The battery monitor widget in Mageia 1 seems to have problems.
(1) When left-clicking on the battery monitor, the panel that appears doesn't look right and isn't useful for functionality (see attachment)
(2) Earlier today, I had a notification saying that I was low on battery power, when the battery monitor still showed 89%. Perhaps there is an issue with updating the charge level, but I haven't tried this again yet.
BTW: When I left-click on the Notification widget, I also get similarly useless bars as in the screenshot. Perhaps this is something about several widgets.
