When you travel “home” for the holidays, that often means visiting older relatives, who would like you to to take a look at what’s wrong with their computer, phone, TV, or other tech devices. Geeks make jokes about this constantly, so when I saw the headline as written above, I thought this might be a comedy list about how you can mess those things up so they’ll never ask for your expertise again. No, this is a serious list that would be seriously useful in getting things situated at Grandma’s house. It would also be a great New Year’s list for yourself, as you have put off some of those tech maintenance tasks for too long. Start 2020 fresh and secure with the tech tasks listed at Gizmodo.
