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 charged and inserted properly.
❑ If you the computer is 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 guide that came with your display for details.
❑ Remove the battery from the computer, unplug the power cord, and plug the
power cord in again. Turn on the power.
❑ If the computer does not turn on, 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 using a thin, straight object
(such as a paper clip). Remove the battery if one is installed, and plug the
power cord in again. Turn on the computer. To find your computer’s reset
button, see “Locating Controls and Ports” in the “Setting Up” chapter of
your supplied VAIO® Quick Start.
Why does a BIOS error appear when my computer starts?
When the battery is low on power, your system may not start properly. The
message “Press <F1> to resume, <F2> to setup” may appear at the bottom of the
screen. Follow these steps:
1 Press F2. The BIOS Setup menu appears.
2 Set the date (month/day/year). Press Enter.
