Send a Signal

A phrase that I hear from customers a lot is "send a signal". I'm not really sure what it means, but customers say it a lot.

My best guess is that it's something Comcast techs say to simplify the explanation of various ways they can check modem diagnostics, or occasionally restart a modem remotely. They say they're "sending a signal" and the customer figures that's something that we can do to fix any problem, whether it's related to the modem or not.

As in, "can't you send a signal to my computer to fix my printer?"

Or, in this case... "My computer won't turn on. When I press the power button nothing happens, and the screen stays dark. You can send a signal to fix that, right?"
