Description of problem: Powertop reports absurd numbers for battery discharge rate Version-Release number of selected component (if applicable): powertop-1.98-4.fc16.x86_64 The battery reports a discharge rate of 12.6 kW How reproducible: Always Steps to Reproduce: 1. Start powertop 2. 3. Actual results: On a Dell Latitude E6520: (w/ Bios A08) With mains power connected: The battery reports a discharge rate of 12.6 kW With the power adapter unplugged: The battery reports a discharge rate of 13.6 MW Other data from powertop looks plausible. Expected results: Either correct numbers, or, when impossible, no numbers at all, but not something blatantly absurd. Additional info:
Please provide output of: # for d in /sys/class/power_supply/*; do echo $d; cat $d/uevent; done for both cases.
Wow, that is fast response ...

Please could you check the following scratch build and let me know if it fixes your problem? http://koji.fedoraproject.org/koji/taskinfo?taskID=3863861
It reports now: With mains power connected: The battery reports a discharge rate of 12.6 mW With the power adapter unplugged: The battery reports a discharge rate of 13.5 W So, the same numbers apart from a factor 1e6. I guess the issue is solved. Thanks 1e6 :)
Thanks for info, I will push it.
