  1. Hello everybody!

    Sorry for my bad english, this is google translate :(

    I have Lenovo x240:

     

    1. Many thanks to Klem. He removed the WWAN and WLAN whitelist in my x240 bios.
    2. I replaced WLAN: old ac7260 with new ac8265 - super !!! I wanted to put ax210, but unfortunately it haven't a drivers for Windows 7, for Windows 10 only.
    3. Replaced WWAN: old em7345 with new em7455 - problem:
    • when turning on or restarting the x240, a sound signal and an error appear:

    2101: Detection error on SSD1 (M.2)
    Press Esc to continue

     

    • after pressing ESC, Windows boots, em7455 works fine !!!

    In interface m.2, the bus is configured using the output pins of the plug-in modules. See Product Technical Specification em7345, em7455, ssd-disk:

    Spoiler

     

    em7345:
    CONFIG_3 (01) - (GND in default module configuration)
    CONFIG_0 (21) - (NC in default module configuration)
    CONFIG_2 (75) - (GND in default module configuration)
    CONFIG_1 (69) - (GND in default module configuration)

    em7455:
    CONFIG_3 (01) - (NC in default module configuration)
    CONFIG_0 (21) - (GND in default module configuration)
    CONFIG_2 (75) - (GND in default module configuration)
    CONFIG_1 (69) - (NC in default module configuration)

    SSD-disk:
    CONFIG pins are set by the SSD to inform the host if the drive wishes to use the SATA or PCIe signaling scheme. SSD-SATA pull pin 1, pin 21, pin 69, pin 75 to Ground.

     


    To eliminate the sound signal and the appearance of an error, it is necessary to glue or paint over with varnish 21 pins of em7455.
