Description Aurelijus 2013-10-25 21:17:24 UTC
Battery monitory sees only battery 1. However, here is the output of upower:
$ upower -e

    1382734709  5.745   charging

Obviously, two batteries are present and computer sees it.



Minor remark: the bug has been introduced roughly 1-1.5 years ago, don't remember when but it was working long time ago.

Reproducible: Always

Steps to Reproduce:
1. Plug in extension battery pack.
2. Run upower to cross-check.
3.
Actual Results:  
I saw that the battery monitor does not see my second battery.

Expected Results:  
Both batteries are visible.

Can you use plasmaengineexplorer (comes with plasmate) and check what the powermanagement dataengine says, ie. if both batteries are present there?
Comment 2 Aurelijus 2013-10-26 20:39:06 UTC
If I launch plasmaengineexplorer and select Data Engines -> powermanagement there I see three entries: Battery, Battery0, and Battery1. Here Battery1 appears to be the secondary battery.

Sorry, I misread your bug report. This is a known issue unfortunately.
