About Battery Calibration
Battery calibration may take up to 12 hours to complete. After
starting calibration, the application requires no further input
from the user. During calibration it goes through three steps:
1.
Charge - the battery is fully charged to 100 %.
2.
Discharge and calibrate - the battery is discharged to zero,
then calibrated but not charged. You may stop the process
after this point and let the battery charge outside of the battery
calibration application.
3.
Charge - if battery calibration continues running, the battery
will fully charge to 100%.

Refer to Battery Tips for more information about how you
can conserve battery power. Refer to
information about how you can setup your computer to
effectively manage power for your unique use patterns.
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 power-
saving chores for your computer.
