turn off backlight tweak wanted

is there a way to change the choices for the default amount of time before the backlight turns off?like having a 30 mins choice in the "on battery power" setting.maybe by tweaking the registry?anyone?

Backlight woes

Hi,
I'm trying find out what reg key is used for setting the backlight off level.
At the moment, after the 30 second timeout, the backlight is set to dim (1) - what I want is to make it completely shut off, without turning off the display.
Before I get told to search the forums, there are a few threads and certainly one or two have already asked, but none have a solution.
I've tried setting various levels such as under HKCU\control panel\backlight - i was thinking that onoff or extonoff may do what i want, but to no avail after a soft reset
Any ideas?

Dunno about what reg key this effects, but it sounds like you're looking for the timeout settings as opposed to the backlight settings.
This can be found in the control panel, under power -> advanced, and here you can set how long it takes to hibernate the device.
Not sure if you still need the reg. settings, but it might help to know that backlight entries are probably the wrong place to be poking!

What's the model of your device?
Some manufacturers like to go proprietary, eg. ASUS, in which case, you will need IDA and hack your way through.

HTC 3300 with either WM5 or 6 - it's not timeout settings or whatever, even if i set the backlight to as low as possible within the OS, it is always slightly on.
It appears the OS sets the BKL value from 1 to 4, 1 being dim, 4 being max brightness.
I can get it to turn off by setting the value to 0 manually in the registry and doing a soft reset, but thats not exactly ideal - I just want the device to stay active but without the backlight as thats what uses up most of the power.

my 2 devices, O2 mini and asus P535 allows the display to stay active and the backlight off. this can be achieved using the control panel applets which implies self-developed software can do the same.
so the question is, can your device achieve that state using built-in applets?
if it can't, then it's really a gamble for you to spend time finding a way.
i'm assuming that when you set the registry to 1, your backlight turns on slightly? most devices can't be viewed properly without the backlight, so in my opinion, there's little point in leaving it on without the backlight.
why do you need the display active? perhaps there is a better alternative to reach your goals, eg. LEDs

Screen dims on power

My touch HD has just started an annoying habit - when it is on external power, the screen dims to about half-brightness in about 5 seconds. This is extremely annoying in the car cradle as it is very hard to read.
I cant find anywhere in settings or Advanced Config to change this.
Is there somewhere i can change this? a reg key?
cheers

settings > system > Power > backlight > uncheck auto adjust andf settings for external power should show up.

thx bigf00t - i tried that before, but it only changes the actual brightness of the screen while it is on power and in use. After I adjust that it then dims again after 5 seconds no matter what the setting.

You may try settings -> systems -> Power -> Advance, you should able to find what you need there.

ok - that was definitely it.
"Turn off backlight if device not used for" was set to 1 minute. I changed it to 2mins then back to 1 minute and it actually stayed bright for 1 minute instead of 5 seconds!
Nice to know that "turn off backlight" actually means "dim backlight"

Backlight goes off in 5secs when battery at 50%..

Searched and searched but couldn't find an answer.
As the title says.... I can still see the display is on and its responding to my inputs but no backlight at all.
Have tried adjusting all backlight options disabling and enabling them to no avail.
always start to happen at 50% power then every 5 or so secs it turns off so i need to press the power button twice to turn it on again but have it turn itself off if i left it to idle for more than 5 secs.
Settings currently for on battery at dim backlight 30secs, power off 1min. on AC dim at 1min, power off at 10mins
Comforting thing is when playing videos with coreplayer, backlight remains on.
Anybody any ideas?
started when i flashed back to official 1.66 after mtty and now am on merlion 2.4 also after mtty. could it be that i always flash at the 50% to 60% power mark??
Currently draining my batt to see if it is the batt sensor's problem....

Backlight on when phone is off

I've done the usual search and can't find anyone reporting this . . .
If I turn mt AT&T Pure off with the power button (not complete power down, just normal on/off) I notice a faint glow from the screen like it's still trying to show the backlight.
If I power up and then power down a second time, there is no glow.
This phone is running stock AT&T ROM, and it happens on battery power - so I'm concerned that it's draining the battery unnecessarily.
Battery settings -- "Auto adjust backlight" NOT checked
power save sliders around 30%.
Advanced tab -- "On battery power" - both boxes checked, 30 sec backlight off, 3 minutes turn off. "On external power" - neither box is checked
Any ideas?
Thanks

Try installing this cab, changes registry to auto lock with power button.
If it doesn't work, you may consider a lock screen such as smart lock.

Thanks for the post, but I don't understand what it does -- could you explain how the phone should behave after installing the CAB?
Thanks

Using this reg edit makes the device go into standby once you press the power button, no backlight staying on etc.
Includes the following reg edits.
