network cables query

I have a BT voyager modem router with 4 network inputs which have
lights to indicate connected hardware, my query is the cables.

I have 2 pc's which even when turned off (they have wake on lan
disabled) light up on the voyager, yet other hardware connected only
light up the connection when powered up ?

Is this the PC's or the cables ?

I have tried the 2 offending cables in different sockets on the
voyager to check it wasnt socket 1 & 2 on the voyager (it wasn't).
Haven't yet tried plugging different hardware into the offending
cables(moving hardware around ( )

Could this actually be the cables, if so why ?

Just realised I could unplug the RJ45 from this pc to see if the cable
alone lights up the voyager, have to do that after sending this, but
if it could be the cables any info would be much appreciated.

It's the PC's. Some turn the power on and off to the network ports
when it's powered on and off, some don't. Also depends on where the
LAN ports are, i.e. PCI cards or on board.

Yes, the LAN posrts are often left powered so PCs can be woken up via
the LAN to do remote updates etc. Obviously if the mains is switched off
at the socket (which you should really do - like not leaving things on
standby - to save the earth!) the LAN lights should go off.

I disagree when it comes to PC's.

Well, if someone wants to cite sources then it would be handy but
AFAIWA unplugging PC's from the wall all the time didn't do it much
good. Maybe not so much with new PC's, dunno, I'm against it anyway.

If it's powered down already then it's not going to do anything apart
from maybe extend the life of the PSU and lower your electricity bills
slightly.

The PCs. With the PC off power is still reaching the network cards on
your PC. This is quite normal.

Probably true if you have a network connection via the mother board but
probably not if you have a PCI card or similar.

ATX mobos can usually do WOL with compatible PCI NICs - older ones may
need that little three-pin cable between the NIC and the mobo, newer
ones don't because the required connections were added to the PCI spec.
