Bug Description
Since hardy (tried alpha 1,2,4 and beta with clean installs) the battery reports inconsistent data, everything ok in gutsy
acpi -V
Battery 1: charging, 25%, 08:11:18 until charged
Thermal 1: ok, 42.0 degrees C
AC Adapter 1: on-line
08:11:18 hours until charged?! and 25% charged when it hasn't been unplugged for a week?
cat /proc/acpi/
alarm: unsupported
present: yes
design capacity: 2577 mAh
last full capacity: 12301 mAh
battery technology: rechargeable

The gnome-powermanager reports
Status: Charging
Percentage charge: 26%
Charge time: 10 hours 2 minutes
Capacity: 100%(excellent)
Current charge: 53.6 Wh
Last full charge; 205.8 Wh
Design charge; 43.1 Wh

And I know for sure that the battery is 80% okee... in both cases the design is lower than the last full capacity..

I have a similar issue (on an MSI S271 laptop) with hardy (both amd64 and i386).
$ cat /proc/acpi/ battery/ BAT1/info

This is with the power cable plugged in and the battery fully charged:
$ acpi -ba
Battery 1: charging, 0%, 05:20:00 until charged
AC Adapter 1: on-line
$ cat /proc/acpi/ battery/ BAT1/state
present: yes
capacity state: ok
charging state: charging
present rate: 2304 mA
remaining capacity: 14 mAh
present voltage: 13377 mV
With the mains unplugged :
$acpi -ba
Battery 1: charging, 100%, until charged
AC Adapter 1: off-line
$ cat /proc/acpi/ battery/ BAT1/state
present: yes
capacity state: ok
charging state: charging
present rate: 2555 mA
remaining capacity: 25358 mAh
present voltage: 1343 mV
In both cases, I sometimes get instead of the proper values: battery/ BAT1/state
$ cat /proc/acpi/
present: yes
capacity state: ok
charging state: charged
present rate: unknown
remaining capacity: unknown
present voltage: 10000 mV
