This switcher lets you use a keyboard, mouse and monitor between two laptops. I keep my laptops upright in the tablet/laptop organizer at the back of my desk. Switching between computers is not instantaneous. After pressing the button, the other computer wakes up after a few seconds. However, it works fine. Both computers have their own power adapter (the Surface Book and Surface Laptop have their own power adapters). The switch is used to receive the keyboard/mouse signal to the selected laptop and send the audio/video signal from the selected laptop to an ultra-wide monitor.
