Refer to Battery Tips for more information about how you can conserve battery power. Refer to Managing Power for information about how you can setup your computer to effectively manage power for your unique use patterns. Select Battery Calibration Managing Power Your computer has power management capability so you can reduce the amount of energy used, especially during periods of inactivity. Effective use of power management options can greatly conserve and extend your battery life. The power management unit monitors system activity, such as hard drive, keyboard, mouse, or any devices attached to a port. If it does not detect activity for a period of time, the computer stops some or all of these devices to conserve energy. Your computer employs a power management scheme that supports ACPI (Advanced Configuration and Power Interface), allowing for maximum power conservation and maximum performance at the same time. Windows handles all powersaving chores for your computer. For more information search for Power Options in Microsoft® Help and Support. General Dynamics Itronix | 72-0137-003
