Black screen after MacBook Pro wakes from sleep; reason, solution?

Greetings!
I have 2 MacBook Pro machines; both are running the latest versions of OSX for their age.
The 2 GHz Core Duo is using 10.6.8 (2GB RAM) and 2.5 GHz Duo Core 2 is using the 10.7.x (4GB RAM).
Both are routinely used with external monitors. Every so often when either of the machines are put to sleep, the external monitor disconnected, and finally when the machine is woken, the native screen remains black and unlit. If the machine is connected to the external monitor, it shows its appropriate desktop but the finder bar is unavaible so nothing can be done short of forced shut down and a reboot.
Am I forgetting some simple short cuts (key-bases) to bring the native screen to life or is forced shut-down really necessary?

When my macbook pro wakes from sleep the curser is not there, no keys work and the screen is frozen so i have to reboot it

Sometimes when my macbook pro wakes from sleep the curser has disappeared, the screen is frozen and no keys work. I have to reboot.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Why won't my macbook pro wake from sleep?

My MacBook Pro 13" is awesome. What is not awesome is that I can't wake it from sleep sometimes. I have tried pressing keys, trackpad and power button with no success. When I restart, I get the login screen and it will immediatly go to sleep or it will let me type in the password and then go to sleep. What is going on here. I thought that Lion would fix this, but it did not. Anyone have any suggestions?

Everything seems okay with my computer. It did not want to wake up 1 time since my last post. I closed the laptop, let it sit for a few minutes and when I opened it back up it woke up and was fine. The only thing I can figure is there is something that happens after the laptop has been charging for awhile. It seems that everytime the computer didn't want to wake from sleep, it had been charging the battery or had just finished charging. Weird thing to happen. If you have this problem happen to you, try the steps mentioned earlier in this post (the answer from tjk) will probably fix it.

Why wont my macbook pro wake from sleep when i try to use it?

Blank Screens After Startup and Wake From Sleep

About half the time I startup my Mac Pro or wake it up from sleep, the screen will go blank, usually about 20-30 seconds after video appears on the screen. The system seems to be running, you just can't see anything.
I have had the screen go completely white, black or blue and occasionally, there will be a solid color with vertical lines throughout the screen. The only thing that will get display back is a forced restart of the entire computer.
I've zapped PRAM and run run hardware test with no issues reported but the problem keeps coming back.
I'm driving a Dell 2407 on my ATI 1900XT. Dell supplied a single-link DVI cable, could that cause issues with a dual-link port on the video card?

Intel Macs, especially MacBook Pros seem to be notorious for sleep issues...either not sleeping when supposed to, or not waking up from sleep properly.
My MacBook Pro has come out of the brief case hot as heck with a dead battery often enough, even with all the updates appled. If you listen to the MacBreak Weekly podcast, that's a common complaint of Merlin Mann, who can't figure it out with his machine, and he's no dummy when it comes to Macs. Not very encouraging, is it?
Still, what I would try is reinstalling the OS X 10.4.9 update. I've often read/heard on podcasts that it's better to manually install the larger Combo version of the updates. That seems to have fixed problems for me in the past.
Get the Intel 10.4.9 Combo Update here: http://www.apple.com/support/downloads/macosx1049comboupdateintel.html
Good luck.

Macbook Pro wake from sleep fails

I am having problems with my Macbook Pro 15" waking from sleep. I was not having these problems until I re-installed OS X a few weeks ago, and now almost everytime I close the lid and take it home from work it will not wake up properly. It appears to be "half" waking as I can just about make out the image on the screen, but the backlight does not come on, and I can not see a pointer so I have to hold the power button and hard reset it.
I have also tried downloading the combo update to 10.6.3 and re-applying that to see if that helped, which it seemed to as I had a few days without a problem, then this morning I took it out to a customers site and it didn't wake up again.
Anyone else having these problems? Anyone got any ideas for a fix?
I appreciate any help/ideas!!

Hi there.
Both my wife and I have started having this problem with our MacBooks in the last few weeks. On waking from sleep the screen is black (though in the right light you can see that it's active, just not backlit), and the Mac goes to sleep again within a minor or so. Both Macs are less than a year old.
I discovered a fix by accident: give the machine a sharp nudge once it's awake! Makes me think there might be a problem with the motion sensor, in hardware or software. May disable it if this continues.
Hi Mike,
I'm not sure this is really a solution to "sharply nudge" or slap your laptops. If the sudden motion sensor is bad, this is something we should be able to diagnose and have Apple repair. But I'm not entirely sure we have the same issue. For starters I have a 240GB SSD drive in mine that should have no sudden motion sensor, if I'm not mistaken.
These are bright, horizontal bolts, that shoot in perpendicular lines. The irony is that I cannot record them on-screen directly, but have to do so using a hand held camera. I also used the "Apple LCD Tester" and the striping does NOT appear on any of the solid images it kicks up.
I have yet to be able to isolate the source of the disruption and (as I mentioned before) it has a brand new logic board and the problem persists.
BTW, it's not my intention to hijack this thread. I think these threads are related and the only reference I've found in all of the discussions is the one mentioned here. I can start a new thread if I've violated protocol.
Thanks again for everyone's help.

Macbook Pro wake from sleep issue in Bootcamp

Hi,
My MacBook Pro is running 10.7.2 with the latest bootcamp software.
I use Windows 7 while at work and Lion when at home.
The issue I am having is that when I am working in Windows 7 and I put the MBP to sleep by closing the lid and when I wish to start using W7 again I just reopen the lid and everything seems to be fine but what I find is that webpages seem to start hanging.
If I open a constant ping to the default gateway of my laptop (time capsule) I notice that every now and again i will drop packets.
If I do the same on another Macbook no Pings are dropped during the same period so I know its not wireless interfearance or issue with the TC itself.
If I reboot the MBP and start in W7 again all is fine so it seems its only an issue with W7 and waking from sleep.
Any help would be appreciated.
Thanks
Gavin

How to automatically connect to wi-fi after turning macbook pro on from sleep (without pressing a button!)

Hi there, I was just wondering how to connect to wi-fi as soon as I turn my macbook pro on from sleep mode
The thing is, I constantly have to select the network i want, even though I've already set the location to automatic and even added the network to my preference list..
What else can i do?
I know a few friends who have the same macbook pro as me but do not have the same problem as me! And even they don't know what to do..

you've posted in the iPhone forum.

I occasionally have issues waking my macbook pro up from sleep mode and have to restart the computer. The apple store replaced the sleep part but the problem is still there

I occasionally have issues waking my macbook pro up from sleep mode resulting in my need to restart the computer. I dislike all of my programs opening at once when I do get the computer started becasue it slows the cpu down. The apple store replaced the sleep part but the problem is still there. Note: i never had this problem with snow leopard

I'm not certain but my new MBA 13...when in sleep mode comes back on from a black screen when I simply click on the left mouse button. Also, one time I did a SECURE EMPTY TRASH on files that totalled more than 1GB and it took so long that the fan kept increasing in speed so I pressed on the POWER button and the MBA shut...I was able to boot up with no problem. As a rule, I now only do secured erases for trash bin data totalling 500mb or less...anything above that gets a regular erase (dump).

Black screen on MacBook Pro Retina Display after installing Moutain Lion. Need Help!

My macbook pro (retina) screen went black after I installed Mountain Lion.
I got a HDMI cable to another monitor and the image worked nicely there.
But i cant get it back on my MacBook Pro! I tried taking out the HDMI cable, restarting, searching on settings configs..
What should I do?
Are there any drivers i should install to get image back on my MacBook Pro Retina Display?
Has this happened to anyone else?
Thanks in advance for all the help.

That helped me finding other people with similar problems.
But there is a major difference!
-They have a black screen after they login.
-My screen is black NOW! And I'm only using my BRAND NEW rmbp with the HDMI cable to my TV!
This isnt good at all and I would like to solve it asap..
I tried reinstalling Mountain Lion, taking out the hdmi cable and rebooting many times.
Until now, nothing!
Is my screen broken or maybe my video card has some problems?
I hope not! I just traveled from the US to Brazil and I dont want to search for an Apple Store here.
Any tips or ideas are welcome, thank you.

Time Machine turns itself on after my Mac Pro wakes from sleep (every time)

Hi,
I have a 2009 Mac Pro and it currently has Lion on it (10.7.4), but the problem I am about to explain started when the machine was running Snow Leopard, so it doesn't appear to be an OS-specific issue.
I do not currently use Time Machine, I use Carbon Copy Cloner and some online backup solutions to handle backups. I did use Time Machine for a short time on this machine just after it was introduced, but I didn't end up using it for long and the external drive I used for the backups is no longer in service.
The problem is this:
I have Time Machine off and I have all of my drives (I have 4 drives in my Mac and an external drive) set not to be backed up for good measure. Time Machine will stay off like it should except in one instance. If I put my machine to sleep, when my Mac wakes, Time Machine is instantly turned on and I get a warning telling me no backup drive has been selected and that I should pick one. I go into the Time Machine preferences and turn it off. It will remain off (I've checked the preferences to be sure) until the next time the machine is put to sleep. Time Machine will remain off, even through reboots. It is only waking from sleep that causes this.
I've tried zapping the PRAM, getting rid of the Time Machine preferences and even logging into a new, unused user account and testing it from there and the problem continues. This is really starting to annoy me. I wouldn't mind having TM on, but having to click through the warning every time my Mac wakes from sleep is frustrating.
I don't want to have to buy a new external hard drive and let TM backup to the drive because, as I said, I've got my backup solutions handled already and I'm not willing to put yet more money to use a feature I don't need right now.
I've done searches online and asked around and no one has been able to help me yet. So I thought I'd try here.
Anyone have any ideas?

Do you see a wake reason in Applications>Utilities>Console?

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!!
Macbook Mac OS X (10.4.8)

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!

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.

Late 2013 Mac Pro wake from sleep crashes - which logs to look at?

I started encountering wake-from-sleep crashes with my late 2013 Mac Pro a couple of weeks ago. Prior to that the system had been pretty solid. Other than app and OS updates installed from the App Store, I can't think of any software changes that might be responsible.
What logs should I be looking for that could be helpful in diagnosing the problem? Looking at other posts where people have been trying to diagnose similar issues I see people posting portions of panic logs that show which modules were loaded and might help point to a culprit, but I can't seem to find a log with a panic message in it.
I had thought I'd determined my Anker USB3 powered-hub was related to the crashes, as when I disconnected it from my system I went several days without a crash. Today I reconnected the hub with just a few devices on it and got a crash. I disconnected the devices but left the hub attached but got another crash. I then disconnected the hub again, assuming I'd proved it was the culprit, but the machine has now crashed twice without the hub attached.
I'm running OS 10.9.4. Looking at other reports people reported some specific programs that added kernel extensions that were suspected to be the problem, but I don't have any of those programs installed on my Mac. The problem doesn't happen every time I wake the machine, but has happened at least four times today alone (after about three days of no crashes.)

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.
I know the report is long, maybe several hundred lines. Please post all of it anyway.

Black screen on macbook pro 13in 2011

A few weeks ago my screen went black while I was having a web cam chat with my wife. I was able to hook it up to my flat screen TV and it is working fine but not on my main apple disply screen. The apple icon on the back isn't lighting up and I can see shadows on my screen now after I did a PRM reset. Everything is working the way it should just not the screen. I'm living in China so my options are limited to where I can go to get it fix. I don't want anyone telling me its the mother board when I know it isn't (as I was told before along with a very high price for a new one).
Can anyone help me with a self repair option?
Thanks.

That helped me finding other people with similar problems.
But there is a major difference!
-They have a black screen after they login.
-My screen is black NOW! And I'm only using my BRAND NEW rmbp with the HDMI cable to my TV!
This isnt good at all and I would like to solve it asap..
