Created attachment 575830 [details] Power Statistics window showing large deviations in discharge accuracy Description of problem: The UPower component in the latest releases, including Fedora 15 and Fedora 16, provides incorrect and fluctuating information on the amount of remaining battery back-up time when the laptop is running on battery. My laptop is a Dell Inspiron 1545 with an original Dell 9-cell battery pack. The amount of available battery time shown keeps varying from around 7 hours (not possible on my system) to around 2 hours, at almost all times, no matter what the battery level. However, it tends to get more accurate as the battery drains. Correct information is almost never shown when the battery charge is more than 50%. Version-Release number of selected component (if applicable): 0.9.15-1.fc16 (x86_64) How reproducible: Always Steps to Reproduce: 1. Log in to a Fedora 16 installation on a Dell Inspiron 1545 on battery power. 2. Check the amount of remaining battery back-up time shown. Actual results: Amount of time shown is incorrect. Expected results: Amount of time shown is correct. Additional info: I know that this is a bug in UPower or some such upstream component because the problem occurs consistently on all the latest Linux distributions irrespective of other components such as the kernel, and it did not occur in earlier distributions (more than approximately 18 months old) which either used older versions of UPower or used HAL instead of UPower.
This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 16 changed to end-of-life (EOL) status on 2013-02-12. Fedora 16 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
