I will have to wait for someone to test the extra bits, then, because I can't provide a LED interface where ON is not working well. BTW, given the above clues that the LED has brightness control, testing these extra bits on the thinkvantage LED is probably safe. I *cannot* be really sure it IS safe, but the hints are there that these bits are required to use the thinkvantage LED, and the ACPI method to control it certainly makes that clear. It just doesn't tell me what the bits do. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
