Hi,
I have SuSE 9.1 Professional on Thinkpad T42p which I run with two batteries - the main at the back and an extra one in the CD/DVD drive bay. I like to keep an extra battery instead of the CD/DVD drive.
The problem is that kpowersave does not display the status of both the batteries. I can only see the status of one battery.
No, you should see the overall percentage of both batteries. If not - it's a bug of powersaved.
Ideally, I would like to see two battery charge displays.
Feature request taken.
The Laptop Battery control module in Kcontrol does show both batteries and their charge status correctly (so ACPI is reporting them correctly).
Powersaved combines all battery charge levels by doing charge = (charge1+charge2)/(capacity1+capacity2) (this is from memory, but it should be correct). With "powersave -B" you can get the charge status of both batteries separated, but it is not possible in the kpowersave applet yet. Technical background: the applet just asks the daemon for charge status and the socket interface for multiple batteries is not implemented yet, so kpowersave cannot display multiple batteries. The KDE Laptop Battery applet does direct reading of /proc/acpi/battery which on some machines is not desirable (high system load, some machines have keyboard problems when reading these pseudo files too often etc.) and calculates the values from there. So it is a trade off and you have to decide for yourself which one to use. -- Stefan Seyfried
