Keep Awake is a Chrome extension developed by alex313031 that allows users to easily override system power-saving settings on Chrome OS. This extension adds an icon in the upper-right corner of the browser, providing three modes to choose from.

The first mode, represented by a sun icon, keeps the screen on, preventing it from dimming or turning off. The second mode, represented by a sunset icon, prevents the system from sleeping while still allowing the screen to dim and turn off. This mode is particularly useful for maintaining active network connections, such as when using the Secure Shell app. The third mode, represented by a moon icon, leaves the power-saving settings unchanged, allowing the system to behave as it would without the extension installed.

Keep Awake also addresses a commonly asked question regarding Chromebooks suspending when their lids are closed. While this extension does not prevent suspension when the lid is closed, recent versions of Chrome OS will remain awake if an external display is connected.

With its intuitive interface and essential functionality, Keep Awake offers a convenient solution for managing power settings on Chrome OS.
