The battery recharges while it is installed and the computer is connected to AC power. While the battery is recharging, the battery charge indicator turns orange and the battery icon on the taskbar has a lightning bolt.
Closely monitor the battery charge. When the battery charge gets low, change the battery or connect to AC power immediately to prevent losing any unsaved work.
If the battery is not fully charged before you use the computer on battery power for the first time, the battery life may be much shorter than expected. If the battery life seems short even after being charged for 24 hours, the battery may need to be recalibrated.
