Screen Problem/Will not boot?

My black macbook purchased in 2008 running OS X (10.5.8 I believe) would appear to not be starting up. When I turn it on, the screen flashes and I hear the chime and then it goes black. I'm not sure if this is a screen problem or something else. I can hear something running despite the screen being black. When this first occurred I was watching a video on youtube and I could hear the video still playing and the computer still function but the screen went black. I tried to boot it in safe mode and that did not work. I tried taking out the battery and yet again, that did not work. Is there anything I can do? Has anyone else had this problem?

Blue screen, computer will not boot up

My computer, when powered up gets stuck on a blue screen and will not boot up. I have restarted & held down the shift button for safe mode & it goes to a white screen with a grey apple icon but will not move past this screen. How do I get the computer to boot up?

Sounds like your system is hosed. Try [repairing the hard drive with Disk Utility|http://support.apple.com/kb/TS1417]. Of course, from the sounds of it, even if you get the drive repaired, it may not fix the problems with your system.
Do you have backups? If not, your only priority at the moment should be to figure out how to back up your data, or what data may still be intact if your drive is badly damaged. If you have another Mac, the easiest way to do this will be to boot the machine into [FireWire target mode|http://support.apple.com/kb/HT1661] and copy whatever data you can.

Hey i kind of have the same issue.
I bought a iphone about 1 year ago and about 2 months ago i was not able to see any wifi connections in the area or connect to any even though i was sure that there was a wifi nearby and my fellow coleauges could connect to it with their iphone. I thought that this might have something to do with the "restrictions" so i went to turn the restrictions off but realised that it had a passcode that i had forgotten. I wasnt able to restore it within the iphone so i restored it from my computer. Once i had finished the iphone had a " connect to itunes " on the screen and it said that there was no sim car installed, even though there was. I tried cleaning the sim card and everything else, i tried connecting it to itunes but it just said no sim card installed. Now i cannot use my iphone or cant even activate it. I have also tried to restore it in recovery mode but ended up with the same problem. Please Help.! Thanks

Trying to upgrade to 10.4 - Problems will not boot now

Hi,
I tried upgrading to 10.4 the other day. Currently my iMac is running 10.3.9.
When I tried upgrading, it would start the install and than freeze and wouldn't go any further. After several attempts I ran the Tech Tools CD i got with my computer. It said I had a problem with the Volume Structure. So I click the fix button and I assumed it was fixed and it continued to check everything else ok.
When I restarted the computer it would not boot into the operating system. It freezes on the gray screen with the loading bar. Left it alone for about an hour and it was still there. The only way I can boot it up now is with the Tech Tools CD.
Any ideas what happened or what I should do?
Thanks in advance.
Mike A.

Hi Mike:
I feel for you. I just went through a similar ordeal with a G4 (look here for details).
I think at this stage your problem is that you don't have a complete system installed. At least I was able to remove the hard drive and move it to another computer to get Tiger installed on it.
You could try cleaning your Panther CDs and trying again, but I suspect the source of your problem lies elsewhere: the logic board. If ds store is correct, and the firmware did get hosed during the upgrade, then we're both looking at expensive repair bills to get it fixed.
I'd also try removing all but the original (256MB) RAM, zapping the PRAM, and resetting NVRAM. It can't do any harm, and you might get lucky. You can replace the RAM once you get a system installed.

Problem with l355 s7817 Blue Screens and will not boot up

Hello, I am new to this forum so excuse my forum etiquitte. I have a l355 S7817 for 2 yrs and I have had to do a system restore on this laptop twice. I am a Vista SP2 user that has been getting blue screens recently when trying to boot up. I have gone and cleared cache, temp files, temp internet files and removed new software that was loaded and I am still getting the BSOD. I can come up in safe mode, sometimes with networking but when I go to copy data to my external HDD so I can do a system restore again, I get the BSOD. I have tried to restore from a chk point and still get errors. I need to gather my data off the drive so I can do a restore but I cannot get my data due to it fails in the middle of the copy. Any ideas what could be causing this.
I had no problem with my laptop all last week but come Monday, It started doing this. I get a message in Safe mode saying Windows has recovered from an unexpected shutdown. Windows can check for a online solution to the problem. It finds nothing and in the problem details it says
Problem event name Blue screen

My 13" MacBook Pro will not boot up - all I get is blank screen

The MacBook Pro is only 10 months old and is up to date on all OSX updates. I have been using it all day and suddenly this evening it just went to a blank screen and will not boot up. No fan, nothing. Nada.
I have tried the following:
checked magsafe and it is clean of any dirt
checked battery (pressed button on side of Macbook and got 6 green lights coming up)
There are no USB peripherals connected
tried pressing CMD+CNTRL+Start button and nothing happended
tried holding down start button for 30 seconds
The mac has not been dropped or had water on it.
Any other ideas?
Cheers

Which OS do you have...if it is Snow leopard then press shift while starting up, i.e., immediately after pressing power button
if the os is Lion or Mountain Lion press command+r to goto the restore thing and then disk utility to rectify your problem

White 2008 MacBook will not boot completely (hangs up)

For Christmas 2008 I bought a New 2008 Apple MacBook (White) for my 13 year old Grandson. He gave it back to me to "fix" .
He said the following problem ----will not boot/Hangs UP during boot---- *first appeared immediately after he downloaded and installed an "APPLE/MACBOOK" update of some kind last week.*
DOES THIS SOUND FAMILIAR TO ANYONE OUT THERE? IF SO I WOULD APPRECIATE YOUR SUGGESTIONS.
More info:
It will not boot completely. when powered on it-- chimes once with the normal Mac sounds (Not a POST Beep error)---- and a white screen---- with apple logo in center appears--- after several seconds a small spinning "activity/busy" circle appears below the logo. This circle appears and spins for about 3 to 4 minutes with no other activity happening. Then the screen goes blank and power goes off.
Oh yes I am not certain as to the Exact OS designation that is installed (sorry)
I am new to Mac but have checked:
The power (A/C, and supply are on, Mag power cord attached and battery charge light on battery is blinking green with 4 steady green lEDs on--- (So I assume I'm OK with NO power or battery issues)
I then tried to boot into "safe" mode. (shift key when power on) (No change)
Then I tried Cmd, Option, P, R keys as suggested in manual during power on to reset nv(p)Ram (No change)
Grandson is searching for manuals, OS Apple Hardware troubleshooting disk etc. While I wait to receive those items from him --------
Does anyone have any Ideas /suggestions?
Thanks in advance!
Joe

HI Joe and Welcome to Apple Discussions...
Since you can't boot in Safe Mode that's not a good sign. You really need those install disc(s) to repair the drive if necessary.
When you get the install disc...
Insert the installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open look at the bottom of the window. You will see Capacity and Available. Make sure you always have a minimum of 10% free disk space.
You can try something that doesn't require the install disk and that's Reset the SMC
If you can get the MacBook to boot up to the Desktop, click the Apple Menu then click About This Mac. The Mac OS X version number will be displayed there. 10.x.x

Touch will not boot

It is stuck on Apple screen and will not boot up. What should I do? Other than restore.

I've been having the same problem, as have others. You will have to connect it to your computer and restore it. Here are two threads on the subject that should be helpful:

Hp pavilion laptop will not boot up.

I get this error The file header checksum does not match the computed checksum. I'm not able to do anything with it after this screen, it will not boot to safe. What can I do?
I've removed the battery, which is dead anyway; laptop is plugged in. Have tried different power source and that doesn't help.
There is no blinking cursor, etc. I have tried F2 & ran that memory & hard disk diagnosis & nothing seems to be amiss. On the error log I really didn't see any errors.
I don't have recovery disc either but laptop won't boot to cd rom drive so even if I had recovery disc am not sure that would work.
Help please I'm at a loss now of what to do. Thanks.

MacBook pro will not boot. I get the gray screen, an apple icon and spinning wheel. Tried to start in safe mode but get the same screen. The only thing different was that I loaded the zedge sync app yesterday. Now getting this problem.

Macbook pro will not boot. I get the gray screen, an apple icon and spinning wheel. I tried to start in safe mode, but get this same screen. The only thing different is that I added the zedge update app to do a sync for adding ringtones to my apple cell phone. How can I get a good boot. I am fairly new to apple computer.

Reset PRAM: http://support.apple.com/kb/PH4405 and then try a normal boot.
Run the Startup Manager to select Startup disk: http://support.apple.com/kb/HT1310
If those did not work your disk may be sick or dying. The top priority at this point is to make a backup copy of your data.
Check the health of the disk. Boot in Recovery Mode (Boot, Command-R). Run Disk Utility. Click on the upper left disk icon. Does the S.M.A.R.T. status say “Verified”? If not the disk/SSD is unhealthy and needs to be replaced. Even if it does not show “Verified” you can still attempt a backup.
Click on the icon indented below, usually called “Macintosh HD” and Verify Disk. If it finishes with a green “OK” message then all is well with the disk. If it shows errors in red then you have found a problem to address once the system is backed up. Do not attempt software repairs until you have secured the data.
If the disk will not show up at all in Disk Utility as your ran the tests above then it may be dead or it may have a bad internal SATA cable. A trip to an Apple store for confirmation would be in order.
If you have an external disk drive you can use as a backup drive then do so. If not Google “Hitachi USB 3.0 external hard drive 1TB” to purchase one or go to a brick-and-mortar store (including an Apple store) to pickup one. Any 1 TB external drive will do.
Assuming it is still breathing you can try to recover the data without booting from the sick disk.
Reformat the external disk. (This will erase all data on the external disk.)
Boot in Recovery Mode. Start Disk Utility. Plug in the new disk. Select it’s disk Icon (the second one down, left justified). Select the Partition tab.
Partition Layout > Single Partition
Name: Emergency Recovery 1 (or whatever name you wish to use)
Format: Mac OS Extended (journaled)
Options… > GUID Partition Table > OK
Apply
Select the Restore tab.
Drag the old system volume (Macintosh HD) to Source.
Drag the new disk volume (Emergency Recovery 1) to Destination.
Click on Restore.
It may take a long time for the backup.
If that will not complete post back for other emergency data recovery methods, including those from a brody.
If the backup succeeds, use the First Aid tab in Disk Utility to select the old volume (Macintosh HD) and Repair Disk. If it does not finish with a green OK message try to repair it once or twice more. If it repairs with a green OK message, will it boot normally? If not, boot from the Recovery Partition and reinstall OS X.
If it is still not healthy, post back for further instructions.

Macbook Pro will not boot up normally ***Not Normal Problems***

Ok. I have an older 17" Macbook pro 2.33 (10.6 fully updated) that will not boot up in normal mode. When I boot it shows "blocks" of different colors and will not get past the blue screen sometimes. When it does get passed the the blue or grey screen it is a split screen of white back ground with large black blocks seperating the sides. I have tried swapping out harddrives with a known working one with an OSX image on it-no good. I have tried swapping out ram-same thing. I reset the SMC and PRAM-only colors changed in the blocks. I have ran disk utilites disk and permisions with no problems. I can't boot into a restore disk using the c key during boot, It locks up at the same screen. Nothing works except safe mode. I can boot into safe mode and everything works just fine with normal screen and all. Now I tried runing the Lion installer thinking it is and driver issue but I can't get Lion to boot to the hard drive and Snow leopard just reboots back to the same screen. So how can I get Lion to install or Snow Leopard?
What can I do? I noticed this last weekend when I tried to reboot my MB Pro and it started this. Well Apple pushed and update last friday - I needed to restart it again and this happends. I thought it was a logic board at fist until it booted fine in safe mode.

Sorry. What I mean is I selected the SL boot up in the start up panel and it would not boot into the cd. The CD rom sounds like it just keeps reading with it slowly loading from grey screen to blue screen to the Block screen. Almost like it is booting into normal mode from the hard drive.
What I can't understand is why it runs fine is Safe mode?
Also why do I get a " this disk cannot be used to start up your computer" message on my hard drive when trying to install Lion in safe mode? Well why not it's the only hard drive in the computer?
The first screen shot is the Tech tool showing everything passed the hardware test is safe mode.

Intel iMac will not boot past gray screen

Intel iMac will not boot past gray screen
my system:
new (month old) 24" intel imac, 2.8 ghz, 4 gb ram.
running: leopard (upgraded from tiger, which was pre-installed at purchase), installed 10.5.1 update right before this huge problem occurred.
install discs on-hand: two-disc tiget set, single leopard upgrade disc.
what led to this:
i wanted to install windows using bootcamp on a 50 gb partition.
at this point i was running leopard 10.5
i followed all bootcamp instructions, printing out the guide, as well. once i got into the windows setup, i was prompted to choose a partition to install windows. unlike the bootcamp guide, which showed three partitions, one clearly labeled "bootcamp", i saw only one partition. not wanting to risk writing over my mac partition, i quit the setup and rebooted the mac os. after some googling around, i looked for firmware updates (didn't need any), and then software updates. i decided to try updating to 10.5.1.
i then ran through boot camp again, deleting my previous windows partition, creating a new one, and moving forward as before. once again, i was only shown one partition to choose from in the windows setup. i exited the setup again to reboot through the mac os, but this time, i was only given a blank gray screen.
here's what i have tried so far:
booting from a CD, holding down the C or D keys: no response (in fact, i have to restart the computer holding down the mouse button to be able to eject the CD)
booting with option key held down: gray screen
booting with option key held down with external bootable firewire drive attached: the firewire drive appears as a boot icon, and i can click on it within a five second window, but then the screen freezes after that time period, and nothing changes
booting into target mode while attached to another mac: gray screen (no firewire icon, and drive never shows up on other mac)
resetting NVRAM: i'm able to hear the boot chimes, but no difference in performance. gray screen every time
Safe boot: nothing but a gray screen
Verbose mode: gray screen
Single user mode: gray screen
Single user mode with firewire drive attached: occasionally (not every time), i am able to get the white on black terminal to show up. from here, i'm able to run fsck, but it appears to only be checking the firewire drive. i have tried several times to boot from here, and once it took me to a blue screen with movable arrow cursor, but it never went beyond this.
is there anything else left to try before taking it to apple?
any help would be greatly appreciated.
thanks,

I'd call Apple support at this point. You'll need
to put this issue on the record.
Call U.S. iPod and Mac technical support: 1-800-APL-CARE (1-800-275-2273)
The wait may be long for an agent to come on the line
so expect that and have some other stuff to do in the meantime.
If you have the applecare protection plan, I'd ask about "onsite"
service.
I like your work ! Good luck !

My Macbook will not boot the operating system. It just goes to a blue screen after the apple logo and the spinning wheel goes off. I took the battery out and held the on/off button for five seconds and reset the PRAM. I have the old mac os disk.

You won't lose any data unless you erase your hard drive.
Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c"key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it.When it comes up is your Hard Drive in the list on the left?
If it is then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've selected the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.
