Hard disk
The computer won’t start up from the internal hard disk, or the hard disk icon doesn’t appear on the desktop.
mThere may be a temporary software problem. Turn off the computer, wait at least 10 seconds, and then turn it on again.
The hard disk keeps stopping and starting again.
mThe hard disk may be going to sleep to conserve power. Use the PowerBook control panel to change the power conservation settings.
The computer is using the wrong disk as a startup disk.
mOpen the Startup Disk control panel and make sure the correct disk is selected. Then restart the computer.
mIf you’re trying to start up from an external hard disk, the computer may not be recognizing the disk. See “SCSI Equipment and SCSI Disk Mode”
later in this section. (If you want to force the computer to start up from an external hard disk, hold down the Command (x), Option, Shift, and Delete keys while you restart. This procedure makes the computer bypass the internal hard disk when looking for a startup disk.)
mThere may be a problem with your startup disk or with its system software. See “Testing Your Hard Disk” in Chapter 8.
Trackpad
The pointer won’t move.
mA program may be doing some work. Wait a few moments and then try again.
mA temporary software problem may have caused the computer to “freeze.” See “The Computer Freezes or Displays a System Error Message” in the section “Problems Working With Programs,” earlier in this chapter.
The pointer sticks or jumps when I use the trackpad.
mMake sure to use only one finger on the trackpad and that your finger is dry.
