my thought was I wonder if there is a way that when my app shuts down I send a final command to the Arduino to switch off or somehow end the program loop.??
Thanks @Grumpy_Mike,Well the computer is an Alienware Steam Machine running Windows 10Connected to the Arduino is an LDR Sensor, a DS1820 Temperature sensor module,Some button inputs.... the rest is information that gets sent to the Arduino when our app is running.Arduino is connected via the USB port, no other power connected.
I just did a clean install of Windows 10 on the Alienware Steam Machine.
Is sounds like the Steam OS is gone, and you are running only Windows 10 on the original hardware.Is it only the arduino attached to usb which prevents the computer from turning off? What about a usb hard drive or other usb component?
I finally gave up and had to use Google. The machine is made by Dell and runs Lenix. Windows is running under LENIX, so you problem is with Lenix, not Windows 10.Paul
