Problem

Systems based on the Q87 CS-B motherboard (BOAMOT-467) may not give reliable wake on LAN functionality. Wake functionality may only work when the system has been powered down through the operating system (with the AC mains not disconnected from the power supply) or it may not work at all. This is evident on machines shipped up to and including 27/1/2014.

More Details

Wake on LAN functionality is enabled by default in the shipping BIOS of systems supplied by Stone. Wake on LAN should be possible from all of these states:

  • After proper shutdown of operating system.
  • After powering off the system using the power button.
  • After turning the system off, then disconnecting and then reconnecting the AC mains.

With the BIOS shipped up to 27/1/2014, this functionality does not work reliably.

Cause

The cause is a BIOS glitch which has now been corrected. The problem is caused by problems with the factory BIOS configuration tool rather than with a specific BIOS version.

Resolutions

Work Around 1

Disable and then re-enable Wake on LAN functionality in the BIOS.

To disable:

  • Go into the BIOS by tapping the F2 key after turning the system on
  • Go into Advanced mode by pressing F7 (then accept the confirmation prompt)
  • Use the arrow keys to go to the Advanced Menu (two presses of the right arrow)
  • Go down to APM
  • Set "Power On By PCI-E/PCI" to Disabled
  • Press F10 to save and exit the BIOS

To enable:

  • Go into the BIOS by tapping the F2 key after turning the system on
  • Go into Advanced mode by pressing F7 (then accept the confirmation prompt)
  • Use the arrow keys to go to the Advanced Menu (two presses of the right arrow)
  • Go down to APM
  • Set "Power On By PCI-E/PCI" to Enabled
  • Press F10 to save and exit the BIOS

Fix

Flash an Updated BIOS

This problem can also be fixed by updating the BIOS to the Stone 1201s BIOS or later, or a later generic Asus BIOS if necessary.

To flash the BIOS:

  • Download the BIOS file and put it onto a blank FAT32 formatted USB pen drive
  • Insert the pen drive into the system
  • Turn the system on and tap the F2 key to go into the BIOS
  • Go into Advanced mode by pressing F7 (then accept the confirmation prompt)
  • Use the right hand arrow key to go across to the tool menu (5 presses)
  • Select "Asus EZ Flash 2 Utility"
  • A screen will appear allowing you to select the BIOS file. The USB pen drive is normally highlighted first (FS0:) and you should be able to select the BIOS .CAP file for flashing
  • After selecting the BIOS .CAP file, follow the onscreen instructions.

Tip: Always use Stone Computers official BIOS to prevent your copy of Windows re-requiring activation. This is especially important if you are using a Stone Computers factory image or OEM installation of Windows.
