check the total power remains. Battery charging does not start until the power Meter shows that less

2. To check the status of your batter, move your cursor to the Power Meter icon in the icon tray of the
Windows taskbar and wait for a moment (but do not click), and the percentage of battery power
remaining is displayed. To get detailed information about the battery, double-click the Power Meter icon.
Note
If the battery pack becomes hot, it may not be able to charge. Remove it from the computer and
Leave it at room temperature for a while. After it cools down, reinstall and recharge it.
