Tiny7 - Hybrid Sleep not available

incognico · 10-19-2009, 10:56 PM

As per title, I can't seem to get the hybrid sleep option to appear in my build. VIA MII-12000, Tiny7 rev 1.

"powercfg - a" shows S1, S3, and Hibernate are available, however hybrid sleep is not. No reason is given, it's just listed under modes that are not supported

Sleep and Hibernate both work fine.

Anyone have any thoughts as to why this option is not available, or how I might enable it? Anyone have hybrid sleep working on an MII-12000? Tiny7 rev 1?

Frustrating!

Power Options->Change Plan Settings->change advanced power settings->Sleep->Allow Hybrid Sleep

If its not there...are hibernate and sleep both there? Are they both enabled?

Appreciate the reply unfortuately Hibernate and Sleep are in that "advanced power settings" menu (enabled & working), but Hybrid Sleep is not. I assume because the OS thinks it is not available going by the "powercfg -a" results

I would have thought Hibernate and Sleep were the only prerequisites for Hybrid Sleep...?

Probably because that's one feature that was stripped out of that Tiny Win7 variant.

This is another example of why I recommend AGAINST using the stripped-out Windows variants that someone else creates.
Unless the creator of that variant details every file, service, component and feature that is removed or disabled, you have no clue as to what Windows functionality works and what doesn't.

If you want a lightweight Windows, you really should install a full version and strip it out yourself, either manually or with a tool like nLite/vLite.

I agree with DarquePervert on this one. Install a full version and strip it out yourself.

As far as hybrid sleep goes, I'm using a variant using both sleep and hibernation. I've configure my computer to sleep on power off, so that when I make short stops at gas stations and for coffee it'll wake back up quickly. But I also have it configured to auto-hibernate after sleeping for > 30 minutes (It semi wakes itself back up to hibernate.) Since I'm using an SSD, this prevents the forced memory disk write except for when I'm out of the car for longer than 30 minutes, when I'm likely going to be out for a while.

Hybrid sleep works well if you're worried about either sleep not working, or if you expect your power supply to pull the plug at any time. My Opus PSU automatically kills power when my battery level drops too low, but this doesn't occur within my 30 minute window.

Yeah I supposed there's a good chance that something needed has been stripped out like you say. I'll give it a go with the full version and see if it works. Thanks for the replies guys.

Now that's interesting. I haven't come across this sort of thing before... is this a built-in feature/option? This is what I wanted from Hybrid Sleep, and my only real reason for migrating to Win7.

Yea, it's built in for win7 (probably works for vista and maybe earlier, dunno).

I think this is the right options I have set:
In advanced power options
- Disable hybrid sleep
- Under Power buttons and lid options
---- Power button action set to Sleep. (or whatever action your computer takes when you cut the car off)
- Under sleep options set to never sleep
- Under hibernate options set to hibernate after 30 minutes (or whatever time interval you want it to hibernate in)

I can send some screenshots from my install later this evening

Keep in mind the hibernate interval will still attempt to hibernate your computer while your car is on, if it hasn't received any user input after the length specified. I'd set it to a long enough duration that you know your cars battery can easily handle. My car can easily do an hour in sleep mode (haven't tried anything longer than that.) but 30 minutes seems to work well enough for me.

looooool
This is not what hibryd sleep do. When you set hibernate after 30min then if you not move mouse 30min pc will go to hibernate. So if you drive 30min without pressing anything on touchscreen it will automatic go to hibernate...

Yes Dejan, I have explained this in my post above as well. I hardly ever leave my computer screen un-touched within 30 minutes, which is why I choose the 30 minute interval. But I could have easily chosen the 1 hour interval.

But what this approach does benefit from is allowing the user to quickly sleep the computer without having to write memory to the hibernate file every time while still allowing the computer to enter hibernation mode when I leave the car for longer than 30 minutes. The hybrid sleep ALWAYS writes to your hibernate file, even if you're just leaving it off for a few minutes, which isn't very valuable for my setup and usage.

Yes this is true and for a lot of users is this good solution BUT you can easy lose your data. Why?
Example:
You put your PC in sleep and you have setup your PCU that cut off power if voltage go bellow 11.5V. When you are turn it off you have 11.6V and after 10min fall under 11.5V and PSU cut off power. When you came back windows start normaly booting but cuting off power can defect some files and make error on booting or something else...
With hibryd sleep this can't be happened... I hope that you understand what I would like to tell... But your solution is good for someone which motherboard do not support hibryd sleep or someone who don't want use it...

make sure you have the proper graphic driver before attempting anything hibernation related.

nobb · 10-21-2009, 03:08 PM

Out of curiousity, how well does Tiny7 run on your VIA MII-12000? I dont think that motherboard is enough to run a full version of Win7 (although I may be wrong) so Tiny7 is probably your only choice. Sucks to hear that Tiny7 doesnt support hybrid sleep.

Punky · 10-21-2009, 03:11 PM

i'm pretty sure someone else on here got s3 sleep to work on tiny7, there was a thread about it a while ago.

Very good point, and I agree it's highly worth considering before using this method. The SSD drive I have eliminates this threat since it contains a backup capacitor for flushing cache to disk on power failure. Unsaved documents in memory will of course be lost, but that's another topic. If you do not have an SSD, you can disable cache and eliminate the threat similarly.

However, the probability of dropping below cut-off voltage within 30 minutes of sleep is far lower than within lets say an hour or two. The risk is very low, and the benefit is worth the time it takes to sleep as well as prolonged life of the SSD in my opinion.

Ah yes that's a small downside to this method. *thinks out loud* I could just have my custom HID keyboard emulator (wireless receiver for steering wheel buttons) send a non-function-assigned keypress every 15 minutes or so I guess. Not that it's likely to go for any length of time without interaction, like you say.

Thanks for the info - I will give this method a try. One question - does your power supply draw any more current when the PC switches off, compared to having the PS shut itself off completely? I suspect mine would, although I'll have to put the meter on it and check.

And that's just why we're discussing it

The VIA MoBo seems to run Win7 fine

I'm not sure if it is Tiny7, or just my setup that is preventing Hybrid Sleep from being available. I will try a full install again and see if it becomes available.

Yeah S3 sleep worked fine for me - it just needed the VIA video drivers. It's the Hybrid Sleep option that is missing
