Always remember to do a proper soft-reset when applying settings like this. (Proper = turn off with button not ripping out battery, push stylus in reset hole, etc). I haven't tested on the iPAQ - the tricky thing about the whole backlight feature is that HTC/HP/Samsung all do different things in their implementations...

Note that this key is also tied to a phantom resetting of the time before the backlight turns off, too. If the value is set to = 1, which is the default on the iPAQ 900c, then if you change the backlight to not go off for 2 minutes, when you cycle power, your backlight delay will be reset to the factory default, in the case of the iPAQ, 10 seconds. Nice to know at least what this key is supposed to be for. Thanks! Great info, but where did you go to find out about the registry key’s purpose?
