[SOLVED] Battery disappeared

Suddenly, my battery disappeared (not physically but virtually).

- "acpi -b" gives no output at all.

- When I disconnect AC, my laptop instantly hibernates as laptop-mode is configured to do so at 0% battery charge. Hibernation completes successfully while obviously running on battery! Resuming with AC connected works.

It seems as if my battery is working but no longer detected  by the system.

Any ideas?

My guess is that you were using batterymon. Batterymon depended on hal and that is no longer supported. That's why the batterymon icon has disappeared. I encountered this problem myself and I just uninstalled batterymon and went with an alternative: batti (in Community repository). That works fine.

Hope this helps.

I have never used batterymon.

But... my battery just reappeared! :-)

I have not the slightest idea what has been going on. I restarted but I did that already before posting. Maybe some update (though I didn't noticed anything battery-related).

Thanks for your answers!

Re: [SOLVED] Battery disappeared

Sometimes this happens to me, too, and

rmmod battery
modprobe battery

fixes it.
