Is there anything that would cause a Nano not to boot? Every now and then when the power gets reconnected to the nano the light on the board shows green but when a display is connected via hdmi nothing shows. The device is also not connected to the network at this time. The only way to fix is to remove/reconnect power source and then the device will again show the green power light and then the monitor will display the nano. Trying to figure out why I have to power cycle the device every now and then.
