First, you’ll need to open Control Panel. To make things easier, type in “power” into the search box, and then click on “Power Options”.  (for command line hackers, you can just type powercfg.cpl,1 in an admin mode command prompt and get right to the good stuff)

In the resulting screen, click the “Change plan settings” link underneath the currently selected plan.

In this screen, click “Change advanced power settings”.

Now you’ll need to browse down to Multimedia settings \ When sharing media.

Change both of the options to “Allow the computer to sleep”. The menu item for Sleep should be back to normal.

Funny side note: This article was in response to an email from a reader, who signed it “Sleepless in Jersey”. Thanks for the grin =)
