Screen blinks/flashes upon wake from sleep. is this normal?

I just got my Macbook a few days ago and started to notice that my screen flashes or blinks when it wakes from sleep. I have searched on Google and haven't seen any one post about it so I'm guessing this is normal. This is not the flicker of brightness that other people are talking about.
What happens is: I press a key or open the lid to wake it from sleep, and then very briefly for a second I will see the screen flash on (sometimes you can see a small image of the desktop), then it is black for a second, then the screen comes on normally. The delay of the screen coming back on after the blink seems to be getting longer so I was starting to worry this might be a problem. (granted the delay of the screen coming on is maybe like 2 seconds, but its noticeable) I had a Thinkpad previously and never noticed the screen acting like this.
If anyone can tell me if I need to bring this in to the nearest store or if it is normal I would appreciate it. I don't want to overreact as this is my first Mac and I don't have any problems so far. But I want to be safe if this is an indicator of future screen problems. Thanks!!

Take it to your local Apple store and they will send it off for repair. Or call Apple and they will send you a box to mail it in for repair.
I took my MacBook to the Apple store for the infamous screen flicker problem and they had the logic board and the LCD replaced. Problem is gone and the screen is better than before!

Click here for information; if the computer beeps three or fewer times, remove and reinsert the computer's RAM. If it beeps four or more times, it needs to be repaired. If it's a G5, it will ignore RAM modules that aren't part of a matching pair.

When mac wakes from sleep, the hard drive wakes but the screen is black

It's a problem I've been having off and on for quite a while with my ~2010 MacBook Pro. Sporadically/randomly, when I wake my computer from sleep or turn it on, the status light turns on and the hard drive makes sounds like it's on, but the screen stays black. The only way to get it on again is to manually hold the power button to shut if off and start it up again. Sometimes, the same issue reoccurs when I restart it and I have to manually restart it 5 or 6 times until it finally turns on normally, or I just get tired and give up. I've had everything done at the genius bar, from getting a new hard drive to running diagnostic testing. Nothing works. Any suggestions??

Power Mac G4 Quicksilver Won't Wake From Sleep

I have a Power Mac G4 Quicksilver 933MHz that will not wake up after it goes to sleep. It is currently running OS X 10.3, has had its hard drive replaced, system reinstalled, and been DiskWarrior'd. Haven't tried replacing the PRAM battery yet but get no indication its dead (clock keeps time wen off). It always connected to an Apple 17" Cinema Display--could that be the source of the problem?

Hi, Toolshed4!
Third Party USB devices and USB PCI cards are notorious potential culprits for no wake from sleep issues so please follow japamac's lead and look at them as potential culprits. Disconnect the external peripherals and test sleep/wake. Swap a third party keyboard and/or mouse with your Apple one(s) and test. Remove any PCI cards, and test. (It's perhaps good practice to reset the PMU after you add or remove an internal component.)
A Cinema Display, especially one with a built-in USB port or hub problem, could create an issue, though it would more likely to be one of not sleeping, rather than not waking. You might quickly check your system log for possible indicators of USB issues with the Display, if you have reason to suspect that its ports may not be functioning properly.
Resetting NVRAM in Open Firmware sometimes resolves the issue. Resetting your PMU as japamac suggested will take care of the NVRAM reset for you.
If the above didn't resolve things, please continue on...
Corrupt Energy Saver preferences are sometimes the cause. Quit System Preferences if it's opened and navigate to /Library/Preferences/System Configuration (folder) and delete the following preference files:
com.apple.PowerManagement.plist
com.apple.AutoWake.plist
(The AutoWake plist file may or may not be present, depending on whether or not you have/had scheduled sleep settings.)
Then navigate to ~/Library/Preferences and delete the com.apple.systemuiserver.plist preference file. Restart and test sleep again.
If your battery is old, it's a good idea to just get a new one. The worst that can happen is that you'll have a spare when you need it. They're about $5 online. If you go to Radio Shack with the one you have, they'll test it for you. Alternately, put a voltmeter on it and insure that you're reading at least 3.3 volts DC. New ones read 3.6 - 3.9 volts.

Power Mac G4 MDD won't wake from sleep mode

I have a Power Mac G4 MDD 1.25GHz with a 15" Apple display and running 10.4.
I can not wake the computer up from the sleep mode. It will not respond to the mouse moving, a mouse click, a keyboard key, the power button on the display or the power button on the computer.
The only thing I can do is force the computer off by holding in the power button (on display or computer) and restarting the computer.
The computer is set to go to sleep after 1 hour of no use (or the issue happens if I put it to sleep).
Any thoughts would be great.

This is for a Mac that won't sleep.
Here is KB article HT1776 with their tips.
Mine follow;
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.If you've set your Mac to receive faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Receive Faxes On This Computer box.
If that doesn't work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB cards.
Also, here is Apple doc.#305262 about PCI cards and sleep.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
Tristan Currier noticed this; "I have a Canon printer(shared) and my imac would not sleep. I opened up printer/fax in system prefs and noticed it said the printer was in use when it was off. Opened up the printer queue and noticed about 7 pending documents. Deleted them all and now it sleeps.
Check the printer queue!"
Good Luck!  DALE

Folder always opens when imac wakes from sleep

Don't think its a huge problem but when new imac wakes from sleep the same folder always pops up on screen(shaded in black). It always has to be closed before I can proceed with anything.Any suggestions would be appreciated. Also the folders name is always highlighted red. Thanks

Searching the web for "appcode.hex" the first item that I found was for something related to an Olevia TV.
A .exe file is a Windows file and will not run under Mac OS X.

Audio volume low when computer wakes from sleep - os x yosemite

I've been having an issue ever since I upgraded to OS X Yosemite, where the audio volume coming out of my external speakers is extremely low after I wake my computer up from sleep. The only resolution I have found is restarting the computer. Once I do that, the audio volume is great. If I were to boot up my computer after it has been completely shut down, the audio volume is also great. The issue only occurs after sleep. Anyone else having a similar issue? Is there another fix besides restarting the computer?
Speakers: Bose Companion 2 Series II (these are wired, not bluetooth)
Computer: Mac Pro - late 2013 - running Yosemite

This is a BUG. It has been submitted to engineering many times - unfortunately Apple has not done anything about it.   We have 5 Mac Pros, all 5 do the same thing after updating to Yosemite.   The PRAM / SMC reset is useless - we even installed a fresh OS on one of the machines (a suggestion of the level 2 Apple tech) same problem.   Clearly this is a system level bug.   Only way to get it resolved is to keep pounding the bug report site with requests.     The squeaky wheel gets the oil.   The problem is 100% repeatable on the machines that exhibit the bug.
In the mean time set up an applescript with this command and it will reset the sound - do not include the brackets :
<do shell script "sudo killall coreaudiod" with administrator privileges>
Run it every time you wake from sleep and you won't have to deal with the problem ever again.
Pretty lame that Apple has not fixed it even though the problem appears to be pretty widespread.

CD/DVD drive door opens when eMac wakes from sleep

I have two identical eMacs running OS 10.4.9 but for some reason one of them has a problem where the CD/DVD drive door opens by itself when I wake it up. Has anyone experienced this problem?
Thanks!
Brent

The same thing happens to my eMac - and it has not been serviced at all. I have been watching your post for a reply. Can anyone provide a bit of help as to why the eMac CD door pops open upon waking from sleep?
Grateful for your help,

IPod 4G always mounts for disk use when Mac wakes from sleep

My 4G iPod is always mounting for disk use when my Mac (10.4.8, Dual 1.8 GHz G5) wakes from sleep, even though the settings for the iPod has "enable disk use" unselected. When I launch iTunes (latest version) the iPod promptly is unmounted. I have restored factory settings, I have reinstalled the computer's OS and iTunes with it.
What is going on and how can I make it normal?
Dual 1.8 GHz G5 Mac OS X (10.4.8) iTunes 7.1, iPod 4G 20GB

UPDATE:
I have started to turn off Bluetooth at night before I put my computer to sleep. I HAVE NOT HAD THE FIREWIRE RANDOM DISMOUNT PROBLEM SINCE. I do not know if this is a freak coincidence -- but so far, so much the better for my firewire drive.
Hope this helps someone else down the line... eh hem...

Display Changes Resolution When Computer Wakes From Sleep

I have a MacBook Pro bought in May of 2006. In the last year, this problem has been getting progressively more annoying to me. When the computer wakes from sleep (not every time, but most of the time) the screen will flash blue, then reset the resolution to 640 x 480, I think. To fix it, all I have to do is go to System Preferences and change the resolution, but when I do that, it pops up two windows, like it thinks I have a dual display set up. To fix this, I always click 'detect displays,' and it fixes it, but the next time I wake the computer from sleep, it does it again. This isn't really an urgent problem, but I would expect my computer to behave a bit better for me.
Thank you in advance for any aid you might give me.
Lisel

Hi Lisel. I have a similar age MacBookPro that does the same thing. I don't really know how to fix it I'm sorry, I wish I did cause it's annoying. I just thought I'd let you know you're not the only one with this issue.
Basically, for some reason it thinks it has two displays connected, even when there isn't. To stop it being a total pain, make sure when it does come up with the two Display Pref windows to set them both to 1440x900, at least then when it does go dual display it won't be 640x480 and you can still read stuff.
I've also left the Display Pref icon on the top tool bar (next to the AirPort and Bluetooth and stuff), so I can just click that and Detect Displays. When it does that it figures out for itself it doesn't actually have two displays connected and so goes back to normal.
I know that's a workaround and not a fix, sorry. I'd be keen to know if anyone else has any better solutions:)
Thanks,
Mark.

10.4.7 kernel_task eats 70% of CPU only when computer wakes from sleep.

On my machine (FW 800), 10.4.7 caused: machine to slow perceptably after wake from sleep. Activity Monitor tells me kernel_task is consuming hundreds of times it's normal CPU cycles.
I installed a FRESH 10.4. Imported my files and folders. Upgraded all the Apple software EXCEPT 10.4.7 combo updater. The partition worked fine, before and after sleep. Upgraded using the 10.4.7 combo updates.
Again, kernel_task consumes 60-70% of CPU cycles after my Mac wakes from sleep. Note that it works fine when first rebooted.
As slow as it was, it was unusable. I reverted to 10.4.6 to get work done.

I have the very same problem on the same platform, except that I have 2 int. bootable disk drives. One boots 10.4.6 and has no problems at all. The other Boots 10.4.7 and operates perfectly, as far as I can tell from a few hours of use. It will continue to work just fine until I put it to sleep. On awakening, the Kernal Tasks CPU Usage jumps to 55% - 75% and does not decrease any further (ever). Restart or Shutdown restores perfect operation after reboot (but don't let him fall asleep).
I have repeated this dozens of times, with identical results.
The update was performed by the book. External devices disconnected, permissions repaired, disk verified by Disk Util. and DiskWarrior and the 10.4.7 combined update was used. Permissions and Drive Verif. was repeated after sucessful install. In my case, no other apps were effected. No Sys Errors were logged, No crash events, no Kernel Panics.
There are thousands of Sys Config combinations involving both hardware and sotware. This looks like a flawed release on this hardware. "Updater Beware", especially the first month after a major release like this. Look for a fix very soon.
Even so, the people at Apple have done extremely well over the last few years.
I know, because I work with a dozen or more Generic PCs and there has never been a trouble free update from the other side.
Having a second internal hard disk with identical OS and applications is like having a second computer in the same case. It is also a good idea to use backup software to auto-sync your user files in realtime. You can boot from one while repairing the other etc.

Time Machine Preferences breaks when I wake from sleep

I have recently started having a problem.
When I start my computer, everything is functioning fine. I am able launch System Preferences and open any preference pane and quit System Preferences and everything is fine.
When I put my computer to sleep and then wake it up, I have issues. If I open System Preferences, I can close it. If I click on Trackpad, I can close it. But if I click on Time Machine Preferences and try to quit System Preferences, it doesn't quit. If I try to Force Quit, I get the standard "this app isn't responding" error box.
I cannot quit System Preferences is any way. Force Quit does nothing and eventually the rest of my apps on my machine stop functioning. I have to hard reset my machine to get System Preferences back.
Anyone else seen this? I don't want to blame it on 10.5.6 but I think that this started happening after that.

So I have made a further discovery.
It is related to my non-Time Machine external hard drive. When it is connected I have the issue mentioned above, when it's not connected I have no problem. I re-formatted the drive and no longer have the issues with the System Preferences, but now, if I sleep, when I wake I can't shut down. It just hangs and I have to hard restart.
A couple of notes from the console log. When the "bad" drive is hooked up, I see the following message (multiple times when I wake up:
*kernel AppleYukon2: 00000000,00000000 sk98osx_dnet - recovering from missed interrupt*
Also, when I try to do the actual shutdown, I see this error:
*/usr/sbin/kdcmond[37] dnssd_clientstub read_all(3) failed 0/28 0*
So I feel like the issue is somehow connected to my eternal drive having a conflict with the wired network card. I am going to do some more tests.

Screen flickers when computer wakes from sleep

O.k., so I also had this problem when I updated to 10.6.8, but it's still here in Lion.........
When the computer wakes from sleep, I get a single flicker along the bottom 1/3rd of the screen, then everything's o.k.
It's just annoying, that's all. I've backed out to 10.6.7 on 3 occasions, and the flicker disappears.
Anyone else having this issue?
I'm running a 2010 Quad-core Mac Pro with SSD and 27" Display.
Bob.

Update:
I've now been to the local Apple store, and tried their display Mac Pro/27" Cinema Display combo, and guess what.......the screen flickers on wake-up.
I asked the guy in the store about it, and he says "oh yes, I see that. No-one has noticed that before, I wonder if mine does it at home".
I tried the Mac Mini with 27" Cinema display, and the 27" iMacs, and they were o.k. (no flicker).
So, this only affects Mac Pro's running 2560 x 1440 resolution.
I've booked another call with Apple Support. No doubt they'll still tell me to take my computer in for testing, even though I've shown they all do it (the guy in the Apple shop suggested that, even though I demonstrated the flicker to him on the one in the shop).
I wonder how long this will take to get a software fix? Problem is, the Pro is not mass-market (like Macbooks and iMacs), so it may take an awful long time.
In the meantime, I'm sticking with 10.6.7.
Bob.
