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.
