Hi fh902,

It sounds like you're experiencing a couple issues with your MacBook Air, starting with the fans running constantly while viewing an HD video, as well as the battery losing its charge while connected to a charger. We can see how this would have an impact on using your MacBook Air properly. The SMC is a great start to troubleshoot these issues. You've come to the right place for additional help.
