WOL in the BIOS causes spontaneous power ups after shutdown

Post by graysky » Sat Nov 30, 2013 11:27 am

In order to support WOL, my Asus H87I-Plus requires an option set in the BIOS (Onboard>APM>Power on by PCIE). When I have this enabled, I can indeed start the machine using the wol magic packet, but there is an undesired side-effect: about 25 % of the time I shutdown the machine, it stays shut off for about 5 sec and then turns back on all by itself. If I disable the option in the BIOS, this does not happen... but I am unable to use wol.

Anyone run into this issue before? Motherboard BIOS issue?

With the network cable disconnected does the same thing happen? If you can show that then it is definitely some sort of BIOS/mobo issue.

I will disconnect it and see. Is your thought that some other machine on the LAN is sending the magic packet to wake up or just that some kind of voltage is tripping?

More likely some sort of voltage thing. I have seen this before many years ago with a Supermicro workstation board, the only solution was disabling WOL.

Isn't there any packet flying around your network and waking up your PC?

No, never been a problem until I purchased this MB.

Update - Latest BIOS 1005 does not fix this problem and 14 emails between myself and the people at Asus who barely speak English have not been fruitful.

I've been experiencing the same issue with this mobo.

The fix for me was to go into the Properties of the Network Adapter in Device Manager and change the settings on the Power Management tab.

"Allow this device to wake the computer" should be ticked by default. I also needed to tick the box below this option which requires a "magic packet" to wake the PC.

This seems to have fixed the issue for me.

Booting into windows 7 and then shutting down from there does not exhibit this behavior. It seems to be something unique to Linux...

An update: this is a BIOS bug but there is a work-around. I have been testing several systems (Z77 and H97-based) after I disabled all references to 'xHCI' as it pertains to USB settings[1]. I also enabled wake on keyboard[2]. And finally, I disabled EuP 2013 which affects wattage in power off mode. For over 2 months now, I haven't observed an unintentional wake-up with 'wake on PCIe' enabled in the BIOS.
