Câble eDP Lenovo 01YU991 pour écrans tactiles

Replacement eDP cable Lenovo 01YU991 for touch screen displays connects a laptop's touch panel to the mainboard, transmitting video and touch signals between the display assembly and system board.

How to use

Power off the laptop and remove the battery if possible before beginning. Access the display assembly according to the laptop service manual, carefully detach the bezel and display panel to expose the existing eDP cable connections. Disconnect the old cable from the display panel and mainboard connectors, taking note of connector orientation and any retaining clips. Install the replacement eDP cable by aligning and securing each connector, ensuring firm seating and that no pins are bent.
