KDE battery monitor not detecting laptop battery

I am using KDE on my Dell XPS laptop. The default battery monitor that comes with KDE installation is not detecting the laptop battery. It is showing "Battery: Not Present". Because of this I am unaware about the time remaining on my battery. Any solutions please?

I'm having this same problem. For the time being I'm using:

Same problem here with a Dell XPS too. The thing is it used to work some months ago, but now it's broken.

Re: KDE battery monitor not detecting laptop battery

Have you tried rebooting *twice*? I've seen this issue but I've always resolved it by rebooting and then rebooting again. (The system goes rather insane on the first reboot and I always think either my hardware is completely screwed or my install of Arch is twisted far beyond the point of insanity. But then on the second boot, it calms down, finds the hardware and carries on quite happily. I've no idea why.)

Re: KDE battery monitor not detecting laptop battery

Actually it seems that the problem is that it only read the battery state when I log in. If I log in with the battery inserted, it detects it. But if I remove it, it doesn't detect that it's been removed (and the other way around, if the battery is not present at log in, when I insert it in won't get detected).
