Keep Awake

Keep Awake插件简介

Keep Awake插件描述

This extension makes it easy to temparily disable power management on Chrome OS.

It adds an icon in the upperright cner of the browser that can be clicked to switch  modes where the screen is kept on (sun icon), the system is prevented from sleeping (sunset),  powersaving settings are left unchanged (moon).



Frequentlyasked 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.

* Whats the difference  the "screen is kept on"  "system is prevented from sleeping" modes?

When the system is prevented from sleeping (sunset icon), netwk connections will remain active; this may be useful if using e.g. the Secure Shell app. The screen will still dim  turn off eventually, though. In the "screen is kept on" mode (sun icon), the system will avoid sleeping  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 f version 1.8 (1.7 was never published):

Removed windows.onCreated hack added to wk around http://crbug.com/222473 on Chrome OS.

Release notes f version 1.6:

Removed scary "tabs" permission.  (Technical details: Theres a bug where Chrome doesnt 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 f window creation appears to wk without it.)

Release notes f version 1.5:

This version fixes a bug where the previous mode would not be crectly rested after logging out  back in.

Note also that only the "keep the screen on"  "unchanged" modes are available in Chrome 26.  In Chrome 27, the "prevent the system from sleeping" mode is also available.
