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.
❑Disconnect the AC adapter and remove the battery. Wait one minute. 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.
