Power Mac wont start up

My power mac G5 wont start up. When i turn it on it comes up with a message saying you need to restart you computer and a load of script drops down in the top left hand corner. I cant get past it and tried everything. This happens everytime i turn it on.
HELP!!!!!

Hi-
Welcome to Discussions!
Have you-
1- Removed/disconnected all devices, except for keyboard, mouse and monitor?
2- Checked your panic log? You can check the kernel panic log any time that you must force restart your computer, using either the power button, interrupt button, or the Control-Command-power key combination. The kernel panic text is added to the log the next time you restart the computer, assuming that you have not reset PRAM at the same time (the kernel panic text is stored in PRAM until you restart). The file is named "panic.log", and it is located on your startup disk at: /Library/Logs/.
The panic report is also the "script" that is displayed when the "restart your computer" message appears. A copy of the report would help.
3- Tried a "safe boot"? Hold down the "shift" key when starting.

4- After checking the panic log, try resetting the PRAM:

Battery full - Mac wont start. Heeeelp!

I just purchased my MacBook a month ago and I love it. Now Im having a problem...
I just had this problem today. The battery is full but my Mac wont start. But when I connect it to the power adaptor - it will start. Should I change something on the Energy saver option?
I've tried to remove the battery and placed it back, but the problem is still the same. I need your help please... thanks in advance.

Yup, looks like you've joined the Macbook Shutdown/won't boot club. Mine did the same after the random shutdown problem. I reset the PMU and NVRAM and PRAM and suddenly it wouldn't boot or operate on battery. Let me guess, it works fine on the adapter, but when you pull the plug it immediately shuts down, right? Even though the battery is fully charged? I'm also from DK. Did you buy yours at Humac? Mine is being repaired as we speak, well actually it's waiting for parts (new logic board and battery) but it's taking forever. Turned it in on july 25th and it is still waiting for parts. My advice is to demand a new one, don't hand it in for repair, because I seriously don't think they know what is wrong yet. What week is your Mac(Check the serial-number and post it)?
I've heard that a lot of people got the LB replaced, but soon after the problems started again.

My Mac wont start! what can i do?

My Mac wont start! After i restarted it for a update it just crash when i try to start it what can i do?

What and why aren't people doing something simple that has worked for the last 10 yrs:
Clone your system before you ever apply updates
Always have a working bootable backup (or two)
Keep the prior version on the shelf
Keep the combo updates around also.
It is not hard or rocket science.
There is no mechanism to undo rollback or restore check points. No utility to sandbox updates and revert as they sometimes go wrong. Things that are overdue.
MicroMat made having an "eDrive" partition s sinch to do and was its own recovery/emergency boot partition.
Carbon Copy Cloner has been around since 10.2.2, and later SuperDuper and others, Clone X etc.
A clean install is simple. Keeping your emergency boot drive for maintenance updated but with just Apple OS and essential drivers.
Use Safe Boot beforehand. People used AppleJack before updates or at first freeze or sign of trouble.
If you have more than enough room for TimeMachine, then a couple options:
Set aside 35GB is more than enough for emergency boot maintenance (Lion Recovery is nice but doesn't have everything your toolbox might want or need)...
Set up a partition large enough for your working system, again 40-80GB should be enough, you won't clone everything as you can leave your home account folders for TimeMachine if you want (but do want to copy your home Llibrary ~/Library). perfect job for Carbon Copy Cloner.
Setting up an external boot drive is 101 along with TimeMachine.
Not a good idea to have all your eggs in one basket two or more backup drives is better but...
TimeMachine - 350% your total files and changes needed to have file history archived,
Emergency OS
Clone OS
I prefer a 1.5TB minimum.would do fine for most.

Hi i am having a big trouble. MY mac wont start past the gray screen. I tried starting on safe boot, single user user mode , recovery mode. Everything it gets stuck on the gray screen i even tried reinstalling it , same thing what should i do?

orshikhfromsc,
boot from the Mac OS X Install DVD that originally came in the box with your MacBook Pro (by holding down the C key as it starts up). When the desktop appears, select Disk Utility from the Utilities menu and erase your internal disk. After it’s been erased, reformat it. After it’s been reformatted, exit Disk Utility and reïnstall the version of Mac OS X from that DVD onto your internal disk. After that version of Mac OS X has been reïnstalled, boot from your internal disk and run Software Update to get it up-to-date within that version; that should allow you to redownload and reïnstall Mavericks, if desired. If Mavericks is reïnstalled, run Software Update again to get it up to date.
If you no longer have the two grey installation DVDs, you can purchase a replacement set from either Apple or iFixit.

Power Failure....Mac wont start... is it PRAM battery??

please help!!
I have a Power Mac G4 which worked perfectly until last night.
We lost power in my whole town.
now the computer won't start. no chime, no power button light... no disks spining or HD noises...
I immediately reset the PMU.
nothing happened.
I read somewhere that you could switch the breaker on the power supply... but I don't know how.
I'm hoping its either a that or I need a new PRAM battery??
on a related note, I have another mac I just upgraded everything on. Logic board, processor, power supply... it won't start up either. though it does make the chime sound and the HD does make noise when I attempt to turn it on. I mention this because I wonder if its the same problem on both machines??
please help!! I'm running out of macs to work on!!! *smacks head*
thank you so much!!

I read the tutorial and following the advice, was able to detirmine it was a bad power supply! I replaced that and now the first mac works great!! thanks:D
but could I ask you about the other mac?? It was a very old single processor G4. with the amber and green lights in the power and sleep button... It worked fine but super slow and needed help. So I upgraded the logic board and processor and power supply so it is now a dual 500 MHz processor.
It turns on, makes the greeting chime sound and I can hear the parts working inside... the problem is the power light does not turn on and there is no display... I even changed the video card to assure it was a working one... but nothing.
I reset the CUDA and have replaced the battery.... maybe I'm just not thinking straight and have forgot something??
thanks for your help!!

Do you know what ii can do? When I press the power butten the apple logo comes up as normal but then nothing happens

To eject the CD, depress the mouse button at startup.
To boot from a CD, you depress/hold the "c" key at startup.
Look at these links.

Power Mac G4 starts, gets to gray screen and shuts down

My Power Mac G4 will start up, but after it gets to the gray screen with the Apple and the spinning gear for a minute or so the computer shuts down. I have started the computer while holding down the "C" with the 10.4 OS disc in and used the Disk Utility to run First Aid. First Aid fails stating:
__*Keys out of order*__
__*Rebuilding Catalog B-tree.*__
__*The volume Macintosh HD could not be repaired.*__
__*Error: The underlying task reported failure to exit*__
__*1 HFS volume checked*__
__*1 volume could not be repaired because of an error*__
__*Repair attempted on 1 volume*__
__*1 volume could not be repaired*__
I have attempted to start computer in safe mode but it just shuts down... no difference.

You have directory corruption on your hard drive that Dusk Utility can't repair. DiskWarrior can probably fix your problem. DiskWarrior by Alsoft

My Power Mac G3 Starts but has a box with a (?) in it

Hello I am new here and wanted to know what you guys think of this because i am not necessarily a mac pro.
When i start my Power Mac G3 All that comes up on my screen is a box with a question mark in it. What i think that means is that i need a new operating system for it but i don't really know that to think because i don't want to mess it up.
Thanks for clearing all of this up

Hi TyboyVisser, and a warm welcome to the forums!
Close, it means it can't find a Driive to boot from..
Couple of things to try...
Hold the Option/alt key down at bootup, does anything show up eventually as a boot choice?
"Try Disk Utility
1. Insert your Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot , (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.
(If perchance you cant Find your Install Disk, at least do the Safe Boot part above).

Power Mac Wont StartUp

My Power Mac just decided not to start up this morning, I have checked the power cords, its working fine, the power outlet its working fine, Is there a way i can check to see if there is Power getting to the board

If by "not to start up" you mean no response at all to the power button, then you need to first check power supply response. With the power cord plugged into the wall, disconnect it from the computer. Reconnect it to the computer. You should hear a small click coming from the power supply on each event. This would be the standby circuits energizing in the power supply.
If you hear the click, then next clue is whether you get the white LED to light when pressing the power button.
It would also help if you provide more specific model information, as there are five major "waves" of Power Mac G5 machines. Find the serial number on the build label and use this site to get that information: http://www.chipmunk.nl/klantenservice/applemodel.html
The build label is found by removing the side panel and looking just below where the processor(s) sit.

Power Mac wont boot

ok I just bought my very 1st first mac last month its a power Mac G4 When I put it into sleep mode i had a black out about an hour later when i tried to start it up I got a gray screen with the apple symbol and the and the scroll symbol hanging I was able to get to the Dos command single user screen and it says this
well this is part of it
(ipc/send) invalid destination port : initCGDISPLAYSTATE cannot map display interlocks
KCG ERROR Failure : CGS NEW CONNECTION CANNOT CONNECT TO SERVER INIT_PROCESSES Could not establish connection to window server./etc/rc.boot: line 1 11ABORT open
KEY:
What does that mean ??? and how can I get it to boot normally and
I have no Boot disk or nothing like that ...

Hi Chris-1, and welcome to the forums!
Oh boy, you're up a creek without the Install Disks, in fact legally speaking, the License to use OSX goes with the Install disc, they should've included it!
Tough without a Tiger Disk, but try fsck...
To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup. Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
2. At the command-line prompt, type /sbin/fsck -fy
(space between fsck and -fy important)
3. Press Return. 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 issue is found: ** The volume (nameofvolume) 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 2 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).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.

Power Mac no start, no recognized HD

Hi, Sorry for my english.
My Power Mac G4 is not starting. There are two HD, If i restart by the first HD, it is not been recognized. If i restart for the second HD its stay processing and nothing happens.
How can i solve this problem?
Thanks

Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk. Do they show up there? Please check the S.M.A.R.T status also.
You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them.
Cheers!

My Macbook power button wont start up

Hi,
My Macbook wont start up at all. I have charge in the battery and the power lead lights up green when plugged in, but when I press the power button there's nothing. This happened after the macbook turned off whilst I was working on it. I tried restarting and it got to the logo page then turned off again. I've had no power since.
I've tried resetting the smc with no luck. Any advice would be grateful before I head to my local apple store.
Kind Regards

Quick update..
I have opened it up, and the only visible problem seems to be the orange ribbon cable which is on top of the hard drive. There is a white chalky residue/possibly dried-in glue?
Does anyone know if this might be connected?
Thanks for your help!

TS1884 if i reinstrall mac os (snow lepord) will i loose my files,i have no backup and i mac wont start , safe mode never gets past spinning loading icon and i left it all night

when i used disk utility when booting from the install disk im told the "disk is damaged " but the repair utility wont run sand tells me to back up etc....
i cant make a new partition , and i cant make an image
please help

I fully agree with BDAqua.
Don't do anything with this Mac until you have an external disk which you can boot your Mac from.
Not all USB disks are easy to boot from - FireWire is better
When you have a suitable empty external disk I advise:
Put install DVD into damaged Mac
partitioning external disk into 2 volumes
install OS onto one volume of external disk
Don't import anything during install process - it may reintroduce historic problems
Boot external disk
Use finder to copy critical data from Mac to volume of external disk with OS
Use Carbon Copy Cloner to clone the whole Mac hard disk to the other external volume
Boot into installer DVD and erase Mac's internal disk
Partition internal disk into 2 volumes and install OSs as required

Mac wont start if ADC is not Connected??

I have a G4 Quicksilver Dual processor, with Tiger OSX installed on it. The video card installed has a ADC and VGA connector. I recently wanted to change from the ADC monitor to the VGA(new PC Monitor). But when the apple display is not plugged in the computer wont start.
Why
I have done all the system preference stuff and changing secondary to primary and even swapped video cards with another machine which i know works with the VGA connection.
Please Help
Cheers

I do not believe it's the Graphic Card, I think it would need either a new Logic Board or Power supply.
Which card is it exactly, some can run both monitors at once.
And there may be a slight possibility that a Keyboard like this with a "Power Key" at the top right corner may work to start it...
