Remote start up a machine that is in the shut down state? [duplicate]

Yes you can.

I see multiple solutions.

First: You can achieve this through LAN or even Internet.

For this, you have to open your BIOS settings and turn Wake On Lan (sometimes it's called Resume On Lan) on. But that's not enough. You have to turn Wake On Ring or Resume on Ring as well (if you have), actually this may be called differently. So you would probably need to turn ALL Wake on Lan settings in BIOS.

Then, you use special software (I use Linux and using wakeonlan script, search in Google for Windows programs). It's easy actually you can write your own.

All you need now is to know your MAC address. Then turn your computer on. in my case I do this: wakeonlan 00:ff:ff:11:33 (where 00:...33 is MAC address)

Second: (but not for a remote start up!) Windows supports on schedule power on. but in this case you need to set your Machine into StandBy mode, rather than power off.

As a last resort you could try ITAPPMONROBOT ;-) http://thedailywtf.com/Articles/Classic-WTF-ITAPPMONROBOT.aspx

A computer that is shut-down but the PSU is still on, still has a 5V stanby line feeding power to the motherboard. (it really isnt all off)

A wake-On-Lan feature in many motherboard bios, would usually be used to awaken the machine, as the Nic (the network connection) is one of the things that can be powered by this small ammount of 5V power.

Once the Wake-On_lan Feature is enabled in the bios, the computer is sent a special packet (chunk of data) called a "Magic packet" and the computer will wake up, and boot and all. after a while it is then accessable.

http://en.wikipedia.org/wiki/Wake-on-LAN it doesnt always work as simply/correctally as i may have described it :-) aparentally there are even methods now to achieve a wake based on wireless, but this is beyond my skill now.

ADDED Bakytn reminded me of one more thing that could be very important. the hardwares settings. in windows, The properties of the network device, when in device manager.

or if you go through "Network", you bring up that connections properties, and hit "configure" for the network device, then go to advanced. The configuration items for the hardware itself. (way down deep) There all all sorts of Hardware setting in there, and the Wake features could be off by default. Be sure to look there if you get no results.
