Full summary	Keep Awake is a straightforward Chrome extension designed specifically for Chrome OS users to temporarily disable the system's power management settings. With a simple icon in the browser toolbar, users can toggle between three modes: keep the screen on, prevent the system from sleeping, or leave power-saving settings unchanged. The extension offers flexibility for different needs: the 'screen kept on' mode ensures the display stays active, while the 'prevent system sleeping' mode keeps network connections alive though the screen may dim. The intuitive iconography (sun, sunset, moon) clearly indicates the active mode. Keep Awake is especially useful during presentations, downloads, or when using apps like Secure Shell that require constant connectivity.	Caffeine - Keep Awake is a versatile Chrome extension designed to prevent your computer or display from entering sleep mode or dimming. It offers two operation levels: display level, which stops monitors from dimming or screensaving, and system level, which inhibits the entire system from powering down or entering hibernate mode. Customize the active duration from 5 minutes to 24 hours, allowing flexibility for various tasks. Ideal for uninterrupted downloads, presentations, reading e-books, or when you need to temporarily keep your device awake without altering your OS power settings. Simple activation via toolbar button with easy toggling and context menu options make it user-friendly across PC, Mac, and ChromeOS devices. Note that sleep prevention when the lid is closed varies by OS.
