Reminders about updating the laptops is a good one as I've noticed a lot of laptops running sluggish lately. (A resource is linked here to share how to update your PC laptop.) Yes, it will take a lot of time to get your machine up to speed, but if you make a habit of doing it at least once per month, you'll find that it will not take as long and your machine will run faster.
Another good reminder is the subject of pirated materials. You need to make sure that you do not have illegal downloads of music, movies, or even...teaching resources. Believe it or not, if you have paid materials from Teachers Pay Teachers that a "friend" gave you, you are stealing. If you want it that bad, please pay for it. If the item was free, then download and share all you want. (Here is a silly comic that addresses the issue of piracy. It might be a good place to start the discussion with your students.)
With all that said, please take a gander at the video that was provide. The theatre department did a great job of addressing the many issues that we as a 1:1 technology school district face on a daily basis. If you want more digital citizenship materials, you can find them in my Pinterest page.
