Hello, Firstly I would like to say that I don't really know if this is the correct mailing list to discuss this issue. If it isn't, would you be so kind to point me in the right direction? I would like to ask you whether you are dealing with the battery detection issues present in Karmic. These issues are a regression from Jaunty, at least in my case. Here are some bug reports related with this: <a href="https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/381242" target="_blank">https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/381242</a> <a href="https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/393008" target="_blank">https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/393008</a> <a href="https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/386778" target="_blank">https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/386778</a> <a href="https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/442378">https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/442378</a> (my issue) On Karmic, when I booted using battery power, the system recognised it as being battery power. On Karmic, it says I'm on AC, and therefore none of the battery actions trigger. To make it detect the battery, I need to plug the pc to AC, kill gnome power manager, restart it, etc. I think this is a serious issue that can cause data loss. Apart from that, there is no indication the laptop is using its battery, nor any estimated time left for the user to decide to plug/shutdown it. Looking forward to hearing from you, Emilio
