Hello, I just bought an MC7710 module for my thinkpad X230 (with the right FRU for Lenovo)
The laptop started and I saw several devices called MC7710 in devicemanager, I loaded the drivers but there were stille problems in devicenamanger. So, I downloaded the firware update from sierras homepage, it loked like the firmwareupgrade went ok, said something about “not able to open com-port” after the flashing was done??
So, I restared the laptop and the MC7710 wasen´t visible any more?? Tried to install Ubuntu and did and ls -l in /dev/ but found no references to MC770, should I look for something else in /dev/??
Have I bricked the MC7710??
And if I have bricked it, is there in any way possible to fix it??
Got home from work now, a dmsg shows this

What do you think??
Ok, so now i took the modem to work and it shows up in a co-workers HP?? The HP as about as old as my X230 i think. But it does´nt work, it only shows upp in “dmesg” and lsusb
So i tried in another HP machine with win7 and it found the modem, installed drivers and I can connect to internet also. But, I cant connect to the modem with putty, have tried COM4, COM5 and COM6?? What am I doing wrong here??
And, should i run the modem in DIP mode or QMI?? I think it is i QMI now??
If someone reads this and have atleast one answer to the questions above please respond.
Wil install the card in my laptop tonight with a fresh install of win 10 and hope for the best…
Ok, so I got home, installed the device and guess what, it showed up in windows!
Happy days until I restated the laptop and the mc7710 was gone…
The only thing that is left i devicemanager is some Sierra wireless location sensor??
It´s like the device enters sleepmode?? I have tried disable/enable the wwan in bios but it does´t help.
Please advise?
