A:Answer In order to improve or prolong the battery charged time, please try to do a battery calibration manually. To start with, please drain it completely then charge it fully without using the system. Once fully-charged, please use the laptop, without the AC adapter connected, and drain let the battery drain completely again. Please repeat the charging process thereafter. Also, please verify if the laptop is running with the most current system update and third-party battery draining applications are not running if not in used.
