You should also recalibrate the battery periodically to maintain the accuracy of the battery gauges. To recalibrate the battery: 1 Connect the AC adapter, then turn on your notebook. 2 As soon as it starts and you see a startup screen, press F2. The BIOS Setup utility opens. 3 Open the Advanced menu. 4 Highlight Battery Auto Learning, then select Enabled by pressing the spacebar. 52
