Mbp fall asleep, log in screen black

when i leave my mbp for a few minutes and return to try and log in the screen is black. when i move the mouse around it removes some of the black to show portions of the log in screen. what is going on here?! i have a late 2010 macbook pro 13 inch.

I had a simular issue with my IMac. Apple replaced Logic Board & Graphics Card. When they repaired, still had same problem. I went into System Preferences, Security & Privacy, General Tab, and I unchecked the log out after ** Minutes of inactivity.
That stopped the screen from freezing up.

Wifi won't stay on if computer falls asleep

When my computer falls asleep the wifi won't stay on. I have to turn Wifi off and then back on for it to connect to the internet. Anyone have this problem? Anyone know how to fix it?

My MBA will often disconnect from the wifi while it's asleep --especially if I close the screen rather than leaving it to fall asleep with the screen open. I then need to go to the menu, find the home network, select it, and reconnect. It's not a big deal for me, but I can see how it might be for others.
Not sure if that's the same thing as what you have, but if it is, then yes, I have that problem too. And no, I'm afraid I don't know how to fix it.
Good luck!

Random black screen after log in screen

I have a week old top spec rMBP, I migrated my settings from my older MBP using migration assistant without any issues, my problem is random which makes it difficult to describe, when I reach the log in screen and insert my password click enter, sometimes the computer opens normally and at other times I get a brief flash of white which looks like a horizontal line but it is very rapid so I may be wrong, and then the screen goes black and nothing happens, no menues or options, all I have is the power button to shut down. I restart and it can take a variable number of attempts before it will get beyond the log in screen, 6 attempts it the most so far !
I have an appointment at the Apple store tomorrow but just wanted to know if there was something I was doing wrong to save the journey, the machine works fine once up and running, I have done the disk and permissions repair via disk utility but it does not seem to make an difference, there used to be some resets using various key combinations and there was the remove the battery reset option but of course that is no possible now.

You could try two things (but I doubt that either will work).
Reset PRAM and NVRAM.
Reset the SMC.
Give them a try as last resort. As I said, I doubt that either will fix your problem, but it's worth trying.

Black wallpaper on log-on screen after wakeup.

Apols, but I can't find anything realting to this elsewhere. Am still a newbie with macs (though I'm loving it!). Have set my wallpaper to the MAc pictures within OSX, but every time I wake my MBP from sleep, the bakcground is black - note this isn't a crash or "black screen" as I still get my log-on ID boxes etc. When I start up from turned off the Aurora background appears at log-in, so I don't know what's gon on with the wake up log-in screen... Anyone with any ideas?
Many thanks!

Have a look here "Topic : Desktop Wallpaper Issues" (http://discussions.info.apple.com/thread.jspa?threadID=2132964). Of particular note is if you have EarthDesk installed.
If nothing there works, may also want to look at "Topic : Desktop picture reset on startup (Missing com.apple.desktop.plist file)" (http://discussions.apple.com/thread.jspa?threadID=2482650&tstart=2).
Hope this helps.

Display falls asleep and won't wake when connected to new Haswell MBP

For over a year now I've used my 2007 Macbook Pro and my 2004 20in Cinema display together. I woud dock my macbook pro and just use my cinema display as my main display.
I attempted to do this with my brand new macbook pro today. Purchased a Mini Display port to DVI adaptor and I can get the display to appear on my the 20in Cinema Display, but when I close my laptop it falls asleep and so does the monitor. I've been able to wake it up for about 10 seconds but then it'll fall asleep again and I can't wake it up any longer.
Has anyone had a similar issue like this and is there a solution out there?

Hi @LMG123,

My iMac G5 randomly falls asleep during use.

A few weeks ago I was using my iMac and suddenly lost control of the cursor, cursor became invisible and computer went to "sleep" (ie; screen went black, "woke up" a few seconds later after moving the mouse). This problem has persisted in all sorts of conditions and uses. Usually the intial episode is followed by another shortly after. The problem happens a lot while streaming video on the internet. However, the computer also falls asleep when using photoshop.
The problem began when the hardrive was nearly full (15 GB left on drive). I cleared out many of the larger files (lossless music files) to gain 87 GB or so. Problem persists. I mostly use this computer for typical web stuff (email, facebook, videos on youtube and the like) and graphic design (Illustrator and Photoshop). Hard drive had never been defragged. I usually restart the computer when problem gets really bad.
I've searched various forums for a solution. Many argue about defragging, some mention OS reinstall, no real clear consensus seems to exist about why the problem occurs or what to do about it. Any ideas?
Specs: Mac OS X, 10.4.11, 2.1 GHz G5, 1 GB DDR2 SDRAM

Your problem sounds more like a heat problem. Try resetting the SMU:
   1. Shut down the computer.
   2. Unplug the computer's power cord.
   3. Press and hold the power button for 5 seconds.
   4. Release the power button.
   5. Attach the computers power cable.
   6. Press the power button to turn on the computer.
If that doesn't clear things up defragging won't do anything much, the best would be to try an
Archive and Install http://support.apple.com/kb/HT1710
which will give you s shiny new OS, but keep your prefs and settings. Make sure you select that option when reinstalling.

Macbook Pro OS X Yosemite 10.10.01 Log In Screen Issue

After my computer falls asleep and I touch the mouse pad to wake it, the password entry log in box is shifted to the left about 1/2 an inch. To fix this, I have to enter my password and wait for the computer to reload the log in screen, at which point the password entry log in box is back in the correct position and I am able to enter my password and successfully log on to my user. This does not happen every time the computer goes to sleep. I have not attempted any troubleshooting with the exception of restarting the computer. Any thoughts would be appreciated.

Very similar thing happening on my iMac (Early 2009) running Yosemite. I have been able to replicate my problem a few times. So I'm logged into my Admin account, and my wife then logs into her (standard) user account (while my user account is still running). She then logs out, and I log back into my user session which is still running. As the desktop appears and the Finder icons show my login session is abruptly terminated and I'm back at the login screen with no users actively logged in.
I've just installed an SSD into my optical drive and created a Fusion drive, and then restored from my Time Machine backup, and the same thing occurs on my new Fusion Drive setup (I suppose I shouldn't be surprised because it is exactly the same OS, User accounts and etc). Think I'll reinstall the OS over the top of my existing one to see if that fixes it.

Hello my MBP 15" stops at grey screen after apple logo disappears

hello, my MBP 15" stops at grey screen after apple logo disappears, what can i do about this? ive tried booting into safe mode but screen turns blue with black lines also tried resetting NVRAM and PVRAM but still stops at grey screen, also tried using applejack, it shows no problems at all, says my disk volume is ok but the screen still stops at grey during start up, havent tried the installation disk thing because i dont have my installation disk with me

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 10
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

IMac takes a while to fall asleep.

when I'm ready to walk away from my iMac I either use a hot cornet to start the screen saver and password protect it (screen lock) or I go apple (menu) sleep (password protecting it as well).
I have noticed that recently it takes longer and longer for it to fall asleep.
when I click apple sleep the screen goes black but the screen light is on (I figure it's not gonna fall asleep in < 2 secconds, I don't either) and the fans keep going... and I figure 3 secconds is reasonable.
but it's been taking 10+ secconds.
also wake up time is slow too.
should I try clear my cash? tempfiles? or get a defrag program?
thanks in advance.

I think lots of people will help you get rid of any annoying cash you have!

Seriously, do you have anything that might be running in the background that the system is waiting for or gracefully suspending? Maybe a few external drives that need their buffers cleared first? Things that were not an issue the first times you used the system but may have been introduced. I don't think your Cache is the problem though.

Macbook Pro unable to get pass the Log in Screen.

Hey hope someone can help.
Okay so last night I was using Windows, I shut down, then a few hours later I switched it on to go onto my Mac, but it took forever, I left it though and eventually I got to the log in screen, I entered my password and it was loading then the screen went blue/gray (not sure I think both) and went back into the log in screen again... I did this numerous times before giving up and shutting down. Went to sleep, woke up and resumed this...so I decided to see if I could log into my windows, which it did just fine, I'm on windows typing this right now.
I have run the apple hardware test, extended too, and I have recieved the error code: 4SNS/1/40000000:Th2H-63.000 (No idea what that is)
I have also tried booting from my start up disk that came with my Mac. It gives me the Apple logo on the gray screen then ejects my disc, gives me this long story... kind of goes: panic (cpu 0 caller 0x00431da3):"unable to blah blah... Tells me to restart or shutdown.
I looked at my disc and I think its cracked, So I have to get that replaced.
I think I have to archive and install, I really don't want to lose my music, as I haven't backed it up. 400 songs or so nothing much, I'm not worried about the other stuff as that is all backed up.
Long story short can someone tell me what's going on with my Mac? why am I still able to use windows fine? Has windows done a hit on Mac OS? lol. Is the solution to replace my install disc at Apple? I really don't know, any help would be greatly appreciated thanks, I'm just too tired and can't Google anymore :P
(I have a small partion of 32GB dedicated to Windows Vista.)

"I have run the apple hardware test, extended too, and I have recieved the error code: 4SNS/1/40000000:Th2H-63.000 (No idea what that is)"
Neither do I. Suggest that you take your MBP to an Apple Store or an AASP.
"Is the solution to replace my install disc at Apple?"
Yes. You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support for a nominal S&H fee. *You'll need to have the model and/or serial number of your Mac available.*
Since you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number. Here's a list of links to all of those -

MacBook Pro w/10.6.8 requires me to sign in twice at initial log-in screen before loading

My MacBook Pro w/10.6.8 requires me to sign in twice at initial log-in screen before loading.. In addition, after Safari 5.1.7 has been open for a few hours the browser stops loading pages and then the entire computer freezes and I have to do a forced reboot with the power button. The first push of the power button brings up the four options screen: "sleep, restart, turn off, logout" but they don't work. I have to force shutdown.
I don't have either of these problems from a safe boot. However a boot from a clean "Test" administrator account still requires me to login twice before the desktop loads.
If I login once as either Test or my User Name then choose the " back" button then switch to the other login option before pressig the return key, I only have to login in once at the new login screen.
This problem began after I partitioned my 500GB HD with a 10.6.8 partition--the problem partition-- and a Lion 10.7.4 partition (to avoid iCloud issues with Snow Leopard). The Lion partition does not require double login. I have not done anything yet with the Lion partition except software updates.
I have also been having LCD problems (according to recent Genius Bar visit, not related to the NVIDIA 8300 problem). Sometimes (every 2-3 times I start the MBP) the MBP will reboot but the screen will be so dark I can't see the cursor and can barely see the desktop. The brightness is set at max and pressing the buttons up/down don't affect the dark screen. Usually I restart and the screen appears normal. This problem occurs with Safe, Test and User Name boots.
Thanks for any suggestions

I have the same issue and eventually revirted to logging in web wise to emails and have found that its not so bad- but the moment app wants to access mail it slows down and have had had issues again.
I know that Mac products when accessing emails have a tendancey to semi download images- and was told that this can be the issue by a friend( not sure how rellable this is) but have noticed a coralation between the two factors.
I know that there are issues with hotmail when on certain devices ( had the warning form hotmail's site)- but still have yet to be shown how to remove my email from Mail- if yo have any ideas I might try it.
Please if you have any advice of how to remove main email that would be great and it may be a option for you.

Macbook pro 5,2 Falls asleep unexpectedly

My 17" MacBook Pro 5,2 has a problem with staying awake... At random (increasingly so) the screen will flicker and it will put itself to sleep...
After I wake it up again, I'll see growl notifications about magicprefs (wich is standard after awaking my macbook). Does anybody have an answer as to how to keep my macbook pro from falling asleep every 2 minutes? Thanxzzzzzzzz...... Huh?

Apple Portables: Resetting the System Management Controller (SMC)

My 2008 MacBook Pro running Mountain Lion now falls asleep regardless of what is or is not happening.

First the good news. My 2008 MacBook Pro, which used to not fall asleep unless forced to do so (lid closed or command issued) now falls asleep. The bad news is that it will fall asleep even if a program is doing something and I'm not physically doing anything. More accurately it will fall asleep when uploading to Box.net, or when downloading map updates for my GPS. It also falls asleep when EyeTV is converting shows, but not when it's recording shows. I have third party apps that can keep it awake, but shouldn't my MBP recognize that something is happening and to not fall asleep?

Mac keeps falling asleep for no reason

So, I have a MacBook pro w/ retina display. It falls asleep when I am using it. All the time. And then makes me re log in. I don't want to shut off sleep mode, as I like it. But it won't stop.
Known issue? Fix? Thank you in advance.

We have no way of see your Mac so you are going to have to tell us
exactly what model of MacBook Pro you have
disk space
amount of RAM
what operating system are you running
