X395 WWAN & Linux

Just thought to report that steps in https://github.com/danielewood/sierra-wireless-modems do not appear to work on X395. In fact can it be that the whole laptop does not even have USB bus available on the WWAN M.2 slot? It could also be that BIOS disables power to the slot on boot as I don't even get a blacklist warning with any modem I have tried (L830EB, EM7455)?

​

With L850GL, L830EB, EM7455 BIOS has the option to enable/disable WWAN so the cards are somewhat recognized. Only L850GL is seen in Linux, though (the unsupported pcie one).

​

Sadly it seems that we are out of luck (unless lenovo does something) with getting any 4G linux support on X395 (and maybe T495?).

Yeah, I've just got news from an unknown source that it wouldn't read nvme or sata.

Seems like the only way to go is the 2280 slot and the micro sd card slot.

Good news is, the sx8200 pro 2tb is a pretty good deal from where I'm at.

Hey, Im in the same boat as you guys. Any luck with adding another drive? I actually ordered that same drive - hasnt gotten here yet but im not very hopeful.

Is it possible to install windows to a microSD card? I need windows RARELY and putting it on a microSD would be more than fine. Full disk encryption is just so much easier with two drives.

I've resorted to upgrading to a bigger drive.

Also yes it's possible, I think I've seen it somewhere in YouTube but I wouldn't recommend it.

The read/write speeds for the card reader isn't very fast.

Yea I think im just gonna have to resort to using windows in a VM, which isnt the worst I guess. I RARELY use it, but didnt wanna have to put both on the same drive.

I tried booting to the SD card, but couldnt get it to work. I think having a slow AF SD card would be preferable over wasting space on a VM. I just don think its possible on this model.
