Maximizing Battery Operating Time
The battery operating time depends on your power management settings. Your Notebook components, the options, and the applications that you use also affect the operating time. This section of “Caring for Your Battery” shows you how to increase the length of time you are able to operate under battery power.
The display, processor, CD/DVD drive, and hard drive use the most battery power. To maximise the battery operating time, perform one or more of the following actions:
•Reduce display brightness and select a short wait for your screen saver.
•Select a screen saver that does not generate a lot of graphics or motion.
•Reduce audio volume or use headphones.
•Exit modem programs when you are not using them.
•Remove PC Cards when you are not using them.
•Remove CDs or DVDs when you are not using them.
•Use Sleep or Hibernation mode to turn off your Notebook when you are not using it.
