Keep system or display awake by overriding power-saving settings, which prevents dimming of the screen, or starting a screen saver
This extension keeps your operating system from going into hibernate or sleep mode. There are two levels of operation:
1. "Display": prevents a single or multiple monitors from dimming or displaying screensavers
2. "System": prevents the entire system from going into the power-saving state
1. Operates on display or system level
2. Keep the system awake for a specified period (from 15 minutes to 24 hours) and allow the system to sleep afterward. This is useful if you have an ongoing downloading job on your browser and you don't want it to get interrupted.
The extension only offers a toolbar button that is inactive by default. You can click the button once to active the keep awake state and prevent from sleeping. Another click will release this state back to the default. To change the level, use the right-click context menu items. This extension does not alter the power-settings of your computer (PC, Mac, or ChromeOS) when it is disabled. However, if it is enabled, the extension overrides these settings and prevent it from going to sleep mode.
Will this extension prevent my computer from suspending when its lid is closed?
It depends on your operating system. Some operating systems allow background activities to perform even if the lid is closed. Some others do not allow it. If you have an old Chromebook, when the lid is closed, the operating system suspends all activities.
Why do I need this extension:
1. You have an ongoing download and you don't want the network connections to break
2. You are not going to touch the mousepad for a while, but you need to use your screen during a presentations
3. You are reading an e-book or PDF and you don't want the screen to dim
4. You want to temporarily keep the computer awake without altering the power-settings of your OS.
