Sierra Wireless EM7455 Embedded Module is an LTE Cat 6 SWAP to EM9191 in a FUJITSU 939X?

Does anybody know if it is possible to swap an embedded module to a new one?
Will it suit in FUJITSU LIFEBOOK U939X?
'cause it’s much faster to work, having a 5G connection.

Best Regards,

you might need to check for a number of pin voltage:

I also want to do it on my U938.
Do you have any news?

Have you checked the pin voltage?

no, I haven’t checked it. I have never opened my laptop lid yet

Then not quite sure what will happen for the laptop with the EM91 module
