I am not sure. But one thing is that you can power cycle the modem using GPIO.

Like with a physical switch?

These command actually disconnect modem power and then power it on.

echo 1 > /sys/class/gpio/pci_power/value
sleep 5
echo 0 > /sys/class/gpio/pci_power/value

Hi Alzhao !

I think those echo commands are inverted, aren’t they? On my X750s “echo 0” powers down the modem and “echo 1” powers it up.

Maybe. I don’t have the product at hand to verify now.
