• 2012 MacBook Pro renovated migrated 8/20, screen has blacked out for the second time

  can not force stop with long hold on the power button / stop. The first time was in the second day of use, after all the updates from app store. Screen was back the next morning. 4 GB of ram, mid-2012, os 10.11.6.

  I have the same PBM and had a similar problem. One day I went to turn on my MBP and the screen was black.

  It was seems to be dead. The screen was not lit. I tried the Mini external display port with a television by HDMI cable and adapter screen.

  https://www.Amazon.com/Sabrent-DisplayPort-Thunderbolt-adapter-da-MDHA/DP/B017NK IQ8M/ref = sr_1_5? ie = UTF8 & qid = 1471973756 & sr = 8-5 & keywords = + mini displayport + to + hdmi + 4 k

  And the macbook worked fine with the TV. TV display showed MBP display very well.

  This led me to believe that there is just something wrong with my screen LED on the MBP.

  So I opened the back cover of the MBP and looked inside.

  I saw the cable that connects the screen LED MBP to motherboard and disconnected it and then reinstall it.

  I then closed the MBP and restarted.

  IS!... LED MBP display worked again. If the problem was simply that the cable of the LED screen did not have a good connection. So, just to be disconnected and reconnected to make good contact.

  This maybe off topic but it's worth a try. It may be your screen LED cable which does not have a good contact.

• P2715Q, black flicker for a second, every now and then

  Nice day

  A few months ago I bought the Dell P2715Q, and with some delay, he finally delivered. Well, it appeared the first monitor was broken and had a blue vertical line on the screen. Reference Dell replaced without any trouble, thank you very much for this. However, now with my second P2715Q I got a new problem. Works in 4 k resolution, 3840 x 2160 60 Hz, every now and then the monitor turns black for a second and then it goes back new. It happens randomly, but it seems to happen more often when playing or watching films/series. It happen to rest so so, or only during navigation. It happens sometimes only once in 15 minutes about, sometimes twice or three times in one minute. Oh yes, connected with a cable of DP. So, any idea what could be the problem? Does anyone else have this problem? I'm probably going to soon test the monitor on a friends place, see if my gpu (new) could be causing it, but I doubt it. I had him flickers black on my previous so P2715Q and tested my friends place aswell. There, blacks of ejection happened too.

  The problem has been resolved, it was cable that was the issue. Had a DisplayPort to Clicktronic cable high quality 4K but apparently it wasn't enough good, bought a cable Premium GOLD of Lindy who certified DP1.2 and the problem doesn't happen more.

  It's funny, although considering THAT VESA said in a blog post that it doesn't matter what cable you use, but it is obviously false.

  Also the cable which is included in the box with the monitor at Dell, the DP-> CDM works also, but it is very lose in the connections and the screen lights up and turn it back on as soon as you touch the cable or set the monitor a lack of contact.

• Black screen for 10 seconds and then lock screen after ios 10

  I am facing a problem where my iphone 6 randomly shows a black screen with a loading circle in the Center for about 10 seconds and then wakes up to the password lock screen.

• 372T - Acer R7 R13: screen often goes out for a second and returns back, CORRECT.

  I have power cuts momentary screen, usually while you browse in Chrome/Opera with several tabs open. You also have this kind of disturbing screen blackouts? I really like my R13, but it keeps listening to me that I even think about selling my laptop. I tried the graphics driver update myself, but he says it has been customized by the manufacturer. I would be grateful if you could provide an update to resolve this issue. Thank you.

  I have connected to my TV via HDMI.
  The photo is here.
  Every two minutes the black screen for a seconds fue becames, then the picture comes back.
  It is very annoying when I watch a movie.

  Is there a problem with a hdmi cable or with drivers?

  Is it possible to get this working?

  Thanks for any help

  > Is there a problem with a hdmi cable or with drivers?
  Who knows?  :| I think that you will have to test it.

  You could try to reinstall the HDMI Control Manager. This driver is required for your HDMI controller.
  If the question will always be, I recommend that you test different HDMI cables.

• Firefox 7A of the areas that is blacked out when I scroll over them. I don't know why this is happening, but it makes navigation nearly impossible. A to d/l google chrome on this issue, even after

  Any time is nothing more that he goes out for a second. It happens in the browser window. Status bar, text boxes, refresh button, favorite button, etc. My graphics card is up to date and I have not changed one of my other view options.

• HA elections issues, getting only one agent as master and waiting for the second time

  I am facing a strange question HA.

  Much more kit (2 hosts, vcenter) virtual, DAS storage. VSphere 5.1 latest patches. 1 datacenter, 1 together inside with 2 guests.

  While trying to activate HA (with default settings), an election was held where a master and an error in time-out for the second host. Funny thing is that if I force a new election manually on the two hosts, the first I click to become master, second error timeout showing later.

  The two machines are able to ping the other subnet vmotion and network management subnet.

  I triple check the connections & Configuration of VLAN on the physical switch-> no other success

  I changed vswitch assignment & design in at least 4 different ways-> no other success

  I did break the cluster and datacenter, recreate new-> same question.

  I took both of my hosts (1 at a time) off the VirtualCenter and back in--> no other success

  I do NOT recreate my vCenter (of less not yet...)

  I have NOT reinstall any of my guests from scratch (of less not yet...)

  All constructive ideas?

  There is a kind of strangeness network here. FDM on each host cannot see the election messages sent by the other (on port udp 8182) so each one chooses himself as captain and brand a title "fdmUnreachable". They mark the other as network partitioned because they can ping (using icmp). It's just the udp/TCP traffic 8182 which is not cross.

  _ * History: * _

  Don't know if it's not important, but just to let you know, so interested what happened at the laptop ;)
  I bought the laptop in the form of computers (in the Netherlands) asked that laptop mentioned above, with 2 things have changed. I wanted more memory, and I wanted windows XP. The shop told me it was possible. They bought me the laptop, they replaced with memories of kingston memory. They installed windows XP instead of Vista. They portable worked at that very moment. So, I bought the laptop to work with 1 year warranty.
  With the additional files given with the laptop, I could increase my warranty from 1 to 2 years free, so I did.

  After a few weeks that I noticed that the laptop became real probably hot after prolonged use. But according to the manual, it was normal.
  I used the laptop to the games, but also 2 months for a study of play. So I take several times at school in a backpack.
  After using only not for school, I reinstalled Windows Vista 32 BIT

  When a very uncertain when exactly, I noticed that it does (probably same problem as I have now) but I was really relaxed about, tried subsequently and in some way, it worked again. It happened maybe about 5 times in total.
  Knowing something was wrong, I brought computers to the form. They checked. (No not showing me what they did to her) But he told me that I had nothing to fear.

  After about 2 years, I actually sold this laptop to my mother. She used once or twice (she really looks like noob, just about computers in general, without even knowing if it should double click on the icons or not) she took him one or two times on TRIPS and they after about 2 years and 2 months... this problem happened.

  My mom knows a guy and a friend of this guy, work a lot with laptops broken, who told me that the problem was the motherboard _ + _.

  I decided to take it back to the shop. After a long class being there (about 6 to 8 weeks) (I go to the store like 15 times). The shop was able to tell me it was the motherboard. That the motherboard could not be fixed and a new way to expensive.
  + (I have known at this point, after the motherboard, what this laptop was not open yet. The screws were still new). +
  Funny information (not for me), this period of about 8 weeks, in fact we me lies like... I left a message on your voicemail, I do not HAVE a voicemail... Sorry for the caps, but im still xxxxxx on these lies.

  Therefore still believe in the shop... my laptop has gone... dead... but so since last week, I started looking into the laptop I... (Fixing)

  Hello

  To be honest that s a very long history and I think that we can t help you here and tell you what the problem is exactly because it s just a user to user forum. I think that you need professional help technicians of laptop, they can check what the problem is.

  According to your assignment I think that it s a hardware malfunction, perhaps the card mother, but this should be verified by professional technicians.

  You need to contact a service provider authorized in your country. You can find a list here:

• Satellite C660-1J2 - the screen goes black for a second

  Hey everybody.

  I recently changed my HARD drive and did a reinstall fresh, as previous was damaged. What is happening now is that whenever I have connect or disconnect the cable the screen goes black for a second. There is no real consequence of this, I'd rather just if there was an option to make it happen.

  Then, give a shout someone if you know how to deal with this.

  Hello

  > I have recently changed my HARD drive and did a reinstall of fees
  You have installed Windows from Toshiba normal Microsoft Windows disk or recovery disk?

  To me it sounds like that, you forgot to install the display driver. Also check the Manager of devices for the yellow exclamation points or unknown devices.
  Make sure that correct display driver is installed. You can download the latest version of Toshiba's official website:
