Or, how to both see battery level and hibernate normally? At the moment it seems I have only discovered how to do one or the other for one system running 2.6.21-1.3228.fc7. As installed, this system hibernates and resumes correctly with no need for any quirks. But neither Power Manager 2.18.3 nor Battery Charge Monitor 2.18.0 properly detect the battery (e.g. Battery Charge Monitor 2.18.0 hover text includes "No battery present"). Yes, the system will run normally on its battery (e.g. dimming the display slightly, beeping as AC power is removed and restored) except there is no hint as to whether the calculated capacity estimate is for another 1.5 minutes or 1.5 hours of runtime. If the boot line in Grub is edited to include "acpi=off apm=on" then either battery monitor application behaves as expected. But when one hibernates, the eventual reward ends with: Synchronizing SCSI cache for disk sda Power down Synchronizing SCSI cache for disk sda and then it just sits there forever. If one then pushes the Power button, the system turns off, and later one can Resume it without any detected problem. But the user should be able to hibernate without hanging around for another while to push the power button at the end; and know the state of charge in the battery, too, in the same configuration. Are there other options or switches I need to discover? I happened to notice that: http://lists.freedesktop.org/archives/hal/2007/-june/008857.html mentions adding battery and ac_adapter objects in the HAL device tree. I am not yet aware of any HAL quirk support for batteries in Fedora 7.
