Every time during the F9 cycle, there have been no warnings that I'm about to run out of battery, and the machine just dies - i.e. no suspend, no hibernate - it just up and dies. There *has* been a warning that the battery might be defective, it can only hold a 48% charge, so something is reading the battery correctly (I don't have a hard time believing that, the battery is about 18 months old and the machine is plugged in most of the time). I'm sure there's more info required here, but I'm going to start with an lshal from the machine in question.

Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Bug #448362 describes a similar issue but doesn't mention possibly defective hardware. I am under the impression that both bugs may be caused by gnome-power-manager not trusting its battery profile either because it hasn't gone through enough learning cycles (Bug #448362) or because the hardware doesn't permit completing a learning cycle (this bug).
Does this still happen with the version in fedora rawhide, or the version of the Fedora 11 beta live cd?
this morning I boot my rawhide with only 3% of battery left, after opening some apps in Gnome, it switch off automatically without any warning. Power cord was plugged.
Seeing same behavior on FC10, no warning other than taskbar icon prior to shutdown.
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '9'. 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 9'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 9 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
