IBook screen stays black at reboot no matter what keys I hold down

Hi, I posted a very similar issue a while back and was able to resolve it with some people's help:
http://discussions.apple.com/message.jspa?messageID=13196227#13196227
This time, I had to force shutdown cause the finder wasn't responding when I was transferring a movie to AppleTV. But now when I try to reboot, the screen stays black no matter what. I've tried booting while holding C, holding the mouse button and alt, but nothing brings me to the boot screen like last time. Similarly, I was low on Gigs, but I had a couple left and was in the process of making room. Would really appreciate any hep. I feel like a moron .

Were you getting warning messages that the hard drive is almost full? You may have corrupted the files on the HD.
Will it boot in Safe Mode? See What is Safe Boot, Safe Mode? (Mac OS X)

Resolve startup issues and perform disk maintenance with Disk Utility and fsck

Imac G4 15" Screen Stays Black After Screen Saver Goes To Sleep

I have an imac G4 15" that I just got from a friend that works pretty well, except that after it goes from the screen saver into to sleep mode, the screen stays black. I can hear the error chimes when I try to awaken the screen with the keys, but the screen just stays black. I have tried to increase the brightness, etc. but to no avail. Eventually I have to resort to re-booting and I am afraid that at some point, either the computer won't reboot or one of my external hard drives will crash. Any advice from someone who has experience with this issue would be greatly appreciated.
THANKS!

HT201263 Iphone4 screen stays black after configuration

Iphone4 failed to respond during normal usage. Therefore I turned off the Iphone4 and restarted the device. Unfortunately the screen of the Iphone stayed black after seeing the apple logo.
As the above didn't resolve the issue, I restarted the Iphone by holding the home and power button. The apple logo appeared again and than the screen stayed black. Although the i-phone is making sounds and you can switch between normal and silend mode.
Than I rebooted the I-phone by using Itunes, and reinstalled a backup, also the screen stayed black after the backup. Although in the beginning you can see the adapter and I tunes logo on the Iphone screen.
Than I rebooted by using Itunes and set up as a new device. I can see the following screen:
After swiping the screens turns black although when I touch the screen I can hear the phone is still working.
How can I resolve this issue?

Call of Duty puts a heavy processing load on several internal components that may be causing them to overheat. I would suggest that you download and install the Free and highly recommended "iStatPro" utility and post the temperature readings that it gives you, around the time that the time that the display goes blank, here in this Forum. (Play the game for quite a while and then check your temps in iStatPro.) That may give us the data we need to diagnose your problem.

Satellite A200 screen stays black when trying to boot

Hello everyone,
My Toshiba Satellite A200 notebook is not working anymore, so everything started when I was playing a game, suddenly, the screen turned blue with some tiny text written on it. I had to hold the power button a few seconds to close it because nothing was happening on the computer. I then pressed the power button to open it. Everthing was going well, until the welcome screen. At this part, it was written "Welcome" but the Vista loading circle left of it wasn't turning.
After a few seconds, I decided to close the computer again, so I did hold the power button so the computer closed. Here is the problem : I tried to reopen it, but the screen stayed black. Nothing was happening. The power light was blue, but not any computer activity. So I let it like that a few minutes then closed it and tried again, but the same thing happened. I tried to disassemble it and noticed one of the two memory card wasn't fully in its slot. I fixed it, but it didn't fix the problem.
I also tried to plug another screen on it, but that one was also black. So I put back the screen on its computer and tried to boot my laptop and it worked. It was booting, but the first problem came back, the Welcome screen was frooze there. So yes I did close it again and then the same thing happened, the screen stayed black.
I don't think the problem is the screen because as I said sometime it goes to the welcome screen. Also I don't hear any welcome sound when the screen stays black as if the computer would simply not start up. And as I said earlier, I don't see any computer activity on the little light in front of the computer. And left of this one, I clearly see that the computer is ON because the power light is blue.
So this is my problem, next time the computer manages to start up I'll try to boot it on the SAFE MODE, but until then, I don't know what to do. Please, help me.
Thanks in advance,
MrRoy
EDIT :
After letting the computer turned off for about 30 minutes, I started it, and booted in safe mode. At this step, I securely closed my comptuer with the shut down button instead on holding the power button. Then I reopened my computer, and it booted and the problem was fixed. Now my notebook is openened and working.
So if this is happening to you :
1. Shut down you computer.
2. Wait for about 30 minutes.
3. Boot in safe mode
4. Shut it down using the shut down button istead off holding the power button.
That should work.

Finally, it doesn't work. I don't know why but my computer did start up after the 30 minutes, but now it's not working anymore. It just won't startup like I said later, with a black screen.
The computer did work for about half an hour. I mean, I managed to start it up but after executing a program, it just froze and I had to hold the power button to restart it. I did it about 3 or 4 times, then it simply did the black screen again. I think the problem is my processor, maybe it's damaged or something, could it be possible?
Because I see that the processor isn't working when I try to start it up.
So let's say it's damaged, would that be the symptoms of my computer?
And if it's the processor, the only way to fix it is to send it to a reparator or something, because I don't feel like it, I'd rather do it myself.
But right now, my computer is simply not booting, like I said in my previous post.
Thanks in advance,
MrRoy

How do i fix my iod touch... screen stays black

how do i fix my iod touch..... the screen stays black with the apple logo then cuts off again after like 5 minutes..... someone please help me ?

Please tell me it's not jailbroken. If it is, all bets are off. It is not...
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

IMac starts with fan, screen stays black

When attempting to start my iMac G5 (Ambient Light Sensor), fans come on but screen stays black. A couple minutes later, the fans rev up and run very quickly and loudly. This started happening when:
1. One day the screen showed a green question mark with a message indicating that the computer needed to be restarted in a box
2. Green lines were all across the screen
3. I forced it to shut down by holding down the power button
4. When I attempted to start it back up the fans started but the screen stayed black
5. After a couple of minutes, the fans revved up
This has been happening ever since. One time the computer started to the desktop but everything was frozen. I have reset the PMU, checked the diagnostic LEDs, reset the PRAM-basically everything suggested. Can anyone help? Thanks!

Start-up problem with my Macbook - light stays on and screen stays black?!

Hi, sometimes when I start up my Macbook the switch-on light stays on and the screen stays black. Then I have to turn it off and when I restart it boots normally. What can this be? I resetted already the PRAM and the firmware is up to date. Perhaps someone understands german. Therefore I added my german post... Many thanks in advance!
Hi, hab ein seltsames Phänomen. Manchmal, vor allem nach ausgeschaltetem Zustand über Nacht, leuchtet nach dem Einschalten das Einschaltlicht auf und geht nicht wieder aus, wie normal wenn das Macbook startet, sondern bleibt an und der Bildschirm bleibt schwarz. Dann schalte ich das Macbook mit dem Ausschaltknof aus und warte ein paar Sekunden und schalte es dann wieder ein. Daraufhin startet es ganz normal. Woran könnte das liegen? Hab schonmal PRAM resettet und die Rechte auch repariert. Der Hardwaretest zeigt auch keine Probleme an. Kann man(n) noch irgendwie überprüfen, woran das liegen könnte oder hat das Problem auch schonmal jemand gehabt? Mein Macbook ist gradmal 2 Monate alt und hat das Problem erst seit kurzem. Könnte das vielleicht auch an einer Software liegen, die ich installiert habe. Kann sowas auch Auswirkungen auf den Bootvorgang haben? Bin Laie und würde gern wissen, ob sowas auch an der Pufferbatterie oder einer kalten Lötstelle liegen kann oder könnte das Macbook da dann gar nicht starten. Wäre für jeden Vorschlag dankbar... Vielen Dank schonmal im voraus!

Hi,
put me on the list as well. I was already in contact with ADC and it seems to me that they acknowledged it as a bug. I'm using a Mini-DVI-to-VGA adapter. And sporadically when unplugging it the internal display stays black or switches to the blue background and hangs there.
As I heard from friends who are using the Mini-DVI-to-DVI adapter in the same use case, this doesn't happen to them.

IMac's screen stays black

Went to wake up my iMac, heard the computer running but screen stayed black. I've tried restarting and unplugging and re-starting with no change. Any other suggestions?

If you don't know what a RAM disk is then you're almost certainly not using it. This was a feature in OS 9 to use RAM as very quick disk storage space. It was not enabled by default. Unless you've created a RAM disk (on Apple Menu > Control Panel > Memory) and saved files to it, you're safe).
Take care only to reset the PMU once.
You should probably start a new thread so you get more attention to your issue.

Try a #1 SMC Reset and see the Apple links, if that doesn't work make a appointment for a evaluation.

- Charge the iPod for half an hour. Then reset the iPod:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- if still not working, connect to your computer. If iTunes sees the iPod, restore the iPod.
- If still problem, place the iPod in recovery mode and then try to restore the iPod. For recovery mod see:

"If VoiceOver is on and the screen is black, but you can still use the device by pressing volume up and volume down, you may have screen curtain on. Try triple-tapping using three fingers on the device display to turn off screen curtain. Or connect the device to iTunes"
