Windows 10 normally displays a battery icon in the notification area, also known as the notification area, when you use a laptop or tablet. This icon indicates the current percentage of the battery. Here is how to recover it disappears.
Your battery icon may still be in the notification area, but "hidden." To find it, click the up arrow to the left of your notification icons on the taskbar.
If you see the battery icon here (an area that Microsoft calls the "notification area overflow pane"), drag and drop it into the notification area of your taskbar.
If you do not see the battery icon in the hidden icon panel, right-click on the taskbar and select "Taskbar Settings."
You can also go to Settings> Personalization> Task Bar.
Scroll down the Settings window and click "Enable or Disable System Icons" under Notification Area.
Locate the "Power" icon in the list here and toggle it to "On" by clicking on it. It will reappear on your taskbar.
You can also enable or disable other system icons from there, including Clock, Volume, Network, Input Indicator, Location, Center of Action, Touch Pad, Windows Ink Workspace and TouchPad.
If the Power option is dimmed, Windows 10 thinks you are using a desktop computer without a battery. The power icon on the taskbar will not appear on computers without a battery.
Even after you restore the battery icon, the remaining battery time estimate display is not displayed. Microsoft has disabled this feature, probably because it's usually inaccurate. You can still reactivate the estimate of the life of the battery with a registry hack.
