Couldn't you hard reset your PC by holding the power button until it turns off, waiting 10 seconds, then turning it on again? Or do you need to automate this?

I neede a way to do this when I am away from the PC.

I would recommend getting a bag of pnp and npn transistors, a bread board and following some tutorials before you start trying to interface with pc hardware. Out of interest why are you trying to replicate switch functionality when you could use wake on lan to do the same thing?

Only reason I want this is b/c what if the PC got a hard freeze, and need a hard reset.

WOL can only wake up a PC when it is OFF. In the case that the PC freezes, it would still be considered ON.

Let me know if there are other easier way around this.

In "Public class Program", I have "static Microsoft.SPOT.Hardware.PWM _servo;".
In "public static void Main()", I have "_servo = new Microsoft.SPOT.Hardware.PWM(PWMChannels.PWM_PIN_D10, 20000, 1500, PWM.ScaleFactor.Microseconds, false);"
In "static void button_OnInterrupt", I have "_servo.duration = 1500;". Now it's complaining about "duration".
Error message "Microsoft.SPOT.Hardware.PWM does not contain a definition for duration."

Nevermind. The error is gone now.
Thanks!

Now I have new errors.
