MBA repeats startup chime but doesn't boot up. Why?

MBA timed out while Applejack was running then shut down and now repeats startup chime but fails to boot up.

And exactly what MBP model do you have? What version of OS X is installed? What version of AppleJack did you use?

Powerbook powers on, but doesn't boot

I posted this at the end of another thread with the same title and got no response. Someone please help me!
Okay, this same exact thing has just happened to my Power Book G4. I have some important stuff on there and I haven't had the chance to back up my stuff in the last couple of weeks. For those of you who've has this problem repaired, did it wipe out all the stuff on your hard drive? I called apple and they told me to connect it to another apple computer and using target disk mode I should be able to get my stuff off of it, but this did not work. Why would they even tell me to try this? My computer turns on, but doesn't boot up! Is there anyway to save anything on my hard drive? Apple said I could also go to the nearest apple store, but that's like 150 miles away from me. Am I just screwed?

You might try booting from from the Install & Restore disc that came with your machine by:
1. Inserting the disk, pressing the power button, and immediately after the startup chime, press and hold the C key until you see the spinning gear icon appear on the grey splash screen.
2. After the machine has booted, pick your language, and when the Installer window appears, do not press Continue, but go to the Utilities menu in the menubar and open Disk Utility.
3. In Disk Utility, choose your normal startup volume in the pane on the left and then click Repair Disk. If any errors show in the window, run Repair Disk again until you see 'The volume appears to be OK' in green.
4. Quit Disk Utility, quit the installer and attempt to restart into your regular startup volume.

I have a mid-2010 27" Quad Core i5 iMac running 10.8.3. Startup disk recognizes the primary hard drive as a startup volume but will not boot from it. Have tried zapping PRAM, ran disk utility. No errors reported Any thoughts?

My bad Eric. The startup preference recognizes the primary as a 10.8.3 startup volume but when u select it the system does not boot. I can only boot from my external backup drive

Powerbook G4 15" - Hear startup chime but nothing else happens

I hear the startup "chime" but then nothing.
Screen black. No light in power button or hinge button.
I can shut down by holding the power button.
Disk in CD drive, tries to work. Cannot eject, even when holding trackpad button.
Took out battery and disconnected power for 5 mins.
Tried to zap pram, wouldn't let me.
Worked fine two days ago, new problem.
What can I do?

Sounds like you might have the dreaded "lower memory slot failure", check this knowledge base article for more information: http://docs.info.apple.com/article.html?artnum=303173

Mac Mini won't boot, repeating startup chime

This afternoon I noticed that my Mac Mini (1.5 GHz Intel Core Solo) was acting sluggish. I opened up activity monitor and saw that the process 0 (kernel_task ?) was using about 50% of the CPU. Assuming that it was in the middle of something, I left it alone for another 10 minutes. Still 50% red in the CPU Usage graph in Activity Monitor. I then turned the computer off. When I turn it back on, I get a gray screen, one normal startup chime, followed by somewhat quieter startup chimes about 1 -2 seconds apart. I've tried resetting the PMU, starting up with no USB connections, safe mode, by CD, etc. I don't think the keyboard is even recognized. I know that works, because I tested it on my laptop.
Any suggestions?
Thanks!

OK, well it would not make any difference that the install disk was already inserted - as long as the Option key was being held down at the right moment, the system would go into the boot loader screen even if there were no bootable volumes.
Make sure the Option key is down immediately you hear the first chime. If you've been doing that, it would be an indication of a more serious fault.
Try an SMC reset to make sure the system hasn't just corrupted the management controller, then try again.
An SMC reset can be accomplished as follows:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.
If that doesn't work, there's a hardware fault. In which case the nature and pattern of sounds you hear after the initial chime may be the clue, since these may be the system giving an audible report from the power-on self test. Are these regularly repeating beeps? rather than chimes? If so, you should hear a pattern of 1, 2 3 or 4 of them followed by a second pause, then repeating.

MBP chimes but doesn't start

I updated my MBP and was in the middle of a project in iMovie, left for a bit and comp went to sleep. Turned it back on only to have the rainbow wheel spinning for a long time. Shut down the comp and tried to restart it.... I get the power up chime, apple logo, grey spinning wheel, and progress bar..... Then it's shuts down. Tried a safe boot but doesn't work. Any advice would be appreciated.

This may or may not work.
Try starting your MBP with thw OPTION key down. This should result in a display with 2 HDD icons. Select the recovery icon, on the right. There will be a 4 option menu. Select Disk Utility. Then select Disk Utility>First Aid and run Verify and Repair. Then if successful, restart your MBP.
If you cannot get to the inital display, indicate if your MBP came with installation discs or get the serial number from the bottom and enter it here:

Post back with the information or results.

Weird Startup Chime / Hit-And-Miss Booting / freeze when door is closed!

I have a Digital Audio - originally 466.
Upon startup, instead of hearing "BONG" I hear "B-static-O-static-N-static-G-static"
Most of the time, the computer boots fine. Sometimes it will never send signal to the displays. rarely, i'll hit the power button, and hear the remixed chime, but the power button goes out - the the case fans still running.
Also, if I keep the door to the computer closed, the computer will eventually freeze or panic.
Replaced onboard battery, reset stuff in OF, replaced ram, replaced vidcard, has two hard drives, has cpu upgrade to dual 1ghz.
I'm stumped!

All of the fans work properly, nice and clean inside, too.
Nothing plugged into the audio ports - use a USB audio interface. The goofy startup noise happens irrespective of the use of the audio port.
the CPU is a sanctioned (or whatever) OWC upgrade.

Apple tv goes into sleep mode but doesn't boot up (tv screen is blank) unless I power it off thn back on.

apple tv 2 will operate normaly after initial startup, but doesn't always wake out of sleep mode. Status light is steady white but no image is displayed on the tv screen. Power the unit off then back on and the menu appears on the screen. Any thoughts? Just did the latest software update...

Try restarting the Apple TV by removing ALL the cables for 30 seconds.

IMac G3 - no startup chime but power on

Hi there, I have a very strange problem with an iMac G3 slot loading. It seems to be the same problems as other users have with their iMacs. The trouble began by switching off the iMac - the power-led keeps on (green). Then my daughter in law pulls the power cable. By restarting the iMac only the power led is on, but the mac is absolutely "dead". No startup chime no spinning of the hard-disk...
I do the following: Change the battery, reset the PMU, check the power-cord, unplug and plug the RAM, check the hard-disk. But I can´t find what the problem is. Next step I swapped the logical board with another iMac - but I can´t believe: it is the same problem. The board is o.K and therefore the Power Management Unit too, because it is on the board, or not? Is there someone with any idea? Thank you for your help,
Matthias from Germany
iMac G4 Mac OS X (10.4.5)

Well if its not the logic board then it coul be the mother board but I dought it. It sounds like a RAM problem. When you turn on your iMac does it make a long beep or possibly a few long beeps? Does the powerlight flash orange and green? Try some different RAM.
Hope this helps

Satellite A300 - Turns on but doesn't boot

Hello,
I have a Satellite A300. I have had several probems while booting since 2 months ago: When I want to turn on my laptop, it turns on but the screen keeps black and it doesn't load the "Toshiba Leading Innovation" screen. The "Satellite" light (at the left of the mousepad) is on (it would only switch on a second while booting and then would switch off) and it doesn't turn off.
I have to retry for so many times with all the possibilities: Without battery, only with AC adapter, with both of them but it doesn't boot. I don't know what can I do. I have always to hibernate my laptop bacause I am afraid to can not boot it the day after.
Could you help me? If it cares: I had to buy a new battery (not Toshiba original) because I had to change the original one. No more changes in my laptop.
Thank you very much and sorry for my english writing :S
Diego

Thank you for your reply PinkPanther,
I think it isn't fault of the battery, because my laptop doesn't load the Bios neither the "Toshiba Leading Innovation" screen not even tryng to switch on only with the original Toshiba AC adapter.
About the external monitor: it's true many times I connect my TV by the HDMI port. But i think it isn't the problem. As I said first, there's a light (is writen "Satellite") at the left of the mousepad that lights when the laptop turns on and when comes this "Toshiba Leading Innovation" screen, suddenly it switchs off. So when I have this problem with my laptop, this light keeps on. I think that if it was problem off the monitor, this light should turn off and load the OS, and then I must hear the sound at the begining of the OS...
As you say, maybe it's a serious probelm... I posted here because I hoped that anyone had the same problem, resolved it and could help me

System restored but doesn't boot

The hard drive in my Macbook died. I replaced it with a 320gB drive.
We have a Time Capsule that Time Machine backs up to.
I booted from the Leopard install disk and restored from the time machine backup. The system said it restored successfully but then when it tries to restart and boot I get the gray screen and the spinning icon for a few seconds and then the system shuts off. It does this every time. The install disc is still in the drive so if it simply wasn't finding a startup directory there it should have booted from there.
I tried zapping pram and I used the Leopard install disc to make sure the HD was set to the Startup disc which it was.
Any thoughts?
Thanks,
Shawn

I have also run disk utility on the drive. Repair drive said the drive was OK. I repaired permissions which did some repairs to some printer libraries but that didn't make a difference in the system not booting.

Bootcamp volume selectable in Startup Disk but won't boot. Bootcamp not visible with Option Key

My bootcamp volume is selectable in Startup Disk System Preference, but Windows 7 will not boot stating no bootable volume. The Bootcamp volume does not appear when option key held down during startup. Windows 7 booted fine before I booted into MacOS. When I tried to reboot in Windows 7, that's when I received the non-bootable error. All looks fine on the Windows 7 volume.
I'm working with a Macbook Pro Early 2008, 256 GB SSD, Windows 7 and the Boot Camp Support Software 4.0.4033.
I tried to re-install Windows 7 on its 32 GB partition, however Windows reported volume is not in proper format???
I tried repairing my Windows 7 volume with my install disk, but apparentl after having to update my initial Windows 7 instalation (disk bought in 2009) about 3 or 4 times, my Windows 7 install disk reports it cannot repair the now updated version of Windows 7 on my hard drive. Lovely. Brilliant engineering.
I looked into editing my partition table, but that process appears more a hack/bandaid for the underlying problem that more than likely still exists.
Any suggestions, other than painfully starting from the beginning???
Thanks.

Well, want to rule out drive case,, as those do come up with EVERY new OS, just hit Lion 10.7 forum when it came out, or when 10.6.0 came out 3 yrs ago.
Maybe the power adapter is the weak link.
As I said, and goes back yrs, not a fan of FW/USB/eSATA case from major vendors (LaCie, WD, Seagate etc).
And you could try another case. Be sure to buy a case that lets you swap in your own hard drives though.

My 3Gs doesn't work anymore after upgrading to Iatest Update. Still It's resetting itself but doesn't boot. Can anyone help me?

I updated my 3GS with the latest update. But it doesn't work. Still I only see the Apple Icon on the display and almost every two minutes I get the sound of resetting/rebooting itself by the phone.
So, what can I do?

If iMovie won't start, one thing to try is delete the iMovie Preferences file:
Go to your hard drive Mac HD > Users > (your home folder) > Library > Preferences > com.apple.iMovieApp.plist
Drag that file to the trash, reboot your Macintosh and try to launch iMovie again. Failing that if you can write down the error code and report that back to the Discussion Group someone else might be able to start helping with trouble-shooting the failure.
