Black screens at startup and sleep wakeup

In both 10.5.7, 10.5.8 and now continuing with Snow Leopard, I am getting black screens when I boot. I first noticed this behavior upon waking from sleep in the morning. If I schedule the machine to sleep, it's very likely to not turn the monitor on when it wakes up. The machine is alive, I can ssh to it, etc., but the monitor is dead. All I know to do is reboot by holding the power key down. Upon reboot, I often get the black screen again once or twice. All this forced rebooting cannot be good for my filesystem. I'm suspecting hardware. I guess I need to get a good reproducer and take it to the "geniuses" at apple, no? Any suggestions for troubleshooting this?

Forgot to mention this is on my Intel Mac Pro desktop at home. I have three macs and an iPhone. Apple *****.

That doesn't appear to be a US model, and this is the forums for Toshiba USA. You may want to contact Toshiba in your region.
If it's a European model, you could check the Toshiba Europe forums.

Equium A100 black screen on startup

Toshiba Equium A100 laptop
Completely black screen on startup so please don't say go into safe mode etc, because I can't.
I can't see a thing.
Like once in every 100 goes it will come on and I can F12 to boot from the format disk but it eventually freezes before completion.
Video showing what's happening - BTW the buttons you see me pressing are Fn+F5 I've heard that that sometimes works, but yeah, it didn't.

Thanks.

Hi
Look not good dude I think its an serious hardware issue
I checked the movie and cannot hear a beep when the notebook passes the POST (power on self-test). So for me it looks like something wrong with the hardware
But did you try to connect an external monitor in order to check if something would be visible on second screen? Check this
You could also try this:
Disconnect AC adaptor, remove the battery, wait some time (3-5 hours), then connect both parts and try to power up the notebook. If this fails, well in such case have no many other ideas. Ohhh wait maybe you could check the RAM modules. Try to power up the notebook using one module in each slot

A place to start might be this article:

It's also possible that you have the NVIDIA problem:

If you can't get it working following the steps in the first article, you can contact Apple regarding the NVIDIA repair program.
Good luck!

Black screen on startup early 2008 macbook pro

I am very disappointed with Apple right now. My early-2008 15 inch macbook pro shows a blank/black screen on startup. The hd runs fine and I can dim and undim the backlight on the screen but it stays black/blank.
I talked to an Apple rep and she told me that it was probably my graphics card (which I asked her specifically about when I researched and found many other people like myself with the same issue and then the lawsuit that came as a result). Of course, Apple no longer replaces the graphics card (like a true business person would) as of December 2012 even though they know the cards in the macbooks pros are defective. The Apple rep told me that I would have to take it in to a Apple tech to get it "officially" diagnosed as the graphics card being bad (which would cost me @$150 just for it to be looked at!) and then I would probably still have to pay for the repair!
Of course this happened in the middle of the week while I was in the middle of working on a sermon and other presentation projects. So I had to do my best to try to work from scratch without access to the info on my hd because the graphics card is defective.
Apple, you know the card is defective so please just replace the card! I'm not asking for any perks or upgrades! Just to be able to use my Macbook Pro that, up until now, I have been bragging about and telling everyone how happy I was to switch over from windows!
HELP!! HELP!! HELP!! HELP!!

If you experience distorted video or no video . . . take your affected product to an Apple Authorized Service Provider or Apple Retail Store to determine which service and support options are available. If you plan to visit an Apple Retail store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/
No, it has not cost anything in the past.
Note: as of Dec 7th 2012, it is unlikely products qualify for this extended repair coverage.
That does not mean it's an automatic "no."

You are in Recovery Mode. Follow the instructions below to recover your iPad.
1. Disconnect the USB cable from the device, but leave the other end of the cable connected to your computer's USB port.
2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.
If you cannot turn off the device using the slider, press and hold the Sleep/Wake and Home buttons at the same time. When the device turns off, release the Sleep/Wake and Home buttons.
3. While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on.
4. Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears, release the Home button.

Note: You need to be patient and repeat the above many times to recover your iPad. Data will be lost.

You should really read the manual.
"How do you restore from backup? "
Restore. When given the choice, choose to use backup.
"And how can I check to see if the pics and videos are on my computer somewhere first??"
They would only be where you put them. What program did you use to import them? Pics/vids taken with ipod are not part of the sync process at all. You should be importing them just as you would with any digital camera.
If you did not import them, then they are not on your computer.

You're not alone. I am having similar problems with my Ipod 5th gen 30gb.
When I connect it to my laptop (Vista - basic) it is not recognised by itunes. Itunes simply locks up.
So far I have tried the following to no avail:
Checked my pc's device manager - it recognises the device and says it is functioning properly.
Checked the drivers to make sure they are upt to date.
Uninstalled & reinstalled a previous version of itunes (as it worked fine before the latest release).
Reinstalled the latest itunes.
Reset the ipod.
Put the ipod into disk mode and reconnected to itunes.
Have tried to use the windows tool to scan and fix any bad sectors but it fails to complete a scan without locking that up as well.
Placed into disk mode when fully charged and then allowed the battery to drain completely. Then reconnected ipod (in disk mode)and it still is not recognised and locks up itunes.
At this point I dont really want to part with another $300 odd dollars for a new one.

White screen at startup and stays?? How can I get past this?

Safe Boot is perfoming a disk integrity check and repair process which may take a long time. Let it complete, though if the startup disk requires repair to begin with, it is likely already in a failed state.
If the Mac eventually starts, take that opportunity to back up your important data if you have not already done so. It may be your last.

Won't boot. Gong sound and Black screen alternate over and over and over.

So yesterday, on a Mac Pro (newer, came with slim keyboarboard) I tried to launch iPhoto. The Icon bounced as though it was opening like 4 different times then suddenly the screen dropped to a really low resolution (i could tell by the size of the cursor) and all blue. Nothing would save it, so I forced it to shut down. Now, when trying to boot it cycles between the gong and a black screen. Over, and over. Even when booting from a disk. If I hold down option it will take me to the screen to select a drive/disk/partition to boot from, but as soon as one is selected: black, gong, black, gong, etc.
I think it's important to note that this bad boy is equipped with Faronics Deep Freeze. It's had problems 3 times within the past month or so, where a clean re-image is necessary. Any ideas on the problem would be great!

Hi Riley Florence;
I hope you have a back up because it sounds like your hard drive has given up. I suggest that it time for it to go back to Apple.
After reading some of the reviews on Faronica Deep Freeze and its security vulnerabilities, I am not going to install it on any of my Macs.
