Lenovo Miix 510 notebook external keyboard can’t be repaired
The WWAN position on the motherboard is empty, and even the slot is not installed. Check that the pins 7 and 9 of the drawing correspond to the two data pins of USB, cut off the wiring of the data terminal of the keyboard interface, and fly the wire to the pins 7 and 9 of WWAN. Installation test, the external keyboard can be used, fault repair!
