Zero out HD - Black screen?

Hello,
I wanted to do a clean install of Yosemite on my new imac retina 5K.
Some explanations:
At the beginning I copied all my files from my old macbook to the new imac using migrations assistant and it worked. But after some days I decided that I did not need all those files on my new computer and wanted to do a clean install. I downloaded Yosemite from the app store and put it on a usb drive using terminal. Everything worked perfect so far.
Then I rebooted while holding the option key to get to the Startup Manager and selected Yosemite on my usb stick. Then I got to the OS X utility window and chose disk utility. First I erased my main hard drive. After a few seconds it had finished BUT I thought that that was so quick I could also do the zero out erase. So I selected this one and did it again. My Imac told me that it would need one hour to zero out my HD. I did not touch anything and after a few minutes the screen turned black and the computer does not react to my mouse, touchpad or wired keyboard. But I can still hear it work.
Now, 3 hours later, nothing has changed. It seemed like my mac went to sleep because when I touched a key on the keyboard I heard that sound that a mac does when you activate it after sleep, so it starts again. But I still cannot see anything and I do not dare to turn it off.
I also tried searching on the internet but I didn't find anything related/useful.
Specs:
Imac 5K retina late 2014,
Intel Core I7
8 GB RAM
1 TB Fusion Drive
AMD Radeon R9 M295X 4GB GDDR5
I am sorry if there are some grammar mistakes, I am still learning this language.

Well I solved it by restarting the computer. After some research I found that the black screen after sleep is a common problem on macs.

Would like to know if I can connect a macbook pro and link to a PC in any way and still access the macbook pro's files. Display is out/have black screen. I want to back up before I send for repair, but don't own another mac to restart 7.

Is there any way to connect my 2011 macbook pro to my PC laptop (Dell) so that I can get files off of the Mac? The display on the pro is out and I've got a black screen. The computer turns on. Actually it turned on one time after many tries and when I took it the Mac store the guy hit restart before I could stop him. I don't have another Mac to back up files to in restart 7 mode and I can't see my external hard drive to copy to when the computer has no display, so I am at a loss on how to get the files. I would like to get them before I send in for repairs. Any suggestions are appreciated.

The only other thing I can think of is to pull the drive out and hook it to another machine with a USB enclosure. Something like this:
http://www.amazon.com/Vantec-NexStar-2-5-Inch-External-Enclosure/dp/B002JQNXZC/r ef=sr_1_2?ie=UTF8&qid=1388312417&sr=8-2&keywords=2.5+enclosure
Then you could read it like an external USB drive. It's easy to open up and get the drive out.

How do I get my iPhone 5c out of black screen recovery mode?

I have been trying for countless hours and days to get my iPhone 5c out of recovery mode (black screen no apple logo or anything else) the only reason I know it turns on is because the backlight LCD changes color. When I press down on it it leaves a little finger pressure thing. I have tried all of the ways to get it out of DFU mode, Out of Recovery Mode, I have tried restoring it, in which case i get the error 4005,40013 etc. So now I have come here for my last hoorah on trying to get this pile out of recovery mode and the IOS installed and working.
I don't know if this matters or not but, I have recently purchased a screen from ebay, it was an original iPhone screen etc. I have replaced it and as i said the screen works fine. that shouldn't have any problem with the actual software malfunctioning to update, but here is the log! Enjoy!
All help is greatly appreciated and I will do my best to give credit where it is deserved in the future! God Bless!

I ran into the problem you have after trying to update to 7.1.2 the phone updated, but got stuck in recovery mode, and none of the reset methods worked. I did some searching and came up with a simple method, and it got me out of the loop.
Once i used this app, My phone booted and The update was in place.

HT201274 I erase all data and content from my ipad mini, more than 8hrs nothing come out beside black screen and loading. help plz?

How long it takes to finish this reset?

It's taking far too long.
Disconnect and reset.
Hold the Sleep and Home button down until you see the Apple logo.

So this is weird, brightness effected BLACK SCREEN 27" iMac 2010

Huge problem with my iMac - ongoing.
Could not go past 3-4 clicks without the screen cutting out. (BLACK SCREEN)
Computer still runs in background.
I tried everything to fix it.
I fiddled with the RAM a bit and that solved it today - or so I thought.
It seems that at full brightness my desktop is fine, but if I lower it, it blacks out again.
Is this strange? I am rather astonished under the circumstances.
Anyone have an opinion or experience in the matter?
Thanks!

Geraldine - for what it's worth, I've had this problem for over a year now with my FP15" iMac 800mhz. After reading up on it here in these discussion boards after the first time it occurred, I took it in to the local Apple store assuming they would repair it. They were aware of the issue and convinced me to wait until it went black 100% of the time, and then consider repair or replacement. As I said, the problem still pops up from time to time - each time I think, uh-oh here it goes, permanent black. But the display will then quickly come back - sometimes by just moving the mouse.
My iMac will be 6 years old this April and it's used daily. So I'm keeping my fingers crossed, but know it will need replacement some time. I definitely back up my hard drive much more often than in the past. If it does go, I want to be sure I have a mirror image of the HD so I can easily move my data to a new machine.

Qosmio X300 11S, Black Screen.

I have had this laptop for 2 years, besides quite a few overheating problems it has performed well.
In November last year i noticed my games where once again very laggy, a sign i interpreted as time for a full clean, so i sent it off for a service.
The game i mostly play is World of Warcraft, after i received my laptop back from the service i logged into world of Warcraft and played for an hour or so and got my very first black screen, sound was looping, mouse and keyboard unresponsive. It took me at least 5 minutes to shut it down via the power button.
The black screens/crashes just kept happening i checked i had all the latest drivers installed, so i tried rolling them back but the crashes just kept coming. Where as when they first started i could get a couple of hours between them, it was now minutes at best.
To finally rule out a soft wear problem/corrupt file i decided to reinstall windows, after reinstalling windows updating windows drivers etc i then reinstalled wow however it lasted only a few seconds before the black screen/ crash happened again.
So i wiped the hard drive again, this time i have installed nothing but the windows disks, so my laptop is just like it was the day it came out of the box, and i still cant play any game like solitaire with out this black screen/crash happening.
I have an extended warrantee but they refuse to look at it as its a soft wear issue according to there under righters. Any body have any idea ?

so i sent it off for a service.
What did they do? How did they service it?
They just take it apart check the fans are working correctly and give it a clean, removing the dust from the fans and the heat sink..
Did you actually reinstall clean windows versions by truly formatting the hard drive and reinstalling windows and drivers from scratch?
I have the recovery disks i made myself , I boot it and recover it from them.
If you reinstall windows 7 it will create a 100 mb partition and keep the old system files and others in windows old folder, have a look here it might help.
I have windows vista installed and there is a separate partition.
Prior to contacting my extended warrantee, i tried to rule out a soft wear issue. I even made a call to Toshiba Tech support the person i spoke to did a link up to my laptop, as i had mentioned the vista games also caused this crash he had a game of solitaire. This did as i expected, cause me to receive a black screen/ crash. However the person at the other end told me over the phone that when this happened, on his computer it showed my mem and CPU where both running at 100% just prior to seeing the black screen and being disconnected. So i do believe your guess of something being overloaded is correct i just need to be able to prove it.

HT201263 MY IPHONE 5 WILL NOT CHARGE AT ALL AFTER THE BATTERY RAN OUT. ITUNES IS NOT PICKING UP THE IPHONE AND TRIED SEVERAL GENUINE CHARGERS AND STILL IS NOT CHARGING JUST A BLACK SCREEN. THE PHONE HASN`T BEEN DROPPED OR GOT WATER IN IT. IT ONLY 12 MONTH

I have the Iphone 5, it is just over 12 months old, and it was low on charge, by the time I could get to a charger it had cut out. So i plugged it in the charger like no other time, went back after 10mins and noticed the screen was still black. So i tried to turn it on but nothing still black screen, i changed the charger for my other apple charger and the same thing happened. i decided to plug it in using the usb in the computer and still the same thing has happened. Took it to the apple genuis team to be told they can`t do anything, and now its out of its 12 months warranty makes it even more difficult. Has anyone else had this issue, this is my 4th iphone since they released them and am very dissappointed to say the least that the iphone 5 for me seems to have a life span on just over 12 months and no one is prepared to take any responsiblity as i have not damaged it. One extremely dissappointed Iphone user. Any ideas on how to get it working again?

Let the battery fully darain. After charging for an least an hour try a reset and restore. Use Recovery mode if necessary.
If not successful, then time for an appointment at the Genius Bar of an Apple store.

Hi,
I don't think the ISO you downloaded will provide the necessary repair options you need to try, so I'd suggest first creating a retail Vista installation disc and using the repair options this provides. A full description of creating the disc ( including links to the Vista Image downloads ) can be found on the following link.
http://en.community.dell.com/support-forums/software-os/w/microsoft_os/3317.2-3-microsoft-windows-vi...
Once created, tap away at the esc key as you start the notebook to enter the Start-up Menu. Insert the Rescue CD. Select Boot options ( usually f9 ), use the arrow keys to select the CD/DVD drive and hit enter. You may also get a prompt to 'Press any key to continue' - do this if asked.
When loaded, select Repair Your Computer and choose the Command Prompt. When this loads, enter the following commands and hit enter after each one - include spaces as shown.
Bootrec.exe
bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd
bootrec /fixmbr
bootrec /fixboot
Remove the Rescue CD and try rebooting the notebook.

DP-K

I am trying to install Adobe Reader my wife's laptop but "installer" hangs up and fails with a blank black screen. The machine is capable and has a Vista OS. My wife blames the machine and wants to "throw it out." She's an idiot but I need to get this fix

Logging out does not drop me to console but a black screen

Recent pacman -Syu upgraded me to latest xorg-server and I have this problem: logging out does not drop me back to console but a black screen and after 30 seconds, a blinking cursor. Nothing works and I have to reboot. If I choose to reboot (instead of logout) I get the same result except that eventually the computer reboots. Using nv - no problems. Using simple nvidia (single screen) - no problem. (I have a monitor and tv-out setup). Problem remains whether I use xfce4 or fluxbox. And the ctrl-alt-backspace keyboard shortcut results in the same black screen. Xorg.0.log tells me nothing. Before the upgrade, no problem.
I usually use startx and I have ck-launch-session etc in my .xinitrc. I use the latest nvidia-96xx driver and have no other X problem. Everything works, including the tv-out.
This is a minor inconvenience really and I usually switch to a console and as root killall X if I need to log myself out for any reason. But if anyone as a clue as to why this is so, or suffers the same problem, do let me know. Thanks.

Thanks guys...
@ckristi - I don't use kdm. I startx from console when I want to go into X.
@madtux - I guess I will have to read up on kernel mode setting and KMS - I actually don't know what you are referring to although I have seen KMS refered to in this forum with reference to xorg. Any links? Do note no problems with nv and single monitor nvidia. Hopefully the cure is not worse than the disease.

My iPad wont turn on, its black screen then i press home power buttons together and white screen with black apple logo come out after 5 seconds black "lighten" screen comes out and its stuck just like that! Whats the problem?

HI
this happened today suddenly while i was working on my iPad it kicked my out of the app that i was using then white screen with black apple logo came out, i thought it was an ordinary thing cause this happens all the time with me, but this time it refused to turn on! After the white screen with the black logo vanished i wad waiting for my lock screen but no, a black screen showed up just like that! And could tell it was black "lighten" screen i tried more than 10 times to do the home+power thing but it wont work, whats wrong with my ipad!

If the battery is completely drained it may take some time while on the charger before the iPad responds. Plug the iPad into the charger that came with it and plug that into a good wall outlet. Wait one hour. Then reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart. If the iPad restarts let it continue to charge until the battery is 100%. If it doesn't start up make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support. They will examine your iPad and explain your options.

I hope you have a backup if you don't want to lose your iPad contents. You have to restore the iPad now using iTunes on your computer. That's what the message on the screen means.
Take a look at this.

How do I find out what is causing a random black screen on iMac?

Hello I get random black screen on a iMac and I haven't made any hardware changes. How can I find out what is causing this?
Thanks
Jer
iMac 2.66 core 2 duo with Snow Leopard 10.6.8

You can do an SMC and PRAM reset. These won't hurt anything and 'might,' maybe help the screen issue. If it doesn't, then take it into an Apple store or AASP for their guidance and advance testing diagnostics.
SMC:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
PRAM:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

When I am on a call and I come to hang up, the phone which when to my ear has a black screen, starts to light up then blacks out intermittently and in the brief moments it is lit up, the hang up button doesn't work unless I press home or lock buttons firs

When I am on a call and I come to hang up, the phone which when to my ear has a black screen, starts to light up so I can see and click the hang up button, but it then blacks out intermittently and in the brief moments it is lit up, the hang up button doesn't work unless I press the home or lock buttons first

Wow- thanks Jim! I removed the case and voila... it worked. Knock on wood that you solved my problem with such an incredibly simple solution. I'll find out where this proximity sensor is and make sure my case does not interfere with it.
Thanks so much.
