    Do do the maintenance on my htpc I use RealVNC. So why stand up and switch the htpc on. There must be a way to do that with software.

    Just send a magic packet :arrow: Wake on LAN (WOL) :!:
    (Requirements: ATX power supply and wol capable LAN adapter/mainboard)

    How to do that?

    Get a wol program. Here's my recommendation:
    PowerOff 3.0.1.3
    http://users.pandora.be/jbosman/applications.html



    Start PowerOff and select the action "Wake-On-LAN". You have to set the remote computer. In the dialog you fill in IP adress and subnet mask. With the settings you can lookup the MAC adress of the LAN card in the htpc. Execute, that's it...

    You can also use command switches with poweroff. Just put a shortcut to poweroff on your desktop and add these switches:

    C:\Program Files\PowerOff\poweroff.exe wol -ip 192.168.0.1 -subnet 255.255.255.0 -mac 123456789012
    (For 123456789012 enter the MAC adress of your LAN adapter.)

    With that shortcut you switch on your htpc with just one click...

    You can find some other programs here:
    http://www.depicus.com/wake-on-lan/
    http://sourceforge.net/projects/wakeonlan/

    How do I find out the MAC adress?
    At the command prompt type ipconfig /all. The pysical (MAC) adress is displayed in the list.

    Great Tip. My Motherboard (ASUS A7n266-VMAA) also has a Wake On Keyboard option in the Bios. Ive switched it on but since I use a remote control (custom made connected to my Serial Port for use with WinLIRC), I was wondering is there Any way to send a key press when the power is "off" thru the serial port to emulate the keypress on my keyboard?

    Great tip! Works good.
    I also have a problem with starting with the remote control.
    My remote control is usb. I can wake up the computer with an usb keyboard, but I can't get it to work with my USB remote control.
    Anyone a suggestion for that?

    I'm not too sure where you're from, but I built my own IR receiver (bought a kit from JayCar (AUS)).

    The kit connects to an internal or external COM port but also has the ability to connect to the WOL header. You can then program a command from the remote that will power on the PC.

    Here's a link to an article http://www.siliconchip.com.au/cms/A_30653/article.html.

    You can't read the full article if you use a direct link but if you google for "pc remote silicon chip", you should be able to find it.

    It should give you a full list of parts etc so you can build it yourself. I've got mine sitting in an empty 3.5" bay.

    Thank you for the excellent tip PJ. I (from US), built my reciever from parts at radio shack costing about $6 total. Here is the site:

    It works well but now you got me too excited. Connecting the serial to WOL pins makes sense. Wasn't thinking of this before. Thank you very much.
