           Summary: Battery not seen by acpi until I plug the ac adapter in
                    and out
    Kernel Version: 2.6.16-rc5
            Status: NEW
          Severity: normal
             Owner: [EMAIL PROTECTED]
         Submitter: [EMAIL PROTECTED]


Most recent kernel where this bug did not occur: -
Distribution: Gentoo
Hardware Environment: Nec Versa P550
Software Environment: Unstable gentoo install
I have full ACPI support in my kernel, if I boot my pc from battery or ac
adapter I get: ACPI: Battery Slot [BAT1] (battery absent) in my dmesg. If I plug
in my ac, and then out again ( or out in out if it was in ) then the battery is
detected. It is a NEC Versa P550 btw. It knows there can be a battery in it, as
/proc/apci/battery/BAT1/state is there. Just says there's no battery there when
there is.

Reproducible: Always
Steps to Reproduce:
1. Compile kernel with acpi
2. Boot
3. have a look at /proc/acpi/battery/BAT1/state

Actual Results:  
battery absent

Expected Results:  
batteyr should be detected
