Extending Battery Pack Operating Time Battery pack operating time can be extended by following these guidelines: s Select the High level of power conservation. See "Setting Battery Conservation Levels" in this chapter. s Initiate Suspend or Hibernation or turn off the computer when not in use for several hours. s Reduce the brightness of the display. s Select a shorter screen save timeout. s Avoid unnecessary fast-charge cycles, which reduce the cycle life of the battery. s Keep a battery pack in the computer when using it with external power to supply it with a constant charge. s When not in use, any external equipment without its own power source should be disconnected to avoid draining the battery pack. s Exit modem programs when not in use. s Remove the PC Card when not in use or turn off power to the PC Card slots. See Chapter 10, "Connecting External Devices," for more information about PC Cards. s Store the battery pack in a cool, dry place when not in use. High temperatures reduce the life of the battery pack and cause it to lose its charge more quickly. If you are storing the battery for less than one month, the recommended storage temperature is 32°F-122°F (0°C to 50°C); for no more than three months, the recommended temperature is 32°F-104°F (0 °C to 40°C); for an unlimited time, the recommended temperature is 32°F-86°F (0°C to 30°C). s Use the AC Adapter when possible. 5-12 Managing Power
