Ok - this behavior really blows. I have an HP NC8000 laptop with 2 batteries and the behavior is the same as mentioned above. Here is how I can reproduce the problem using Ubuntu 8.10 32 bit (Intrepid):
1.) Charge both batteries to 100% 2.) Unplug AC and double-click on battery icon. Both batteries show 100%. 3.) Observe for 5 minutes and double-click on battery icon again. 4.) Internal battery still shows 100% but secondary (removable battery) shows 95% 5.) Observe for over an hour and secondary battery continues to discharge until critical battery warning is triggered. 6.) Unless I change the Power Management preferences to disable Turn Off action when battery level is critically low, the laptop will power-off with little to no warning. 7.) If I unplug the secondary (removable) battery, Ubuntu will automatically switch to the primary battery. This "workaround" is not desirable - Ubuntu should either draw from both batteries at the same time or use one and then switch to the second automatically, this would be preferable. Note: I also tested this behavior with 2.6.28 with the 2.6.29-rc7 patch applied to the kernel. The behavior is the same. Please let me know what logs I should attach to help isolate/identify the source of this problem.
