Thanks for the information.
I've checked the kern.log and other logs in /var/log but nothing relevant showed up (to be exact no log-entries at all when the LEDs light up).
Like you suggested I've also tested it with my notebook and it shows the same behavior with a fully upgraded Ubuntu 16.04.2 LTS.
