So after I added the SSD to the HTPC and\u00a0moved my hard disk into the\u00a0 NAS drive, I began to notice the machine no longer automatically goes to sleep.\u00a0\u00a0\u00a0 If I hit the power button (set to sleep) or run it from the command line (%windir%\\System32\\rundll32.exe powrprof.dll,SetSuspendState Standby<\/span>) the machine goes to sleep just fine, but won’t do so automatically.<\/p>\n

Mucking with powercfg (which is a very interesting program BTW.\u00a0 Run powercfg \/? if you’re not familiar with it) I found the following:<\/p>\n

powercfg -requests<\/p>\n

[DRIVER] \\FileSystem\\rdbss
\nA file has been opened across the network. File name: [\\medianas\\Photos\\blah\\blah\\blah\\IMG_9088.jpg] Process ID: [4456]

\n….<\/p>\n

So basically, the Media Center Screen saver is actually preventing the system from going to sleep because it has all these photo files open across the network.\u00a0\u00a0\u00a0 I really like the screen saver, and I don’t want to suck up space on the SSD with photos.\u00a0\u00a0 What to do?<\/p>\n

It turns out, there’s a hidden setting in powercfg which will allow to enable sleep when files are open over the network.\u00a0\u00a0 I assume the option is hidden by default because most folks wouldn’t understand what “remote opens” were.\u00a0\u00a0\u00a0\u00a0 There’s a very helpful blog post<\/a> here which explains a number of hidden power\/sleep settings in gory detail.\u00a0\u00a0 Low and behold after importing the registry file (run regedit as administrator):<\/p>\n

Still need to do a little more testing but I figure this should do the trick.\u00a0\u00a0 Just a couple more handy commands for my own reference:<\/p>\n

Put the computer to sleep from the command line<\/p>\n

%windir%\\System32\\rundll32.exe powrprof.dll,SetSuspendState Standby<\/code><\/p><\/blockquote>\n

What was the last reason the PC woke up from sleep<\/p>\n

powercfg -lastwake<\/code><\/p><\/blockquote>\n

List all the requests from processes to prevent the computer from sleeping:<\/p>\n

powercfg -requests<\/code><\/p><\/blockquote>\n

Analyze any power usage issues the system might have<\/p>\n

powercfg -energy<\/code><\/p><\/blockquote>\n

See “powercfg \/?” for more info.<\/p>\n","protected":false},"excerpt":{"rendered":"
