In general it means nothing. A power supply is still active even when the PC is turned off as long as the PSU is not turned off. There is some standby power for activating the PC, wake on lan, in some cases you can charge your phone via USB with the PC off. How much you can do is motherboard dependent.Trying to do a bit of troubleshooting and was offered this advice. The keyboard keys will not light up with the cpu in the mobo
Thanks
