Installing files from Option Diskettes
An optional device or adapter might come with a diskette. Diskettes that are
included in option packages usually contain files that the system needs for
recognizing and activating the options. Until you install the necessary files, the
new device or adapter might cause error messages.
If your optional device or adapter comes with a diskette, you might need to install
some configuration (.CFG) files or diagnostic (.EXE or .COM) files from the
diskette to your hard disk. See the documentation that comes with the option to
determine if you need to install files.
Replacing the battery
Your computer has a special type of memory that maintains the date, time, and
settings for built-in features, such as serial and parallel port assignments
(configuration). A battery keeps this information active when you turn off the
computer.
The battery requires no charging or maintenance throughout its life; however, no
battery lasts forever. If the battery fails, the date, time, and configuration
information (including passwords) are lost. An error message is displayed when
you turn on the computer.
See “Lithium battery notice” on page vii for information about replacing and
disposing of the battery.
If you replace the original lithium battery with a heavy-metal battery or a battery
with heavy-metal components, be aware of the following environmental
consideration. Batteries and accumulators that contain heavy metals must not be
disposed of with normal domestic waste. They will be taken back free of charge
by the manufacturer, distributor, or representative, to be recycled or disposed of
in a proper manner.
To change the battery:
1. Turn off the computer and all attached devices.
2. Unplug the power cord and remove the cover. See “Removing the side
panel” on page 21.
3. Locate the battery.
4. If necessary, remove any adapters that impede access to the battery. See
“Installing adapters” on page 25 for more information.
