Let me see DSDT (/proc/acpi/dsdt) , and check whether it is a real bug
or
 just short of words.

I can't say for certain, but I think it's a tad confused - it can report 
'charging', and 'discharging', but doesn't know what to say if the battery
is at 100% and you're running off AC....It's been that way on mine at
least since 2.5.7mumble or maybe 2.4.18, so it's NOT a regression from the
recent ACPI patch.

Seems to work ... is it normal to have the "unknown" values below when
plugged in?

Some DELL battery issues in recent kernel are solved by
patch filed at http://bugzilla.kernel.org/show_bug.cgi?id=1766 .

Is it worthy to have it a try?
