    Power Management can use AMT or WOL to power on computers.


    Both methods can be used to wake a computer from a Hibernate, Standby, or Power Off State.   When using WOL, the Power Management "Turn On" task functions in the same way as right-clicking a computer in the Management Console and selecting "Wake up".


    However, the scheduled task that the Core Server runs always sends the WOL packet from the core server.   Right-clicking a computer from a Remote Console and selecting "Wake Up" will send the packet from the remote console.   So you may notice times that the Scheduled Task from the core server does not work, and the Right-click "Wake up" option does work, or vice/versa.


    A broadcast WOL packet is sent from the core server to the target node.


    Routers in the environment must be configured to pass WOL (Wake On LAN) packets for the Core Server to be able to wake clients on subnets that are on the remote side of the router.


    The remote computer must also have Wake On LAN capability for this to work properly.


    This activity can be viewed in the console log in \Program Files\LANDESK\ManagementSuite\Console.exe.log.




    7/16/2009 5:11:36 PM : WakeOnLan.Wakeup(): Sending Packet - ipAddress =, subnetAddress =, macAddress = 000C29B6B108, port = 0



    This packet is generally sent to the first bound adapter as gathered by the LANDESK Inventory.


    This shows in the Inventory Tree for a client here:






    [Bound Adapter]


       [IP Address]


    Note: If the adapter order is incorrect, which can be caused by the installation of software that installs a virtual driver or other reasons, you can change the adapter binding order.


    The following describes this process:

    Changing the order of network adapters in Windows XP

    1. Click Start > Control panel > Network Connections.
    2. Click the Advanced Tab.
    3. Click Advanced Settings.
    4. Click Adapters and Bindings.
    5. Change the order of network cards as required using the Up and Down buttons.

    Changing the order of network adapters in Windows 7

    1. Click Start > Control Panel > View network status and tasks > Change adapter settings.
    2. Press and release the Alt key.
    3. Click Advanced > Advanced Settings....
    4. Change the order of network cards as required using the Up and Down buttons.


    Note: When scheduling a Power On task from the Power Manager Tool, it will initially create a task called the name of the Power Scheme name.   After the task has been successfully deployed to a target node, a second task called "Power Scheme Name (power on)" will appear.   This will run regularly on the Core Server according to the schedule set in the Power Policy.


    A common problem with the Power On task, is if the "Wake up devices - does not apply to unmanaged devices" options gets checked in the Task Properties. This will wake the computer and immediately turn it back off. This is because the default behavior for this wake up option will return the computer to the state it was originally in.




    This box must remain unchecked.


    The Turn On task has a hard-coded wake up function in it, so checking the "Wake up devices" option is not necessary, and as stated, will turn the computer back off.
