If you use a browser with the "NoScript" AddOn and have it configured to, as a default, block JavaScript on all but white-listed web pages, then the link's PayWall never is seen and you can read the article.

Q: In the past I would have two or three Google Chrome windows opened with three or four tabs each, and my PC went to sleep as it should, as per my power settings. Now, all of a sudden, with all the same windows and tabs opened, it will not go to sleep. Basically I have to close down Chrome altogether if I want it to go to sleep. Is there a way to override whatever is keeping Windows awake when Chrome is open?
A: This appears to be a known issue with Google Chrome. If you have pages or tabs open with active content like music, videos or animation, this can cause the computer to believe that you are still actively using it and prevent the power mode settings from putting the computer to sleep and even prevent you from manually activating sleep mode.
There are two ways to prevent this from happening.
The first is to manually override the Chrome settings. To do this, click on Start and then type CMD. When you see the CMD icon, right-click it and select Run As Administrator.
In the command window that opens up, type in powercfg -requestsoverride PROCESS chrome.exe awaymode display system, and then hit Enter. This will allow the computer to go into sleep mode with Chrome open and running.
To disable the override, do the same thing and type powercfg -requestsoverride PROCESS chrome.exe and hit Enter.
The second option is to disable this in Group Policy.
Open the Group Policy Editor by clicking Start and typing in gpedit.msc, and then hit Enter.
Open Computer Configuration, Administrative Templates, System, Power Management and then Sleep Settings.
Set Allow Applications to Prevent Automatic Sleep to Disabled. If this is a laptop, there will be two options, one for On Battery and one for Plugged In, so you might want to change both.
