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.

❑If the computer still does not turn on, follow these steps:

1 Unplug the power cord and remove the battery.

2 Use a thin, straight object (such as a paper clip) to press the reset button on the bottom of the computer. For location information, see “Locating Controls and Ports.”

3 Reinsert the power cord and the battery.

4 Turn on the computer.
