Sometimes it looks like a student’s Chromebook is broken—maybe the screen is upside down, the fonts are enormous, or everything suddenly looks dark and spooky. But often, the issue isn’t with the device itself—it’s the result of students changing settings, either out of curiosity or as a way to disrupt class.
From flipping the screen with a keyboard shortcut to enabling high-contrast mode or zooming in until the taskbar vanishes, students have figured out how to access various Chromebook features that can make their device look and act strangely. These changes often leave teachers scratching their heads, thinking something is wrong with the Chromebook, when in reality, it’s just a matter of a few clicks or key combos.
