VAIO® Computer Quick Start

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.

the screen. Follow these steps:
