I have a B570 laptop with Windows 7 Professional 64-bit. Nothing has been changed as in all stock parts.
There is a SIM card slot behind the battery and it does not notice or connect.
Does any body know a compatible WWAN Card for the B570
Here's the list of WWAN cards which work with the slot:
The compatible parts can be found from Hardware Maintenance Manual pdf from Lenovo Consumer Support site.
The adapters are not designed for specific mobile operators so it should work without any issue.
