Note: Press the Power button once briefly (up to one second). Holding down the Power
button as your computer starts up may shut down your computer again.
Problems Turning the Computer On?
Nothing happens when you press the Power button.
 The battery may be drained. Make sure that you plugged the power adapter firmly
into both the computer and a power source. The plug should light when you plug
it into the computer.
 If the computer still doesn’t start up, see “Problems That Prevent You From Using
Your Computer” on page 63.
You see a picture of a disk or a folder with a blinking question mark.
 This icon usually means that the computer can’t find the system software on the
hard disk or any disks attached to the computer. Try restarting. Hold down the
Power button for 4 to 5 seconds until the computer turns off. Then press the Power
button again. If the problem persists, you may need to reinstall the system
software. See “Reinstalling the Software That Came With Your Computer” on
page 67.
