Power switch problems (computer will not start)?

When I woke up this morning my (new) computer refused to start, it worked fine yesterday. Since the LED on the PSU was on I figured that it was something wrong with the power button. I switched places of the reset and power button on the mobo and the computer booted fine one (1) time, but wouldn't start the second time i tried.
Any idea of what could be wrong?

Mac OSX sofware update problems-computer will not start-up any more

Hello
I am having problems & I cannot get back into my computer. It won't complete the start up & just has the grey apple in the middle of the white screen and nothing else.
I have an iBook G4 with Tiger on it - I am not sure which version of Mac OS X I was on when I did the software update but the one I was on last year when I came to this forum was 10.4.8 & I think I have updated it a few times since then so it was probably as I was attempting to install 10.4.11 as I do not have Leopard yet.
The problem began when I did the Mac OSX update that it told me about in software update & when it had completed the update it said I needed to restart my computer which I did & ever since then it will not completely re-boot. (Like I said it just has the white screen/grey apple before it gives the option of who you want to login as).
It seems as though other people have been having similar problems after installing Mac OSX software updates but I cannot find anything here in the forum that solves my problems (or at least not that I can understand at th moment...!)
I need to access things off my computer & can't. Not everything on there was backed up as I had been working on things that day/week. I also don't know how to access my files from another computer (the ones I am trying to connect from does not have tiger it is a PowerBook G4 & it has Mac OSX 10.3.9 on it).
Does anyone know the reason for this problem & how to access files from another computer via an etheret cable in OSX. I know someone who says it was a lot easier to connect computers before Mac OSX days but now it seems really difficult. The only way to start up my iBook G4 is using the Mac OSX install disk & I have tried to verify & repair hard disk permissions using disk utility that comes on the disk as well as verifying & repairing the actual disk but this has not fixed the problem.
I am hoping that I will be able to at least access my files & copy them over to be backed up before I do an erase & install of Mac OSX from the disks. But I am unsure of how to connect my iBook the PowerBook G4 I am on right now. Please help if you know how!
Thanks,
Jazamin

This just worked for my by connecting my other PPC computer to my G5.
http://discussions.apple.com/thread.jspa?threadID=1247044&tstart=0
Go down to the other link and follow the same instructions.
You must start up the good computer and shut down the frozen one. Connect via firewire and then hold down the T key while you start the frozen one.
It will show up on your good one, and then install the combo on the frozen one.
Hold down the power key on that computer to shut it down, disconnect and then start up again.
Good luck

My computer will not start. Just the wheel spinning

My computer will not start. I get the apple with a spinning wheel.
What is happening?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. If you can't get to an Apple Store, go to another authorized service provider.

Mac OS 10.5 / I deleted the " Private" folder ... and emptied the trash. So the folder and its contents no longer exists on my computer at all !!! I do have the OS dvd that i purchased years ago... But my computer will not start from it on its own. My

Mac OS 10.5 /
I deleted the " Private" folder ... and emptied the trash. So the folder and its contents no longer exists on my computer at all !!!
I do have the OS 10.5 dvd that i purchased years ago...
But my computer will not start from it on its own.
My question is what is the open source or terminal language code used to tell my mac to look in the DVD rom drive for startup info? I know that im not the only person in this world who has deleted the "PRIVATE" folder and emptied the trash so it no longer exists on their machine...
That said theres gotta be a common fix for a Power PC G4 that has the OS X dvd in the rom drive but wont look to it to reinstall the vital contents of the PRIVATE folder.
Once again there is not a copy of this file or its contents in the recycle bin...
Also rebooting the machine , pressing and holding the letter C does not prompt the machine to look to the dvd rom drive.
I was reinstalling pro tools and figured I would make some room by cleaning my computers HD...
Lol It was a bad choice to delete this file ...
Thanks guys

Okay sorry it took forever to respond... But for a while there I gave up on this computer!!!!
Money's been tight lately , so taking it in to a professional was not yet an option... though I did consider it eventhough.
Anyway long story short im glad I didnt spend any money because I already had all the tools necessary to fix this issue but was going about it in the wrong way. Okay so here is my scenario and the breakdown... Though this may not fix the issue for everyone :( which *****... But I know we all will have different circumstances.
Anyway here we go...
Okay so first things first.... Years ago I purchased the OS 10.5.1 disk ... So that has always been in my possession!!!!
I realize that some may not have a disk to reflash your OS to your hard drive... but if you do your in luck.
2ndly ... I had an external harddrive with all of my itunes downloaded music so it was more than okay with me to delete my primary HD because all the important stuff could either be copied over or repathed to be located.
-------If you dont want to read through the whole story the fix is summed up in the bottom section-------
Okay so now the SOLUTION!!!!
By trial and error , and pure boredom I opened up my computer to clean the inside...
AND
"Disconnected the primary HD"
and just because ....... REBOOTED my computer. Just to see what it would do.
Upon restart and though it looked like it would repeat its usual cycle...
About 1 minute in to that process my computer froze for about 2 seconds and flashed to the OS installation screen.
Mind you I havent seen this screen yet... Probably hasnt been since I installed the OS years ago.
After a bit of trial and error...
I decided to tell my computer to startup from the OS 10.5 disk located in my dvd rom drive and restarted once again...
this setting is under
Utilities / startup disk
After a little more trial and error ... I realized that I could reconnect the primary HD , restart the machine and return to the OS installation menu.
So upon this discovery
I went to the Disk Utility located under Utilities
Highlighted my primary HD located in the left hand column
Once highlighted ...
In the heading section on the right I selected the option
Erase
in which I erased My current OS on my primary HD ...
I used the first option in the list under security... Because it seemed like the least invasive and would take the least amount of time to see if this process would actually work.
I FORGOT to add something...
Another reason why I deleted my primary HD!!!!!
I forgot to say that it WOULD NOT!!!!! Show up in the STARTUP list as an option...Even After multiple reboots....
But like clockwork... Once I deleted its name IT SHOWED UP as an option!!!!
So back to the next step...
I returned to the STARTUP option under utilities ... And was then able to see MY primary HD now as a startup option...
But ofcourse it had no name because it we previously erased it.
So when Clicking my newly erased HD ... I was almost immediately prompted to REINSTALL the OS ...
Which said it would take about 57 minutes ... But I believe was alot less...
My issue was resolved ... My computer then stated the install was SUCCESSFUL!!!!!!! :))))))))))) lol ;)
It was like I was setting up for the first time ;) asking for my registration info...
The dilemma of deleting the private folder and emptying the trash is finally over resolved. Done ... and no extra money spent!!!!!!!!!
Its really crazy that the information for such a simple thing is not readily available. Especially being such a simple fix.
I know im not the only person who's had this issue , because i've seen numerous posts with similar wording.
I also know I wont be the last person to have this issue... So I hope this synopsis makes sense.
-------One more time the fix------
*Insert your OS dvd into your dvd rom drive.
*Unplug your primary HD or corrupted startup disk
*Reboot your machine...
Upon restart your primary HD will not be recognized...
* you will then be prompted to select your language.
Once selected
*Click Utilities/startup... Highlight the the selection that refers to the OS dvd located in the dvd rom drive.
* Click restart...
!!!!!!!!!!Be sure to reconnect your Primary HD Before your computer restarts and you hear the chime!!!!!!!!
If you do not replug your HD before the chime it will not be recognized.
In that case restart again.
Upon restart once again
*Choose your language...
*Click Utilities / disk utility
In the left column select and
*Highlight your HD ...
Then towards the top portion / center of the page
*Click the heading Erase
Then on the page toward the bottom
*Click security options
This will then provide erase options.
I USED THE FIRST OPTION
"Dont erase data"...
*click OK
* click erase...
Once erased which should take a few seconds
*Cancel the disk utility...
* Click Utilities / startup
And your newly erased HD should now appear in the list.
* Select your drive from the list by highlighting
It should no longer have a name.
*Once selected, you will then be prompted to restart and install the OS to your newly erased HD...
Thats it!!!!
Once everything reinstalls re-add your personal info or registration info and you are up and running.
Goodluck ;)

Hi,
Do you know which test your notebook failed? If you don't know, try the following.
Shutdown the notebook. Tap away at f10 as you start the notebook to enter the bios menu. Under the Advanced or Diagnostic tab you should find the facility to run tests on both the Hard Drive and Memory. Post back with the details of any error messages.
Regards,

HELP! my computer will not start!

Help Please...my powerbook g4 12" will not start up. when i power up, a white screen with a gray apple in the center is all that i see. i was reading some posts on this website, and found some information to bypass, and help move into safe mode, but when i get to the point where i am holding the shift key and the small gear looking thing is turning, it gets to a certain point and the computer shuts itself off. the computer was purchased in 2003, and has worked fine. the only thing i can think of that might have triggered a problem is that i just had to purchase a brand new power supply from apple, other than that there have been no changes in use. any and all assistance is greatly appreciated.
thanks

i cleaned off my hard drive and started over...
I am not sure what you mean by "cleaned off", but if you mean an erase and install, you lose everything on the HDD. I recommend a reinstall only after we have exhausted other possibilities because it is the ultimate invasive procedure. It is also important to have a backup before attempting any major procedure.
i dont have the upgrades i made previously
If you mean the OS upgrades, try this:
Go to Applications > Utilities > Disk Utility.
Select your HDD (manufacturer ID) in left side bar.
Select First Aid in main panel.
Click Repair Disk Permissions.
Download and install Mac OS X 10.4.11 Combo update (PPC)
Computer will restart after installation.
Repair Disk Permissions as previously.
Go to Apple Menu > Software Update
Install all updates.
Repair Disk Permissions as previously.
is there any way to prevent this in the future?
1. Make sure you always have a current backup. The best way to do this is to clone your entire HDD to an external firewire HDD using a utility like SuperDuper or Carbon Copy Cloner
2. Develop a regular maintenance schedule. Here are a couple of articles that will help:

HT1455 What if my computer will not start up in safe mode? What next?

What is the remedy for a MacBook that will not start up in safe mode? The gray apple icon and progress wheel appear, I let go the shift key and the whole thing shuts off again. Please help. Thank you.

My understanding is that the Apple logo is produced by the disk and the spinning wheel shows that the software boot process has started.
1 - Shut down your Mac
2 - Press the power button to start and
3 - Immediately press and hold the Command (Apple) key and the S key
4 - At the prompt type the following and then hit return:
/sbin/fsck -fy
fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issues were found:
** The volume (name_of_volume) appears to be OK
If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
***** FILE SYSTEM WAS MODIFIED *****
Important: If this message appears, repeat the fsck command you typed in step 4 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do). When fsck reports that your volume is OK, type the following at the prompt and hit return:
reboot
Your computer should start up normally and allow you to log in.
Good luck.

my laptop will not start up - all I get when I push power on button is the power LED flashing the following sequence. S-S-S-S-L-L-L-S(S=SHORT, L= LONG)
DOES ANYONE KNOW WHAT THIS CODE INDICATES.
The only thing I might have done was to put a screw (b8 which is 12mm) into the network card locking switch slot on bottom of laptop that says MAX 4mm .
Any info would be appreciated to [email protected]

Hello
Unfortunately here is no public document about explanation of those hexadecimal codes and I can not tell you what it means exactly. The fact is that power supply electronic has detects some malfunction and sends code.
Sorry but I dont believe that you can do something alone. Try please to contact service partner in your country and explain them the situation.

TS1367 my computer will not start up

my daughters mac book will not start up from power button

Hello trayce64,
Thank you for the question. I would be concerned too if my MacBook was not starting up. If you have not yet tried the following steps, I recommend steps 1-6 below to isolate and troubleshoot this issue:
Resolution
If your computer won't turn on, try each of these steps:
Verify you have a good connection from your Mac to the wall outlet by confirming the power cord and adapter if present are securely connected and plugged in. To check if the wall outlet is working, plug in a lamp or other electrical device.
If the wall outlet is working and you continue to have no power try another power cord or adapter if available. If it works you may need a replacement cord or adapter.
Note: See Apple Portables: Troubleshooting MagSafe adapters for further troubleshooting with MagSafe adapters.
Disconnect all accessories that are plugged in to the computer, such as a printer, hub, or other mobile device.
If your Mac supports user-installable memory, solid state drive, or hard drive, and you recently installed any of these, make sure they are installed correctly and are compatible with your computer. If possible, reinstall the original memory or drive into the computer to find out if the behavior persists afterwards.

Blackberry 6.0 problems- computer will not restart

I tried to install the blackberry desktop software version 6 on my computer. The computer will not work now, CPU usage is at 100 % and System Restore did not help fix the issues either. Computer is running Win XP SP3, The installation has also affected the Wirelees card on the computer, and will not let the computer run unless the Wireless card id disable and shut off. There is also a file that keeps trying to install call Roxie Media Manager, which the file is not where to be found and is not downloadable on you support site. I am in the process of reloading my entire computer to fix this problem. THIS is the second time that I have had to reload because of doing an update from Blackberry. If there is a solution for this it is not listed in any forums on this site. If your software has not been tested with all operating systems, this needs to be stated in the download information before someone downloads the new updates. I love my phone, but the Desktop software is a major drawback to anyone that needs their computer on a daily basis. Please come up with a fix or notice that will avoid this problem.

I've never had any problems with DM6 on WinXP, SP3.
I've mentioned on here several times that I don't recommend using the Roxio software, it's just to buggy I think.
