I have a W541 running Windows 7 (64bit). I've found 'Sierra Wireless GNSS Sensor EM7345 4G LTE' appearing with exclamation mark icon in the device manager. Lenovo solution center also shows it as disabled device. I have downloaded and installed latest driver (2.17.10870.4454). After installation the device seems fine in device manager but as soon as I restart the notebook the device appears again disabled in the device manager.
I’ve just found in the README file the W541 is not listed as supported model by Windows 7. According to this file W541 is supported by W8 or W10 but unfortunately I’m not able to install any other OS on the laptop.
Can I expect to have support for W541 with W7 in a future software release?

I'm having the same problem with my Sierra Wireless 7345 on a W550s running Windows 10. It came with the laptop, so I'm sure it's supposed to be compatibile.
I think it's a driver compatibility problem.
Unfortunately, I've just chalked it up to the "Windows/Lenovo" tax - some things work, others just don't. I've gotten no reponse from Lenovo.
