What do 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 battery is inserted properly and charged.
❑ Make sure the floppy disk 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 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 guide that came with your display for details.

Reattach the AC adapter and reinsert the battery. Turn on the power.
❑ Condensation may cause the computer to malfunction. If this occurs, do not
use the computer for at least one hour.
