I'm loving this thing, having carried the 2010 MBA for a year. I'm having one issue, however. When I close the lid and put the MBA down, and come back to use it several hours later, it won't wake up today. I open the lid, the screen light comes on (the Apple on the lid turns on), but the screen stays black.

I try clicking the touchpad to wake it up, but eventually I need to hold down the power button to shut off and then restart.

Any ideas?
 
This did occasionally happen with the last generation of MBA's and snow leopard the it will get stuck waking up, often it's a case that the backlight didn't come on. It's been reported here on MacRumors and on Apples support site.

Happened to my 11" 1.4 MBA twice in the time I had it, a forced reboot sorted it each time.

That was an issue early on with the 2010s last year, and appears to have resurfaced. Last year Apple came through with some firmware updates, and I suspect that's what they'll need to do again this year.

Where would I find that file - Spotlight doesn't see it.
Click to expand...

/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist

if that doesn't show up, delete

/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist

as the AutoWake.plist can be saved inside that.
 
I haven't had that issue and I'm on Lion? Odd. I also thought the back Apple logo's brightness came from the screen itself, how can the screen be black and the logo alit? :confused:

And if deleting that doesn't work, delete the sleep image. Go to terminal an type this in


sudo rm /private/var/vm/sleepimage
 
This has happened to me a couple of times with my windows laptop, it turned out it was the screen backlight that didn't come on, I would adjust the brightness with the keyboard and bam the screen would come on and everything would work fine. Not sure if this could be your issue, but try it out next time it happens.

Next time it happens, try closing the lid, waiting about 15 seconds, and then reopening the lid. Worked sometimes for me on my 2010 Macbook Air.

An alternative, which I had to do to my Macbook Air a year or so ago, even after the firmware updates didn't cure my problem, was to disable Safe Sleep. I set hibernatemode to 0. See here:
