Power and Your Computer
2–13
12X CD-ROM/FDD Drive
Floppy Disk (FDD) and CD-ROM drives consume a large amount of battery power. In
order to maximize battery run time, use the 12X CD-ROM/FDD Combination module
only when necessary.
PC Cards
PC (PCMCIA) Cards will also tax your battery power, significantly reducing run time.
When operating the notebook on battery power, use PC Cards as little as possible.
When you finished using your PC Card, eject it from the PC Card slot. This extends
battery run time.
The Serial/ Infrared Port
The computer’s serial ports will draw some power if Enabled, even though no serial
device is connected. If you are not using a serial device, disable the port through the
BIOS program. This will assist in conserving battery power. Please see Chapter 3 for a
complete discussion on enabling and disabling the notebook’s ports.
AC Power
The most obvious way to conserve battery power is to avoid using the battery when there
is an available AC power source. The AC Adapter is lightweight and compact, so it is
very convenient to bring while traveling. By using the AC Adapter as much as possible,
you can ensure you will have a charged battery whenever you really need it.
