Chapter 5 Troubleshooting 57
If you have trouble ejecting a disc
 Quit any applications that may be using the disc and press the Media Eject key (C) 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 iMac G5 while holding down the mouse button.
If you have problems with your Internet connection
 Make sure your 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 port on the external modem and not the Ethernet port (G).
 See “Connecting to the Internet” on page 67 for information on setting up your
iMac G5 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
Setup Assistant to get your Internet account).
 See “Troubleshooting Your Connection” on page 81 for more information if you have
problems with your Internet connection.
If you have a problem using your iMac G5 or working with the Mac OS
 If the answers to your questions are not in this manual, look in Mac 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.
If your date and time settings get lost repeatedly
 You may need to have the internal backup battery replaced. The battery in your
iMac G5 is not user-replaceable. Contact an Apple Authorized Service Provider or an
Apple Store retail location for more information.

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 () > About This Mac
from the menu bar and then click More Info. Click the Hardware disclosure triangle to
view the serial number.
