Answer

Backlight settings are not retained after the device is cold booted or loses power for an extended period of time.
The setting is stored in RAM and is lost when the device is cold booted or power is lost.

Create a registry file for the setting so that it is cold boot persistent.
  1. Open Notepad on the PC.
  2. Cut and past the following key:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\BkltDrvr]
"Contrast"=dword:00000008    ; 8=super bright
  1. Save the file as backlight.reg (the name before the .reg can be changed to anything).
  2. Using ActiveSync, place the file in the Application folder of the device.
  3. Cold boot the device.
