Computer
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.
3. Reinsert the power cord and the battery.
