I have a MiniITX-based NAS (motherboard - POV ION-MB330) in my network that won't shutdown properly when Wake by PME (Wake on LAN) is enabled in the BIOS. When Wake by PME is enabled and shutdown command is sent to the machine, or the PW button is pressed, it just reboots, it does not stop operating. If wake on LAN is disabled in BIOS, the machine shutdowns normally. My question is - How can I keep the WOL ENABLED and still be able to shut down the machine properly?

There are four disks attached to the system - 2 x 2TB WD green, 2 x 200GB Maxtor. There is also one USB hdd (1tb Samsung). It doesn't matter if it's plugged or not, the result is the same. The NAS runs Debian Linux.

The reply to the email I wrote to the manufacturer's technical support

This mainboard is EOL, and there are for some years no bios updates more developed . I am sorry, but unable to help you with this matter

With kind Regards

Obviously they don't know what they are talking about.

Does someone have any ideas on how I can get rid of this nasty problem?

There are a couple ways Wake-On-LAn works. One is to wake up on ANY packet, and the other is to only wake up on receiving a Magic Packet.

You can test this by leaving WOL enabled, but pull out the network cable before shutting down. If it stays off, it's probably set to wake on any packet.

This will be controlled by the OS.

For example, in Windows you would check the properties of the network card, and under the "Power Management" tab, there will be a couple check boxes:

"Allow this device to wake the computer" - Checkmark this if you want WOL to work at all.
and under that
"Only allow a magic packet to wake the computer" - If checked, this will do as it says and only wake on a WOL magic packet.

These are quoted from Windows 8; the wording is slightly different for previous versions of Windows.
