Screen flashes when going into screensaver/sleep

Hey Guys,
Every once in a while when my macbook is supposed to start the screen saver it will just start flashing a black screen. in order to make it stop i have to restart the computer. i was wondering if anyone else experienced this.
thanks!
Laura

Yup, this has just started happening on my Powerbook G4... it doesn't seem too damamging but I don't know why. I found your post while trying to discover a solution. I'm going to try reloading my Pixelbreaker Screen saver to see if that fixes it.

Screen flashes when waking up from sleep, Macbook Pro Retina 13" early 2013

Hey guys,
I have an issue with the wake up procedure on my new Macbook Pro Retina 13". This is how it looks: http://youtu.be/pBK8vRiVdX4
When my computer has been in sleep mode for a longer time (approximately 1-3 hours) it does this strange thing when I open the lid. It is black for a time and suddenly there is a blue flashing screen before it goes to the desktop. This process is about 10 seconds.
Does anyone know if there is a solution for this? Have you had the same problem? I called Apple support this morning and he told me to reset SMC and clear the PRAM, but the issue is still there.
Please let me know if you know something about this.
Kindly,
Mikael

i had the same problem too and i think i could isolate its cause. I tried a few things on my 13 inch retina macbook pro like switching off functions like ''put hard disk to sleep when possible'' but this wasnt a solution to the problem... after alot of playing around with my macbook, i realised that this flashing problem only occured when my macbook was scaled up to any resolution other than the native resolution... when i went back to the native resolution, the flashing stopped and my macbook started almost instantaneously after opening the screen... you should try it out... and tell me what you think...
think it is pretty annoying that we get this issue when scaled up to some other resolution and wish there is a solution somewhere online to solve this... but for now, i think it is quite an annoying bug but still not something i cant live with...
tell me what think about it:)

Mountain Lion crashes when going into deep sleep?

Hey guys,
I recently upgraded to mountain lion from lion on a late 2011 MBP.
I have no problems during the day time with anything, but when I leave the computer to sleep overnight it doesn't wake up in the morning.
It shuts down and when I try to turn it on it gives me a pattern of 3 consecutive beeps. Sometimes it doesn't give me any beeps and just gives me a grayed out login screen and a bar loading on the bottom. In the latter case, it does eventually wake up but with the beeps it's a no go and I have to hold the power button to restart it. I never had any of these problems in Lion. Any thoughts as to what this could be?
I tried PRAM, SMC Reset and creating a new user account. I also ran an extended Apple hardware test which reported no issues.
This is the log preceding the crash/shutdown:

I can't deal with this issue, because I like to use my macbook to charge devices overnight and that's not possible with it shutting down. So if there is no solution what's the best way to go back to Lion?
Am I the only one with this issue?
Thanks for any help.

It sure would be useful to be able to look up these Failure codes. Searching apple's site like this produces strange, useless results.
I see Failure code:0x1F006500, like the OP; googling for it brought me here.
Similarly:
I recently upgraded to mountain lion from SL on a MacBookPro4,1 -early 2008 MBP (expired AppleCare), and switched to booting off an SSD in the ExpressCard/34 slot.
When I leave the computer to sleep overnight it doesn't wake up in the morning. It is completely off, and boots from scratch when I turn it on. It can sleep briefly.
I have NOT tried PRAM, SMC Reset or creating a new user account, or run an extended Apple hardware test.

Strangely, there's no mention of 'hibernate' in my log files after 19:03 last night, even though I was up 'till 'round midnight.

I have a new MacBook Pro Mid 2012 and it goes into deep sleep when I disconnect if from AC power.

I have a new 13" MacBook Pro mid 2012 and it goes into deep sleep when it is disconnected from AC power. I have to press the power button to wake it up. Is this a known issue or is there something wrong with the MacBook Pro?

There are a few threads about this around. Its a known issue for 2012 non retina users, not sure about Apple. It should not work this way and Apple has not put out an update to fix it yet. Check out these threads for some workarounds. I think I saw if you reinstall and don't update one of the updates you get normal functionality back. Otherwise there are some terminal changes you can make to make it operate mostly normally. I made some changes in terminal.

HP B210a goes into a sleep mode if not used for several hours,

Running my B210a eprinter in windows vista. The printer goes into a sleep mode if not used for several hours. The power button is slowly flashing dim then bright, and I need to manually touch the printer's screen to enable it to print. If printer not used for several days, the only way I can make it work is to unplug and plug. Any suggestions or help appreciated. J Rice

Why does the elements 13 change resolution when going into the editor -- it is huge and unusable

why does the elements 13 change resolution when going into the editor? -- it is huge and unusable

Many mysteries...
Which is your OS version ?
Your screen is 1920 by 1080 pixels.
The problem appeared after having worked normally.
When we select a picture from the organizer (album) and click on the edit button. The editor software changes the entire computer resolution from 1920 x 1080 to 640 x 480 (very unusable).
That's not clear for me: did you click on the 'Edit' button on the bottom right part of the organizer, or did you use the menu or the right click popup menu to open the editor? In the second case, you are in the editor workspace.
We tried right clicking on the Elements 13 icon, select properties and under compatibility we made sure that "run in 640 x 480 screen resolution" was de-selected, and it was. Cannot find any properties window for the editor?
The editor has its properties in the 'Edit/preferences' menu, but there is nothing about resolution there.
Just to be sure : when you are in the organizer with the left 'Folders' panel shown, you highlight one of those pictures to edit. Then you right click and choose to "go to folder". Do the images are shown as 'offline' ? If that is the case, the original are on an external drive which is not connected, and what you are seeing is a 'preview' copy on your computer with 640 x 480 resolution.

Help: Macbook goes into deep sleep instead of sleeping

Any time my Mac is supposed to go into sleep, like when I leave it alone for 15 mins or close the lid, it goes into deep sleep (hibernates). How do I fix this?
Also, it started happening after I changed the starup disk from Windows to OS X through the boot camp control panel in Windows.

Just reset the SMB following these instructions: http://support.apple.com/kb/HT3964 and still having the same problem. However I realized two key things:
The computer goes into Deep Sleep mode whenever I tell it to Sleep (Even if I use the Sleep button in the Apple menu)
The above only happens when the power adaptor is plugged in. When running on batteries Sleep seems to work properly
While typing this up I just realized that a widget I have called Deep Sleep for dashboard might be causing my problems, and sure enough... it is. Apparently there is a setting on there that lets you make your Mac's "regular" sleep mode Deep Sleep and I probably turned this on without realizing it. For anyone who's reading this I'll try to keep you posted on if this fixed the problem or not... if I don't post anything else on here you can assume it's fixed. Watch out if you use the Deep Sleep widget

My iphone5 screen flashes when trying to make a call. I can't access any of screen features.

My screen flashes when trying to make an outgoing call. I am unable to access any of the screen features such as keyboard etc.

Could be a problem with the proximity sensor. Are you using a case around your phone or a protective film attached to the screen? If yes, remove them, to make sure that the sensor is not covered.
Also try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose data by resetting.

My (2008) macbook pro, running 10.5.8 runs for about 30 seconds and then goes into deep sleep mode. After significant difficulty awakening, it runs for 30 seconds and....start repeating here. It did this once before about a year ago.

.....and then goes into deep sleep mode. When it (finally) awakens....it runs for about 30 seconds and.....start repeating here.
And yes, I've shut dwn and restarted multiple times, rebooted in terminal mode and run fsck, rebooted and reset the parameter ram, yadda-yadda......
Anybdy got any ideas?

Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on Mac portables with a battery you can remove
Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.

My MacBook was acting weird so I restarted it and when I login a white screen flashes and goes back to the login page. Help?

My MacBook was acting weird like sometimes I would log on and I wouldn't be able to type my password for a couple seconds,but it usually logged in after that. Then I left my computer open after installing the recent update after that all my applications were not responding. So I shut it down, when I turned it back on about an hour later it went to this loading screen and then to the login like usual. After I tried logging in a white screen flashed and it went back to the login/ password screen like nothing happened. Any ideas on what happened and what I can do to fix it?

Reinstall OS X;
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
