Horizontal streak on monitor milliseconds before it turns off?

Hey, so as the title suggests, I've been seeing this horizontal line over the middle of my Macbook Air Mid-2013's screen whenever I turn it off. It kind of jumps up a bit before the screen turns black. I'm wondering if anyone else has seen this on their mac, or if this just happens to all 11 inch Macbook Airs?
Thanks!

damaged monitor feed cable.
test same by moving monitor slowly while on. If it changes, thats is.
If so then contact Apple for appt. for free in shop diagnostic evaluation for repair.

External Monitor causes MBP to turn off

I got my MBP back in April. I also got a Dell 2005FPW external monitor that I hook up to my MBP when I am at my desk. My MacBook Pro gets really, really hot, just like others and apparently that is ok. I guess it is no longer a "laptop" because it is too hot for a lap. Anyway, aside from being uncomfortable, the heat usually does not cause problems. However, I have found that when I plug in my external monitor and have both screens going and have my processors maxed with some video applications my MBP will just turn off. Not sleep, or anything else, it will simply turn off. This is while it is plugged into the power so it is not a battery problem. How can I get my MBP to stop turning off, aside from not plugging it into my external monitor and running intense applications?
Thanks,
Jonathan

Do the random shutdowns happen when you don't have your MBP
connected to the external display?
I have tried to duplicate the random shutdowns without the monitor attached, but to my touch, it feels as though the MBP does not get nearly as hot as it does with the external display attached.
Do the shutdowns happen with less intensive processor
tasks?
No, it is usually when I have multiple programs open and both cpu's are near their peak.
Are you using the display cable that came with the Dell
display? Is the cable firmly seated in the display and the
MBP?
Yes, I am using the cable that came with the Dell display. Yes, firmly seated.
Have you installed any third party software that uses
kernel extensions (like a temperature monitoring program)?
No, but I have downloaded TechToolDeluxe, I have just not run it yet. Should I?
Do you hear the fans come on at any time before it shuts
down?
Not that I noticed but I was not really paying attention.
A little more background information. I originally found this problem because I would have my MBP at my desk at home, hooked up to the power supply, external keyboard/speakers/monitor. I would start a video processing application running on a long task and go to bed. I would come back and the MBP would be off. I would turn it back on and the task I had it working on would be only partially completed.
So I took it to work where I sit in an air conditioned office and have it on a glass-top desk. I tried to hammer it with tons of programs being open and video processing applications. The CPU's would run on max for hours and the MBP would get plenty hot but would not shut donw.
It is only recently that I realized that the shutdowns happened only when connected to the external monitor. So I thought that perhaps the video card for the external port was producing just enough extra heat to get the MBP to shut down. To test this I ran the same video processing application that I usually run over night, only this time I left the external monitor detached. No shut down.
Does the TechToolDeluxe program measure heat? That would help to quantify the heat levels.

I have lost my iphone and did not have Find me set up. Is there any way that Apple or anyone can track the last location of my phone before it turned off?

I have lost my Iphone last week. I know this has been a while, but I am desperate. I have talked to At&t and there is no way they could track my phone with it turned off. So I was wondering if there's any way that we can check the last location of the phone before it died? And also, if there's any way we can ping the phone in case it was stolen and was turned on? I hope to read ur responses soon. Thank you.

If you did not setup Find My Phone, I'm afraid yo're out of luck. There is no practical way to track your phone.

I am using an alternate monitor. Can I turn off the laptop monitor and still operate normally?

I am using an alternate monitor with my MacBook Pro. Is there a way to disable the laptop monitor so that the laptop can be closed?

Here is how it works, if you wnat to use it:
Apple Portables: How to use your computer in closed clamshell (display closed) mode with an external display
My son put his big monitor up on 4 inch blocks, then opened the MacBook on the desk below. Once he turned off Mirroring, he used the laptop display as an extension of the big display, and left the MacBook open.

My iphone 4 screen has been frozen (on that rotating circle thing it does right before it turns off) for about 6 hours now!

This morning it was working fine and then it went to the lock screen and I tried to "slide to unlock" and it wouldn't go. Then it became frozen on the lock screen and I tried everything from holding the lock button to try to shut it down, plugging it in to the wall, plugging it into the computer. Then I just left it in my room for about 30 minutes and when I came back to get it, it was doing that rotating circle thing it does before it shuts down and its been doing that for about 6-7 hours now!! I have absolutely no control over my phone. I tried putting it out in the sun to drain the battery quicker and eventually shut off but that hasnt been working either! The frickin phone wont turn off!! Does anyone know what to do about this?! Thanks:)

Turning off internal monitor while using external one

Hello, Apple Support Communities.
Before OSX Lion, anyone could turn off internal monitor while using external one, by waking up computer with lid closed, and the internal monitor will be kept turned off. But now, -I wonder what made Apple to think this way- Lion will turn on the internal one back on.
I don't care about all sorts of reasons why should I or shouldn't I desire to this. I just want it, because I have nice big monitor, which is apparently bigger than my Macbook Pro. Besides using double monitor will just exhaust my poor laptop. -mine is bit old-
I found ridicoulus answer from community, saying I should try fridge magnet. Sorry, but I don't want risk my whole computer, especially my HDD from getting magnetic damage. It happened so many times, -thanks my little bro- so now I am sick of magnet. I don't think Apple will cover this AKA magnetic damage anyway. -It wouldn't just damage, just erase your HDD-
So.... Any helpful insights? Thanks.

Nevermind. I found solution. Though it cost me 24 bucks.
Now Apple is seriously making me to consider to roll back to sucking Windows.
Thanks Jobs!

Client Monitors Not Turning Off at Login Screen

I manage a video production system with 16 Mac Pros and 4 Xserves all on an XSan System. I use Workgroup Manager to handle Access and other stuff. Starting two months ago, The computer monitors on all Mac Pros will not go to sleep when they are on the login screen. The monitors are supposed to turn off after 30 minutes when no one is on the computer. I have tried everything I can think of. I have set this in Workgroup Manager for the computers individually and the computer group they are apart of; the local admin on each client; and even in the client root account using Unix commands from Remote Desktop. Still the monitors are allways on if the login screen is showing. If a client is logged in, the monitors shut off correctly after 30 minutes of idle time.

Many Open Directory problems can be resolved by taking the following steps. Test after each one, and back up all data before making any changes.
1. The OD master must have a static IP address on the local network, not a dynamic address.
2. You must have a working DNS service, and the master's hostname must match its fully-qualified domain name. To confirm, select the server by name in the sidebar of the Server application window, then select the Overview tab. Click the Edit button on the Host Name line. On the Accessing your Server sheet, Domain Name should be selected. Change the Host Name, if necessary. The server must have at least a three-level name (e.g. "server.yourdomain.com"), and the name must not be in the ".local" top-level domain, which is reserved for Bonjour.
3. The primary DNS server used by the master must be 127.0.0.1 (that is, itself) unless you're using another server for internal DNS. The only DNS server set on the clients should be the internal one, which they should get from DHCP if applicable.
4. Follow these instructions to rebuild the Kerberos configuration on the master.
5. If you use authenticated binding, check the validity of the master's certificate. The common name must match the hostname and domain name. Deselecting and then reselecting the certificate in Server.app has been reported to have an effect in some cases.
6. Unbind and then rebind the clients in the Users & Groups preference pane. Use the fully-qualified domain name of the master.
7. Reboot the master and the clients.
8. Don't log in to the server with a network user's account.
9. As a last resort, export all OD users. In the Open Directory pane of Server, delete the OD server. Then recreate it and import the users. Ensure that the UID's are in the 1001+ range.

My iPhone 4S has started to turn off before its out of battery. There is no pattern it is completely random so I don't know when it will turn off, when I try to turn it back on it says it needs to be charged.

As soon as I plug it in to the charger it reboots to the same percent it was originally on before it turned off for example today it turned off on 10% I tried to turn it back in and it said out of battery so I plugged it in to the charger and it immediately rebooted showing the apple logo and the phone was on 10% when it was fully rebooted.
I was wondering do I need a battery replacement or is this something more serious.
Many thanks.

Hi Lukeohiggins,
If you are having issues with your iPhone unexpectely powering off, you may want to try the troubleshooting listed under Power/Battery > Will not turn on, will not turn on unless connected to power, or unexpected power off in the following article:

Macbook Pro Retina (late 2013) & 10.10.1 cannot detect the external monitor is turned off

I connect my MBPr (late 2013) to a 24" Dell monitor via HDMI using a high quality audioquest hdmi cable.
When I turn off my Dell monitor, the MBPr did not detect the monitor is being turned off.
Let's say I opened a chrome browser and I move it to the external monitor. If I turn off my Dell monitor now, the chrome browser will not automatically move back to the MBPr screen.
I have the same scenario if I just power on my MBPr now and not power on the Dell monitor. I will do this if I need to do some small stuff (like typing this post) int he middle of night and I don't want to turn on my Dell monitor.
I am not sure if this is a problem or this is a normal behaviour of the MBPr. I was like this when I was on Mavericks.
PS. If I connect my Lenovo laptop to the same monitor and I turn off my monitor, the opened applications will go back to the Lenovo screen.

The hardware supports DP1.2 and MST but unfortunately at present OS X Mavericks does not.

MBP turns off during boot

Hello!
My mid-2010 MBP is having some issues. It is no longer under applecare. Last year, when it was still under applecare, I had a problem of the display going black many times per day while doing even simple tasks. I believe they replaced the logic board and everything worked just fine after that.
However, last night my laptop suddenly went black while viewing a PDF. I tried opening and closing the cover, nothing could get the screen back. At that time, the keyboard was still lit up and the caps lock button still worked (light would turn on and off when pressing).
I did a hard-reset.
The laptop screen lit up like it was starting, and then died. Tried again, nothing. So, I waited about five minutes and tried again. The screen lit up, the apple appeared, and then the laptop died.
After many attempts, I have seen it do many different things. Sometimes it dies before the apple appears. Sometimes it dies after that, but before login screen. Sometimes it dies on the login screen. Usually the longer I wait, the further it will go - however, even when stone cold and not warm at all after waiting hours, it will still only run for ten minutes before it turns off. Sometimes if I can get all the way through startup, it will run for a minute, or five minutes, or ten minutes, but it always fails. Sometimes it turns completely off, but sometimes only the display goes black and the keyboard stays lit. I can even change the keyboard illumination up or down when this happens. Its about a 50/50 chance whether the display will die or the whole laptop will die. Whichever one it is, though, it still requires 10-15 minutes before I can try again, or the machine will just fail halfway through startup.
I have also tried starting into bootcamp. It worked for five minutes in Windows and then died.
I have tried booting up while holding shift, but it was taking a very long time for the progress bar at the bottom to fill, and halfway through the laptop shut down.
As I said at the beginning, the logic board is one year old.

After sitting for a day, I started up the laptop and made it all the way through login. I let the machine sit without touching anything for about twenty minutes, nothing happened.
I then opened Chrome, and as soon as I began typing into the search box, the entire computer shut down, and restarted by itself.
Halfway through restart, the screen turned black. I waited, and after a minute the keyboard lit up so I knew it was at the login screen, though I couldn't see anything. I typed the first letter of my name, pressed enter, typed my password, and pressed enter again.
I presume the computer is logged in and sitting at the desktop now...I have the laptop set up so that if I move the cursor to one corner, it puts the display to sleep. When I do this with the track pad, I can see the keyboard lights dim, then light back up again when I move the cursor back out of the corner.
Anyone have any suggestions? How can I get my screen back?

Windows 8 "Turn off the display" setting not working

Hi all, I've got a TP W520 which I upgraded to Windows 8 with all updated Lenovo packages including the power mgt driver, Lenovo settings dependency package, and the newly installed Lenovo settings metro app. I'm seeing the following problem when trying to set a time for the monitor to shut off under Control Panel -> Hardware and sound -> Power Options -> Edit plan settings: - If I set any time other than never for "Turn off the display" such as 1 hour for example, the monitor will get turned off as soon as the screen-saver launches from the Windows 8 Lock Screen. - I'm not seeing this same behavior if I let the screen-saver launch while sitting at the desktop screen, problem is only seen from the Windows 8 lock screen. You can test this as follows: - Set "Turn off display" to any time i.e. 30 min - Change your screen-saver to launch after 1 min to test this - Type ctrl-alt-del then click lock to enter the lock screen, then let the screen-saver activate after a minute. - Once the screen saver tries to start, in my case, I see the monitor getting turned off and the screen saver doesn't even start. The monitor shouldn't get turned off until 30 min elapses. I'm suspecting some kind of bug with this which is still outstanding and I look forward to feedback from others on this issue. Thanks, John

My iPod Touch will not completely turn off or connect to iTunes

I disconnected my iPod and did what you are supposed to do to turn it off. The little thing that circles round and round before it turns off all the way will not stop. It won't turn off no matter what I do. iTunes says it cannot connect to my iPhone (it is an iPod Touch) and that there is some kind of error. I went through all of the troubleshooter steps including uninstalling and reinstalling iTunes. What should I do? Will it fix itself when the battery finally dies?

- Have you tried resetting the iPod:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- Placing the iPod in recovery mode and then restoring the iPod via iTunes? For recovery mode see:
iPhone and iPod touch: Unable to update or restore
For the future. saying:
"I went through all of the troubleshooter steps"
Really provides us with no information since we do not know what steps you are referring to.

PS4 turns on for split second then turns off (Not BLOD)

My PS4 was purchased via preorder on launch day here in South Africa - Friday 13th December. After working for 2 days,it now fails to turn on. I've read about the blue light of death that just pulsates continuously but what I'm getting is a beep and blue light for less than a second before it turns off completely with no light.
If I then press or hold the power button again, I get nothing. I have to unplug it from the wall and replug it in and then if I press the power button again, it does the same as before - beep and split second blue light before going dead. Here is a video I took of it:http://t.co/VIrDS9KI1G I can't get into safe mode. If I try to hold the power button down, it just does the same as above. It doesn't stay powered long enough to reach 7 seconds. I've also tried removing the HDD and booting without the HDD in to try and force safe mode but again, it does exactly the same as above. I've tried using different plug points and adapters that I know work and I've done so with no other devices plugged into these points or adapters. In my highly amateur opinion, it feels like a power supply issue where power is cutting practically immediately.

It's a power issue, I've noticed this because I was moving my PS4 from downstairs where I tested it, to my gaming room where it'll live FOREVER! lol... and the power was unplugged, but I touched the button as I lifted the console. It beeped as if it was going to come on, then because it had no power it just went off again. Just like you describe. So the console is acting like it does when it has SOME power, but not enough in my opinion.
Once I got it upstairs and plugged in the power, it came on and all was ok.
I recommend:
Giving the PS4 ITS OWN PLUG SOCKET, don't plug it on a multi-adapter where it's power might be shared/weakened.
Give the PS4 a moment of being plugged in so it can store enough power to turn on.
Make sure your cables are all good,
