Batteries and Power Management
Using Battery Power
56 Corporate Evaluator’s Guide
In addition, follow these suggestions to extend the life of your batteries.
•
Do not leave batteries unused for long periods. If you have more than one, rotate
them.
•
If you normally use AC power, make a practice of using the battery as your power
source at least once a week.
•
Unplug the AC adapter when the computer is not in use.
•
To preserve the life of a battery, be sure to charge it regularly.
•
For long-term storage, the battery must be charged 20–50% to minimize capacity loss
by self-discharge and to avoid deterioration of performance. Storing a fully charged
battery can cause higher self-discharge and reduce its discharge capacity—even after
recharging—as compared to a battery stored when charged 20–50%.
•
To maintain maximum battery capacity and accuracy of the battery gauge, perform
this procedure about once a month:
1. Charge the battery to 100%.
2. Disconnect the AC adapter, and use the computer until the battery is fully
discharged and the computer goes into hibernation.
3. Connect the AC adapter and charge the battery to 100% with no power
interruptions.
To maximize processor speed
If your computer contains a multispeed processor with Intel SpeedStep Technology, the
processor can automatically switch to lower, power-saving speeds or to higher-
performance speeds according to the workload. See “How the computer manages power
automatically” on page 50.
