?? 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 notebook until the battery is fully 
discharged and the notebook goes into hibernation. 
3.  Connect the AC adapter and charge the battery to 100% with no power 
interruptions. 
To maximize processor speed 
If your notebook 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 its workload. See “How the notebook manages power 
automatically” on page 46.
