Comment 2 for bug 130739

Confirmed.

It took me a while, but I was finally able to duplicate the problem.
Three Observation:

1. I've noticed that on my daru2, the icon does not start switching between a/c and battery until the battery is fully charged. Once it starts, though, it will not stop, even after the battery has discharged a bit.

2. The applet seems to correctly detect whether A/C or battery is being detected until it starts acting up. It is, however, very slow in showing a change in state. Sometimes it can take up to 30 seconds.

3. There is often a discrepancy in the readings of the applet and the readings of $acpi.
