If certain Fn keys still work, it could be a sign that your keyboard needs cleaning . If you don't clean it regularly, your keyboard can collect a lot of dust and prevent the keys from working properly. If you're knowledgeable enough, you can clean your laptop yourself , as long as you have the right tools.
