Summary: Battery state not reported correctly
Product: ACPI
Version: 2.5
Kernel Version: 2.6.24-rc5-19-pae
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Battery
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: No
At boot:
When I boot up without the battery in my laptop the kernel reports that the
battery is still there and that it is empty (charged at 0%). Coming back from
suspend to ram or suspend to disk will cause the detection that the battery is
not present.
Also:
When it is AC adaptor-no battery state is correctly detected, if i go to
suspend, insert the battery, disconnect the adaptor, and come back from
suspend, kernel doesn't detect the new battery-only state. Pluging and
unplugging the AC adaptor fixes it.
This problem has been happening for as long as i can remember (2.6.27...?). The
main implication concerns that the power-saving mechanisms are not turned on
when the battery presence is misdetected.
Let me know if i can be any help attaching other infos...
