In addition to your computer's automatic power management, you can
do your part to maximize the battery's operating time by following
l Do not disable Power Management.
l Decrease the LCD brightness to the lowest comfortable level.
l Disable the parallel and serial ports if no devices are connected to these
ports. (See "Advanced Menu" in Chapter 5.)
l If you work with an application that uses the serial port or a PC Card, exit
the application when you finish using it.
l If you have a PC Card installed, remove it when not in use. Some PC Cards
drain power even while they are inactive.
l Turn off the computer when you are not using it.
