Intel Mac :: Can't Seem To Safe Start Because Screen Remains Black
Jun 28, 2012
I have a 2009-2010 27inch iMac with OSX and software fully updated.My Mac started shutting down or going into deep sleep when left on.I've tried rebooting, power long hold, checking cords etc.I've attempted the 5 second hold after disconnecting the power cord, plugging back in and start no luck.I hear a very small click inside when I long hold, sometimes a very faint spinning sound but nothing else.The fan came on once after a start attempt but nothing else happened. I can't seem to safe start because the screen remains black.
My iBook will not display anything on its screen. Rather, it just remains black. One time, the screen did come on, but then shortly after booting, it flickered a lot and then went black again. A year ago, something similiar happened and when I took it to be serviced (when I had AppleCare), they had to send it away and have a new logic board installed. Now this machine is out of warrenty and and I am not sure what to do, or even if it is the same problem. Any suggestions?? Thanks!
I was browsing the internet, not doing anything major, put the computer to sleep, came back 10 minutes later... black screen. I messed with it for an hour or so and determined that the video card went bad (I'm guessing. It's a mid 2007 macbook pro with the nvidia geforce 8600m. My secondary monitor remains black as well). In the midst of totally freaking out, I decided to activate the voiceover utility, enable screen sharing (after figuring out a slew of keyboard commands I didn't know about), and logged in from my girlfriends computer.
I immediately closed all the windows and applications that I had inadvertently opened during the blind wtf session, and opened up system profiler to see if it is recognizing a video card. Well, it is! It's listing the video card as a GMA x3100! Is there a secondary card in there? Cause if there is, it's not working either. Or is that just a default they would put in if it doesn't recognize a video card? Doesn't seem likely. Or, because I'm using screen sharing, is it picking up my girlfriends card? It's not, because she's using a GMA 950. Maybe it's splitting the difference?
I have a problem: when I restart my Early 2008 MacBook Pro there is no "chime" and the screen remains black. The keyboard doesn't light up or respond to any input, and worse still, the "lid button" light on the front of the notebook remains illuminated, it doesn't blink, it just stays on, shining in my face. I loaded a CD into the optical drive to see if I could use the keyboard to eject it, but this test failed. Now, when I turn on my MBP, I hear the optical drive spinning and the quiet whirr of the fan inside.
I looked on Apple's support website about what to do when a Mac refuses to boot. I tried all of the methods they listed, but since my Mac doesn't respond to keyboard input, all of the techniques failed. Having exhausted everything I could think of, I decided to post here hoping someone could suggest something. I was just on the verge of completing my portfolio website and I would like to salvage my data at least.
When I open my macbook, the screen remains black (as though it's in sleep mode). Adjusting the brightness always fixes this problem, but this is a temporary fix. The brightness is not at zero when I adjust it after opening, often I need to dim the screen to reactivate it. †
This problem is not: related to *clamshell mode*related to unintentionally dimming the screen. related to any of the settings in the Energy Saving panel in system preferences†
Extra info: The computer seems as though it doesn't actually enter sleep mode when I close the computer.I don't think there are any processes running that would prevent sleep mode. I really just want the computer to go to sleep properly when I close the screen and more importantly, that it wake-up when opened, or at least when a button is pushed aside from the brightness buttons.
I'm getting the gray screen when I startup.†I tried using the install disc to repair the utility, but it said it cannot be repaired. I had to use a plug-in mouse instead of my normal wireless mouse to get the startup disc out on a restart. I want to now startup in safe mode, but holding down shift during startup with my wireless keyboard doesn't work. Do I need to have a plug-in type keyboard for this function to work? Can you backup files using safemode?
I have had my g4 for about two years and all of a sudden the thing decided that it's not going to turn on anymore. Power is getting to the machine and a certain amount of whirring is heard but not the signature! as it starts. The screen remains blank and would stay like that all night if I let it. The only thing I did differently before this appeared was to take it to work in a different bag a few times. Rucksack before, Side bag (more vibration).
When I press the start button the screen goes on and I hear the chime but after 2 to 3 seconds the screen goes completely black. the fan in working the red light under the mouse is on. led # 1,2,3 are all on. I can't find my original system disk, so I inserted an original system disk from my macbook and tried pressing "C" at start up. But what ever I do the screen goes on for 2 or 3 second and after that goes black and stays black.
This morning, I synced my iPod with my MacBook and upon completion and permission to disconnect the device, I pulled out the USB cord. At that point the computer instantly turned itself off, and when I hit the power button, I could hear the system trying to start up, but the screen remained black and the sleep light glowed continuously. I unplugged the charger, took out the battery and put it back in, and tried all the troubleshooting tips under the Apple Support guide with no success. I also discovered that when I closed the laptop while it was "on," it would seem to boot up a little more before returning to the black screen. I left it alone for a few hours, and when I tried again to turn it on, it booted up normally and as I was searching for updates, it shut down again as it had earlier.
Does anyone have anything for me to try? I don't want to have to take it into a shop because I can just barely afford to, but I need this computer! Any suggestions would be greatly appreciated :-)
My MacBook is making the startup sound but goes straight to a black/dark grey screen. In other words you can see the screen switching on but it's blank. It's in charge mode, has no other external peripherals attached and it's updated to most recent OSX Yosemite.
I only purchased it in May of this year (refurbished). I have tried booting in to safe mode but again the screen remains the same. ¬†
I woke up this morning and my iMac G5 (w/ Leopard) was frozen. I restarted it manually, but it would freeze on a blue screen without loading the OS. It can start up fine in safe mode, but that's it! I've tried repairing permissions and zapping the PRAM - any other ideas?
What can I do in Safe Mode that might fix my comp? I haven't recently installed any applications, and I have all "open at login" items turned off.
Did a Shift - Command-V and the black screen showing all the startup steps appeared and it all looked good except: AFL Alart Sockwed cant update and INIT Reboot transmit failed. All else looks good. I have tried this 3 times and never go past that point. Then the screen turns off white like it does when it starts normally before the apple appears and the last time the screen went black. †
I have tried starting with just the Shift Key and computer starts up but not in safe mode. I have tired starting with the OS X disk and the C key and it will not recognize the disk.I used the #1 disk since the instructions are printed on the disk. Did not work so I tried disk 2 and I get a menu to start the OS or tools. If I click on either one the screen goes white and stays that way.
computer starts fine and provides a login window, and then the desktop screen with screen saver pictures in perfect color. As it goes through starting programs it starts the same programs that is had open when the computer originally crashed. Even when I close them, before it locks up again, and I am forced to restart the same programs open up to the same place. Its like the computer is frozen in one location and will not go beyond that point. Eventually the screen turns white and sometimes black and sometimes gray.
Tech support thought it was the video card, put a new one in but did not fix the problem and then said it was not that but that it was the monitor. I said that did not make sense since the monitor and desktop icons and pictures are beautiful and clear. They then said it was the inverter board on the monitor and Apple only replace the whole thing. I purchased an inverter board and replace it. No change. The tech person said that the computer works find without the monitor connected - I will see if that is correct next. Isn't that a more systimatic testing procedure then trying parts to see if it works? Oh I did do the complete long hardware test. Took about an hour and it passed! Isn't this strange?
My iMac G5 froze. I restarted it manually, but it kept freezing on a blue screen without loading the OS. It can start up fine in safe mode, but that's it! I've tried repairing permissions and zapping the PRAM. Finally I resorted to an Archive & Install. That didn't work so I did a clean install but that didn't help either. After having done everything under the sun to it to get it to work, it will still only start up in safe mode. I even tried starting up off each of my two external fire wire drives with no luck (it froze on the fire wire screen with both drives - a Maxtor and a Western Digital). I am thinking that something on the mother board has died so that normal booting is prevented but safe mode booting is allowed.
My 2008 Mac Pro display remains black after start up.¬† It is plugged in properly and the light comes on, but the screen stays black.¬† It first started doing this about a week ago, but after a manual restart or two, it would start up properly with the display working.¬† Today the display has remained black every time I've tried to start up.¬†
When I start my computer up in the morning everything else starts normally. First the light comes on on the front of the computer and on the bottom of the monitor, then the start up tone rings and the computer is fully running. But my monitor is black and I do not get the apple picture or nothing on the screen. I thought my monitor was going out, but we have another work station the same and I switched the monitors (same 27" cinema screen as mine). I can actually use the other computer and network into my computer and fully use everything on my computer. But my monitor is black (no display)! I have contacted MAC and have reset the PMU button many times and sometimes this works, but most of the time it does not. I just keep restarting the computer and finally it will start up normally with the display and everything.

After searching the mac forums for a while, it seems like no one else has experienced this problem. All similar problems with black screens occurred during Windows installation, not once it had been installed.
Here's my problem:
I installed boot camp just fine, no problems. Hold option key on startup, and I get 2 options: Macintosh HD and Windows. When I selected Windows for the first few days, it would load up, no problem, and I would be able to run Windows XP.
However, all of a sudden (i.e. didn't download or install anything on either partition that would mess things up) when I select the Windows partition at start up, it goes to a black screen (I don't even see the windows startup logo), and stays like that until I hit the power button on my mac pro tower.
I'm not sure if it matters, but during this black screen process, my keyboard is non responsive.
I attemped to download windows 7 into my macbook pro last night, didn't end up finishing the download due to a few problems. Now when I try to start up my computer it goes to the white screen first, than to a black screen where a little "¬† _¬† "flashes. how to get it to boot up in Mac OS? I'm using the newest installation of lion.
After moving I setup the Mini, but got nothing from the monitor. Reset PRAM & PMU, nothing. CPU chimes, etc.work, but the only thing I get from the monitor is a yellow square with a brief message indicating there's no signal.
It's a Mini, 2 MB RAM, Core 2, OSX10.5.x, it's less than a year old. The CPU appears to be OK. Monitor is getting power.
I have a MacBook Pro 2.33 GHz Intel Core 2 Duo, running Tiger 10.4.11. It has an issue where it takes a LOT of tries (10 - 20 tries) to get it to start up. When I hit the power button, it will turn on, the hard drive spins, the fans go, the usb ports work (I had a laptop cooler hooked up to it that would spin when I turned the computer power on), BUT the screen stays black, no chime. If I keep trying, by holding the power button down for 10 seconds and then hitting it again, it will usually start up on the 10th or 15th or so try.
I've tried varying amounts of time between tries, five minutes, ten minutes, overnight, etc. I haven't done any recent software or hardware updates. Once the computer starts up, it works just fine, aside from running quite hot (typically 60+ sometimes up to 80+C when I'm running photoshop or illustrator).
