The keyboard on my laptop is not doing anything when I try to type something. Is there anything I can do to fix it myself?

Hi Karen! The first thing you should do is make sure your laptop is not sitting on a bed or similar surface as this can block the airflow of the fan and cause your laptop to overheat. If your laptop still feels hot on a cool, hard surface like a desk or table, the fan might be either dusty or broken. You can try to clean the fan; however, if you are still dealing with issues, you may need a replacement fan.
