i'm currently using hybrid sleep on my carpc, and I have to say to people who are skeptical.
it is 100% reliable, no issue whatsoever it is as reliable hibernation except 100x faster.
impressive advance usb programming feature by the way! definitely will play with this one sometime in the near future.
please try the usb programming and let us know how well it works driver/stability stuff!
interesting. i tried it wasnt as reliable for me. as a matter of fact it would cold boot half of the times with hybrid sleep. may-b i did something wrong in my setup, and please correct me if i did; turn hybrid-sleep on, set windows to sleep on power button press. at this point the pc should sleep when the power button is pressed and wake up when it is pressed again, if the power to the pc is cut, the pc will resume from hibernate at next powerup, correct ?Quote:

if hybrid sleep is setup correctly, computer should wake up instantly with power switch button pressed.
a few things i can think of that might be set improperly. Did you check if your power option has hybrid sleep enabled? if not then you need the proper graphic driver install. Secondly, your motherboard must support S3 sleep, s1 sleep will work as well, but theres a ton of things running when you're using hybrid sleep, which drain you battery much faster. Finally your power supply must keep the 5v rail on after ignition has been turn off.
@sergatiuk:Great write up! I was just looking at this device over at mini-box's site and decided to do some research on it and stumbled on your article.
I have a few quick questions, or rather a request to farther test the device.
When the device is operating in "UPS" mode, and when plugged in, via USB, to the host computer, does Windows recognize it as a UPS device? For example, if the power is cut, will Windows recognize that it is now running on battery power?
Mainly I'm curious if the device will play well with the Win32_Battery and Win32_PortableBattery Windows Management Instrumentation classes.
If so, this could open up a whole bunch of fun programming ideas.
Example: (theoretically) one could rig the device up to the car's battery as the "battery" and Windows could tell the power % and life expectancy of the car's battery.
Thanks!

i like where you are going with this thought, and it is a hard question for me to answer, however as far as i understand on USB the device will simply be recognized as a programmable power supply. and even in UPS mode the device will still output the same voltage, no matter how low the battery gets, even when the battery will reach 7VDC this device will still output whatever it is set to, unlike the laptop battery which slowly drains and drops voltage until its too low to power the computer.Quote:

in my opinion 7 would take the most advantage of this device's features simply because of the hybrid sleep option. you could pretty much set the device to hibernate and cut power when the car battery reaches a certain level, which would work similar to the way laptop batteries do, they sleep, hibernate or shutdown the lappy when the battery reached a certain predefined level. the only difference is that in the lappy it is done by the OS and with this device this operation is performed by the unit itself.
i hope i make sense....(;
Very interesting. You answered my question perfectly.
As far as the product goes, I guess I was hoping it would provide a more diagnostic approach, with seamless integration with M$.
...I know, "seamless" and "Microsoft" in the same sentence? A boy can dream, right? :p
Kinda like the APC's UPSs. From a software standpoint, those UPSs "function" just like a laptop battery.
I think, this device is pretty cool, and has tons of potential. However, personally, I would like to see the UPS option behave more like a traditional UPS. (i.e. Tell me if I'm "plugged in" and how much battery power I have left without having to install special software.)
Heck, with a device that does that, you'd be entering the world of DIY UMPCs. Now that would be cool! Rig up a Pico-ITX mobo, slap a screen and a battery on it, and bam! Your "carputer" is now a "CarDA" - thats a play on the acronym PDA if you didn't get that. ...ok, so maybe that name is kinda awful, but you get the idea. :lol:

a fair outlook of the very near DIY computing future.
to a certain extent that future is already here.
as far as i know - and i might be wrong, lappy and netbooks mobos have additional components that make them compatible with batteries besides the software itself, these batteries arent USB so the mobo needs to be able to read the battery voltage and health. technically if u grab a mobo from any netbook or lappy connect a touchscreen to it and you got yourself an UMPC or a tablet ...get your hands on one of those secret 6months-lasting fuel cells and you dont even need a PSU (o;'
The UPS mode doesn't show up as a UPS, although it's a HID device so theoretically a driver could be written for it but it's not needed. It looks like you can set a voltage threshold that will tell it when to shutdown instead of startup/shutdown when IGN goes on/off. There's an optional voltage level for IGN on, another for IGN off as well, so it can just leave the PC on as long as the battery is above the specified level.
Oh and there is a timed anti-thump aux output.
yeah this would have been so much better then trying to do it myself with that auto-shutdown controller. i still dont even have that working, but not because its hard; i havent had time. i spent $60 on parts, and even though i could make like 10 shutdown controllers, if i just bought this device i would actually have a working fail-safe system by now. i really like the flexibility of this gadget
Two questions:
1. With the DC-DC power supply, how are you getting that power to the motherboard? I assume you soldered it to the motherboard at the DC port (red/black wires).
2. I am considering, instead of using the Zotac board, to instead purchase an Acer Revo nettop. Its power supply also runs at 19volts. If I want to power a lilliput monitor, can I connect a voltage regulator (step down/7812) to the 19volts coming out of the dc-dc power supply?
Thanks!
