    Help with Windows 7 power settings

    So I've been trying to configure my software for days now and I've run into a few problems. One of which having to do with the power settings in Windows 7.

    I would like to set it up so that when I turn off my car (hit the power button) it will go to sleep. So far, I think it does that OK. I run into the problem because after a certain amount of time (~30 minutes) being asleep, I would like it to go into hibernation.

    Ive been playing with the power settings and for the most part have not even been able to save the settings I put in (they would appear to save, but next time I go into the power settings, they would be default settings again).

    I finally got it to actually save and I set the power button to make it go to sleep, and for it to go into hibernation in 5 minutes (for testing purposes). So I pressed the power button and it went to sleep no problem. Then I let it sit for 15 minutes and nothing happened (it didn't go into hibernate mode). Then when I pressed the power button to wake it back up, nothing happened again!

    Assistance please. I am at a loss.

    Laptop? Desktop? PSU?
    As far as i know this only works with laptop or a desktop with constant power.
    I'll provide more help as you post more information.

    when you edit advanced power options you should enable hybrid sleep. set your power button to initiate sleep. In that case you don't need to worry about hibernation. What will happen is that the computer will go to sleep, but also set the hibernation state. If your PSU loses power, and you restart, it will resume from hibernation. Instead, if your PSU is still powering the PC it will resume from sleep.

    hybrid sleep doesnt sound like what I want. I want it to sleep when I shut the ignition off and hibernate some amount of time after it goes to sleep. from what I'm ghetting fromk your post, hybrid sleep will just send it into hibernation when I turn off the ignition.

    no, hybrid sleep is a combination. here's how it works in my carpc:

    1. PC running, I turn ignition off
    2. PC goes to "sleep" but it also generates a hibernation file.
    3. PC remains in sleep for 30 minutes until the PSU kills all power to the PC
    4.1. I turn ignition on AFTER 30 minutes then the PC resumes from hibernation
    4.2. I turn ignition on BEFORE 30 minutes then the PC resumes from sleep

    Alright I looked up hybrid sleep mode and after doing some reading I decided that it will do what I wanted. But now I'm having trouble finding where to enable hybrid sleep mode.

    Where is it?

    Thanks

    if you're using an automotive PSU then it should have a built-in or programmable hard-off timeout. They also tend to have low-voltage cut offs (i.e. your battery dips below a certain voltage and it cuts power).
