Display turns off until I close and open lid

Hi,
Like many others I have a problem with my display with my new PB. Sometimes when i re adjusts the angle of my display, the screen goes black. Like others, I can vaguely view the display in bright light, but the light has to be really bright if I want to see the slightest.
The weird part is that after the computer has been to sleep, the screen lights up again. So when the screen goes black all I have to do is closing the lid and open again. I've had the PB for a month and the problem has just accured 3-4 times. Should I send it to Apple for a repair?

When the screen is open and black...what happens if you touch the keyboard or move the trackpad?

Kernel_task reaches high CPU % after boot, mac is then superslow until I close and open the lid.. why?

I've had my macbook pro repaired a few weeks ago (new battery and keyboard).. Ever since then every time I boot it its superslow ... + with high activity on kernel_task.. When I close the lid and open it after 5 seconds again the problem is gone.
What could this be? Is it a hardware or software problem?
Thanks,
Lisa

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
Copy a line of text in this window to the Clipboard.
Paste into the window of another application.
Wait for the test to run. It usually takes a few minutes.
Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal 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 Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Firefox will hang on a website then everything else will no longer load and forces me to close and open firefox to get it to work.

As the question says I am having several issues with Firefox lately. I've tried disabling every addon, disabling JavaScript, running it in safe mode - no addons. Nothing seems to work.
I'll be on pandora listening to music, I open a new tab and go to a site like facebook. If that page does not load or hangs, my browser will no longer allow me to go to any other site until I close and open the browser. (Of course closing the tab that caused the issue). This happens about 10+ times every day, and I've supported firefox for years but this issue just keeps getting worse. It started when I upgraded to FireFox 6.

Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

Display Turns Off After Opening Computer

I have a very annoying problem of my display turning off and not turning on until I restart my Macbook Pro by holding down the power button.
For example, I will close my computer (power cord not plugged in) and it will go to sleep. If for some reason the computer turns on while it is still closed (this happens when I pick it up/move it around sometimes) and I then open the computer, the display will be on momentarily and then turn off leaving me with a black screen. The only way to turn the display on again is to restart my computer.
Another example: I might close the computer with the power cord in. I will then unplug the computer (still closed) and walk somewhere, then open the computer. The display will be on for a few seconds and then turn off, leaving me again to restart my computer.
The third example is the worst. Sometimes with the power cord still in, sometimes with no power cord, the display will just be blank when I open the computer.
With all of the above occurrences, I know the computer is running because I can see the caps lock key light change when I press it.
Does this make any sense? Please help me, I will be going to college on Tuesday and I would really like to have it so I don't have to restart my computer every time before class.
My display was not always this way, it has just been like this for a few months.

PB freezes when idle, need to close and open display to un-freeze

My PB seems to go to sleep fine when it's been idle for awhile and I've left the display open but when I go to use it, it seems to be frozen. The display comes back on and the curser moves but nothing happens. If I close the lid and re-open it, it will do everything I asked it to while frozen (ie, if I clicked on a window it will go to it or if I clicked on a menu, it will open it). It seems to be getting worse now though. The first time I close and open the lid after a freeze-up, the screen goes black and you can see the curser but nothing else. It will work again fine on the second close and open cycle. All this started happening when I got it back after having the HD replaced. I have done the ctrlcommand+PR trick. Nothing changed. Anyone have any answers?

Is the Home button physically broken? If so, you can use the multitasking gestures to get to the Home screen (the four/five finger pinch).
See Settings > General > Multitasking Gestures to turn ON.

I downloaded Macfee security and parental control. The settings have gone back to basic settings but if I try to customise the toolbar by add the "home" icon or adding "contact" to bookmarks until I close and when I open they are gone. Any ideas

Make that four.
If you have any commercially advertised/available antivirus software installed on your Mac, completely uninstall this per the instructions on the AV developer's website.
Antivirus software can slow down the normal operation of OS X and can negatively affect OS X performance and operation.
Do you have apps like MacKeeper or any other maintenance apps like CleanMyMac 1 or 2, TuneUpMyMac or anything like these apps, installed on your Mac? These types of apps, while they appear to be helpful, can do too good a job of data "cleanup" causing the potential to do serious data corruption or data deletion and render a perfectly running OS completely dead and useless leaving you with a frozen, non-functional Mac.
Plus, these type of apps aren't really necessary. They really aren't.
There are manual methods to clear off unnecessary data off of your Mac that are safer and you have complete control over your Mac and not just leave a piece of auto cleaning software in charge of clearing off data off of your Mac.
Their potential of causing OS X issues outweighs the implied good and benefits these types of hard drive or memory "cleaning" apps are written to do.
Plus, the software companies that write these apps make it hard to easily uninstall these apps if something DOES go wrong and these apps work in a way where you have no recovery or revert function to return your Mac back to its former, working state in the event something does go wrong.
It is best to never, EVER download and install these types of apps.
The risk to your system and data is too great a risk!
Search the web to learn how to correctly and properly uninstall these kinds of apps.
They all uninstall differently.

Macbook pro 15" and 17" display turns off whilst working then.......

I have 2 macbook pros. One 17" and the other 15" both are the non unibody ones. The 15" had this problem a while ago but my 17" never did it until today and then it did about 5 mins ago.
Whilst I am working (never seems to happen when I am not using it) the display turns off whilst working. The power light remains constant (ie:- not fading in and out when asleep). But here is the strangest thing. The mac repetitively makes the same noise as if it was ejecting a disk. Has anybody else had this? Know a cure? I recently upgraded to snow leopard but don't think this is a software issue.

I got the same problem with mine, 15". I bought it refurbished from apple store. I had this problem when i bought it then nothing happened for 4 months. But now my MBP has started doing it again. And i don't think it's a software issue. My display switch on after few sec, or 1-2 mins it's depends, and it's pretty random. i'm a bit of worry

Hello My ipads Power button is not working properly when I press it once it shows option to turn off instead of locking and some other display problems like it suddenly lockes down or display disappears ...Please help. Thank You

Thanks for that information!
I'm sure I will be calling AppleCare, but the problem is, they charge for the phone calls don't they? Because I don't have money to be spending to be on the phone with a support service.
In other things, it seemed like the only time my MacBook was working was when I had Snow Leopard without the 10.6.8 update download that was supposed to be done to prepare for OS X Lion.
When I look at the information of my HD it says that I have 10.6.8 but that was the install that it claimed to have failed and caused me to restart resulting in all of the repeated problems.
Also, because my computer is currently down, and I've lost all files how would that effect the use of my iPhone? Because if it doesn't get fixed by the time OS 5 is released, how would I be able to upgrade?!

Did the most recent update and now my TB Display turns off randomly on both my air and mini. I running TB Firmware Version: 23.6

When did you get this firmware version? My TBD is at 22.2 and the TBD bus is at 23.4. I thought I had the latest firmware.

My iphone 4s automatically getting turned off (blank black screen) and not getting started until full battery discharge, after updating to ios 8.0.1

My iphone 4s automatically getting turned off (blank black screen) and not getting started until full battery discharge. Even on long pressing power button - screen doesn't showing anything - not even "needs charging logo".
This is happening only since I have updated to new ios version (ios 8.1).
Is there anyone facing similar issue?? Any suggestion?!?

Hi jayla_mora,
Thanks for visiting Apple Support Communities.
It sounds like your iPhone screen is going blank and not responding.
You may find the tips in this article useful for troubleshooting this behavior:

HT201263 My iPhone 3G 16gb in white: I did all the things you mentioned, but it just keep looping the Apple logo and doesn't turn off until it is out of battery, and I am using a MacBook Pro 15inch Unibody if that does matter

If you are in Hong Kong, go to Digital Trade, 1/F, Sincere Plaza, Argyle Street, and it will cost you 120-150HKD, but before you go check that your power button and home button are working correctly, if not press as hard as you can, hope this will help.

Yoga display turns off after 1 minute

I'm having an annoying problem with my new Yoga related to the display and have not seen any other posts with a similar complaint so perhaps this is a simple fix that I'm just not able to sort out on my own. My display turns off after 1 minute of inactivity. The only means for changing behavior like this that I am aware of is through the Control Panel Power Options. My settings for "turn off the display" are 10 minutes on battery and Never while plugged in (note screen shot attached). Regardless of my settings, the screen turns off after 1 minute. I've changed the settings to multiple configurations and restarted with no change in behavior. Perhaps there's some other settings area, maybe something specific to Lenovo that I'm not aware of (since this is my first Lenovo laptop). Anyone with similar problems or insight?

This may be a Windows 8 issue. I finally fixed this problem by identifying the screen saver as the issue (and I wasn't using a screen saver). Type "lock the computer" into the search box after clicking the search charm, which brings up the screen saver dialog box. Mine was set to 1 minute, though I'd never set it myself. If you can't change it, choose a screen saver and you should be able to do so (and can then switch back to no screen saver). BUT, here's the problem. Other things you install (or settings within things you install) can apparently change and override whatever you type in for the delay time. Try applying your new time and exiting from the dialog box, then open it back up again. I was finding that it kept going back to 1 minute. To reset things so that you can get control again, type "user accounts" into the search box and when the dialog box comes up, choose "Reset Security Policies". Then you can go back to the screen saver dialog and successfully change the delay time.

W520 - now changes to "projector only" whenever display turns off in power save mode

I have my W520 in a dock with an external monitor. The display is configured to Extend - the external monitor is primary, and the desktop extends onto the W520 screen. I don't have a screen saver. I turn off the display after 30 minutes of inactivity. Until recently both the laptop and monitor screens would turn off after 30 minutes, and then both resume when I moved the mouse or pressed a key.
Recently, the system has started changing to "Projector Only" when the display turns off. After resuming from power save mode, only the external monitor activates, and the W520 screen is disabled. I have to use Fn-F6 to switch back to "Extend" to re-activate the laptop screen.
I have rebooted and re-saved the power plan.
Why has this happened, and how do I fix it?

Hi, timg11
I have a few questions so that I may gain a better grasp of this issue:
1) What is your machine type and model? You can find this information on the bottom of your machine. It should be in format XXXX-XXX.
2) What is your operating system?
3) Does this issue occur is the computer is not in the docking station? (Please try if you haven't already).
Thanks in advance,
Adam

White Stripes/Display Turning Off

Last night I noticed a bunch of white stripes flicker for about a quarter of a second on my display. This happened multiple times. I shut it down with no problems.
Today I had no problems until everything froze. I could move the mouse, but it would not change from a text cursor. I manually shut it down.
I turned it back on, after a few minutes I had the same issue.
I turned it off manually, unplugged the power for about a minute, plugged it back in and turned it on. After a few minutes the white stripes flickered. I decided to back up everything. After about 10 minutes, during the backup process, the screen went black. I could feel that the computer was still on, but the display was black. I manually turned it off.
I have now been on for about 30 minutes with no problems. The computer was very hot when the display went black. Is it possible that this is an overheating problem?
Any suggestions?

The iBook has a seperate display dimming (display turns off) and sleep mode timers. Go into the system preferences>energy saver to set these preferences. When your display turns off you should be able to reawaken it by pressing a key on the keyboard. Turning it off is not the best solution. If the problem happens while you are still using it or it doesn't awaken when you hit a key then you may need to post here again.

Macbook display turns off when booting Snow Leopard DVD

I have mid-2009 Macbook Pro and I hate Mountain Lion. I want to do a clean install of Leopard using the DVD (grey) that came with my computer. I loaned it to a friend recently and he had no issues. But everytime i try to boot from the SL DVD (hold C at startup) it behaves normally, until about the time it would go into the DVD startup screen. At that point the display turns off (not the whole computer, just the display) as if it has gone to sleep. And I can't get it to turn on again. I've also tried booting and holding Option and choosing the DVD as the boot drive. No dice.
Awhile back I created a Lion install DVD. I can boot to it just fine. But i don't want Lion either. Any ideas why this is happening? Thanks!

Press control shift eject, then any key to toggle the display from sleep/wake.

Display turns off until I close and open lid
