Page 80 highlights

Power When to Calibrate Even if a battery pack is heavily used, calibration should be necessary only once a month. You do not have to calibrate a new battery pack. Calibration does not usually increase battery run time, but it can increase the accuracy of battery charge displays, especially under the following conditions: ■ When the battery pack has been unused for one month or more. ■ When you notice a significant change in battery run time. ■ When the battery charge displays seem inaccurate. For more information about battery charge displays, refer to the "Monitoring the Battery Pack Charge" section earlier in this chapter. How to Calibrate To calibrate a battery pack, you must fully charge, fully discharge, and then fully recharge the battery pack while the computer is running Windows. Step 1: Charging the Battery Pack Charge the battery pack while the computer is on. To charge the battery pack: 1. Insert the battery pack into the computer. 2. Connect the computer to the AC adapter, an optional power adapter, or an optional expansion product, and then plug the adapter or device into external power. (The computer battery light is turned on.) 3. Leave the computer connected to external power until the battery pack is fully charged.
