M.2 B SATA socket stopped working in LP3

Hi, Sirs,

SATA M.2 B socket on LP3 stoped working after I changed M.2 SATA SSD to SIM7600G-H LTE module. Can you, please, advise me, how to check, if SATA socket if fine ?

In the BIOS, Advanced folder, SATA device is not detected. Device manager does is not showing new device with SIM7600 in the SATA socket.

When I tried to return back M.2 SATA SSD to SATA M.2 B socket, it also stopped working and there are no changes in Device manager. 
At the same time, this SSD is recognized via external USB adapter, supporting M.2 SATA 2280.

I am ready to send you LP3 for diagnostic and repair. It seems to me some electrical circuit happened.

What I need to do ?

Thank you for your help in advance.
