3-10 Managing Power
Power-Saving Tips
In addition to your computer’s automatic power management, you can do
your part to maximize the battery’s operating time by following these
suggestions.
Do not disable Power Management.
Decrease the LCD brightness to the lowest comfortable level.
Disable the parallel and serial ports if no devices are connected to
these ports. (See “Advanced Menu” in Chapter 5.)
If you work with an application that uses the PC card or features
wireless connectivity (LAN/modem/GPS), exit the application when
you finish using it.
If you have a PC card installed, remove it when not in use. Some PC
cards drain power even while they are inactive.
Turn off the computer when you are not using it.
