Troubleshooting
Â
Make sure you are within antenna range of the other computer or the network’s
access point by checking the AirPort Extreme or AirPort Express signal level. Check
the AirPort status icon in the menu bar. Up to four bars appear to show signal
strength.
Nearby electronic devices or metal structures can interfere with wireless
communication and reduce this range. Repositioning or rotating the computer might
improve reception.
Â
See AirPort Help (choose Help > Mac Help, then choose Library > AirPort Help from
the menu bar) and the instructions that came with the wireless device for more
information.
If your computer’s hard disk is not recording data correctly
Â
In a few instances, if the hard disk undergoes unusually strong vibration, the Sudden
Motion Sensor might become active and cause dropped frames or unrecorded
portions of sound or data when the disk is recording intensively. If this occurs, make
sure that your PowerBook is in a stable environment without vibration or abrupt
movement.
If you have trouble ejecting a disc
Â
Quit any applications that might be using the disc and try again. If that doesn’t work,
restart the computer while holding down the trackpad button.
If you suspect a problem with your computer hardware
Â
You can use the Apple Hardware Test application to help determine if there is a
problem with one of your computer’s components, such as the memory or processor.
For more information about Apple Hardware Test, see “Using Apple Hardware Test” on
page 69.
If you have problems with your Internet connection
Â
Make sure your phone line or network cable is connected and functioning properly.
Â
If you are using a dial-up Internet connection, make sure that your phone cord is
plugged in to the modem port (
W
) and not the Ethernet port (
G
) on the computer.
Â
Open the Network pane of System Preferences and verify the information entered
there with your Internet service provider (ISP) or network administrator.
If you have a problem using your computer or working with the Mac OS
Â
If the answers to your questions are not in this manual, choose Help > Mac Help
from the menu bar and search for instructions and troubleshooting information.
