Solving the backlight issue

[laita56]

Hi,

Many of you may encounter some problems regarding backlight after:
- modifying default settings for backlight
- installing TOMTOM or TCMP

To solve this, just modify the registry key (using regedit if you unsigned your phone, or using http://www.pocketpcfreewares.com/fr/index.php?soft=1399)

HKCU / Control Panel / Power => values => put 30 for 30 seconds, 60 for 1 mn, ...

when i go there i see only one string and it says (value not set)
what value i need to change ? can i get more specific info
please

[Nicoolai]

I'm also alittle curious to what i actually need to change. There is only one value there, and it is set to 4, other then that there's just the add-key.

on mine it was set to a really long number like 96237342 or something after i installed core player. i just removed it and set it to 60 and it worked.

Thanks a heap - works also on CorePlayer, even though I shouldn't have to mess with the registry because of an app that cost $25.

first of all, merci beaucoup laita56

as laita56 explained it very well already (thanx mate), i will try to add some more infos for the curious of us.

if followed the steps that laita56 did (see first post (http://forum.xda-developers.com/showpost.php?p=1230265&postcount=1)), you should already have "Mobile Registry Editor - v1.1" on your
computer. Please start that application.

You should see this:

know click on the "+"-signs of

+HKEY_CURRENT_USER ,
+ControlPanel ,
+Power ,

click on the folder Power (the one that you just expanded)

in the right half of "Mobile Registry Editor"-window, make a right click and select "New > String Value"

till here the whole procedure looks like this:

http://kel.gmxhome.de/xda/bli/pic_002_006.png

in the "New String"-window that has opened, you have know to input the disered values. First we name it, in "Value Name" we type "Display". Secondly we will give the Timeout value, in "Value Data" we (as example) "30" for 30 seconds.

this looks like this:

finally click on "Ok" and we're done!

Softreset your phone to activate the new values.

Happy reg editing!

I will continue on this thread as it best matches the problem that many are experiencing. While the solution the "problem" that many applications are creating is outlined below, many will "mysteriously" see the problem reappear again after some time.

Well, the reason is simple: In their infite wisdom, HTC have chosen to replace the default display timeout handling (stored in HKCU\ControlPanel\Power value for Display) that seems MS Standard by a private setting - that allows to have different display timeouts if running on battery or on AC.

Unfortunately calling the settings panel for the power-settings will (by accessing the HTC tooling for manipulating these values) enforce the HTC-handling by deleting the key Display at HKCU\ControlPanel\Power and thus bring back the old problem again!
So what?

Well there is a key "OnlyDisplayTimeout" which has to be created in HKLM\Software\HTC\PowerManagement and set to "1" - this will change the HTC panel behavior to the MS intended and it will work on that single value from then on only.

should i greate a new string or how shall i change the value. I have no value right now.

Creat a new value...name:Display value:what u like...15 30 60 etc.

it'll work well!

[tobbbie]

You need to create a key "Display" (type DWORD) and assign the value for the timeout. You must create the other key "OnlyDisplayTimeout" (type DWORD) and assign the alvue "1" as well to keep the settings of "Display" alive even after calling the Settings panel Power options.

You can even ONLY create the key "OnlyDisplayTimeout" value = 1 as from then on the Setting-Power will exactly work on the Display key - even create it if it was not there.
