    Hey guys. I just switched to a MBA 11" and noticed that if i have the lid closed for anything over about 30 minutes that it takes a lot longer to wake then my '08 black MacBook. I was told this is because it goes into a deeper sleep then traditional macbooks.

    Is there anyway to make this MBA wake as promptly as my old macbook?

    Splash some water in it's eyes, that'll do the job :p .
    Nah, try searching the forums for a similar problem, you can usually find solutions somewhere around here, or possibly the Apple site.

    The reason it wakes slower than your old MacBook after an hour is because it enters what Apple calls "Deep Sleep".

    This is what allows the MacBook Air to be put to sleep at 7 PM at night, and be woken back up at 10 AM the next morning only to have lost 1% of battery life. This is also what allows that MacBook Air to be put to sleep for 30 DAYS and still have battery life when it's woken back up 30 days later.

    Also, if you do not already know this, it only enters this mode when it is put to sleep and left unplugged from a power source for an hour. If it is put to sleep and you leave it plugged into a power source, it will not enter "Deep Sleep" and it will wake up pretty much instantly as it normally does.

    But, to answer your question, if you want to disable "Deep Sleep" so that your MacBook Air wakes up from sleep "like your old MacBook," try typing in the following code in Terminal:

    sudo pmset -a hibernatemode 0
    Entering that line of code should disable "Deep Sleep" mode.

    To re-enable "Deep Sleep" mode, just type the following line of code into Terminal:

    sudo pmset -a hibernatemode 1
    Hope this helps! :)

    Please post back with your results.

    My 13 MBA refurb does this even when I leave it plugged into the charger overnight or for an extended period.

    Thanks for the tip, I will give it a try.

    I'm not going to agree or disagree with the above, since I know nothing about MacBook Airs.

    Apple made a massive way to the way their laptops sleep around 5 years ago, so I made this .txt file that explained the changes made several years ago. I don't know if things have changed again, but you can easily switch between sleep modes. ;)

    Old PowerBook and iBook sleep mode = 0

    To change to this sleep mode, command (in Terminal): sudo pmset -a hibernatemode 0

    (hibernatemode 0 is the one I use) ;)

    The state of the computer's OS and all software is stored in your RAM when you're using the computer (i.e. Computing 101), and this is the way it remains when in Sleep Mode. Your computer just goes black, but the RAM is kept alive and running. Putting your laptop to sleep is fast, and so is waking from sleep. Unfortunately, if the laptop is asleep for too long and it runs out of power, you will lose all running apps, documents you were working on and didn't save, the song you were listening to on iTunes, etc. This is because the RAM is cleared when there's no power. The next time you connect your AC adapter to your laptop, you'll need to boot-up again. ;)

    MB and MBP "Safe Sleep" mode = 3

    Command (in Terminal): sudo pmset -a hibernatemode 3

    When you put your computer to sleep, your RAM is powered and kept running, so all your running apps and current computer settings are still in your RAM (just like the method I described above), but its also copied to your HDD/SSD so that if you run out of battery power, the previous state of your laptop is still on your HDD. Of course, the data stored on the RAM is gone since there's no power. Waking up from sleep is fast, but putting your computer to sleep is slow because things need to be saved to the HDD first. When going to sleep, look at how much more time it takes for the blinking light to start pulsating. If you run out of power, then the next time you plug in the AC adapter, the state of my computer is restored.

    Sleep Mode = 1
    Command (in Terminal): sudo pmset -a hibernatemode 1

    In this mode, the system ONLY copies your system's state to the HDD, not RAM. Your system's state is moved from RAM to your HDD, and everything on your RAM is wiped. Actually, it's just not powered while your computer is in Sleep mode. While your computer is asleep, RAM is not being powered (which is the case in Safe Sleep (mode 3, above). Of course, waking up from sleep is going to be slow, as is putting your computer to sleep. But if you want to save power, this is the best way to do it.
