Understanding the KPowersave Icon

The KPowersave icon looks like a power plug next to a battery strength indicator. The icon shows the current battery strength and whether the computer is powered by the battery or the power supply. When the battery power is low, the background of the icon flashes, orange for Warning and red for Low or Critical. If you leave the mouse cursor over the icon, a message shows whether the computer is plugged in or using the battery, the current charge level of the battery, and, if the computer is running on battery power, the approximate amount of time left before the battery power runs out.
