My Motorola HD box sounds like it's on whether the power is turned on or off. Is this normal?
Yes, these boxes don't truly turn off, the blue light on the front panel turns off but the box is still connected to the server to receive updates and to start recordings.
What model of Motorola HD box do you have? Are you referring to a noise that may be coming from a fan inside the unit?
It's a DCX3510-M. And yes, it sounds like a fan. Should that be running constantly?
