How to use
Power down the system and disconnect it from mains power before beginning. Remove the front bezel or access panel according to the service manual for the specific Lenovo model, taking note of retaining clips and screws. Disconnect the existing control board’s cables and carefully extract the module. Align the replacement Lenovo Function Board CARDPOP C and connect the factory cables to the original connector locations, ensuring secure seating. Reinstall the bezel or access panel, reconnect power and verify that function keys, LEDs and front-panel controls operate as expected. If any functions do not respond, recheck cable seating and consult the device service manual for model-specific diagnostic steps.
Usage recommendations
Handle the board with ESD precautions in place; use an anti-static wrist strap or mat. Use only the compatible connectors and avoid forcing cables into mismatched sockets.
