Conserving the Battery Power
To conserve battery power on your laptop, do any of the following:
• Connect the computer to an electrical outlet when possible; battery
life is largely determined by the number of times the battery is used
and recharged.
• Configure the power management settings using Microsoft Windows
Power Options to optimize your computer’s power usage (see Setting
Power Options).
• Use the Sleep power state when you leave the computer unattended
for long periods of time.
