Turn on the computer and complete setting up the operating system. Operate the computer using battery power. Reconnect the AC adapter and fully charge the battery again. Follow these steps again until the battery has been charged and discharged three times. 48 - Battery pack Use this conditioning process for all new batteries, or if a battery hasn't been used for a long time.
