Well, i cannot find the power management to setup the battery settings,
There is one available as a "Panel Applet", I've tried it on my Dell Mini10v.
Right click on the panel and select "Add/Remove Panel Items". Click on the tab "Panel Applets" and you get a list of those currently installed, which you can re-arrange using the Up/down buttons. If you click on "Add" you will get a list of the additional applets that are available.
This includes a battery monitor, but it's not the best. You get a vertical bar which is green when the power is plugged in and yellow when running on battery. It's supposed to go red when the battery is almost exhausted and give you a five minute warning, but I've never got that low. My main beef is that this monitor always says 100% charged in yellow mode, even when I know from other monitors that it's only 50%.
There are other monitors available in the repo, I tried wmlaptop, and wmbattery, the first is more useful as it gives other info as well, but I have problems with these too. When installed, I started them by typing the name into the RUN box in the PC menu, but I don't know how to turn them off again!
A small (maybe 32x32?) window appears permanently in the upper left corner and won't go away! It also blocks other windows from using the columns of pixels below it, and overwrites any window you move into the same space.
It would be useful if it were less aggressive, but I don't know how to tame it. Can anyone help here?
