Power off your laptop, unplug all power sources, and remove the battery if removable.
Pry up or release the keyboard bezel to expose mounting screws.
Remove screws and gently lift out the old keyboard module.
Align the Astrum ribbon cable into the ZIF connector and lock it securely.
Seat the new keyboard module, reattach screws or clips, and snap the bezel back into place.
Reinstall the battery, reconnect power, and boot up to verify all keys and keypad functions.
