Troubleshooting Your Computer
My computer does not start.
 Make sure the computer is plugged into a power source and is turned on.
 Make sure the power indicator shows the power is on.
 Make sure the battery packs are inserted properly and are 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.
 Make sure the power cord and all cables are connected firmly. See "Connecting a Power Source" for more
information.
 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.
 Take the battery pack off 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 pack. Wait one minute, and
reattach them. Press 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 pack, plug it in again and turn on the power.
