Computer
What should I do if my computer does not start?
❑
Make sure your computer is securely plugged into a power source and turned on.
Make sure the power indicator shows the power is on.
❑
Make sure the battery pack 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.
❑
Disconnect the AC adapter and remove the battery pack. Wait three to five minutes.
Reinstall the battery pack, reattach the AC adapter, and then press the power button
(slide up the power switch on VGN-UX series models) 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.
❑
On all models except VGN-UX series and VGN-TZ series models, remove any extra
memory modules you may have installed since purchase.
❑
Check that you are using the supplied Sony AC adapter. For your safety, use only
genuine Sony rechargeable battery packs and AC adapters, which are supplied by
Sony for your VAIO computer.
