Conserving battery power
How long a fully charged battery lasts when you are using the
computer depends on a number of factors, such as:
❖
How the computer is configured
❖
How much you use the display panel instead of an
external monitor
❖
How much you use the hard disk and other drives
❖
Whether you use any optional devices to which the
battery supplies power, such as a PC Card
❖
Where you are working—since operating time decreases
at low temperatures
