Black screen before chime

Hi,
It started to take longer time before chime is heard. The screen stays black after power up and then the screen stays black more that it used to be. I wonder what may be the cause?.

If it is a fairly new Mac mini and under warranty I would call Apple Care just to get the issue into the data base for your serial number. More than once, especially close to the end of the warranty, Apple Care has asked why I delayed on an issue and why they had no notations of earlier occurrences in their records. So I make sure that they know about everything now and I get a case number. Usually nothing comes of the issue, but at least I have covered the bases.

Dell Latitude E6510 Black screen before posting during cold boot

When I cold boot my laptop,I get about 10sec of black screen before the laptop posts..1st gen. i5 core,4gb DDR3 80GB Intel X25-M Nvidia NVS 3100 graphics with 512MB RAM.

I received a new XPS13 9343 last week and unpacked it yesterday (Friday 4/24/2015). When I first opened the lid and powered it up there was no display. It was completely black, not blank. I went to close the lid and when slightly jarring it I noticed that the initial screen appeared but briefly.
After analyzing the symptom I decided:
It is a physical issue - not firmware related
While I apply very slight pressure compressing the lower right corner of the display it will function
It is the LCD backlight that is intermittent as the image is perfect otherwise and turns on an off with pressure not quite instantaneously
Once the laptop warms (2 minutes) the display becomes completely reliable and unaffected by lid motion
My bet is that this is a problem with the conductive rubber mounting strip used to make the many connections to the LCD panel. Envision a very thin foam double sided tape with the characteristic that current can only flow front to back through the thin dimension of the tape. Adjacent pads (connection points) are not shorted by the tape and pads (carefully) aligned on the other side of the tape are connected. Its very ingenious actually.
In my case probably the circuit for the LCD backlight is at the end of a strip on the bottom right. It didn't properly bond during production. Probably once current flows through it (when I compress the display or hold the lid in just the right position) the adhesive warms and grabs hold. It probably doesn't take much to pass the low currents involved. I wonder if after some use or exposure to warmer operating conditions if it might not finally bond permanently and the issue go away?
Anyway this is what happens when you present an engineer with a problem, it gets over analyzed. You would like to think that within hours of posting this a bunch of production engineers will run over to all of the fixtures in their facilities that are used to assemble the displays and make sure there isn't one out of adjustment. Uneven clamping force or some such science.
The problem now for me is in finding out if I need to replace it and how much of a pain that is going to be. Unfortunately now I don't want to migrate from my prior laptop if I am going to have to send this one off someplace.
In some way this represents a security feature. Haha. I mean there is a trick to getting the thing to come up that I would only know. Another level of security at no extra charge. Still, one wishes to not have a quality concern floating in the back of your mind.
But, this might be your issue too. Anyone else have this experience?

TS1702 Downloaded Air Supremacy game app and only get company logo or black screen before iPad returns to home screen. Checked iPad and app up to date, no better. Any suggestions?

Downloaded Air Supremacy game app and only get company logo or a black screen before the app closes and goes back to my home screen. Checked that iPad and game are latest versions of software and restarted the iPad still with no luck. Any suggestions.

Have you tried a Reset...
Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears. Release the Buttons.

Macbook pro (early 2011) won't boot after sleep. Black screen with chime

I put my macbook pro early 2011 (Quad, 8 Gb RAM, 2 x SSD-disks, external 27" LED-screen) into sleep mode a couple of days ago. Everything was fine then.
However, the morning after it wouldn't wake up - this is the bootup process:
- Black screen
- Chime
- Still black screen, nothing happens.
So I've tried resetting NVRAM, SMC etc - no luck. Even tried the "Powerbutton" + "S" + Enter but to no avail.So I immediately began dd:ing my SSD-disk before trying anything else, figured it might be some preboot-corruption of some sort since I'm running FileVault2 with full AES-encryption.
Now, the problem (after some troubleshooting) doesn't seem to be disk-oriented. Remember the black screen? I've tried pulling the SATA-cables one by one on the motherboard of the Macbook pro and discovered that when I pulled the cable which reaches over the optical device (just above the SATA-cable for the optical device) then I get a white screen and I'm able to get as far as boot-option, or even disk repair (if I run my SSD-disk over USB and without any cables (three of them) attacked to the motherboard).
So since nothing works when I have disks connected or that third cable (some kind of logic board bridge? Reaches through the screen over to the other side of the mother board).
Also worth noting is that I was running out of free disk-space on my system disk. The disk is 250 Gb and free space was about 5-10 Gb (less than 5%). I also make the macbook pro dump contents of memory to disk (since my disk is encrypted it resides safely there).
So, my fear is that Apple hasn't used A-grade controllers for the disk drives (I've had drive corruption before, a Crucial 6 GB/s drive trashed less than a week before a presentation) and doesn't handle "unexpected events" nor signal/noise ratio very well. Maybe free space on disk was less than the 8 Gb needed to dump RAM (shouldn't have needed the full 8 Gb though) and this caused some kind of panic overwrite which trashed the controller?
Anyways, I've attached an image of the motherboard and I am wondering - what does the top cable which reaches over the optical drive do? Is it connected to the logic-board?

Looks to me like a fatal error on the hard disk. IMHO, the only solution is to boot from an external device, reformat the hard drive, and restore from backup. If you don't have a backup, you're in trouble. Boot from the external device, try to mount the int'l drive, and, if successful, back up as much as possible. Also, try running Disk Utility—it may be possible to fix it while booted from a different device, thought I wouldn't bank on it. At any rate, make sure to run an AHT afterwards, to check for possible hardware issues with the drive.
If the machine is still covered by AppleCare, take it to the store by all means. But they won't try to recover anything from the int'l drive, just check it, erase it if they don't find hardware issues, and re-install a fresh copy of the OS.
That's why you should always have at least 1 up-to-date backup (2, with one kept off-site, is better).

Not fully starting up w/ black screen & no chime

My 15 month old 17" MacBook Pro decided to go to sleep this afternoon and never wake up. Had to hold down the power key to turn it off, but after that point, whenever the power key is pushed, the light immediately comes on in the front and it makes a slight sound (similar to waking from sleep).. no startup chime, and the screen remains black.
I have tried resetting PRAM, Power Reset, changed out ram to the factory stick, and even trying to target disk mode it to my wife's iMac in the hopes I could pull off the most recent data.. to no avail. (wouldn't even show up). I tried to boot from the 10.5 disc and it just got stuck in the machine and wouldnt see it (though I can hear it spinning up in there when I attempt a restart)
I have never seen anything quite like it in my years of dealing with Macs and it has me quite perplexed. I have trolled all the forum posts that include "not starting up" and have tried every trick mentioned. Suspect is the hard drive at this point, but the Logic Board keeps coming up in posts so I am not ruling that out. I have an insurance policy that may cover this but I am trying to revive it before resorting to that (or driving 2 hours to the nearest Apple Store)...
Anyone have any other suggestions? I would try a key on a kite in a lightening storm at this point if I thought it would help (though I suspect that power surges/outages we have had here the last few days are the culprit since it was not even acting any different until a few days ago.. even though I have it on a UPS) Help!

Are you sure the screen is totally black? My Core Duo MBP started up to what I thought was a black screen. when I turned on the overhead lights I could just barely see something on the screen. When I used a bright flashlight I could seee that my desktop was there. The problem was the backlight going out. This is repaired by replacing the inverter.

Black Screen - Get Chime - Can Boot off HDD using another Mac - iMac 24in.

Hope someone can help me here, as I'm at my wits end.
I've got two issues, one with my MacBook Pro 17in, 4GB RAM, 160GB 7200rpm (2008) and another with my iMac 24in. 4GB RAM, 500GB 7200rpm (2009).
Firstly the MBP, left work on Thursday last week, got home, powered up the MBP and got a black screen!!! Tried resetting PRAM, SMC, booting in safe mode, removing and re-installing RAM, removing battery and mains power and leaving off overnight etc etc, yet nothing happens. Benn all over the forums and have not found any solution to get my beloved MBP working on it's own. I can boot off the HDD using another MBP 15in, re-install Snow Leopard and as far as I can tell the HDD is fine, as I have run disk utility and it tells me the HDD is OK.
I can't figure this out and it's doing my head in, as I use this laptop for business use and just can't afford to go out and buy another Mac. I should point out that this MBP never had any issues when running on Leopard, but ever since I upgraded to Snow Leopard, I have had nothing, but trouble. I did a clean install, in fact I have done it at least twice, even erasing the HDD securely, both at 7pass and 35pass, yet I have had permissions issues regularly and on the odd occasion, I have also had the problem of the HDD not being recognised.
The iMac is nearly the same, but the screen is working, although the iMac doesn't see the HDD no matter what way I do, again, reset PRAM, SMC, safe boot etc etc. In truth the iMac has been a lot more unreliable, but with the screen working, if I can get any solutions here, then I'll be working to work on that without the need or hassle of working via another.
I think that the MBP is only just still under warranty, but the iMac definitely is, but I need at least one working for business use, so really only want to let Apple have one at a time to look at/repair etc.
Ideally, as the HDD is working in the MBP, if I could get a solution to the black screen issue, then I could do without the iMac for whatever time it takes, so if there is anyone out there that can help, I'd be so grateful.
One last thing, when I bought the iMac 24in., I also bought an iMac 20in., but I never upgraded the 20in. to Snow Leopard and to this day, it has worked flawlessly, without a single issue ever.
Perhaps, I'm getting paranoid here, but there seems to me to be a link between the ongoing and regularly occurring problems with both Macs ant the upgrade to Snow Leopard. Why also, or is it just pure unadulterated coincidence that both the MBP and the iMac 24in have failed at pretty much the same time??!!!!
I'm going mental here, so I hope someone out there has a better fix, then me overdosing on Prozac!!
PS
I'm not a mac expert, not good with a soldering iron either, but I'm capable of following good instructions.

Using Snow Leopard forum is probably your best bet.
I don't care if someone has 20+ yrs, I still like having a good troubleshooting book/manual handy.
Mac: can't get by without bootable backups, even if you use TimeMachine, clone your system. Save you all this fuss and work.
Then invest in high quality disk repair and maintenance program.
Disk Warrior / TechTool Pro 5 / Drive Genius 3 - top 3 probably
There are always going to be normal items you just ignore with Repair Permissions. Useful to do once in a while but not magic. Same with SMC and the rest. Running disk repair is one of those things that it seems should be done before there is trouble, not after, and a weakness in HFS file system and disk directory.
Apple Support is a good place to start looking and then hardware category.
http://www.apple.com/support
http://www.apple.com/support/imac /macbookpro etc
Make sure all your software is current, don't install anything you are unsure of or can do without.
Run Apple Hardware Test off your OEM DVD specific to the Mac.
Now, have you Googled for this?
have you looked at reports about 500GB drives used in some Macs that had issues and were offered firmware update for the drive?
Considered just using another drive connected to iMac?
You can overheat a hard drive with needlessly running 7 and 35-write pass, besides which the best way to map out bad blocks is not Disk Utility.

I'd direct your replies to iMac and MacBook Pro as well as to Using OS X Snow Leopard areas.

Black screen before Windows installation

I have already installed Windows 7 before and I had no problems with the installation. The reason why I decided to reinstall Windows is when I was trying to start BootCamp I only got black screen. This started to happen after I did hard reboot. I did this because Windows freezed.
I deleted Windows on my MacBook and then I tried to install Windows again. After BootCamp Assistant splited hard drive (1st part for Mac OS X, 2nd part for Windows) OS X shutted down and after that I heard Mac sound (sound when You start Mac). And then I can only see black screen ( also there was a console cursor for a second ).
Why black screen started to happen?
and
How can I avoid it?

Black screen before going to sleep

With the "dim screen..." option box UNCHECKED, instead of dimming the screen before putting the display to sleep, the screen turns black. The same kinda black as if you dim your backlight to 0.
So I can still see some windows etc... but the backlight is just not working.
This is very annoying cause it turns my screen to black after one minute when I am on the battery and it makes it impossible to read a text.
I believe this is a bug... what do you think, o you have the same problem?
PS: Of course my sleep setting is set to a much longer time (15 minutes) so it is not related to that.

Sat A665 - S6092 black screen before windows startup

I got a problem, it is strange. Sometimes windows starts and sometimes it doesnt. I normally press the power button, then it appear toshiba logo, then it appears a little line blinking at the top of the black screen and then it goes completely black, nothing happens. If I press ctrl + alt + del it reboots, but it I press the power button it turns off roughly. Sometimes I reboot 2 times and windows starts, sometimes 10 times and it starts, and sometimes it starts normally. What can I do? Thank you

I have the same problem with my Sat665d for about 1mth. Finally it got worse and worse. Problem is that your hard drive is failing and that you should back up your files asap while you still can. Toshiba is replacing my hard drive. I'm packing my laptop in the box they sent me. It's all prepaid shipping etc. Fed ex is picking it up in the morning. My laptop was under the 1yr manufactures warranty. So i hope yours is under warranty,otherwise you have to pay for new hard drive. They are relatively cheap about $60.00 -$100.00 depending how big it is. I hope this helps you before it's to late.

Mid-2011 iMac - black screen, no chime

My iMac has been working like a charm all the time except a few months back it started to reveal symptoms on each boot. I keep iMac turned on all the time, so it hasn't bothered me much, only on software update when you have to reboot the machine.
Every time I had to boot iMac it hangs on the grey start-up screen with Apple logo and spinning wheel. I can get through it pressing C while booting (C is the key to boot from external device, such as DVD or USB) without having any discs inserted or devices connected. Yesterday I installed the 10.8.4 Combo update and booted with Cmd-V to access the verbose boot mode. I managed to get there 3 times in a row, every time it freezed on the line:
AppleIntelCPUPowerManagement
Two times only partly printed "AppleIntelCPUPowerM". Now I'm stuck with a black screen and no start-up chime. I can hear the fans are spinning slowly and the hard drive and the optical drive both at least get's power. No other marks of life here. Did the SMC reset - nothing. No response on keyboard (tried to boot to safe mode, make a PRAM reset, boot from external device.. everything).
Then I tried to remove all the RAM banks and boot. One beep constantly repeating with a delay of a second which means "No RAM installed". Then I started to put in one bank at a time and some of them got three beeps ("No RAM banks passed memory testing"). Then I started to put multiple banks at the same time, on some booting trials the same RAM bank was resulted as faulty, on some trials as functional.
Based on this information from the verbose boot and the experience with RAM, is it..
a) the power supply (because it froze on AppleIntelCPUPowerManagement)
b) the logic board (same RAM banks are faulty and functional on different boots)
c) OS X kernel (while AppleIntelCPUPowerManagement is a kext)
or something else?
Is there anything I can do? Do I have to take it to the Apple repair service?
If it's the logic board, can I ask for a newer replacement board, let's say, I want to switch the mid-2011 logic board to an early-2013 logic board, is it possible?

Took it to the repair service, it was the logic board that was broken.
With a price tag half of a brand new iMac, I started wondering, do I have any chance of compesation from Apple referring to consumer protection? The iMac was bought on December 2011, so it's only 1½ years old machine - the logic board of this fresh computer is not meant to broke.. At least I think so? Of course the basic warranty is 1 year and I didn't have AppleCare 'cause I bought it used last summer.
I know I'm on a thin ice with this, but this amount of money drives a man to a far-fetched actions.. I even didn't get to break it myself, it just fell apart by itself.. That's just wrong.

Black Screen before installing windows 7. Lets solve once and for all.

I have a late 2008 macbook pro and have been trying to install windows 7 through boot camp for a number of days now. I have read every forum on the internet and have tried every popular solution (i.e. resetting pram, smc, unplugging, changing screen resolution, etc.) and nothing has worked. I know there are many other people with this problem but none of them have solutions. I had windows 7 installed a few months ago but it stopped working and I had to delete it. Just yesterday I reinstalled Snow Leopard and still nothing. I created the partition and tried to install windows but it just goes to the blinking cursor for one second, then a black screen. I have tried everything possible and nothing works.
Please lets try to get this problem solved because out of every single forum on the internet, none of them have solved this problem.

I think after weeks of searching I have finally narrowed it down, based on what I have read, to a disk drive problem. It seems to be something wrong with the EFI or the entire disk drive in general. I am taking it to the apple store tomorrow and I highly doubt they will do anything.

HT4407 Help: Encountered black screen before Windows 7 was installed. .

I encountered black screen in Boot Camp after partition was completed with a character cursor blinked on top left.
How can I fix it and complete Windows 7 installation? Thanks for your kind advice in advance.

Black screen before startup

Hey I've got a hp pavilion dv6 that has just gone down on me. The display just went black and now when I turn it on it just stays black screen, no light at all the screen. I've tried unplugging the battery and AC and holding down the power button for 30-60 seconds. Been trying for 30 minutes now, also tried reseating the memory in the laptop. The caps lock light is on BUT NOT FLASHING. The F12 light is on aswell as the light closest to the cd drive, the 2 lights in either side of the AC plugin is not on. But the AC is working though cause I can tun it on while battery is out and AC is in
Any ideas what the problem might be?
Thanks in advance
Nicklas Ovesen

Hi @ Nicklas4600,
Welcome to the HP Support Forums, Now just to help me out a bit here with your issue.
When you press the power button you get no response except the LED on for the F12 button and on either side of the power connection as well as the optical drive LED. These LED's stay on constant or do any of them flash in any way. As well could you post back with a little more information for me.
1) Is there any fan sound when you press the power button.
2) When the optical drive LED comes on is there any noise coming from the drive.
3) What are the colour of the LED's.
Other information that I will need is your complete model and product number. Here is a link that will show you where to find this information.
Here is a link you can use that will help you find your model and product number for your hp notebook.
How Do I Find My Model Number or Product Number?

Short black screen before play

When I preview my Encore bluray project and push a menu button, the screen goes black for a quarter of a second before the chosen movie begins.
How can I avoid this?

Hunt,
It ws only a preview issue. On the final burn there was no black flash.
I have a question regarding transcoding, don´t know if you can help:
I encode video with Compressor, using a custom preset, MPEG2, 1920x1080 25P which gives me a m2v file.
When importing this file to Encore, the BluRay transcode status shows "Untranscoded", and it looks like the file is transcoded when I build the disc.
Am I right, that the transcode status should show "Don't transcode" if the imported video is correct encoded from Compressor?
Best regards
Bjorn
Den 20/03/2011 kl. 22.18 skrev Bill Hunt:
Welcome to the forum.
Have you done a test Burn to Folder, or Burn to Disc, to check whether it's ONLY an issue in Preview? Preview is but an emulation, and a "black flash" is one of the common drawbacks to testing with it. The "black flashes" seldom appear in the actual file. Note: if you do a Burn to Disc, use RW media, for the test, so you don't burn "coasters." Just do not use the RW for delivery - testing only.
Good luck,
Hunt
