The Nintendo Switch has another neat little quirk behind it. In addition to having a hidden copy of Golf, the classic Nintendo Entertainment game, which originally released in 1984 embedded into the system’s firmware, the Nintendo Switch does something very polite when you put the console to sleep.

Embedded into the OS kernel, when the Switch is put to sleep, the power management controller is sent a string saying “Oyasumi,” which means good night in Japanese. When you wake the system up, the controller once again sends a signal, this time saying “Ohayo,” or good morning.
Pretty cool, Nintendo! The developers sure had a lot of fun designing the Switch, which recently hit 10 million units sold!
