Ecobutton

Ecobutton is a USB button which you can get for about $6 USD. The "eco" software it comes with is pointless. It puts your PC into S3 sleep mode, which you can do by pressing "Sleep" on your keyboard. But you can use the button for your own purposes, such as launching apps, backup scripts, etc. The button simply calls an exe called ecobutton. Create a batch file called ecobutton.bat with a link to your app and put it in Windows' path. You can now launch your app with this button. If you don't want the light effects, open up the casing and solder out the 3 SMC-type LEDs labeled LED1, LED2, LED3.
