MacBook pro screen turns off randomly?

• U2913WM screen turn off randomly

  So I got this monitor ultra wide nine of the store with 3 year warranty. I had these questions of the day 1. I came home to repair, but given that the problems occur at random I'm afraid that the retailer they come back to me it works normally after the test for 30 minutes.

  The questions are:

  1. the screen turns off (screen with backlight black still on) or it will freeze randomly. To resolve this issue, restart the controller using the power button, which in turn will not immediately respond, but will keep wait me for 6 to 10 seconds until the monitor turns off eventually. Monitor back to work normally after the restart until the next random freezing. Sometimes this happens when changing the resolution (for example launch a video game). This can happen as often as 5 - 10 times a day.

  2 monitor sometimes not into mode 'sleep' when the computer is off, put to sleep, or not used for a long time. Instead, the screen will turn white with the backlight, as in the previous edition, and the solution is the same - screen reboot. If this isn't the case, it will remain frozen, even if the computer is turned on or awakened.

  These produce both DP and DVI ports. My video card is Gigabyte GTX 670 2 GB. I don't have any of these problems with my previous screen using the same PC.

  I would appreciate a response to a Dell employee. Can it be fixed with a firmware update? The update can be done at home? I'm more or less a power user. If this isn't the case, I can get the monitor serviced by an authorized dealer (in Sofia, Bulgaria) with a cover letter or notification by email from Dell. Because as I said there is a good chance I will be denied a replacement of a work apparently monitor. Warranty service is not a strong point here, unfortunately.

  Can it be fixed with a firmware update?
  * Unknown. Try to test with DisplayPort 1.2 disabled on the OSD (On Screen Display)
  * Computer Gigabyte GTX 670 DP--> Dell DP to the CDM cable--> U2913WM CDM in
  * Support on the selection of input Source key
  * Put out Mini DisplayPort
  * Press and hold the green check mark for 8 seconds
  Disable the DisplayPort 1.2
  Out of the OSD

  The update can be done at home?
  * No. Pour get a monitor with the latest firmware, you must launch Dell monitor Exchange.

  If this isn't the case, I can get the monitor serviced by an authorized dealer (in Sofia, Bulgaria) with a cover letter or notification by email from Dell.
  * No. we do not repair the monitors on the ground, simply replace us them.

• Lost emails from Macbook Pro to turn off the iCloud

  MacBook Pro, Macbook and iPhone SE connected to iCloud for the explicit reason for the password in the Keychain Access to the iPhone.

  After turning off on the Macbook Pro, all iCloud email on this computer has disappeared. When you try to sign on oCloud it was indeed a waring on the loss of data, but supposed it meant things that had been transferred to iCloud.

  How is it possible that iCloud can remove data from my hard drive? Is - this intentional?

  Your mail will disappear if you switch off your iCloud. They are serious when they say the loss of data.

• MacBook Pro automatically turning off Wifi; Can't go back

  Hello world

  I have a brand new MacBook Pro. Specs below:

  El Capitan 10.11.3

  MacBook Pro (retina, 13 inches, early 2015)

  Processor: Intel Core i5 at 2.9 GHz

  Memory: 16 GB 1867 MHz DDR3

  Graphics card: Intel Graphics Iris 6100 1536 MB

  I use WiFi when all of a sudden it will slow down my speed to a crawl, then * poof * my WiFi turns off by itself.  I try to go on the menu at the top right to reactivate it, not good. I try to go to system preferences / network to try to turn it back on, even when not go.  I tried to turn off other connections, I tried to add a new location with custom DNS settings (as I read in some articles, such as http://osxdaily.com/2015/10/16/fix-wi-fi-problems-mac-os-x-el-capitan/).  None of that worked, the only way that I can not even WiFi to turn back is to restart my machine.

  Elsewhere on this forum that I read that this could be a problem to upgrade, but since this is a brand new machine I don't think that applies to me.  Needless to say that this is a very frustrating issue, and I have yet to see real solutions.  I know other people have experienced the same problem, but has anyone had any solve positive results?   Any help would be appreciated.

  Thank you

• HP Pavilion beats: HP pavillion beats screen turns off randomly

  So, this Christmas I was very happy to get this laptop and it costs $600. Overall, this is a laptop in circulation, in the way that the graphics could be better and the sound quality of the speakers is not as good as I expected to be. Anyway, back to my question. I was using the laptop computer throughout the day, and so far, everything works normally. However, sometimes, randomly; without notice, the screen goes black and it's basically freezing. This happened only once while I was typing and once when I was watching a video. I have been active both times where it turns off and the battery died never imminent when it does. When the screen is frozen, I can't do anything with it; just turn it off. And to give you closure, I tried to turn on/off; the backlit keyboard no changes whatsoever and I also tried pressing the caps lock shift key to find a frequency; and, as only presumed, no led light, nothing. As I said, when these breaks occur, I am very active and the battery is charged. If it helps, I did not experience WHILE the laptop was in charge. It's a shame that this one portable grand has a simple flaw that could probably be easily resolved.

  Thanks for listening,

  Martine

  You are a gift from heaven. Very useful information. Thank you so much.

  Which brings me to my last question; It is mentioned in the document, restart manually the computer with the power button when the shutdowns occur due to overheating, cannot present the image on the screen, etc. I was wondering if manually restart the PC this manner likely to all damage or damage the PC to be slower in the future.

  Thank you very much for your help!

• MacBook Pro screen turned white rose areas

  I use a Macbook 2009 end Pro 15 ", 4 GB of ram, 2.8 GHz Intel Core 2 Duo. Everything is fully updated. Yesterday, I started getting intermittent flashes of rose on the white areas of the screen. Affected programs were Pages (old and new versions), Safari, Mail, numbers and Quickverse. I have tried a reboot and everything seemed fine, but he reappeared briefly to the waking from sleep.

  Today the same programmes on each screen, including white ares of my desktop image. I can read the material, but it's distracting. The best way I can describe the pink areas are thin vertical lines as fabric. The area directly below the words is mainly white.

  I searched the forums and tried to reset the Pram and go through all the steps for the MSC. I started using the safe, but the rose remained. I ran the disc with no found error utilities. I tried to run the apple hardware test, but nothing happened. [The instructions said close then turn on by holding down the button D. I tried 3 times, but the icon never appeared].

  I also tried 8 Tech tool for video and nothing was found.

  The Apple store nearest is 3 hours away if I'd rather solve this problem without going there.

  Hello

  Looks like your machine is overheated. Maybe there are little dust in the cooling rack. Try to clean it up, then it should work again.

  Good bye

• Equium A200 - screen turns off

  Hi, I'm having a problem with my Toshiba laptop, the screen turns off randomly and the computer still seems to work, but when I use a VGA cable to connect to a TV it does not display anything.

  Here are pictures of when it fires
  http://Tinypic.com/r/vr9d7d/7 yellow on the disc tray is turned on
  http://Tinypic.com/r/2d9poya/7 that the front turned on lights and computer sounds like its operation.

  This led me to believe it's a hardware problem, but when I turn on the computer in Mode safe it never turns off. I also got the fixed ups this year because the screen was losing power.

  Can anyone help I can't really afford a new laptop at the moment

  Hi David,

  It's a little confusing, it doesn't always happen when you shut down the computer, or just sometimes?
  What do you do to get rid of this? Always remove the battery and the AC adapter or what exactly?

  I think that it s a hardware malfunction, usually has nothing to do with the software. What you can try is a BIOS update from the official website of Toshiba.

• Satellite A30-414 turn off randomly

  Hi, I'm new here. I own this Satellite A30-414. It works well, but it turns off randomly. I explain.

  I might use it for non-stop days, it works well, but sometimes it empties and turns off. Then it always turns on the second attempt. I mean, after the stop, I turn it on, I see the MESSAGE, then it turns off again. The second time I turn it on it goes OK and starts Windows XP Pro SP3. There is no particular action, I do it turns off, it can happen any application at any time. As I said, it can stay for days, connected to the internet via wifi or lan, download P2P stuff, no problem not turn off.

  I thought it was the temperature because it's warm enough, so I run it on a laptop computer have lower airflow, not at all, it turns off randomly anyway. Maybe I'm thniking more heating unsoldered some brazing under BGA chips, so it might need a redistribution of some chips, maybe the graphics chip

  Can you help me please?

  Thanx

  Hi satiropan,

  > I thought it was the temperature because it's warm enough, so I run it on a laptop computer have lower airflow, not at all, it turns off randomly anyway.
  Such an external Notebook Cooler will not help you solve this problem. The internal cooling fan is designed and tested for this laptop and everything will work perfectly even on high usage. External cooling is not necessary.

  It's old enough laptop model, so I imagine that a lot of dust blocking the cooling fan. Therefore, clean it with a jet of compressed air to blow the dust from the cooling fans. The exact procedure is described here:

  I hope that it helps :)

• Satellite A210 - 17L - screen turns off

  Hello people,

  I have a similar problem to [http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=61255&tstart=15], screen turns off by itself randomly, but backlight remains lit and laptop always seems to work (judging by fan). This started after upgrading Vista to Windows 7 (new installation), there was no problem before. I tried to update the display driver, first ATI Catalyst, then Toshiba official one, the customer pays less often, but still doesn't work, it's nice embarrassing ;) It occurs regardless if the laptop is used or just slowed down and is not caused by overheating or saving energy, also cell is generally connected with mounted battery.

  I have the last opportunity to go and update the BIOS, but I'm in fear of bricking the thing, so he would try as a last resort.

  Any idea guys?

  Thank you

  Hello

  There is an easy way to solve this problem: connect an external monitor and check what happens. If everything is ok on the external monitor installation (Windows) and internal monitor are ok, the problem must be internal monitor itself.

  If it s the monitor itself it s inverter FL, LCD cable or LCD itself. That s is not easy to say on this virtual path for your laptop needs to be checked to an authorized service provider. Guys can make an accurate diagnosis.

• Equium A210-17I turn off randomly

  Hello

  My laptop is a little more than two years now. Since just after Christmas there now randomly turned off itself several times. Basically the screen turns off, standby-led is orange regular and the hard drive light flashes very quickly. Even when it is plugged in, the cord and battery supply turns off lights. To re - start the computer, I have to turn the power off then remove the battery and it starts normally after that (usually propose a SafeMode as a startup option).

  Sometimes the laptop was warm enough, but the last time he did not feel too (and comes to be browsing the internet). The first, some times even if I had just watched a DVD / was something the iplayer streaming and it was nice and warm. I ordered a cooling with built-in fans support where it is overheating, but it happened when on my knees too, so I'm really not block all of the fans.

  I just thought that I would ask here in case the lights were any sort of way to identify the problem, or if anyone else had a similar problem. As I say it still works well most of the time and it only did about 5 or 6 times in the last month and a half, but I'm worried still cause problems and so would work it out!

  Any help much appreciated!

  Hello

  If you have the replaced cooling fans, but have you also renewed the thermal grease? This should also be done sometimes and if your laptop is still 2 years old, it could be the problem of this stop randomly.
  Check this box!

  Otherwise, I think that he associated material s and maybe the motherboard, CPU, or RAM is the cause but your laptop should be checked by a technician of the laptop.

• Two problems that seem to be related. The screen turns off suddenly and reappears when the mouse is clicked. At the same time, the cursor insertion point disappears.

  The cursor disappears during the strike. It is blackened and cursor disappeared three times during the typing of this sentence. Very frustrating! I'm running Windows 7 Pro on a Dell Inspiron.

  Hi Ed,

  Thanks for posting your question in the Microsoft community.

  I understand that you have 2 problems on your Windows 7 computer.

  1. The screen turns off when you click with the mouse.
  2. The cursor on the screen disappears while typing.

  Let me know if this interpretation is erroneous. To better understand the issue, let me ask a few questions.

  1. What is the brand and model of the computer?
  2. You did changes to the computer before the show?

  I am here to help you and I suggest these methods to solve the problem.

  Method 1:

  Start the computer in safe mode and check if the same problems occur. Safe mode allows only a minimum set of services to load, this will help us to know if a service is causing the problem.

  Startup options (including safe mode)
  http://Windows.Microsoft.com/en-us/Windows7/advanced-startup-options-including-safe-mode

  Method 2:

  If the problem does not occur in safe mode, and then perform a clean boot, this will turn off non-Microsoft services and therefore to determine if any non-Microsoft service is causing a conflict for the problem to occur.

  Note: once the diagnosis is made, follow the steps in the article to configure the computer to start the Normal start.

  Method 3:

  The question could have occurred because the drivers on your computers are not updated. See the link, follow the steps and update the drivers.

• Inspiron 9300 screen turns off after the Windows Logo screen

  Inspiron 9300 my wife became severely infected.  I thought I had some weird things start popping up of the problem decided to wipe the hard drive and start over.  Unfortunately, I don't have to restore disks when I bought the computer.  I install windows xp pro service pack 2 full retail version.

  Installation was not a problem until I installed the driver ATI Mobility x 300.  I followed directions for installation from the website, do the installation of xp followed of the dell system software update followed of chipset followed video driver.  After that whenever I put on, the screen turns off after the Windows Logo.  The computer is still running and if I plug an external monitor everythng is fine.

  I tried all the troubleshooting tips I've seen in this forum.  I did a full install twice. made of safety boots (all right), started in VGA mode (works fine), I ran diagnostics from fn on startup, including express, extended and video tests and they pass all the controls.  I'm sure it's a software problem, but have been unable to solve.  I've updated the ATI bios although when I run it says already installed and done one installs x 300 driver on 6 ttimes own.

  I know it must be something simple that I'm missing. My system is the Inspiron 9300 with 2 GB of ram and the mobility x 300 card.  Any help would be appreciated.
