then click what you want to do

Hm... It doen't bother me at all. I even like it.

Could be a numpty questions...power on by pressing screen?

I have recently taken delivery of an Otterbox for use on my bike (GPSComputerCycle and music) but to save power I would like to be able to turn the screen off during the ride (xpshutdown allows me to do this) and then press the screen if I want to turn the HD back on again.
I use S2U2 if this makes an difference.
Is there a setting somewhere which allows me to press the screen to power the THD back on again (even if it goes to a lock-screen)?
I had a quick look through the settings (Screen/Power/Lock) but couldn't find anything.
Anyone help?
Thanks

Not possible AFAIK.
When the screen powers down, that applies to the touch-sensitive mechanism as well as the display element.
It would probably require something deeper than even a registry hack, the drivers would need re-writing or something.

Its not possible for the simple reason that the buttons below the screen are part and parcel of the touch screen, so if the screen is off, they won't work.
There appears to be no power to these lower buttons while in standby, so no software could work either?
However there is other ways of doing this:
1. Use s2u2 unlock on stylus out, so when you pull out the stylus, the HD comes on and unlocks. It's simple.
2. MobileMagic to toggle the screen on/off when device is turned face down. That way when you turn it face down, screen goes off and buttons are locked. To turn it back on, turn devicedevice face down again. You will need need to go to Start-Settings-System-Power-Advanced and untick the option, "Turn off device if not used for", because if the device gets turned off (instead of just screen off) it won't respond.
Hope this helps

Unfortunately the HD will be inside an Otterbox mounted on the handlebars of my bike, so removing the stylus would not be an option and neither would using the G-Sensor.
Sounds like I will have to have it powered on all the time. I know that GPSCycleComputer dims the display while it is active, so this might be a part solution.
Thanks for all the answers though. I was being a numpty after all!

Alternative solution:
Attach a dynamo to the wheels of your bicycle and charge your HD on the go
I wouldn't be able to even begin telling you how to do this though!
