What should I do if my computer won't start?
Make sure the computer is securely plugged into a power source and turned on. Make sure the power indicator shows
the power is on.
Make sure the optical disc drive (if applicable) is empty.
If the computer is plugged into a power strip or uninterruptible power supply (UPS), make sure the power strip or UPS is
plugged into a power source and turned on.
Make sure the brightness and contrast controls are adjusted correctly.
Condensation may cause the computer to malfunction. If this occurs, do not use the computer for at least one hour.
Remove any extra memory modules you may have inserted since purchase.
Confirm that the computer is not in Standby mode by pressing any key on the keyboard.
