Troubleshooting Your Computer
Why doesn’t my computer start?
❑ Make sure the computer is securely plugged into a power source and is
turned on. Make sure the power indicator shows the power is on. See
“Connecting a Power Source” 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 then 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.
