Troubleshooting Your Computer
Why doesn't my computer start?

Make sure the computer is securely plugged into a power source and is on. Make sure the power indicator shows
the power is on. See
Connecting the AC adapter for more information.
 Make sure the battery is inserted properly and is charged.
 If you are connected to a docking station with a floppy disk drive or an external floppy disk drive, make sure the
floppy disk drive is empty.

If the computer is plugged into a power strip or Uninterruptible Power Supply (UPS), make sure the power strip or
UPS is turned on and working.
 If you are using an external display, make sure it is plugged into a power source and turned on. Make sure the
brightness and contrast controls are adjusted correctly. See the manual that came with your display for details.
 Remove the battery from the computer, unplug the power cord, and plug it in again. Turn on the power.

If the power control button does not function, remove the AC adapter and battery. Wait one minute, and reattach
them before pressing the power button.

Condensation may cause the computer to malfunction. If this occurs, do not use the computer for at least one hour.
 Unplug the power cord, press the reset button by using a thin, straight object (such as a paper clip), remove the
battery, plug it in again, and turn on the power.
