General

The intensity tag will only have an observable effect if the keyboard backlight is turned on, setting the intensity by its self is insufficient to illuminate the backlight.

Device Limits

The levels of supported keylight intensity is device dependant. When the Keylight module is first loaded it writes the supported levels to the log file as INFORMATION so you can determine the maximum setting from the log file.

Supported Platforms	Windows CE, Windows Mobile
Persistence	This tag is persistent.
Min. Requirements	This tag requires appropriate hardware and drivers to run, i.e. a device with a keyboard backlight.
