Lion apps do not wake from sleep

Several times after may 2008 Macbook using OS X Lion, it struggles to recover from sleep. When it finally revives, all apps that were open are now closed. What could possibly be the problem?

That's interesting, I don't use the Apple->Sleep, but I tired it several times with 10.8.1 on my system and it woke up in a timely fashion.
There is something strange going on with it being intermittent for me, a combo of always & intermittent for you.
I suspect there is some combination of circumstances that's not obvious that's causing it.
I've looked through the logs and don't see any clues.
I submitted a bug report some time back.
You might consider submitting one as your situation is a little different and you have a circumstance that always causes the problem.

With Mountain Lion MacPro does not wake from sleep

I have installed Mountain Lion (10.8.1) on a Mac Pro (Model appeared early 2008).
However when the system is sleeping, Mac does not awake from sleep by pressing any key of the keyboard.
The keyboard is inactive.

TS4080 apple thunderbolt display image on display intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys. Rebooting by pressing the power button resolves issue.

My apple thunderbolt display (which I purchased 1.5 years ago; OS 10.7.5 Mac Mini) intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys, so am thinking it is a hardware problem with the display. Rebooting by pressing the power button turns the screen back on, but the same phenomenon has occurred several times. Could this be a software issue, or do I need to have my display repaired? Your feedback would be appreciated.

Hi ED, tough to tell, but it does sound like it's waking with the bonk, just not displaying.
Long shot but...
I wonder if it's a variation of this, of which I've seen many different symptoms...
Resolution
Move the mouse or trackpad cursor over the center area of the login window so you can see the user icons. Click on the icon of the user that you would like to login as, type in the user's password, and press Return.
If the login window is configured to show only the name and password fields, type in the user's name and password into the fields, and press Return (even if you cannot see the rest of the login window).
Additional Information
This issue will not occur if the display is not sleeping when the account is logged out. Use the steps below to confirm that the account is not configured to log out automatically while the display is sleeping:
1. Open System Preferences > Security & Privacy > General. Click the padlock to unlock the preference pane and enter your admin password. Click the Advanced button at the bottom, then see if the option "Log out after N minutes of inactivity" (where N is the number of minutes) is enabled.
2. Open System Preferences > Energy Saver and configure Display Sleep to occur after the account is logged out, by dragging the slider to a number of minutes that is greater than N was set to in the previous step.
Important: If automatic log out is not needed, disable "Log out after Nminutes of inactivity" in System Preferences > Security & Privacy > General. This will also prevent the issue.

IPhone 1.1.4 will not wake from sleep mode

Hi all,
I have an iPhone with 1.1.4 firmware. The problem that I have is that the phone will not wake from sleep mode by pressing the "home" button. I have to press both the "home" and "sleep/power" buttons and hold them for 6 seconds for the phone to restart. I did restore the phone twice - did not solve the problem. Then, one day, I left it charging for about 3 days and when I came back it started working fine. Not for long though( After about a week of normal usage the wake up problem came back. I don't know what to do. I don't think it's the software problem, since I did complete restoration 2 times.
If the phone is connected to a charger or computer - it wakes up fine.
Thanks, Gene K

rimini,
When you've restored the iPhone, have you tried setting it up as a new phone? This would truly eliminate software as a possibility.
If setting it up as a new phone doesn't correct the issue, it's probably time for service: apple.com/support/iphone/service/faq/
Hope this helps,

IPhone will not wake from sleep and locks up with new MMS update

Hey everyone,
Has anyone had these problems with their new update as well?
1) Sometimes my iPhone will not wake from sleep mode, I have to hold down both buttons for it to restart...I do this about 5 times a day!
2) I cannot send SMS messages and when I send more than one sometimes the iPhone locks up and will not unfreeze.
Does anyone know if this is an Apple update issue or if it is an AT&T issue? And if this is being addressed?
Apple, if you read this could there be an update to all members what is going on?

I am experiencing the same issue with iPhone 3GS. After yesterday update to 3.1.2, it is a bit better in the sense that I can restart the iPhone slightly faster but still getting frozen screen during a call. I will try to call support once more. I don't believe that the problem is solved in the new update.

HP 15t j000 will not wake from sleep/hibernate Windows 8,8.1,10

HP 15t j000 will not wake from sleep/hibernate Windows 8,8.1,10. I have to restart. I've searched high and low for answer to this. I've seen videos, played with power settings. I hoped each Windows system upgrade would fix the problem. No go. Anyone with any ideas?

Hi , Thank you for your query. I understand that after upgrading to Windows 10, it will not wake from sleep mode unless you restart. The first step I would try is to disable "Hybrid Boot' or "Hybrid Shutdown. This can be done by turning off "Fast Startup" Fast Startup - Turn On or Off in Windows 10 Next try running the "Update Troubleshooter" Windows Update troubleshooter. Once launched, it should show a screen like this. Use the second option "Background Intelligent Transfer Service", it should lead to a force update of 'Windows Updates' that may not be automatically being applied, that could fix some of these issues.
Here is a link to HP PCs - Sleep and Hibernate Issues (Windows 10, 8) that may also help. To say thanks for replying please click the thumbs up button below.If this yielded a solution please choose solution provided to help other people find this information. Best of Luck!

MacBook Pro will not wake from sleep

My new 13" MacBook Pro will occasionally refuse to wake from sleep. Touching the keyboard or moving the mouse will turn on the keyboard background lights but the computer will not wake. This occurs without any peripherals attached. I have reset the PRAM and the SMC ... no help.
The only option for recovery is the hard power down with the power button and restart. Anyone else seeing this?

Yes and I hate it. I am having pretty much the same problem, and have tried the same solutions, also Iupgraded to Lion and there still has been no relief. My computer just runs slower.

Apps crashing on wake from sleep

Since upgrading to Snow Leopard on my 2008 unibody Macbook, I've been having wake-from-sleep issues. I'm hoping that someone will be able make sense of the crash logs
Sporadically, when I wake it from sleep, an app will crash, quit unexpectedly. The app will restart fine and run normally after that. It only happens occasionally, twice today, once yesterday, but not for a week before that. The apps involved so far have been Safari 4.03, Mail 4.1, Textedit 1.6, and activity Monitor 10.6, as well as Dashboard client.
The crash log doesn't help me because I don't really know what to look for. I eliminated several of background processes that were mentioned in some of the early crash logs. Permissions repair, disk repair, and Apple Hardware test all negative.
Has anyone else been having problems like this?

I had this problem also, it has been driving me crazy since I upgraded to Snow Leopard in October. I thought that it was maybe the upgrade install type so I wiped the HD and did a clean install but still had the same problem with iTunes, Skype, Google Notifier, Safari and Net News Wire continually crashing after sleep.
Under advice I tried a SMC reset but this did not help either.
Today I called apple care and they suggested a PRAM reset, after a couple of hours testing the problem seems to be fixed.
To do a PRAM reset on a late 2008 MacBook.....
1. Power off the MacBook (shutdown)
2. Unplug mains power lead
3. Count to 10
4. Plug the mains power lead back in
5. Press the power button to start the MacBook
6. Immediately press and hold down the CMD, ALT, P and R keys
7. You will hear the startup chime then the screen will go off (keep holding the keys)
8. You will hear the startup chime again then the screen will go off (keep holding)
9. You will hear the startup chime a third time
10. Now release the keys and let the MacBook startup
11. Hopefully no more crashes after sleep
Hope this works for you

MacBook Pro display sometimes does not wake from sleep, display is blank

My computer has been getting a lot of this weird issue that it is asleep, the light is pulsing. But when you go to wake it up, the keyboard lights up, caps light key will work, but the display is blank, nothing makes it turn back on.
I had a friend using it who I let use the guest account, but since the issue kept happening and all the guest account data kept disappearing, I had to create her an account. It's annoying, and sometimes if I catch the crash happening while the unit is display active, I get the color wheel and all the apps freeze up really bad. I'm lucky if I can save my work.
Sleep during this crash will also produce the error. Most recently I was trying to connect my bluetooth keyboard and it kept giving me an error. So I tried to turn off the bluetooth, no dice. Went into the root user, still no dice. Figured maybe the device didn't get reinitialized upon wake from sleep properly, put the unit to sleep and ding dong, wont wake up again!
From the console logs I've been able to find this string:
5/23/10 1:00:54 PM kernel Sleep failure code 0x00000000 0x21000000
I've not used any hacks or sleep widgets, so I don't know what the issue is.
Everytime I reboot from this I fsck the drive and repair permissions. I've tried zapping the PRAM also, next stop is delete the power management plist and reset the SMC. Who knows if any of it will work?
Anyone have any ideas?

AppleCare is the magic word. Time to contact them.
Btw the machine is 10.6.3 I hadn't updated my settings before I posted the initial question.
I was actually going to suggest that, but noticed in your later posts you had updated the info.
As for the smc and pram both were done today, so we will see what the story is. I also deleted the energy .plist file and had it recreated from within root.
Just curious why you're working in root? You should be able to do anything we've discussed from an admin account, and there's lots of potential for mishaps in root.
As for dlrunning DU, I was under the impression that it just ran fsck through the DU GUI. At least that's what it looks like when you view the console log for DU. I'll give it a try though.
I'm just repeating what Apple suggests.
I'm just worried that the little glitches are adding up to something catastrophic.

Lion, external monitor, and wake from sleep - please help!

For the most part I love Lion. However, the changes they made to the external monitor support are not helpful for me. Let me explain...
I have a 13" 2009 MBP. In my office I use a monitor stand that the laptop can slide into from either the left or the right, and the monitor sits on top. Previously I would simply take my closed MBP in sleep mode, slide it under the stand, and plug everything in. Once the power cord and monitor cable were plugged in, as soon as I inserted something into the USB or SD-Card slot (or I think even the ethernet jack) the laptop would wake from sleep and the monitor would come on.
Now, however, this doesn't happen. My only option is to plug everything in, open the laptop so it wakes up, then close the lid, then slide it into the stand. This is definitely NOT an improvement! Before I had my phone at the left of the monitor stand, and would slide the laptop in from the right. Now, though, I have no choice but to slide it in from the left (after going through the above hassel), which means I had to move the phone off of my desk.
The energy saving preferences have the "wake on network access" box checked, which would make me think that it would wake up as soon as the ethernet cord is plugged in - but no such luck. I also have wireless in the office, but it's hard for it to recognize that when it's in sleep mode.
Has anyone else had this problem? Is there a solution I'm missing here? I'm using a wireless keyboard and wireless mouse, so of course those won't do anything while the computer is asleep.

I'm beginning to hate Lion because of this one problem. It's great that Lion doesn't sleep when you close the laptop with external monitor connected. But I can no longer wake the external monitor with USB mouse movement. I have to open and close the lid. This is very inconvenient when switching between two systems with KVM. The MacBook is awake; it just won't wake the monitor.

PowerBook Will Not Wake from Sleep - Horizontal Lines on Display

I have a new PowerBook that I purchased last December. When my computer goes into sleep mode, it will not wake up unless I do a hard poweroff by holding in the power key for 5 seconds. When it tries to wake from sleep all I see is my mouse cursor on a black screen or the spinning beach ball. I'm also having problems with graphic applications such as Photoshop or Adobe Illustrator where I'm using lines that are only 1 pixel in length. The lines disappear when I drag them across the screen as though I'm missing a whole row of pixels or half of the line is fainter. I also notice very fine horizontal lines throughout my display. My older PowerBook does not have these lines nor this wake from sleep problem.

Contact tech support, it will need to be sent in for repair, and as long as your hardware warranty is good or you have APP the repair will cost nothing. unfortunatly this is basically your only option, unless resetting NVRAM takes care of it. to do that turn off com. hold down option, apple(2 key's left of space bar)and o, f, then turn on while holding those down. when firmware opens up type in reset-nvram, press enter then type in reset-all(include the dash in both)
this will reboot com. if this does not take care of it a repair is needed.

Will not wake from sleep mode

When I close then open the lid on my MacBook, it will not wake up from sleep mode. I have to reboot by holding down the power button for 10 sec. When it restarts, it takes a long time to get past the gray screen with the apple logo. I also have this same problem when it goes into sleep mode, when left idle. I have since changed the settings so it will not go into sleep mode when idle in system preferences. I have reset PRAM and SMC, but the problem still persists.

I have the same problem, intermittently. I think it has something to do with full-screen mode, which I use intermittently. Have you noticed this happening only when you are in a full-screen app?
I also have a MacBook Pro from 2011, and I know for sure my MagSafe power adapter is fine and not part of the problem.
I have noticed a few things that may be hints at what is happening:
one time, (all??) while my screen was basking in the glow of sunlight from the side, I saw that the screen pixels were indeed "on", that the back-light of the screen was just off.
Which led me to the conclusion that my MacBook Pro was indeed waking from sleep, the screen was just not lighting up.
But that theory was disproved this morning, when when waking from sleep, the screen was black, except for my cursor. My cursor was completely visible on a black background. Huh?? It was like some software was putting up a black modal dialog over the whole screen. Also, the Apple Logo on the back of the laptop screen was fully lit -- meaning the backlight was on. The machine was awake (curson moving on a black background), and the screen was fully back-lit.
I'm not sure yet how consistent this behavior is... I will take more careful notes each time this problem happens in the future... But, it looks like I have rogue software that is trying to make my machine look like it is sleeping.
To "capture" the culprit I think I could set up a hot-key command that takes a snapshot of all running processes in Activity Monitor. This could show what processes are running when "waking" from sleep. nabbing the culprit?
I use Snapz Pro. That is non-standard software running with control over screen functions. Maybe Snapz Pro has a problem? I doubt it, but maybe, because it has hooks into background tasks with video. Snapz Pro is my only 32-bit process. Could Snapz Pro be the cause? I use Snapz Pro all the time.
The problem seems to be related to Full-Screen mode. Could it be possible that full-screen apps sometimes have problems returning from sleep? I know there are viewControllers responsible for handling events when waking. Could the symptoms of not waking from sleep be caused by bugs in full-screen apps?

IMac will not wake from sleep after 10.4.8 Update

Recently after a couple of software updates my IMac goes to sleep and the Bluetooth keyboard and mouse will not wake it. The option for wake with Bluetooth is checked. I zapped the PRAM and also checked the HD, Nothing has changed. NOTE: No new software or hardware installs were done except for 10.4.8 update and the other mac software updates. This did not happen in prior versions of the OS on my iMac. Is this a new bug?
iMac G5 1.8 (pre iSight) Mac OS X (10.4.8) Bluetooth, Wake from Sleep

I've been dealing with this same issue, have tried everything, but to no avail. After MANY sessions on the phone with Apple tech support, as well as an Apple product specialist, I was advised to erase my computer and do a fresh install. I did an archive an install, which didn't help, but am not thrilled about the prospect of erasing everything and starting over. This problem started after the August 2006 round of updates. I feel it's bluetooth related, because I used a usb keyboard and mouse for a week as a test, with no problem. The funny thing is, I unchecked "allow bluetooth device to wake computer" thinking it might help, but the bluetooth devices continue to wake the computer anyway (except when it refuses to wake, of course!)
