macbook air with lion not waking up from sleep

Have you tried taking it in? Perhaps it is a hardware issue. I haven't noticed at all through several versions of Lion. My sister had the issue in 10.7.1 but it has been gone since 10.7.2. We both have the LG screen and Samsung SSD. I have the i7 and she has the i5 (11" model). I believe most of the other parts are the same in the MacBook Air.

As for the hype, it is overblown, but in general Apple customer support is pretty good. That's part of the reason for the hype. The thing to keep in mind is that the same factories make Macs as well as PCs. Apple tends to use nicer screens, cases, trackpads, etc. but the other parts are the same across all manufacturers. It's no surprise, then, that failure rates are similar between all the major manufacturers.

Thanks, I agree that Apple Support is good - when you finally get there and can pin a Genius down (their appointments are in 15 minute chunks and during that time there are numerous distractions)!

I took my then new AIR down and they replaced the graphics board? card? But that didn't work.

So it does seem like a software related issue.

No, the macbook air (i5) model is slow to wake up still - average 5-9 seconds. The Macbook air cor2 duo on the other hand has never had this slow to wake issue. Don't know what it is.

Hey Fei, the snake issue is completely unrelated to the original discussion. Its a bit derailing. I am sorry your "snake" issue has not been solved but its a different issue to the slow to wake up issue that is the title of this thread.

Going in for same scrambled screen problem this morning. Using an external monitor, but when this happens, nothing even shows on the external monitor, only the MBP own screen is scrambled. Like to work with the lid closed. But, when it goes to sleep, I never know if it will actually wake up or I have power off and power on again. MBP performs fine otherwise, but this wake up issue is very annoying.

me too.

can take an age for the screen to come on, even after tapping of keys and swirl and click on trackpad.

or

the screen comes on reasonably quickly yet keyboard and trackpad dont respond for a while more.

MBA 2012 13" i7 8GB RAM 512 SSD 10.7.4 (11E2705)

This seems to be getting worse, and not only when the password is correct, but it takes some 5-15 secs when the password is entered incorrectly. My iMac at home with a spinning drive is near instanteous, but my MacBook Air is much too slow.

Apple, any encouraging thoughts?

MBA 10.7.4 4GB, 1.7 GHz Intel Core i5, connected to a corporate network and with much too much Microsoft software.

You might try resetting the SMC and PRAM. In any case, I have the 2012 MacBook Air and it is back to what it was with the 2010. I believe some of Mountain Lion's new features will require a firmware update (e.g. Power Sleep) so hopefully it resolves the issue with the 2011s.

I have the same problem. Goes to sleep, when i try to wake it up the screen remains black. Sometimes it comes back after a minute or so after smashing random keys or closing/opening the lid. I'm using an external monitor (Thunderbolt -> DVI). If not, i have to hold the power button to force it to turn off and restart.

I was wondering whether the problem had something to do with the fact that when my Macbook goes to sleep the external monitor is connected, i then remove the thunderbolt cable, go out, and later wake it up - when the external monitor is nolonger connected. But probably not.. after reading the replies above.

SOLUTION THAT WORKED FOR ME:

I was suffering the same 5-10 wake that was mentioned in this thread. This is the solution that worked for me. My wake times are now less than a second or two.

Problem: Launch agents for Flash & Apple Remote were causing the delay.

Solution: Disable those launch agents.

WARNING - Do not disable launch agents if you do not know what they are responsible for.

I use the free tool Lingon 1.2 to edit my launch agents. There is a newer version of Lingon in the appstore for $2.99 as of this writing. I am not associated with the developer.

(1) After launching, I clicked the "User Daemons" tab.

(2) I disabled remote sync agent

(3) I disabeld adobe flash update agent

(4) Log out & Log back in.

I hope that this solution helps someone else.

fyi, I noticed these error logs in Console when this problem occurs:

21-7-12 3:39:05.496 PM loginwindow: Attempt to focus on invalid point {720, 439}

21-7-12 3:40:17.488 PM loginwindow: _NXGetScreenRect: error getting display bounds (1001)

The login window is activated and loging in is possible, even though the login window is not visible and the screen is black.

After I enter my password and hit enter (while the screen is black), the screen is normal again and i see my desktop...

This might be it. I have now the 2012 MBA I7 8GB RAM. Still it is not as rapid wake i had on my MB pro before lion, but it is faster than my 2011 I7 4 GB RAM.

I have now installed almost every program that i had on my previous MBA (didnt recover this time) I have not yet installed the flash player (dont think i even will.. Who other than **** sites uses flash anyway?)

Without flash player the wake takes about 1,5 sec. not 4-5 sec on my previous MBA.

Maybe i take a time machine copy and install flash to see if the slow wake comes back, but i dont know if i find the time to do it.

I hate the slow wake. The instant wake was one of the coolest things about osx..

Wonder why apple has not given a reply on this..

(by the way... When using external screens the slow wake is still a problem,)

I don't know if anyone has mentioned it yet, but I was able to solve this problem for my case:

Problem was wrong hibernatemode. Check the man-page for pmset for details or look here:

https://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages /man1/pmset.1.html

Open a terminal and check with:

pmset -g | grep hibernatemode

This should usually give back: hibernatemode 3. If this is not case - I had hibernatemode 25 - then here is your solution:

sudo pmset -a hibernatemode 3

This sets hibernationmode back to 3 for AC and batterymode, which means: If you close the lid, your Macbook keeps everything in RAM instead dumping a RAM-image to the SSD. If you open the lid, all is there instantly instead to read the image from the drive - which takes around 8 seconds with 4 GB of RAM like in my case.

hth

No, I have this problem so i tried that just like you said, and it told me my hibernatemode is 3. I've had this problem now since december, I'm going back to the apple store next week while it's still under warrenty!

Thanks. But I actually think the default hibernate mode makes sense, and I wouldn't want to change it: if the computer is asleep long enough (overnight, typically) then I accept the delay (and the benefit) of having RAM written and read from SSD at the next wake.

But the problem here is that this delay occurs EVERY time, even if you sleep the Air for a SHORT time... seconds, even.

If the delay is a matter of RAM being dumped to SSD, then it's happening instantly when it should not. A serious bug, if that's the case, but one which your workaround could indeed help with. (At the expense of giving up the benefits of true hibernate, which would be a shame.)
