Usually, indicator LEDs on consumer devices are controlled in firmware, or even hardware, and would not be available to the operating system. You would probably have to reprogram your laptop's boot ROM. Unless you're extremely thorough, once you did this you might never be able to trust any of your indicator lights again. Personally, I'd sooner drill a hole in my case and add additional LEDs that are controlled through a USB port. Even easier would be to build a USB dongle that fits inside a port.
