Important Notes on Using a Battery Pack Recharging and Discharging • Recharging will not start if the battery's temperature is below 0°C (32°F) or above 45°C (113°F) for NiMH batteries and 40°C (104°F) for Li-ion batteries. Also, during recharging, the recharging will stop if the battery's temperature gets above 60°C (140°F). To avoid problems caused by temperatures, make sure the battery is not too hot before you begin to recharge or discharge the battery. Follow these general guidelines: − When the battery is being recharged, keep the notebook power off and wait until it is fully recharged to achieve the fastest charge times. − When the battery is fully charged or discharge, allow a brief cooling interval to maintain the charge capacity and extend the useful life of the battery. • During recharging, in order to maintain fuel gauge accuracy, do not disconnect the AC adapter before the battery has been fully charged. • After the battery has been fully recharged, do not repeatedly disconnect and reconnect the AC adapter to charge the battery again. Doing so may damage the battery pack or reduce its charge capacity and useful life potential. • Do not leave the battery completely discharged for too long as this may affect the battery's performance. • A DOS utility named "4dischrg.com" is included on your Utility CD-ROM. It is used to disable all system power saving functions and allow you to calibrate the battery fuel gauge. Before running this utility, it is important that you save all files and close all applications. Problem Solving • If the difference between the actual operating time of a battery and the expected operating time is too large, you can fully discharge and recharge the battery several times to solve the problem. 3-4 Battery Operations
