Thread: Tiny7 - Hybrid Sleep not available

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.

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

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...

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

Or you could just set your power supply to shutdown after 30mins...use hybrid sleep...and avoid all the hassle.

Now back on topic.....
Go into your BIOS and ensure S3 is the default sleep state. Quite a few motherboards ship with S1 being the default.

Not sure what you mean. My PC switches off with my car stereo, and when it cuts off it still draws current, but very little. I haven't measured it, but obviously enough to keep my computer in sleep mode. After the 30 minutes when it enters hibernation, it still draws current as well, but far less than when sleeping. It's at least enough to power the LEDs on my keyboard. The PC is completely off, but whatever residual power that goes to the keyboard lights is still there. When the PS shuts itself off completely I'm pretty sure it kills all remaining current, although I'm not 100% certain of that. I've run my system for about 3 months now. The longest I've left the car off is about 36 hours.

Well that was the original plan, obviously requiring that I get Hybrid Sleep enabled.
Changing the settings in the BIOS causes the "powercrfg -a" to report that different modes are supported - none of the settings enable Hybrid Sleep though

I will try the full install and if that doesn't enable the option, I will run with eigenVector's solution. I'll report back the results with the full install anway.

Yeah that's what I was talking about. From an ideal design point of view that's why I'd prefer to try and get the Hybrid Sleep option working first. Thanks for sharing your setup by the way

I'll clear some things up/set some things straight:
1. When in s3 suspend mode-the power supply is providing power to the 5v-standby rail only. This power is consumed by the system clock, network cards with WOL enabled, non-usb keyboards and the ram. Current draw is somewhere between 30mA-1A depending on your ram but in most cases ~30mA for a single stick ~50mA for 2 sticks plus accessories.
2. When in the s4 (hibernate) or s5(soft-off) power state, the system powers the same devices as s3 except for the ram. Typical current draw in this state is ~5mA.
3. When resuming from standby/hibernate or going to standby/hibernate the system will typically use close to its max current draw (the most current it will draw when operating) due to the high cpu use, disk spinup and usb device initialization. These numbers are very system specific but are usually in the 3A-20A range depending on if its a ulv processor or a full desktop CPU.

Yes you are true, but if you set for example 2hours or 3 hours this can happen...
Im not try your solution but I have one question. What happen after 30min? It turn on pc from sleep and then go to hibernate? Does turn on screen too?

@incognico: Are you shure that your motherboard support hibryd sleep? Which motherboard do you use? If I remember my previous MB Via NX15000G doesn't have it so I think that problem is not in Tiny7 but in your PC... Can someone confirm that work Hibryd sleep in tiny7???
