Troubleshooting

What should I do if my computer does not start?

❑ Make sure your computer is securely plugged into a power source and

turned on and the power indicator light is lit.

❑ Make sure the battery pack (if applicable) is installed properly and

charged.

❑ Make sure the floppy disk drive (if applicable) is empty.

❑ If your computer is plugged into a power strip or an uninterruptible power

supply (UPS), make sure the power strip or UPS is plugged into a power

source and turned on.

❑ 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

more information.

❑ Unplug the power cord or the AC adapter, and remove the battery pack

(if applicable). Wait three to five minutes. Reinstall the battery pack (if

applicable), plug the power cord or the AC adapter, and then press the

power button to turn on your computer.

❑ Condensation may cause your computer to malfunction. If this occurs, do

not use the computer for at least one hour.

❑ Remove any extra memory modules you may have installed since

purchase.

❑ Check that you are using the supplied Sony power cord or AC adapter.

For your safety, use only the genuine Sony rechargeable battery pack (if

applicable) and power cord or AC adapter, which are supplied by Sony

for your VAIO computer.
