    Very interesting observations Intersnake.
    Read this? http://discussions.apple.com/thread.jspa?threadID=2655095&tstart=0 and this? http://support.apple.com/kb/HT4392.
    I bought a MacBook Air 11.6" for my wife two weeks ago, she loved it... until yesterday. Go to sleep while in use (battery depleted), connected to the power source, pressed the Power button and... no can do. Simply can't get it to turn on again, tried ctrl-shift-power, resetting the SMD, nothing worked. She told me the machine was behaving strangely before: not waking from a closed lid as fast as before, draining the battery even when on sleep, and the like. Did my home work too and it looks that 1. there is an error in the original setup as you suggest and the hibernatemode is set to 3 and not 25 (no way I can check it now) 2. there is a hardware issue (please not!) 3. some problem related to (don't laugh!) Adobe Flash... My son installed it on the Air some 10 days ago. Thinking about it, there must be a reason to this machine shipping without it, don't you agree.
    Anyway, since I can not boot my wife's shinny, expensive new MacBook Air, looks like things can get very ugly since I'll need to contact phone support down here (in Brazil...). Sighs....

    Correction, that (setting startup disk) didn't totally work. Worked for about a week, but then wouldn't wake. I'm still going with disabling hibernate mode.

    I've had the problem, too, intermittently. It's just started happening. Doesn't seem to matter whether my battery is depleted or whether the power cord is connected. It is a little disconcerting. I love this otherwise.
  • jamiana Level 1 Level 1 (10 points)
    I know. I loved my little macAir. The latest os10 update did not fix it. As a matter of fact, it is wreaking strange havoc on my mbpro's. Waking up from sleep to find all the browsers and programs I had open that i was working on closed. Don't know if it is rebooting itself in sleep.

    And the latest safari update has the browser crashing all day long.

    I am now on my third new 11" MBA after experiencing this "not waking from sleep" problem with my two previous MBAs. I am now trying Intersnake's solution and am hopeful it works. I love the MBA but it's been more of a nuisance with all these problems. I have had multiple contacts with Apple Tech support and even had an engineer-type tech call me to discuss my problems. The local Apple Store genius bar folks don't admit they are seeing this problem on a regular basis but I suspect they would not tell me if they did....

    After a couple of weeks with hibernation still disabled, I haven't had any problems waking from sleep.

    I find it hard to believe that even with a fast SSD, a Mac with 4GBs or RAM could resume from hibernation in 5 seconds which is how long it took before I disabled it and after letting it sleep overnight. Also, if it truly was hibernating, which means completely powered down, a fully charged battery would last much longer than one month in that state. I found that with hibernation turned off, I would lose 1% of charge per 7 hours of sleep which puts it square in apple's estimates for standby time.

    I KNOW. I hope they get the issues resolved before they sell a ton of them for the holidays.

    i am joining the dark screen, not even backlight on, hard reboot required party. happens about 1/4 of times, no matter how long the 11" air sleeps. or let's say, most of the time it seems to happen after longer (couple of hours) sleeps, but i've seen it happen with lid not even closed, after returning from getting a coffee.
    since the machine works flawlessly otherwise and more and more people are gathering here, this must be a widespread thing, most likely due to software or firmware issues.

    ok, my real contribution: selected the hard disk as default boot disk (as suggested above) AND disabled hibernation (mode 0). seemed to improve. but then: bang! just ran into a black screen of death again, after a sleep of approximately 5 hours.

    come on, apple! get down to work and fix this!
  • FredericMoreau Level 1 Level 1 (0 points)
    Edit: Since some people have suggested adobe flash could actually be causing the problem, I uninstalled it, replacing it—so as to keep at least youtube—with the safari extension youtube5 (http://www.verticalforest.com/youtube5-extension/).

    let's see how that goes!
  • hiro-reason Level 1 Level 1 (60 points)
    Wow! You're the first case I've heard of with this happening with the hibernate mode disabled. I'd go for warranty. Make 'em give you another one.
  • FredericMoreau Level 1 Level 1 (0 points)
    i am not so optimistic about disabling hibernation solving the issue; if i am the first case you have heard about (and so have i), does this mean my unit is more defective than others?
    it seems more likely to me that hardly anybody tried it out long enough AND responded back here.
    these things have been out only for a short time and many people are not such power users as probably most people on this forum. i would actually be surprised if others could not reproduce the problem with hibernation disabled (mode 0).
    just try, as a first test, to hibernate the computer with safari loaded with flash content open. don't rejoice if it comes back alive once. an extended test would be necessary. (of course this is just one possibility).

    but again: as everything else works like a charm, i very much doubt that the unit is actually broken. i am still having my hopes up that apple will fix this with an update.
  • hiro-reason Level 1 Level 1 (60 points)
    I'm only suggesting getting another one out of despair of figuring out the problem. I thought we had it with the hibernate mode. Since most people don't have the problem, odds are that all of us do have something wrong with our machines. Or at least it seems that way to me.
  • FredericMoreau Level 1 Level 1 (0 points)
    again, i am not so sure that we're rare unfortunate cases. have you seen this passage from a recent ars technica review?

    QUOTE
    Finally, we have to note that we experienced two kernel panics during our battery testing. In both cases, it appears as if the kernel panic was triggered by putting the machine into standby mode when the battery was close to running out. Both times the machine appeared unresponsive after opening, and the display wouldn't come on. Pressing the power button to boot the machine didn't work; instead, we had to hold down the power button to power the machine off first, and then power it back on (this is a case where some sort of independent battery indicator would have helped figure out what was happening).

    We discussed the issue with Apple, and provided them with crash logs, though at press time the company was unable to determine the exact cause of the problem. To our knowledge, no other reviewers have noted similar issues, and Apple said that our report was the first to detail such a problem. However, Cult of Mac noted over the weekend that at least one staffer has experienced kernel panics with a new MacBook Air.

    of course i have no statistics, but my gut feeling tells me there is something pervasive going on here. also, some people writing above AWARE OF THE PROBLEM returned their unit ONLY TO ENCOUNTER THE ISSUE AGAIN. in one case i've read about even three times in a row. this stinks!

    it reminds me of the faint grey lines on previous generation macbook air displays. most people did not complain about them, did not even see them. but they were definitely there, you just had to be perfectionist enough. i examined many models and actually never saw one without them. would've bought it otherwise.
    granted, the present issue is not something debatable (but then the lines weren't really either) because it's just and undeniably there. anyway, i am actually pretty optimistic that a solution will be found. (whereas with the lines, i was very skeptical; it seemed too much of a hardware issue to me. here, as i said, i think software or firmware updates will fix it.)
  • hiro-reason Level 1 Level 1 (60 points)
    Hmmm. I dont see the lines on my first gen air.

    As for the low power sleep, I've seen that with regular macbooks. Once, my wife ran hers down and tried to wake it unolugged, and it died during bootstrap. Taking out batteries didn't work, no key cimbination, nothing. Finally, I took out the ram to force it to start over. After replacing it, it came up fine. Never let your air do that, or you'll need a soldering iron.

    As for our south american friend earlier in the thread, i suspect thats where he is. Gonna have to ship that puppy back. I really am leery of the "run it to failure to teach the battery management how the battery behaves" advice. Particularly with this no user serviceable parts design.

    I have a sony vaio with a solid state drive, and I have not had much luck hibernating it, either. But, running windows, it is too slow to test like i do this one. The new airs are quite snappy, unless you get the grey screen of panic and dissarray, or the black screen of despair.
