Modem Activity - Sleep vs Shut Down

When my PC sleeps the light on my modem that signifies being online stops blinking and goes dark, but it continues to blink when I shut down. This seems curious. Anyone understand why this is the case?

Thanks.

Hello. All modems react different, might just be the way yours functions. For example , my modem has the Power light.. Data . send and recieve , Cable, Pc. My power and cable are always lit.. while the others blink as there function dictates.. The ones i really get concerned about are the Cable and Power.. if they go out.. I am off line for sure.

Thanks for the reply. I spoke to an online tech representative who had no clue why there's a difference although she did say that the modem remains online when the computer is shut down so that it can receive updates if necessary.

Yeah, as mine flashes for the send/receive even if I am offline or computer is sleep . Makes sense to me .
