    Yes the computer started right up & is running with no issues-- as an added test there appears to be voltage display mini leds, (green) on the bottom center of the motherboard. (visible thru the bottom vent screen by the memory chip cover). looks like 3 light up when power is correct, I only had one light before changing the power supply.

  • Bill Mar 15, 2009

    Here's a few suggestions: There appears to be a couple different power supplys in the imac 24's - my suspect model had 2 large aluminum heat sinks on the bottom & sticking out the side. The burned part was visible immidiatly on top of the board (surface mount transistor), examine the power supply components for damage, including any capacitors. A swelled silver top indicates a failed cap from overheat and will need replaced. Likewise I have repaired many motherboards with the swelled capacitor problem. Using a voltmeter, check for presence of +5, +12, +3.3 volts coming out of the power supply to the motherboard and/ or to the hard drive when the computer is turned on. I think there is an addtional +24v to the display.

    http://en.wikipedia.org/wiki/Serial_ATA for power pinouts to the sata drive. Also a bad component may rob power- a non-running fan could be shorted, try unplugging anything that doesn't start--hard drive power- dvd power- fans- or display- (to test without the display listen to see if the hard drive spins up)

Ways to burn Discs with Finder and Disk Utility in Mac (versions OS X 10.4 -...


Without purchasing new disc burning software, there are actually 3 ways to burn CDs & DVDs in your Mac OS X system (Mac OS X 10.3-10.6)

There are methods using Finder and Disk Utility.

Both are easy to do and when set up to use will have you burning music, video, data, and image files (ISO) to CDs or DVDs in no time at all.

-------------------------------------------------------------------------------------------------
BURNING DISKS WITH FINDER

1.) Create a Burn folder and burn a CD/DVD

* The easiest way to burn a disc with Finder is to create a Burn folder with Finder. Here's how you do that:

* Click on any blank space on your desktop and in an instant, Finder will appear on the Apple menu bar next to the Apple menu icon.
• Click on File and select from the drop down menu

9696d88.png

* This distinctive folder will now appear on your Desktop

597c898.png


* Now insert a blank CD or DVD and in moments, you will see this window pop up:

b3dbf79.png

• Just click the OK button.


* In a few more moments
on your desktop, you will see this Untitled DVD (or "CD: for CD-ROM Disks) icon:

10ec18d.png


• Now you can either drag and drop files into the folder, or just double-click the folder and also drag and drop files into the open Burn Folder window

* If you notice, each file you drag (or copy and paste) into the Burn Folder window will have a small curved arrow at the bottom left corner of the file.
That is merely a designation that the file is a image of the actual file and ready to be burned to the CD or DVD you use.

e3c6169.png

* Notice the Burn button (highlighted in the red box). This is the button you will press, to commence the burn (or copying) of the data you have placed in the burn folder to be copied to disk.

• Click the Burn button, name your disk and that is all it takes. When the process is complete, you will now see a formerly Untitled Disk icon on your desktop replaced with a "Your_new_disc_name" DVD.

(Additional Note: If you wish, you can also simply bypass creating a Burn folder, insert a blank CD or DVD and simply drag and drop or copy and paste files into the open window of the Untitled CD as well.)

-------------------------------------------------------------------------------------------------

BURNING A DISC WITH DISK UTILITY

There are actually two ways to burn data to an DVD or CD with Disk Utility:

1.) Burn a disk in Disk Utility

* Simply open Disk Utility by either clicking anywhere on a blank space on your Desktop window and Finder will appear near your Apple menu, select Go >Utilities and that will take you to the Utilities Folder which is the default location of the Disk Utility application.

b90ce30.png


* Or you can click the Finder icon on your Dock, open a new Finder window, click on "Applications" listed in the side window and select the Utilities folder

a166fbd.png

d3fca75.png


* Either way, you will land here.

b417a9b.png


• Insert your CD or DVD.

9974e96.png


* Once you open Disk Utility, you will see this main window

a4997c2.png


* Now all you need to do is click the "Burn" button located on the Disk Utility toolbar.

3017d47.png


* For an example, I am striving to burn a copy of my Quicken .dmg file to CD.

* Once I have selected the file, then I click the Burn button located at the bottom right corner of the Finder window.

4773cc2.png

* Follow the onscreen instructions to start the burn process.

-------------------------------------------------------------------------------------------------

2. Creating a multi-session disk using Disk Utility:
Now it is known, that one cannot burn more than once with a single CD-R disc, but it can be done as provide from the knowledge base of Apple support:
  • In the Finder, create a folder for the session and drag the items you want to burn into the folder.
  • In Disk Utility, choose File > New > "Disk Image fromFolder." Then select the folder you created in the dialog and clickOpen.
  • Type a name for the image, choose a disk format, and click Save. Mac OS Extended allows burning the disc more than once. Formats such as ISO allow burning the disc only once.
  • When the disk image is complete, select it in the Disk Utility list and choose images > Burn or click Burn in the toolbar.
  • Insert a blank CD in the optical drive.
  • Select the "Leave disc appendable" checkbox. If you don't see this option, click the triangle in the top-right corner.
  • Click Burn.
What is really nice about this CD/DVD burn feature of DIsk Utility, is that now you can come back later and add more files to the same CD without having to waste all the space on a new CD-R.

This especially useful, if the image file you are need to burn is small in capacity. Just pop the previously burned CD in your drive and add that file or files until that CD is filled to capacity- that is all it takes.

-------------------------------------------------------------------------------------------------
So there you have it, a quick tip on how to use Finder and Disk Utility to burn any data to your CD and DVDs.

Thanks for viewing my Mac OS X tip from FixYa Support. Stay tuned for more tips for how to make the most of your Mac OS X systems!

Mac g5 wont start led light blinks once every 7 sec


Hold down the power button until the computer shuts off. The press the button to restart and see what happens. There are several different ways to startup. immediately upon hearing the boot tone, press and hold the shift key to boot in safemode. If this fails as well, then you will need to boot with the install CD. This is done by immediately pressing holding the C key upon powerup

Help to change new HD in Mac Mini PPC G4


If you are unable to boot from the CD's, and you are sure they are the CD's that are supposed to come with that model (the bundled CD's/DVD's are model specific), you may either have bad RAM or other damage to the logic board.
Try holding "D" when you try to start up from the discs instead of C, this should launch a hardware diagnostic utility. Run that, and see if it finds any other damage to the machine.

G5 failing to startup


Two things.  1. Boot from the original install disk and choose your language. Don't install the software, look up to the menu and find disk utility. You will run disk utility on your mac from the CD. You boot to the CD by holding down the "C" button during startup. 
2. If you had the insight to set up an emergency user, see if the problem occurs on both users. Sounds like it happens right off, so I think solution 1 is best. Once you get things running, set up another user. I call the account Emergency and use Emergency as the password. This is used for, you guessed it, emergencies. What this does is isolate the problem to the user or the computer. 
Apple has a great knowledge base to search for solutions as well. Good luck.

Is this a G5 2.7, dual 2.5 with a multicore processor using a liquid cooling system? If so open the case and check to see if any liquid is actually leaking. See xlr8yourmac.com for a whole bunch of postings on the issue.
