[Bug] Single LED blinks repeatedly when I put all my computers to sleep (idle)

Describe the Bug

I have a Macbook and a Thinkpad connected to a ConnectPro KVM. One is for work, one is for play. When I wrap up for the day I suspend the Thinkpad and "sleep" the Macbook (actually reverse order usually). Then the blue LED starts to blink in regular intervals. As this is pretty annoying, I cover the LED portion of the keyboard with a coaster.

This has not happened before I got the Macbook.
