    Lenovo ThinkPad T430 Wifi card not detected [HARDWARE ISSUE]

    I have 2 same lenovo laptops and basically checked everything I could think of.

    1 of the lenovo's work like it should but the other does not recognize the wifi card.

    - I've tested the switch with continuity mode on the multimeter. works

    - When I turn the switch on the working laptop with the same wifi card, there is a wifi light turned on on the working lenovo, the defect lenovo didn't turn on the wifi LED.

    - Both laptops have 3.3V on the first wifi card pin

    - The defect lenovo does not recognize the wifi card in device manager

    What else can I test?
