Screen jitter after long sleep

Hi Folks -
I have macbook air (about 2 years old) running Mac OS X 10.8.3. Lately I'm veen noticing that the LCD screens jitters and jumps when awaking from a long sleep. If I sleep the computer again, and then wake it up immediately, the problem goes away.
Anybody seen anything like that?
Paul

Consider a possible third party software issue.
Consider a visit to the optometrist.

Late 2012 iMac loses resolution after long sleep

Hi guys, 1st time post that I hope someone can help me solve.
After I wake my 27" iMac after a long sleep the text is blurred and when I look at display resolutions I only have two options (1024x768 & 800x600).
A reboot does not always solve it, a NVRAM reset works sometimes and a Safe Boot always works. During NVRAM reset the 1st screen is the normal grey but after the second chime the screen can be snowy.
Currently I have computer sleeps set to never and with the display set to sleep after 20mins, and I have not had a problem yet.
I have reinstalled mavericks (not a clean install), removed memory, disconnected all usb devices and reset SMC but still have same problem.
Anybody got any ideas?
Dave

Welcome to Apple Support Communities ..
Text is blurred .. Safe Boot always works.
Might be a font causing this since Safe Mode disables all third party fonts.
Open FontBook in your Applications folder.
From the FontBook menu bar click File > Restore Standard Fonts
Restart your Mac to test.

Wi Fi looses connection after long sleep and the performs poorly after reconnecting

I am having trouble with the Wi FI dropping after a long sleep. Then after getting back on line trouble with pages loading slowly. This just started when I switched to Road Runner Lightning using a Ubee DVW 3201B modem/router. My service provider is Brighthouse. They suggested that the MAC firewall is the problem. Do I need the firewall with asecure router/ any help appreciated.

I have the same issue and have to cycle the wireless modem on the laptop. Doesn't matter if I'm on a preferred netowrk or no, or if I stay on the same network or move. I come out of sleep, I have to cycle the modem.
It's not life threatening, or anything, but it's a hassle. I didn't have the issue with Snow Leopard.

Lynx k3011w tablet frozen after long sleep under win 8.1

Hi,
I have k3011w tablet updated to win 8.1. Latest drivers installed including intel driver from microsoft update. I found that after long time sleep, the table was frozen. Pressing window key does not wake up the tablet. Short pressing power key does nothing. I have to long press power button to restart the tablet.
Any one has same issue? How to resolve it.
Thanks.

This has also happens to me it is the only problem I have had thus far. I also have the latest drivers. I am hoping a fix will be released. So far, from my research, it appears that there isn't anything much to be done outside of waiting for a fix to be released.
I am unsure whether this fix would come from microsoft or Lenovo, or whether one will come at all.

MacBook Air not reconnecting to wireless after long sleep.

Hello,
First off, apologies if this has been addressed in a previous post; went through a few pages and saw nothing that helped.
I have been having problems with my i5 Thunderbolt 11" MacBook Air - running Lion 10.7.3 - reconnecting to my home network, which is listed as a Prefered Network, after being in sleep mode; especially after a long sleep, say overnight.
I know it's not my network because my 2.8 Core 2 Duo 15" MBP - running 10.6.8 - never has a problems reconnecting.
I see other posts refering to a WiFi Update for other machines, but not the Air. And this was purchased with Lion, so while a re-install might solve the issue - again something I saw suggested - I would rather avoid the hassle.
I've checked with the "Apple people" at Best Buy - the closest thing I have to an Apple Store here in South Texas - and they say the recent update should have fixed the problem.
Thanks in advance for any thoughts/suggestions/advice are greatly appreciated!

There are no solutions because for many it is still an unresolved problem. It is not a problem for most. I for one have three Macs, a MacBook Pro, a MacBook Air, and a MacMini. Only one of the three, the MacBook Pro, has the problem.

Black screen upon wakeup after longer sleep...

In the last 2 months or so, I have seen my MacMini 2011 OSX 10.7.3 crashing withing a minute of wakeup, after sleeps of more than 2-3 hours.
Sometimes the Black screen occurs almost immediately, sometimes it takes up to a minute after the desktop appears (after logging in).
This did not occur until I got 10.7.3 and only within the last 2 months.

Anyone?
I am up to 100 crashes upon wakeup now. Various versions of Lion 10.7.x. I have done clean installs as well.
Does anyone else get the black screen of death shortly after wakeup from sleep?
This never happened on 10.7.0, 10.7.1 or 10.7.2
Crashes happen in both 10.7.3 and now 10.7.4, and for sleeps as short as 90 minutes.

Screen won't wake up after long sleep. HP Envy All-in-one, no touch screen, windows 8

If asleep for a short time (+ or - 30 mins), it wakes up. For a longer time, the computer comes alive, but the screen stays dark blue. If I wait two minutes and then move the mouse or space bar, the screen comes up.
I worked through the on line help, changed several settings, but it did not help.

Help! 2010 imac 27" - Display doesn't work after long sleep

I just recently started having this problem. I've had this iMac since 2010 with zero issues, but it seems like ever since I downloaded Yosemite, the screen won't work after the computer has been sleeping for a while. I have to hold the power button and do a hard restart to get it to work again. If the computer has only been sleeping for a while, it wakes just fine. It's only after it's been sleeping all night and I go to use it agsin. I've checked power connections and all is good. Any ideas??

Hi Punisher8522,
Welcome to the Support Communities! The resource below offers some troubleshooting steps to try when your computer won't wake from sleep.
OS X: When your Mac doesn't sleep or wake - Apple Support
http://support.apple.com/en-us/TS5357
Your computer cannot wake from sleep
Make sure your computer isn't powered off by pressing the power key for one second.
If you're using an external display, make sure your display is not powered off or unplugged.
If you are using a Mac desktop:
Make sure the AC power cord is connected securely to the computer and outlet.
Make sure the AC power outlet it is connected to is working properly.
If your computer is plugged into a power strip, make sure the power strip is not turned off. Check to make sure other items connected to the power strip are receiving power.
Your computer is slow to wake from sleep
If you see a progress bar when you wake your computer from sleep, this is normal. The computer is waking from safe sleep.
OS X Recovery and sleep
The system software your computer uses when started from OS X Recovery allows display sleep. Your computer does not go to sleep on idle while started from Recovery unless you are using a Mac notebook that is not connected to AC power.
Additional troubleshooting
If the steps above do not resolve your sleep-related issue, try these additional recommendations.
Reset SMC
The System Management Controller (SMC) is involved in managing power on your computer. Reset the SMC on your Mac if you are having difficulty sleeping or waking your computer.
Reset NVRAM/PRAM
Nonvolatile RAM (NVRAM)/Parameter RAM (PRAM) stores some power-related settings.Try resetting NVRAM/PRAM if you are having difficulty sleeping or waking your computer.
Test with external devices disconnected
Some external devices can prevent your computer from sleeping. Try disconnecting items other than your Apple keyboard or mouse from the built-in USB, Thunderbolt and Firewire ports on your Mac. If this resolves the issue, try reconnecting your external devices one at a time until you find the device preventing sleep or wake. Check the documentation that came with the device, or contact the device manufacturer for more information.
Try Safe Mode
Check to see if the issue still occurs when the computer is started in Safe Mode. If this resolves the issue, it could be related to a third party software item such as:
a login item
a startup item
a third party kernel extension
Try another user account
Try creating another user account, or log in as guest. See if your computer sleeps and wakes properly from the additional user account. If it does, your issue may be related to one of the following:
a login item
an app open in the original user account
You can disable login items from the Accounts pane of System Preferences. Try opening only one app at a time in the original user account to determine which app is preventing sleep. If you isolate the issue to a particular app or login item, check its documentation, or contact the developer of that software for more information.

[Solved] Screen bug after display sleep

Hi,
I have a Asus N55SF (Intel HD and Nvidia GT555M with Optimus).
When my screen wakes up after DPMS off (I mean only the screen suspend, not the system one), it's totally white, and I see leds becoming grey then black (like a cloud). Then it stays like this, the only way I found to make it working again is to put the computer in sleep mode and wake it up.
I can reproduce it, just waiting for the screen to turn off, or manually typing:
$ xset -display :0 dpms force off
I found a similar issue here: http://www.linuxquestions.org/questions … ost4501106

This seems to be fixed now. In the last update, kernel and drivers (and a lot of things) were updated, so I don't know which one fixed the bug...

ARD 3.3 Will not Wake Machine After Long Sleep

We are using ARD 3.3 on our network. We have found that ARD will not wake machines after they have gone to sleep and stayed in that state overnight. If I manually wake the machine and put it to sleep, it works fine. If I wake the machine and put it to sleep for several hours, it still works fine. The problem is completely random and only seems to happen when the machines have been asleep overnight. There are three machines this occurs with, I will describe each one below. I have a sneaky suspicion that it is our Firewall appliance causing the problem, but would appreciate any other input...
Machine #1
Intel Imac 2.8Ghz core-duo
OS X 10.5.8
4GB 667mhz DDR2 SDRAM
Problem: Occurs 98% of the time and is very consistent on this machine
Machine #2
PPC G5 Imac 1.9Ghz
OS X 10.4.11
1.5GB SDRAM
Problem occurs about once a week to once every other week with this machine
Machine #3
Intel Imac 2Ghz Core Duo
Mac OS X 10.5.8
2GB 1067Mhz DDR3
Problem occurs once in a blue moon
I have tried the following troubleshooting steps with machine #1 because it seems to have the problem so much...
1. Tried another user account
2. Tried removing power management plist located in HD --> Library --> Preferences --> Systemconfig
3. Tried resetting the SMU
4. Tried to repair disk permissions
5. Ran FSCK -FY from single user mode
6. Ran AHT for 17 hours straight with no errors
7. Booted to clean install of OS on external FW drive with user ported to FW drive.
BTW: Our firewall appliance is an Snapgear SG560 with the latest firmware.
Thanks for any input much appreciated...

I cannot wake up any computers even if asleep for a few seconds. ARD 3.3 has broken a lot of features such as copying files by dragging from a remote connection to desktop and it no longer reports Current Status correctly.
AWFUL update. Apple please fix this or explain how to downgrade to 3.2
I can no longer use this in the school where I supervise 50 Macs.

IMac (Mid 2011) Does not wake up after long sleep

Hi People,
Having issues with my Mid2011 iMac (21,5", 2.7GHz). Just upgraded to 12GB RAM (2x2GB original + 2x4GB). System runs fine, no issues.
But when system goes to sleep for a longer period (a few hours) it will not wake up again. Neither by Keyboard/Mouse interaction (Bluetooth as well as USB) nor by pushing the powerbutton. I also performed the PRAM and SMC reset as described in the apple support resources.
Feeling a bit lost. Any Ideas?
Thanks in advance for any help!

Addition:
Performed a test of the RAM with memtest. No erros found. Also forget to mention that the Mac has also Software updates and firmware updates installed.

Problems switching users and recovering from long sleep sessions

I upgraded my 2008 MacBook Pro to Mavericks and am now having issues with switching users and recovering from sleep. I can sometimes go to the login window but the system hangs when switching from one user to another. It often hangs after long sleep sessions.
Often I am finding that switching off and back on i sth easiest solution but I am getting a bit sick of it. Anyone have any suggestions?

funkyblue:
I usually leave my Pismo on and allow it to sleep. I find that waking from sleep and general functioning of the computer works a lot better if from time to time (I do it at least weekly) I shut down the computer, start up in Safe Mode, log in, empty Trash and reboot normally. The emptying Trash part clears the font caches.
You should consider doing other maintenance procedures, if you don't already. Gulliver's Mac OS X System Maintenance has good ideas with linked resources.
Please do not hesitate to post back with further questions or comments.
Good luck.

Why does my screen freeze after it goes to sleep?

I have a Mac OS X Lion version 10.7.4
If I don't shut down my computer after each use and it goes into sleep mode, when I return the windows are frozen and when I move the mouse around, it blanks out the screen.
I have been able to figure out that pushing the "help" key on my keyboard, will stop the mouse from blanking out the screen wherever it moves across, however, all the windows remain frozen and I cannot click on anything even to try and shut down my computer. I have to shut it down by using the power button.
Once I restart my computer it is fine, but this problem will reoccur whenever it goes into 'sleep' mode.
Any help here?

I have been having the same problem with my MacBook Pro -2010 though. It just started a few weeks ago; can't seem to get the to screen stay on long enough to log back in; it goes back to black within seconds. I have tried all the different buttons; esc works sometimes after holding the power button down for a few seconds. Eventually the log in screen [or the screen I was at when I closed the top] will come back on.
I hope I can find the answer to this as I can't afford a new machine right now. Besides, it's only a year old but out of warranty.

OK. If you believe that.
When the disk is starting to die it can be bad for a moment and then be good for a while. If there was no problem while you were checking it of course it shows up good.
I tell you those are the signs of a disk that is about to die.

Screen saver no longer working after Lion upgrade.

Hi,
After standard upgrade about 2 weeks ago (mid July 2012) the screen saver no longer works. I mean I can certainly access the application and the desktop can be made to cycle through different photos etc. But when I configure the screen saver it just refuses to go into screen saver mode at all.
I'm not seeing too much occurance of this through the postings which is a bit worrisome as I'd thought this would be a much wider issue.
Cheers,
Herbie
