I have moved a EM7305 from my old Fujitsu laptop, to my new Lenovo T14 AMD. But Windows does not recognize it at all. Nothing in Device manager. It worked in the Fujitsu before moving it. I have installed the generic Sierra driver for it, but that did not change a thing.
Please note that the EM7305 module does not have an independent power supply and make sure it’s connected to your Lenovo host in the right way.
After module powered on, please help to check Module power state so that you can see it under Device Manager, it should be Normal(Default state) or Low power (Airplane mode).

If it does not work, please upgrade module to latest FW and re-install driver for window
- Latest FW: https://source.sierrawireless.com/resources/airprime/software/airprime-em73xx_mc73xx-fw-package-latest-release/#sthash.U8xSdYAB.dpbs
- Driver for window: https://source.sierrawireless.com/resources/airprime/software/airprime-em_mc-series-windows-drivers-qmi-build-latest-release/#sthash.8QeV6FOg.dpbs
Also give a try on a “Scan for hardware changes” button of Device Manager
