  • Mimic mac's Safesleep on pc??

    On a mac laptop, if you close the lid, the computer goes to sleep.

    If your battery runs dead or your battery is removed while the computer is asleep... plug it in/put the battery back in, turn it on.. and what do you know.. you're still back to where you were when you put the computer to sleep...

    How it does this...?

    Right as you close the lid, it writes an image of the RAM to the hard drive and then goes to sleep. If power is cut, battery runs dead, etc (ram cleared)... the next time the computer is woken up, the computer boots from scratch but sees that there is a ram image on the hard drive, it loads that ram image from the hard drive back to the ram and resumes what you were doing, takes seconds. This might seem similar to hibernation like most PC's can do, yes.. it is, except that the mac uses a hybrid style of sleep. It doesn't resume from hibernation if it doesn't have to, only if it NEEDS to (if power was lost completely and ram was cleared).

    In the car pc world... some of us don't love the time it takes for hibernation and resuming takes and sound of the sound card turning on, off, etc.. durring that resume.

    I have always had my carpc just go to standby (sleep) and resume and power is cut from the computer (always laptop based) and the laptop's battery holds the data in the ram until the next time I drive the vehicle, this has worked okay, but for the fact that the acer aspire one in my truck doesn't hold a charge for more than two days.. it bothers me because the computer then has to boot from scratch ..

    is there a way to mod the bios, windows, etc... to allow a similar sleep state as apple's safesleep ?.. it'd make things so much better in my opinion.

    any input is appreciated ..

    See hybrid sleep in Vista and Win7. Been using it for a while now, works just as you described.

      Leave it to apple to take a standardized technology and give it a proprietary name as if they invented it

        In their defense, I'd be shocked if Microsoft hasn't a copyright on the term :P

        On a side note Linux is also capable of this, albeit after a good amount of tinkering as it does not come stock in any distro I can think of. It's an awesome concept, and I'm glad the big three OS flavours take advantage of it.

          Its referred to as hybrid sleep on Linux too...that the only reason I was complaining that apple had to be "special"....normally I just keep my annoyance with apple to myself lol

          but yea I think the latest Ubuntu (not yet released) has it but the distros certainly lagged behind on implementation.

            Yeah, os/x and linux has been doing this forever, it's super clever and its great to see microsoft catching on to these little ideas 23948 years later with these "new features" in vista/7, still way far behind (i'm a deep multi-OS user)

            Okay, thanks for the input though, now as I remember, I do think I remember reading about win7 having that power state ability, I hope it's not reliant on certain motherboards with EFI or built in power manager states, we'll see though, I'll get experimenting.

            Maybe I oughta get upgrading to win7 then on my vehicle's Pc I suppose.. blarggh..

              Released as hybrid sleep in vista in august 2005...added to the linux dev branch shortly after as hybrid suspend....released by apple as "safe sleep" in october 2005. Damn Microsoft and their time traveling theft

              For any OS, your motherboard will need to support the S3 sleep state. As long as that is supported and enabled on your motherboard, then it will work out of the box on your os of choice.

                Apple is so unappreciated. Amazon totally ripped them off with this kindle "eBook" crap too, obvious take on iBook!! did you know Steve Jobs invented innovation???
