How to avoid the power button dimming the backlight?

[Robert]

As you may know, press and hold the power button will dim the backlight on
most pocket PCs. Once dimmed, the only way to turn the backlight on is to
press and hold the power button again. This causes some problems for some
ordinary users: they accidentally press and hold the power button and turn
the backlight off but do not know how to turn it back on.

So, I want to disable this feature on the iPaq h22xx series , that is, make
the power button turn on/off the device only. Some Pocket PCs like Dell X51
has this as a option under Settings, which make me believe it is in the
registry.

Has anyone successfully done this or know where the registry key is for iPaq
h2000?

Thanks!

You're assuming it's a registry key. It could be a nonconfigurable OS
feature, or even done below it in a CPLD or similar. Regardless, there's no
standard backlight control API, and I've never heard of anyone even
attempting to change this specific behavior, let alone succeeding to do it.
Sounds more like a training issue anyway.
