I have noticed the same problem as mentioned above (Joe's original post). When I boot up, my battery shows itself nearly full, or around 85% or whatever... then, very suddenly, it either gives me an almost- dead warning, or just plain shuts down. It doesn't appear that power is being consumed faster than before, but as if some specific action of Jaunty is suddenly sapping the power.
Since this is a fairly fresh Jaunty install, pretty sure I don't have any older kernels to roll back to, but here's the contents of my info file: present: yes design capacity: 4000 mAh last full capacity: 4000 mAh battery technology: rechargeable design voltage: 14800 mV design capacity warning: 420 mAh design capacity low: 156 mAh capacity granularity 1: 264 mAh capacity granularity 2: 3780 mAh model number: PA3383U serial number: 3658Q battery type: Li-Ion OEM info: TOSHIBA This is too odd to be a coincidence; I just upgraded to Jaunty last week, and I frequently used the laptop unplugged, so I know it's not a fluke. -- Battery Capacity Diminished After Jaunty Upgrade https://bugs.launchpad.net/bugs/354584 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
