Battery Packs and Power Management

To Get the Most from Your Battery Packs

Follow these suggestions to make your battery power last as long as possible:

■Plug in the AC adapter, especially when using a CD-ROM or DVD drive, or any external connections such as a PC Card or a modem.

■Set the display brightness to the lowest comfortable level (Fn+F1).

■Put the notebook in Standby when you will not be using it for a short while.

■Put the notebook in Hibernation whenever you want to save your current session but will not be using the notebook for a day or more.

■Set the automatic timeout settings to emphasize saving power. If your notebook has a multispeed processor, use the lower speed on battery power (the default settings conserve battery power).

■If your notebook has a wireless on-off button, turn off the wireless function when you are not using it. Press the wireless on-off button to turn off the light.

■If you have a PC Card, such as a network card, remove it when you are not using it. Some PC Cards use significant power even while they are inactive.

■If you work with an application that uses the serial port or a PC Card, exit the application when you finish using it.
