Quad wakes, screen doesn't!

A few moments ago, I woke my Quad from sleep. The machine fired up fine (no roaring fans or anything), but the screen stayed black. Tried unplugging, plugging the power for the display, unplugging, plugging display USB connector etc. Nothing. It's a 30" Cinema Display by the way.
I have no PCI cards, and my RAM is kosher apple. No third party USB/FireWire devices connected either. Is this a known problem by any chance? I couldn't find any references to it on this site.
I have a bunch of unsaved work so thought I'd check here first to see if anyone has a snappy answer about how to get my screen back without a hard restart.
Thanks!

A few suggestions:
Can you put the machine to sleep again, using either the keyboard or the front panel button? A new wake event may bring it back to life. control-eject will bring up the sleep/restart/cancel/shutdown dialog, even though you cannot see it. Hitting "s" while the dialog is up will cause the machine to sleep.
Did you try plugging the monitor into both connectors on your graphics card?

Screen doesn't come back after sleeping

Occassionally I find that after closing my MPB to put it to sleep the screen doesn't come back up after re-opening the laptop. The pulsing white light which tells you the machine is sleeping goes off, so it seems as if the machine has woken up.... but there's nothing on the screen. I'm forced to use the power button to shut the machine down and start up again.
Something to worry about?
(p.s. I just tested it again and noticed that when I close the lid the white light isn't pulsing, but rather stays lit)

I just recently (within the last two days) started having this problem myself. I've only owned the Macbook for a few months (purchased it from Apple online store right before the new ones came out). I am thinking it might be due to a recent update or something.
When I close the lid, laptop sleeps but when you open it you can hear the CD tray spin up like it's trying to wake but doesn't. I've tried adjusting screen brightness via f-keys, changing the volume, etc. but seems like system is just locked up. I've been having to hold down the power button and force a reboot.

My sleep/wake button doesn't work on my iPhone 4 is there any apps I can download to make it sleep

There isn't anything you can do about that except to get the sleep/wake button fixed. It is an integral part of the phone and is used for troubleshooting steps as well. Using a device without one is just waiting for trouble. However, if you want to, you can go to Settings>General>Accessibility and turn on Assistive Touch. Then to lock the phone, tap on the Assistive touch button, tap on Device, then tap on Lock screen.

My palm m105's touch screen doesn't work properly after a sync.

I dug out my old m105, put new batteries in and start it. On first launch it auto runs the alignment tool, and after touching all the points it goes to the main screen and works fine. No problem till here.
Now, I plug it into my old computer which still has the palm software with my apps, and I run the sync operation (from the palm device sync manager, cause I lost my cradle and I'm connected via the serial cable), and it syncs fine BUT, here comes the problem, when it finishes the sync (successfully) the touch screen is all misaligned. I can't go back to the home screen or do anything useful.

Maldoman578,
Let's help solve this mystery together! Is your screen freezing after every reboot? Is there any physical/liquid damage on the device? When did this issue begin? Did you notice this after a recent update or application download?

The bottom of my screen doesn't work how do I fix it?

My screen has been cracked for a while now missing a piece of screen in the top and bottom corners of the device. It has been working fine no problems until last night. I think i layed on top of my ipod touch 4g and now the screen doesn't work right and I can't unlock it. I've tried reseting the device and restoring it and that does not help. Is there a mechanical fix I can do I have a screwdriver for ipod screws I just don't know how to fix it. So basically is there a way for me to fix the screen on my device myself if not where can I send it to, to get it fixed and how much and how long will it take. Thanks for any help!

No way to fix it. Seems like a bad digitizer.
Apple will exchange your iPod for a refurbished one for $199 for 64 GB 4G and $99 for the other 4Gs. They do not fix yours.
Apple - iPod Repair price
You can send it to Apple
Apple - Support - iPod - Service FAQ
You can do the exchange at an Apple store

HT1567 my iPAD 2 seems to be frozen...can only be turned on & off. no apps open, screen doesn't move. is restore my only option?

have never done a complete restore and would rather not if there is another way to solve this issue. Only description I can say is FROZEN and one unhappy iPad user! The screen doesn't rotate although the rotate button is set to allow rotation. I've had my iPad for a year and this is my first issue. I'm not really savvy w/ tech. Any suggestions?

Hi DashfromPa
Have you tryd holding down the power button for 10 seconds? That should shut down your iPad. Then just hold down the power button to start it again.
If that does not help then maybe you will have to try pluging it into your pc/mac running itunes then doing a backup and restore. Then hopefull it will work ok.
Sorry but i cant think of any other way if its frozen.
Hope that helps

I cant open apps on my iPhone 4 the touch screen doesn't work. I have restored my phone and still nothing works.

I can't open apps on my iPhone. The touch screen doesn't work. I have restored it already but it still won't work. What can I do.

If the touch screen is not having any response then you probably have a hardware failure. Take your phone to an Apple Store or authorised service provider to have it checked.

The image came up on my screen saying that I need to connect my iPod to iTunes, but I have a passcode, so it won't allow me to. And I want to try and turn it off, but my touch screen doesn't seem to be working either. HELP!

The image came up on my screen saying that I need to connect my iPod to iTunes, but I have a passcode, so it won't allow me to. And I want to try and turn it off, but my touch screen doesn't seem to be working either, so I can't even turn it off since you need to "slide to power off." HELP! I'm leaving on Thursday morning for six and a half weeks, and I absolutely need my iPod with me. I was just at the Apple store today for problems I was having with ANOTHER product, and I don't really want to drive all the way out to where my nearest store is (which is not very near) if I can figure this out at home. My iPod was working totally fine earlier today and last night, so I don't know what happened! Please, please, PLEASE HELP!

Now it's allowing me to reboot (hold down power button and home button and restart), but every time it just comes up to the same thing: the connect to iTunes page. Which is not possible. And I refuse to restore my iPod. PLEASE HELP.

The left part of the screen doesn't work very well

The left part of the screen doesn't work very well. It's hard to erase a letter, and impossible to me to insert the "P".
Does it means that I need to replace the screen? Or there is a other solution?

Basic troubleshooting steps clearly outlined in the User Guide are restart, reset, restore from backup, restore as new.
If you've gone through ALL the troubleshooting steps and you're still having the problem, then you most likely have a hardware issue and will need to bring your phone to Apple for evaluation.

Touch screen doesn't recognize my touch?

My iphone started acting funny the other day. It would only recognize my touch occasionally and was very quick and jerky. Now I cannot unlock my phone at all, nor can I turn it off. The touch screen does not recognize my touch at all. The phone will ring and I can receive texts, but I cannot answer or access my telephone at all. I am very frustrated because I have only had the phone for a couple weeks longer than the warranty and the Apple Store wants to charge me $199.00 to have it fixed. It seems a little bit too convenient that right at the end of the warranty the phone stops working. Does anyone know how I can go about fixing this without having to buy a brand new phone? Any help would be appreciated. I love my iPhone, but I am a little disenchanted with it presently. Please help me. Thank you.

I'm having a similar problem, started yesterday with my 2G iphone
The touch screen doesn't work in a very specific line horizontally across the screen that only comes into play in certain screens:
-Calculator, the C, +/-, div, X buttons no longer respond.
-In contacts, any contact or phone number that happens to fall in that exact place does not respond (very difficult for calling people)
-In the app store I can't log in or cancel out because the 'ok' and 'cancel' buttons are in the dead zone.
-When scrolling once my finger hits that spot it stops.
-In notes I can't click on the third note down. (I'll never know what I wanted to remember on Fed 5th)
...on & on & on...
It is only an issue when the click-able icon is in this 'exact' spot, a little up & a little down & I'm fine.
on another note: Interesting how some one received a free replacement when music couldn't be purchased from itunes (above post), and someone else was told to buy a new phone when they couldn't power down... not fair.

Ipod touch screen doesn't work

The Ipod is not broken, cracked and still seems to operate. However, I can't seem to access my Ipod touch because the screen doesn't react to my touch ... any fixes for this ?

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Two problems with my iPhone: screen doesn't light up at notifications & iPhone says updated apps still need to be updated

Alright, I'm having two annoying problems with my iPhone. It's an iPhone 4.
I'm using the latest iOS.
The first problem is that when I get a notification (a mail, text message, whatever), I hear the sound that it makes, but the screen doesn't light up. Then, when I click the home or the turn-on / off button (basically when I'm in the lock menu), it doesn't show the notification either. Yet, in the notification settings, I've set up to show them. For example mails. I just received a few mails. For mail, I've selected the banner in the notification center. But I see no banner. I see nothing in fact. I can unlock my phone and go in mail, and see the mail there.
What could be the reason for this? I've recently done some changes on it, I mean, not exactly on the iPhone, but in iTunes. I removed all photos from my iPhone (over 3000) and all songs that were on it. I decided to sync only the latest 3 months of photos and 3 months of music. I don't think it's related but it's the last thing I've done with it, and since then this has been happening, so I thought I'd mention it.
My second problem is that, while I was updating my music and photo library on my iPhone, I also synced all app updates. I have around 6 or 7 of them, lurking there for a while, and I never got the time to download them in iTunes and sync them with my iPhone. So that's what I did as well. Strangely enough, when I visit the App Store app, under Updates, it still tells me I have 5 apps to update. I remember one I updated on the iPhone itself.
They're all listed there with the little bar that shows up when it's loading, except it isn't loading. It's just stuck there, at the very beginning. No, not even at the beginning, because the blue little bar that moves forward isn't even present.The also show up this way on my iPhone "desktop" (Home), and it says "Waiting..." below them.
I've tried syncing again, and also restarting the iPhone, but it didn't help. Anyone know what's wrong here?
I appreciate all help. Cheers guys

Nobody? The second problem is solved! But my phone still doesn't light up or shows a banner or anything when for example a mail arrives?

My screen doesn't work

Hello everybody,
I have a problem with my screen, it does not work anymore!
I can't unlock my phone or turn it off.
I try to restart by pressing the power + home but nothing's changed.
I try to restore it but no changes.
I also noticed that the time of the home screen doesn't change.
I managed to unlock the 2 or 3 times but it re-lock in 10 seconds.
PS: my Iphone 4 use 4.3.3 OS.
Sorry for my english, I'm French.
Thank you for your help!

Unfortunately, no changes.
I think I only have to call Apple!!
Thank you for your help Paul.
See you soon.

I dropped my iphone and the screen has blue lines on it. Siri still works but the screen doesn't but the screen isn't cracked or shattered. What should I do?

Bring your phone and $199 to the Apple store for an out of warranty exchange of your phone. You clearly broke it when you dropped it.
