Need some insight. Modem was working fine...maybe a bit sluggish, but that could have been the provider. Then it stopped working. In fact, the modem will not turn on now. I'm about to contact service to get a warranty help, but I figured I would try the community forum. Any advice would be helpful.

you can try a different power supply. it should be a pretty standard power supply so if you check some of your other devices, you can try one and see if it is that. just make sure its got the same voltage and polarity. it can have more amperage.

If its plugged in and not a single light is on, something failed.
there's things you can try but I'd go through your warranty option first so you don't void the warranty.

  Yes, it was plugged in with no lights showing anywhere. Looks like the warranty only lasted 1 yr from purchase. Any other suggestions?
  I'm suspecting it's completely fried and will need to get a new cable modem
