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 connected 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 guide that came with your display for details.
❑ Remove the AC adapter and battery. Wait one minute. Reattach the AC
adapter and reinsert the battery, and turn on the power.
❑ Condensation may cause the computer to malfunction. If this occurs, do not
use the computer for at least one hour.
❑ If the computer still does not turn on, follow these steps:
1 Unplug the power cord and remove the battery.
2 Use a thin, straight object (such as a paper clip) to press the reset button.
See “Locating Controls and Ports” in the printed Quick Start to locate
the reset button.
3 Reinsert the power cord and the battery.
4 Turn on the computer.

the screen. Follow these steps:
1 Press F2. The BIOS Setup menu appears.
2 Set the date (month/day/year). Press Enter.
