Installation & Care Tips
Power off the laptop and disconnect all external power sources, including the battery if removable.
Gently pry up the keyboard bezel or release retention clips to expose mounting screws.
Remove screws and carefully lift out the original keyboard assembly.
Align and insert the Astrum ribbon cable into the ZIF connector, then lock the latch.
Seat the new keyboard module, reattach screws or clips, and snap the bezel back into place.
Reinstall the battery, reconnect power, and boot to verify every key and backlight setting.
Clean with a dry microfiber cloth; avoid liquids, solvents, and harsh chemicals.
