 Wait a few seconds. If the computer doesn’t soon start up, shut it down by holding
down the power (®) button for about 8 to 10 seconds. Disconnect all external
peripherals and try restarting by pressing the power (®) button while holding down
the Option key. When your computer starts up, click the hard disk icon, and then click
the right arrow. After the computer starts up, open System Preferences and click
Startup Disk. Select a local Mac OS X System folder.
 If that doesn’t work, try using Disk Utility to repair the disk:
 Insert the Mac OS X Install DVD into your computer.
 Restart your computer and hold down the C key as it starts up.
 Choose Installer from the menu bar, and then choose Open Disk Utility. When Disk
Utility opens, follow the instructions in the First Aid pane to see if Disk Utility can
repair the disk.
If using Disk Utility doesn’t help, you might need to reinstall your computer’s system
software. See “Reinstalling the Software That Came with Your MacBook” on page 51.
If your MacBook doesn’t turn on or start up
Try the following suggestions in order until your computer turns on:
 Make sure the power adapter is plugged into the computer and into a functioning
power outlet. Be sure to use the 60W MagSafe Power Adapter that came with your
MacBook. If the power adapter stops charging and you don’t see the indicator light
on the power adapter turn on when you plug in the power cord, try unplugging and
replugging the power cord to reseat it.
