If you have installed Windows operating system on a netbook, notebook, tablet or desktop computer with Uninterruptible Power Supply (UPS), you probably are familiar with the small battery icon that appears in the system tray area of the taskbar.
The battery status icon comes very handy for users who don’t keep their notebooks or netbooks connected to the power supply always. Hovering the mouse cursor over the battery icon shows the remaining battery time and percentage.
Right-clicking on the battery icon provides quick access to Power Options, Windows Mobility Center, and Adjust screen brightness. One can quickly switch between power plans by clicking on the battery icon.
While this battery icon always appears in the system tray area of the taskbar, sometimes you might find that the icon is missing from the taskbar. If the battery icon isn’t appearing on the taskbar, you can try out the following solutions to restore the missing battery icon in Windows.
