Email from a customer:

I bought this time machine, and I love it! I have one question though. I have the HDMI cable plugged into 
an HDMI splitter, shared with a Retro Nintendo system and a TV. For some reason, when any of the other 
two devices is turned on, the time machine turns on. Turn it off by the button, and it turns itself back on, 
I think the next time another device connected to the HDMI switch turns on.

Is there a way to change this behavior? Leaving the time machine plugged into everything, 
but it only turning on when I press the power button?

I have reproduced the customer issue. In fact, all I did was turn off the Pi, then plugging in the HDMI connector causes it to power up.

Could this be related to the LED circuit? -- I don't think so because my desktop dev Pi doesn't have an LED. But maybe I configured something to allow the LED circuit to work.

Based on some playing around, I think I should modify /boot/config.txt to say

# uncomment if you get no picture on HDMI for a default "safe" mode
hdmi_safe=1

This ensures that the HDMI will work, even if it's off when the Pi is plugged in.
