 Troubleshooting

 

Quit any applications that may be using the disc and press the Media Eject key (

) 

on your keyboard.

If that doesn’t work, open a Finder window and click the eject icon next to the disc 
icon in the Sidebar, or drag the disc’s icon from the desktop to the Trash.

If that doesn’t work, restart the computer while holding down the mouse button.

Make sure your telephone line or network cable is connected and functioning 
properly.

If you are using a dial-up Internet connection, make sure that your telephone cord is 
plugged into the modem port (marked with the icon W) and not the Ethernet port 
(marked with the icon G).

See “Connecting to the Internet” on page 69 for information on setting up your 
computer to connect to the Internet. There you will find how to locate your Internet 
settings and the contact information for your Internet service provider (if you used 
the Setup Assistant to get your Internet account).

See “Troubleshooting Your Connection” on page 85 for more information if you have 
problems with your Internet connection.

If the answers to your questions are not in this manual, look in Mac OS Help for 
instructions and troubleshooting information. In the Finder, choose Help > Mac Help.

Check the Apple Support website at www.apple.com/support for the latest 
troubleshooting information and software updates.

You may need to have the internal backup battery replaced. See “Replacing the 
Internal Backup Battery” on page 51 for more information.

Locating Your Product Serial Number

You can find the serial number for your iMac G5 on the bottom of the stand. You can 
also use System Profiler to find the serial number. Choose Apple (K) > About This Mac 
from the menu bar and then click More Info. Click the Hardware triangle to view the 
serial number.
