Override system power-saving settings.
This extension makes it easy to temporarily disable power management on Chrome OS.
It adds an icon in the upper-right corner of the browser that can be clicked to switch between modes where the screen is kept on (sun icon), the system is prevented from sleeping (sunset), or power-saving settings are left unchanged (moon).

Frequently-asked questions:
* Will this extension prevent a Chromebook from suspending when its lid is closed?
No, but if an external display is connected, recent versions of Chrome OS will remain awake when the lid is closed.
* What's the difference between the "screen is kept on" and "system is prevented from sleeping" modes?
When the system is prevented from sleeping (sunset icon), network connections will remain active; this may be useful if using e.g. the Secure Shell app. The screen will still dim and turn off eventually, though. In the "screen is kept on" mode (sun icon), the system will avoid sleeping and the display will additionally remain on.
* What do the icons mean?
The sun icon means that the screen will be kept on. The moon icon means that the system will behave the same way that it would if the extension were not installed. The sunset icon is a middle ground: the system will avoid sleeping (as described above) but the screen will still turn off.

Release notes for version 1.8 (1.7 was never published):
Removed windows.onCreated hack added to work around http://crbug.com/222473 on Chrome OS.
Release notes for version 1.6:
Removed scary "tabs" permission. (Technical details: There's a bug where Chrome doesn't notify extensions after the user logs in on Chrome OS. This extension loads its saved state whenever a window is created instead. The chrome.windows API is documented as requiring the "tabs" permission but listening for window creation appears to work without it.)
Release notes for version 1.5:
This version fixes a bug where the previous mode would not be correctly restored after logging out and back in.
Note also that only the "keep the screen on" and "unchanged" modes are available in Chrome 26. In Chrome 27, the "prevent the system from sleeping" mode is also available.

- (2023-09-08) Daniel Martinez: Doesn't do anything and my computer still idles within 10 minutes.
- (2023-08-16) Trilliant Machinemetrics: Is there anyway to revert back to an older version? I'm using it on a chromebit that doesn't update any more and since this app up dated I can no longer use it.
- (2023-08-15) Erich Pechin: Worked great for a long time. Recently, it stopped doing anything. Click on the icon, nothing happens.
- (2023-08-05) Shadow's Pancakes: Doesn't work anymore >:(
- (2023-08-04) Meh Bleh: Don't know what happened to it today (August 4th, 2023) but it stopped working completely. The icon that normally stayed as a sunny day it isn't clickable anymore and it changed to the picture of a moon. Right-clicked to check options and it they are grayed out.
- (2023-07-18) Brock Dillon: it really works but also if you put it on the day icon your battery goes down significant amount
- (2023-05-24) Denise Allen: Worked great for a while, but lately it seems to have lost its oomph.
- (2023-03-08) 허진행 (미원): 매우 잘 작동합니다! 다만 이 확장 프로그램을 활성화 했다는 사실을 잊는다면 크롬OS의 절전 정책에 버그가 있거나 장치에 말썽이 있다는 것으로 오해 할 수도 있음을 기억하십시오! 그 만큼 잘 작동한다는 뜻입니다! It works very well! Just remember that if you forget to enable this extension, you could mistake it for a bug in ChromeOS' sleep policy or something wrong with your device! That means it works just as well!
- (2023-02-17) J J: I have used this extension for many years and I love it, but recently when I have it set for the computer to stay awake and have the monitor sleep, the monitor doesn't want to wake up again when i move my mouse or touch any key. It has done this several times now. This extension has to be the problem.
- (2023-02-10) vivek raj: not working
- (2023-01-15) That Random Arras: It works great but I think it's using a lot of battery? Or it could be the screen uses a lot of battery.
- (2022-12-19) Fatima Huerta: Ignore the bad reviews, honestly I just use this to keep my computer on, idk about the other options but if you're looking for a way to keep your chromebook on, I recommend this extension.
- (2022-11-22) Shawn Starr: Seems to work fine on my Chromebook, this is exactly what I needed!
- (2022-08-26) Sourav Naskar: The day variant is not coming even after clicking on the icon . The screen goes off after 1 minutes as usual. it does not work.
- (2022-06-29) F NE: It works, life saving! It's pretty insane that we have to install someone's extension just to prevent the screen from sleeping... Google no longer provides any way of preventing the automatic logout which then requires the password. Total madness. Let me control my stuff Google, if I want to configure something I know why and you don't. The more I use ChromeBook/ChromeBox computers and the least I want to ever buy one again.
- (2022-06-02) Ikenna Mbonu: Great utility! Does exactly what it says, as it says.
- (2022-04-05) Raj Kumar: Not working.......
- (2022-04-05) 즐거운유튜브: wow
- (2022-01-30) Ruso Anto: Not working
- (2021-08-12) defwee fecsdeds: Amazing and very efficient!!!
- (2021-05-31) Daniel Deskins: For some reason the screen wont dim or turn off with the sunset mode on any clue i may be doing something wrong
- (2021-02-26) Ning Cao: good!
- (2021-02-22) raul aguilar: its useless
- (2021-02-09) Thomson Manoj: This is easy and simple to use, and works perfectly
- (2020-12-06) Shriya Sharma: Did not work at all. My computer shuts off even when it's on. Would not recommend. It may be because I have windows. If were to suggest, you should make the screen stay awake even on Windows, or fix it. Thank you for your time and have a nice day.
- (2020-11-28) David Cohen: Grateful despite no options, no suns or moons. Vids keep running w/ closed lid, but, still 10x better than incessant sleep/wake when using multiple chromebooks. Grateful and triple-thanks
- (2020-11-05) Henry Toilet paper eater: It does nothing.
- (2020-10-17) MyLessonsTV: Chromebook c710...crashed after closed. Tested. USB (Logitech, Labtec) keyboards stop working.
- (2020-09-03) Daniel Bordner: I use this extension probably more than any other. Sometimes you just can't have your device going to sleep.
- (2020-08-05) John Kelly: Worked great but now ChromeOS is reporting 'this extension contains malware'
- (2020-04-11) wilmer reyes: muy bueno
- (2020-03-24) Matthew Blecker: Works exactly as advertised. This is essential for keeping SSH connections alive, or other long-lived connections. I still wish Chrome OS had more flexible power management options built-in, including allowing Chromebooks to only lock on lid closed (staying awake). No extension can prevent sleep on lid closed, unless an external monitor is connected.
- (2020-01-01) Gary Bishop: Works great. I use it all the time.
- (2019-12-22) Richard Stephens: Does what it says it does - Chrome OS would be far less usable without it.
- (2019-12-22) Jack Leahy: Does not work on Pixel Slate. Screen saver turns on in 6 minutes despite having set the extension to the keep awake setting unless I push a button or brush the track pad. It's a distraction if you want to watch any video that is longer than 6 minutes.
- (2019-08-26) iNoobBoi: Quite efficient and compact.
- (2019-08-14) Tahmid: Works
- (2019-06-08) John Paul Villanueva: I don't know how these 3 options works. No clear instructions or settings. I just clicked the daylight since I want to keep my screen open even if its locked. So 5 stars!
- (2019-05-16) kath nh: Now I don't have to sign in every time I walk away for a minute!
- (2019-04-28) Alaric Titeux: Bonne idée, c'est même complètement débile de la part de google de ne pas avoir un minimum de gestion à ce niveau dans les chromebook. Par contre l'appli à empêché l’écran de se rallumer après avoir éteint et redémarré l'ordi. obligé de faire un recovery via usb... pas content du tout!!!
- (2019-03-29) Pam wetherall: I 100% rate this as a must have for us filmeze and youtube watching video's buffs and other activities. etc...Before I had this ext added, it drove me crazy, well, I have now been using this ext for more than 3yrs and now I couldn't do without it now, it's like going out naked, you wouldn't do it would you,,,
- (2019-03-10) Joshua Vogel: Does exactly what I needed: Keeping the screen on while cooking. Great that it doesn't require any permissions. Found the icon a little confusing at first, thought the rollover text showed what mode the extension would go to if clicked, instead it tells you what mode it's currently in.
- (2019-02-27) Adrian Ma: Awesome, great for presentations and heavy duty work. Would be excellent if you offered a timed option to automatically switch back to regular mode after so many minutes or hours in case I forget to set it back manually.
- (2019-02-13) AdMan The Lab Rat: I used it on ou ACER CB5-3111,s and I Love it because using Chrome on a locked do it overrode wn Win7 work box, this allows me to override My former employer's group policy and kills our mandatory 5 minute timeout policy (I installed it on my ACER CB5-311, then enabled Chrome to also synch my extensions and apps, then logged in at work on my Win7 box, firedup chrome and now I'm in control!
- (2019-01-27) Marcelo Iturbe: Simplemente funciona.
- (2018-12-04) Steven James: OMG this actually worked!!!! This just saved me a ton of headaches from a really inconsiderate policy.
- (2018-11-29) Big lester: the option is built in but u got to know how to find it and you all rock.
- (2018-10-01) Dave: Lid has to be opened and closed each time I use it connected to TV HDMI. Would love to just click my mouse and have it wake the screen. fail. Chromebook
- (2018-09-30) Jacob Katz: It doesn't work on my Acer Chromebook. I wish it would, the screen keeps shutting off while I try to listen to a music video.
