This section provides instructions on how to replace the battery.
Your computer has a special type of memory that maintains the date, time, and settings for built-in features, such as parallel-port assignments (configuration). A battery keeps the information active when you turn off the computer.
The battery normally requires no charging or maintenance throughout its life. However, if the battery fails, the date, time, and configuration information (including passwords) are lost. An error message will be displayed when you turn on the computer.
Remove all media from the drives and turn off all attached devices and the computer. Then, disconnect all power cords from electrical outlets and disconnect all cables that are connected to the computer.
Place a soft, clean towel or cloth on the desk or surface. Hold the sides of your computer and gently lay it down so that the screen is against the surface and the cover is facing up.
