MC14 + Windows WON'T Auto SLEEP/suspend
jacky:
With MC14 loaded, the PC will not sleep automatically after the set windows power management sleep timer counts to zero.
Here are the results from powercfg -requests

Can MC14 please allow auto sleep?
Matt:
Hey, I didn't even know about the "powercfg -requests" switch. That's neat!
But to your point, why is opening a file preventing a sleep? I mean, we'll read the file if the computer is awake, but it's not a reason to _keep_ the computer awake. Does anyone have any more information about this?
We have special sleep handling code to prevent sleep, but it only engages when you're recording television, watching something fullscreen, etc.
Thanks.

You can either set this via the Group Policy Editor (gpedit.msc), or you can enable it to appear in Power Properties by opening Regedit and going to:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\ Power\ PowerSettings\ 238C9FA8-0AAD-41ED-83F4-97BE242C8F20\d4c1d4c8-d5cc-43d3-b83e-fc51215cb04d]
In there, set Attributes to 0 (the default value is 1, which means hide).
Now, when you look in Power Properties you should see an option to allow sleep whilst network files are open (sorry, can't remember the precise wording because I'm on my Vista machine right now, and it doesn't support this setting as far as I can tell). Set it to Yes.

However, in 1-2 hours, the system has went to sleep and I can't awake it because the system hangs... I have upgraded the motherboard BIOS (Asus P6T) to the newest one, and in power I have the following configuration:
Suspend Mode: Auto [available: S1 (POS) Only; S3 Only; Auto]
Repost Video on S3 Resume: No [available: No; Yes]
ACPI 2.0 Support: Disabled [available: Disabled; Enabled]
ACPI APIC Support: Enabled [available: Enabled; Disabled]
Please help me, I don't know what to do.
Thank you very much.

However, it applies only to Windows 7. But I'm using Windows Vista. Please find a solution for this problem.
Matt:
Would you mind trying a local library (i.e. C:\) to see if the issue only applies to network libraries?
Most files we don't keep open. I wonder if the read matters, or just files kept open? We keep lock.jmd open because that's how we handle multiple clients connecting to a single shared folder.
Thanks.
MusicHawk:
I think I have the same experience, using a local library, MC14, Windows XP or Windows Vista.
Consider these three MC computers on my home LAN:
PC1 - Manage LOCAL drive music library. No remote server access, ever.
PC2 - Play LOCAL drive music library. No remote server access, ever.
PC3 - Manage LOCAL drive photo library, AND usually run MC server, in case I want to view photos on another PC.
On any of these PCs, if MC is open in a visible window, it seems the computer will not auto-sleep/suspend. I've tried every Windows setting, nothing matters.
On PC1 and PC2, MC is not doing anything explicitly -- no network access, no server connection, etc.
On any of the PCs I can manually suspend/sleep and it seems to stay asleep. But they won't go there when Windows counts down and tries to force sleep.
If MC is not the foreground window, *sometimes* the computer will sleep, but not reliably. If MC is not open, the PC goes to sleep on schedule.
Even with MC open, other Windows timer actions seem to happen as expected -- display off, drive off. Only sleep fails.
(In fact, the display will go off after a specified time even while MC is actively playing, an "opposite" annoyance. During the day I have to remember to jiggle the mouse of my playback PC now and then to remind Windows to keep the monitor on.
I wonder if MC's Auto Import is doing folder checking in a way that prevents sleep?
OR, since there IS an MC library server on my network, does every MC client keep communicating with it, even when MC is not using the remote library? Does MC server advertise itself, or does MC client send a query?
OR, something else to check?
