Boot up any of your machine remotely! Able to shutdown (hibernate/sleep next patch!) that desktop provided you have the .jar package started on your machine*. All you need to do is to have a LAN connection to your machine and setup the IP address of it in this mobile application.
Wake-on-LAN works as long as the mac (physical) address of the machine is configured.
Shutdown-on-LAN works only if the IP address is stored and the package below is started. Note that your mobile phone needs to be connected, through WiFi, to the same network of your machine.
Download either package on your machine!
"Shutdown" package @ https://www.dropbox.com/s/zm368l3g8l7ohqo/Shutdown.jar
"Standby" package @ https://www.dropbox.com/s/q07fva9tce6l70b/Standby.jar
Put the package in your "startup" folder if you want it to startup automatically whenever you boot your machine.
*Only in Windows & Unix machines
