Hi,

the following problem appears to me as I played around with wake on lan: Having
the mashine in suspend-to-ram-mode, I can wake it up from another mashine
without trouble. But when the mashine-state is powered-off, the there is no
chance to wake it.
Additional info is, that on my switch the according leds for the mashine are
lighting in suspend-mode but not in powered-off-mode.
Any help would be appreciated.

Thanks, digo.

Does "Power On By PCI Devices" [Enabled] help ? Maybe the 3C940 is wired
to the same power source as the rest of the PCI bus.

No, it was enabled. And to go mre in detail: When suspending or shuting-down the
machine from WinXP it's no problem to wake it via wake-on-lan, but shutted down
from Linux or deplugged from energy and then replugged, then there is no way to
wake the system up. In these states where the system is not wakeable the
according lights on my switch are off. In the suspend- or shutted-down-states
from WinXP these lights are on. What's the deal? How to fix it to wake up from
every state?
Thanks in advance, Dirk.

There is an option in the BIOS "Restore on AC Power Loss" and setting
it to [Last State] may help with the deplugged and replugged
problem. When you replug the machine, you will hear the power supply
come on for a few seconds, during which the BIOS will reconfigure
the motherboard for the last ACPI state set on the machine. Then
the BIOS will suspend the machine again. Wake On LAN should then
work. An undesirable side effect is that, if you try to shut the
machine down completely, it may just restart on you (you should
test this).

As for Linux, if it has a full ACPI or equivalent implementation,
then that should give you the waking functions. If parts of ACPI
are not implemented, then you'll have problems.

HTH,
Paul
