Bizarre psychedelic display upon waking from sleep

does this mean a logic board failure is imminent? the screen showed nothing but a bizarre, seemingly random collection of pixels in all colors - almost like multicolored tv 'snow.'
I ran the hardware test disk, and it said the logic board 'passed,' but i'm not sure how it can test whether or not it's seated correctly.
in any case, i've also been experiencing other display issues (black screen, typically), most commonly when waking from sleep.
this is my wife's computer, by the way, and it's a desktop replacement - no travel, so it hasn't been abused at all.

Does an attached external display show the same effects
as the internal one? The supplied adapter should allow
a second display to mirror the internal one, and this may
help troubleshoot the extent of the hardware failure.

Black screen upon waking from sleep

Hello,
I have an intermittent problem with waking my entry-level MBP from sleep; on some occasions, the screen remains black instead of the system waking up and displaying the Finder.
Recently, upon waking from sleep, the authentication dialog displayed, I typed my password and pressed return, the dialog dismissed, the screen remained black, and the wait cursor displayed without spinning.
To recover, I needed to force power down and cold reboot.
system.log (in Console) contained the following entry at the time of the crash.
Aug 14 07:39:51 BF-H-MBP kernel[0]: NVChannel(GL): Graphics channel exception! status = 0xffff info32 = 0xd = GR: SW Notify ErrorAug 14 07:39:51 BF-H-MBP kernel[0]: NVChannel(GL): Graphics channel exception! status = 0xffff info32 = 0xd = GR: SW Notify Error
The entries surrounding the one above were as follows (the next to last one evidently was the final entry before the forced power down).

Can someone diagnose the problem based upon the above Console entries?
Thanks in advance!

Hi,
Thanks for taking time to post.
My question is different than the one your posting answers.
My question is, what is the diagnosis of the problem based upon the Console log entries that I've posted (rather than "How do I recover from the black screen?")?
Cheers!

User Name Upon Waking from Sleep

Hey guys,
We're given the choice of entering a password upon waking from sleep. I kinda want to take it one step further and have the user name erased too so that people have to enter the user name and the password upon the computer waking. Does anyone know how to do this or if it's even possible?
Thanks for any help.

The only way I can think of would be to log out rather than just put it to sleep or let it go to sleep. However, if you have a good secure password there really isn't too much reason to require the additional step.
There may be a way to do it but I can't think of one.

Detect display when waking from sleep?

Is there any way to force the display detection when waking from sleep? I find that if the mini wakes before the monitor is on, i get a blank screen. When the monitor is on before waking, everything is normal.
I have the DVI-Detective, and the problem is actually worse when using it -- nothing is detected when waking up, no matter if the display is on or not.
My specs:
OS 10.5
C2D, 2Ghz - 2GB RAM
Sharp Aquos 52inch
All standard HD resolutions work fine - it's just now a matter if figuring out how to force the mini to detect the display...
Surely there must be a way to do this?

Great that you got it working. It seems what is happening when the TV is switched off is that the Mac can no longer see the EDID data. Basically, it's the same as if a hot-unplug event had occurred from OS X's perspective. The mini thinks the TV's video cable has been unplugged, so it thinks it is running headless, which of course it is not. And for some reason not completely clear to me, when the TV's power is restored, a hot-replug event is not triggered and the mini still thinks it's running headless. Maybe you are right that it is removed from the list of connected devices for good. But it isn't supposed to work like that.
The DVI Detective is the right tool for the job in cases like this, so it's good you have one and it's good you got it working. I agree it would be nice if there was more override control within OS X for times like this when things go wrong. But if more TV and 2nd/3rd tier monitor makers paid more attention to computer plug-and-play, then these things would work right in the first place. Your TV is in violation of the plug-and-play standard because the standard calls for the host (Mac mini in this case) to be able to power the ROM and I2C bus within the TV even if the TV is in a powered down state. Clearly your TV isn't doing this.

Missing sound + missing USB power (sometimes) from Thunderbolt Display when waking from sleep

Hi
Two problems - one of which is driving med crazy!!
Have the latest updates, and the display is connected to a MBA (mid 2011).
The two are almost alwayes connected, and every time I wake the MBA from sleep, the Thunderbold Display does not "support usb sound" - the sound options are only MBA and headphones. Only a restart will give me the option to use Thunderbolt as sound output: WHAT TO DO!?!?!!
Sometimes when waking from sleep the USB in the Display seems to be "off" - the will not charge my devices (iPhone, iPad etc.). Only reboot seems to fix this... I have seen this in other discussions but not found a permanent solution - any thoughts?

Same here but reinstalling OSX is a bit drastic. I solved the problem by deleting a preference.
Go to Macintosh HD then System then Library then Preference panes then Sound.prefPane
Delete Sound.prefPane (you need to type your password).
Logout or restart.
This has happend twice this week so WHY is this suddenly occurring?
Hi,
I found this solution in the forum, but I can't find it again. I had cut and pasted it into a text file, because it solved my problem. I just don't want to take any credit for it. It did work for me. I had no problems for 3-4 weeks with the monitor, I have had the sound problem since last Friday. Very frustrating.

Sluggish upon waking from sleep

when I wake my Mac Book Pro from sleep, my mouse reacts strangely (erratically, sluggishly, etc) for a good 30 seconds. Anyone experience anything similar? Thanks.

Not sure if you've fixed this issue already, but are you using the iStat Pro widget by any chance? I was experiencing the exact same problem (erratic mouse behaviour after waking from sleep), and it was resolved when I removed the iStat Pro widget.
Not to cast aspersions on this particular widget or anything, but removing it seemed to resolve the issue for me.

Bizarre app behavior after waking from Sleep Mode

My iMac Core Duo runs like a top. It is fast and quiet. I have no problems with applications, both Universal and PowerPC. I maintain it with everything that I suggest others do in posts.
But, there is this one strange quirkiness that I have put off mentioning because I kept hoping that each new OS X update would address the issue. It has to do with waking my Mac from sleep mode with it logged into my user account. Not every time, but most of the time, if I put my Mac to sleep or it goes to sleep from inactivity while it is logged into my user account, I experience strange application behaviors upon waking.
For example, upon awaking Mail.app will contact my .Mac account and download any new mail that has arrived. But, if I try to open any of this mail, instead of opening, Mail.app will open a new outgoing email addressed to whomever sent me the mail I tried to open. Quitting and restarting does not solve this problem. Other apps demonstrate similar bizarre behavior. To only way to solve the issue is to log out and back into my user account.
However, if I log out of my user account and then put the Mac to sleep from the Login Manager I don't experience this issue. So at night I always log out before putting the Mac to sleep.
Anyone else experiencing similar issues? Any ideas on solving this? Do you think it is a bug in Universal Mac OS X?

Sorry this isn't a solution, rather is a commiseration. Often after my iMac wakes from sleep mode it refuses to see my internet connection. I have to unplug and reset my DSL modem to force the computer to see that it exists.
It sounds like the problem might be related, does anyone have any brilliant suggestions?
Thanks,
Lonnie

What causes spinning beach ball upon waking from sleep

I have a 4 year old iMac that has recently developed an intermittent problem. If I put it to sleep, sometimes on waking up, the hard drive access seems to stop. I hear a tap sound as though it was trying to read the disk, but it gets stuck and a spinning beach ball appears instead of the cursor. I can move it around, but I cannot perform any actions. The ball will stay forever if I let it.
Another variation occurs shortly after wake-up, where I start to click on a file on the desktop or even an icon in the Dock. The name will become highlighted and then the same spinning beach ball appears.
The only cure for the behavior has been to shut it down and reboot. It then works fine.
The weird thing is that I have just been using it for 6 hours straight with out any hassles... until I will put it to sleep!
I have tried running Disk Utility from the Leopard System Disk as well as repairing permissions and I have used Disk Warrior 4 . It seemed to allow about 6-8 sleep cycles before the symptoms re-appeared.
I verified the disk and repaired the permissions again yesterday and all seemed OK. Yet today, when I started up from sleep. the system froze. The only cure so far is to never allow the hard drive to sleep. I put the display to sleep after 15 minutes but the hard drive continues to spin.
I am concerned that not sleeping the hard drive will do harm to it.
I am using OS 10.5.8 on a 233 Ghz Core 2 Duo iMac
I have Parallels 4 installed and cannot tell you if the problems started after a PC session.

HI Studio Guy,
Welcome to the forums. When ever your having trouble with a computer; it's really a good idea to back every thing up. If your not backing up; http://support.apple.com/kb/ht1427 explains how to back up your computer to an external hard drive. (assuming your using 10.5 or 10.6)
You could try running a hardware test on the computer. http://support.apple.com/kb/ht1509
You could try a safeboot, it can repair lots of issues. http://support.apple.com/kb/ht1455
This article explains how to delete the sleep image; a bad sleep image can cause wake from sleep issues. http://osxdaily.com/2010/10/11/sleepimage-mac/
But if your hard drive is rapidly making a taping noise you may want to take it to a genius bar; they might recommend replacing the hard drive. http://www.apple.com/retail/geniusbar/

Scrambled display after waking from sleep...

I have a problem, probably with the computer, not the OS. Whenever the computer wakes up from sleep, the screen becomes all "messed" up, or scrambled. The keyboard still works, because I can enter my password, but the screen just moves to a different state of "jumbled". Powering down and restarting, and everything works fine. It only happens when waking from a sleep, and only about half the time.
I have a picture posted here of what the screen looks like, it allows screen capture, or at least use of the keyboard.

Any ideas ? Thanks

If you didn't buy 3 year Applecare, you would have a 1 year warranty, which would be over by now, unfortunately. If you bought three year Applecare, you are still covered.
You might still try an external display and see if you get the same artifact on it. If not, there's a chance that the problem is in the internal display and/or its connections. If you do get the same scrambled display, that would be a strong indication that it would be the graphics chip.
Also see if you get an error code from the AHT. If you do, that would confirm there is a hardware problem.
I don't think that this is a software problem, but you could always reinstall the OS to eliminate the possibility of software corruption.
Good luck!

MacPro Freezes upon waking from sleep

I have had my macpro for almost a year and have never had this problem. I have not connected any new peripherals to it or done anything new that I can think of. I have tried sleep and wake with them all disconnected, but still no luck.
Upon waking the computer comes back to life, however, the cursor does not move, and key commands also will not work. Only way to get it back to life is a hard restart. This began only a week ago, and was prior to the newest EFI Firmware update.
Is power consumption related to this possibly? Not enough juice to get her back online? or do I need to get her some coffee?

If it has too much equipment on the same circuit it can be a problem.
The freeze alone is enough to result in a corrupt directory.
Freezes on wake from sleep can be as simple as a bad USB cable.

2014 Mac Mini connected to Samsung s22b310b monitor colors bad upon waking from sleep.

Occasionally when I wake the 2014 Mac mini from sleep the colors on the monitor are very bright. I go into systems preferences and then display. I click on the color button and it will change back to normal. I have tried both a DVI to mini displayport and VGA to mini displayport. Problem occurs with both. What else can I try to prevent this from happening?

Fingerprint Reader not working upon waking from sleep for windows login

Hello,
I have a brand new T540P with a Validity fingerprint reader.
Rougly 80% of the time, the Fingerprint reader is unresponsive at the windows login screen after waking the computer from sleep. It works 100% of the time when booting from an off position, however. Once logged in, it also works 100% of the time. The issue only arises when logging into windows.
Things I have tried
-uninstalling/installing device in device manager and finger print manager pro software
-setting fingerprints through both fingerprint manager pro software (lenovo) OR through the built in windows fingerprint control panel options
-disabling "allow windows to turn off this device to save power" in device manager.
I should note as well that I have another T540P that I ordered as a replacement. Both models experience the same issue.
Is this a platform wide issue affecting all T540P models? This is frusterating.
Solved!

Your report is the first we have ever heard of this issue on T/W. It does not happen on my T/W systems here (with or without 30 Day Standby enabled). The other reports I heard of this problem came from X240.
I just want to confirm with you - the problem happens after coming out of Sleep (and not Hibernate), right?
Can you tell me exactly what you are doing? e.g.
1. Use the computer normally (is AC attached or not?)
2. Close the lid - the computer goes to sleep (or do you go to sleep some other way?)
3. Open the lid 2 hours later (or how long)?
4. are you using a dock?
The more info you can provide, the better. Thanks for your help.
Also please let me know what BIOS version you have.

Diamond shape momentarily displayed when waking from sleep

Hi
A couple of days ago when I woke my MBP from sleep I was a bit surprised to see a large diamond shape (it may have been a cube rotated through 90 degrees but it was only visible for about a second so I didn't get a great chance to look at it) appear in the middle of the screen before my desktop was displayed. This isn't something I've seen before and it hasn't done it again since. It looked like it was a silvery, grey sort of colour.
Does anyone know what this should be and, if so, is it anything to be concerned about?
Many thanks.

No recognition of external LED projectors upon waking from sleep.

For many, many years, I simply plugged my MBP while it was asleep, turned on the projector, woke the computer from sleep, and the computer would recognize the projector (and the projector would recognize the computer...). This worked in any of the classrooms.
Since "upgrading" to Mavericks, this sequence does not work. The computer wakes, but does not recognize the projector. The projector does not "see" the computer. The only way I get them to communicate is to restart the computer. This has been taking up valuable lecture time at the beginning of every class. Upon restart and opening up Keynote, the files I had open don't automatically come up - i.e., I have to reopen those files from the finder as if they had not been open previously.
I've tried this in three different lecture rooms, each of which gave me no troubles before. The only difference is Mavericks. Any help?

Of course I meant VGA, not LED. Sorry!

Finder opens to iDisk upon waking from sleep/opening lid

Every time I open the lid on my 17" G4, finder pops up and idisk is selected. Not really a problem, I guess, however, it is rather annoying. I don't recall making any changes.

try maybe -
system prefs> energy saver> and deselect 'wake this computer when a modem is detetected' something like that - deselect all internet type waking settings.
or open up idisc> prefrences> and there may be a wake from sleep setting somewhere (not used idisc myself)
