 Windows Mobile Tweaks
Enable original backlight and contrast applets
Many OEM replace the Backlight and/or Contrast settings applet by their own versions :
Compaq iPaq 3650 :
OEM Backlight applet, same as original but with a Brightness tab for iPaq special purposes. Removed the Contrast applet because contrast settings are not supported on the iPaq.
Casio EM-500 :
OEM Brightness applet that replace both the original Backlight and Contrast. Added the ability to set different brightness values for battery and external power operations.
Removed "Turn on backlight when a button is pressed or the screen is tapped" settings because it is not supported, replaced by the Auto Dim settings.
Included the contrast in the same applet, the system one does work, but their device act at the oposite of what it should (Dark is Light and Light is Dark).
HP Jornada 548 :
OEM Backlight applet, removed the External Power tab the "Turn on backlight when a button is pressed or the screen is tapped" setting for Battery Power because these settings are not supported.
Now, here is how to restore the Microsoft original applets on any Pocket PC, note that most settings OEM have been hiding with their own applet does not work anyway, the OEM applet(s) will still be available in the Settings.
For the Backlight applet, browse to
HKEY_LOCAL_MACHINE\ControlPanel\Backlight\
Rename the "Redirect" value to "Redirect disabled", you could just delete it, but renaming it makes it easy to go back to the OEM setting.
For the Contrast applet, do the same with
HKEY_LOCAL_MACHINE\ControlPanel\Contrast\ |
