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?
