Keyboard turns on in sleep mode

[waloshin]

My Logitech K710+ as well as my BlackWidow turns on randomly during sleep mode. What causes this? It will illuminate for awhile then turn off. Late 2012 mac mini.

this happens to me with my 2012 blackwidow ultimate and 2014 mini with el capitan. like an hour after it goes to sleep the LEDs will lightup but then turn off like a few mins later.

No idea whats causing it.

This is normal. Macs turn on briefly from time to time for various services.
