anyone find a fix for sleep mode yet?

___crisis___1 · Post by **___crisis___1** » Sat Feb 25, 2006 6:47 pm

i still have issues with my pc going into sleep mode... is creamware, or anyone else, going to attempt to do anything about it? or has there already been a fix and i missed it?

this is a very important issue with me, because i leave my pc on 24/7, and it is very loud at night and eats a decent amount of power. i want to be able to have my machine go to sleep after a half hour of inactivity, but still be able to come up ready to record.

just shut it off, ASIO doesn't like it to be inactive too long (I think, and others do), and why import the 24 hrs economy in your private life?

As hubird says, you should really shut it off when not in use (during the night when you're sleeping)

Asside from that, an optimised DAW shouldn't have ANY power saving features enabled apart from maybe your monitor if it's worth a few quid (like a 21"+ flat panel or two) & you want to prolong it's screen's lifespan.

All other power saving & sleep mode features should be disabled in your bios & within XP.
I know it's not eco friendly, but it WILL help with any problems you're having waking it back up from sleeping. We shamelessly often leave our DAW switched on 24 hrs & very rarely does SFP or anything crash or hang on us, because it simply doesn't go to sleep. Of course, this approach will also stress most components in your box, so while you won't have as many problems short term you need to realise that 'power saving' is also 'component lifespan saving' (in theory)

There is no way to fix this. Sleep mode is intended for programs that reside solely in memory, like Word or Firefox or whatnot.

The SFP system is composed of a program that runs in your computer's memory and maintains sample-accurate sync with one or several hardware components that sit on the PCI bus.

So what happens, when you come out of sleep mode, is that the SFP program in memory is expecting to have a fully loaded up and configured SFP card(s), but this card was powered down when sleep mode what activated, so it needs to be reprogrammed.

There is no way for Windows to save and restore the state of the PCI cards, and there is no way for the card itself to save its whole internal state without electricity. There is no infrastructure within Windows that will indicate to PCI devices that Windows has just restored from sleep mode, and could you please re-initialize to your former state-that-you-don't-even-remember-because-when-you-go-into-
sleep-mode-there-is-no-more-electricity-going-thru-the-PCI-bus.

There is no way to fix this without changing the hardware itself (AND Windows, which no one besides Microsoft can do, and they won't), adding some flash memory to "mirror" each of the DSP's internal memory plus the memory that's on the PCB, and likely some more stuff. All that flash memory + infrastructure to reload from saved states is going to run you some serious $$$ (reliable flash memory isn't cheap), make the boards much bigger and less reliable, cost a FORTUNE in engineer's wage (and make them angry from all the nights they have to spend at the office instead of with their family), won't be compatible with current cards, etc etc etc. And anyway the card itself would have no way to know wether it's powering up from a fresh bootup or from sleep mode.

Spare yourself some hassle, and just boot down the machine, and reboot it while drinking your coffee. Or just get some quieter fans/components. Or move the computer to another room.

Which button do we press to keep you there?

Shroomz~> · Post by **Shroomz~>** » Sun Feb 26, 2006 9:18 am

WinXP, SP2 >>>

Control Panel/Power Options

Window called 'Power Options Properties' opens up...>

Under 'power schemes' tab make sure the 'Turn off monitor' & 'Turn off hard disks' fields both read/display 'NEVER' option.

Under 'Hibernate' tab make sure 'Enable Hibernation' is NOT checked.

Under 'APM' tab make sure 'Enable Advanced Power Management support' is NOT checked.

You can also switch off the taskbar icon under the 'Advanced tab.

To completely stop some of the services you might have to disable them in Programs/Administrative Tools/Services.

You may also need to disable bios support of APM, but I can assure you it is possible to solve this, as our system very rarely (if ever) has sleep mode related issues, because I've tried to set it not to sleep

shroomz... my post was not about having issues coming back from sleep mode. the pc won't even go into sleep mode if SFP is open.

as for disabling things, i know what to disable. this is my job, a pc tech. you go into services.msc to disable the services. i was just wondering if there was a way to get it to sleep with sfp open...

however... the previous explanation makes plenty of sense, about the hardware needing to be reconfigured if it goes to sleep.

guess i will have to just shut my machine down at night...

@ MusicManic: the smilie was exactly expressing the conclusion of Crisis (and me) here above, based on Symbiote's explanation: something to wish but obviously and alas only something to dream of

Ahh, ok, sorry crisis I misread your post, my mistake

As mentioned, this is most likely not possible.

The computer not going to sleep, howerver, IS possible as mentioned, so take your pick

Not sure what's ment with sleep mode, but I do use power saving when I go out to work etc. I removed all Windows presets in the Power options, cos they don't make any sense to me, and made 3 configs: "Always On, Disk Only, and Sleep". Linked a keyb shortcut to Power Options, so Ctl-Alt-P, A would disable all power savings. Ctl-Alt-P, S selects sleep mode. Only trick is to manually wake/spin up the harddisk, since Scope doesn't take its time and crashes if data isn't fed fast enough. Opening a text on each physical disk or emptying the Recycle Bin usually does that. Then Scope can be continued, projects can be loaded without problem etc. Admittedly, if I forget to spin up the disk myself, Scope may take down the OS with it.
