Startup Problems
If the computer doesn’t respond when you turn it on
• Connect the AC adapter.
• Try turning on the unit by pressing the blue sleep button.
• Reset the computer by inserting a straightened paper clip into the system-off switch
on the left side of the computer. Then turn it on by pressing the blue sleep button.
• Don’t touch the pointing stick while booting or resuming.

PC Card, and undock the computer if docked. Then plug the AC adapter in, reset the
computer using the system-off switch, and turn it on by pressing the blue sleep button.
