Computer Operations

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 is installed properly and charged.

❑ Disconnect all connected USB devices (if any), and then restart your computer.

❑ Remove any extra memory modules you may have installed since purchase, and then restart your computer.

❑ 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 AC adapter and remove the battery pack. Wait three to five minutes. Reinstall the battery pack, plug 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.

❑ Check that you are using the supplied Sony AC adapter. For your safety, use only the genuine Sony rechargeable battery

pack and AC adapter, which are supplied by Sony for your VAIO computer.
