I have (almost) the same problem. ACPI cannot find the battery after suspend.
I had the same problem with the fan also but it's much better now. There seems to be a problem with the temperatures that ACPI shows. They are fixed at certain points. When my laptop has been off for a long time and I boot it it the system monitor tells me that the temperature is 0 degres, then after a while it goes up to 27 or 28 i think then 48 and usually stays there. If I do something CPU intensive it may go as high as 55 or 68, always those fixed numbers. The fan follows those temperatures, so when it says 0 degres the fan does not spin at all and when it says 68 it goes really fast. I hope that made sense, I'm still quite a linux noob so please tell me if you need some information. -- Battery, suspend after resume broken, fan control is weird. https://bugs.launchpad.net/bugs/298927 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
