Description of problem:
Very often, after I disconnect the AC from my Lenovo X201, the battery icon in 
the panel becomes immediately red and says 6.2% charge left. The remaining 
time, however is correct (2h40 left).

The value slowly goes down as the battery discharges. So there seems to
be an incorrect multiplication factor applied to the number.


The command line tool acpi reports the correct percentage:

 bernie@giskard:~$ acpi
 Battery 0: Discharging, 59%, 02:46:56 remaining


Version-Release number of selected component (if applicable):
gnome-power-manager-2.32.0-3.fc14.x86_64

How reproducible:
very often (always? not sure)

Steps to Reproduce:
1.disconnect charger
2.look at battery icon

Actual results:
5.7%

Expected results:
56%

Same behavior here. My battery estimate is always off by a decimal place.
it'll say 9.3% in the applet but the real battery life is 93%

The time is right - but the battery icon is wrong and the percentage is
wrong.

Can you test the kernel from

I've still got this problem with Fedora 16 x64 (EFI boot) on a macbook
pro 8,1. Sometimes the "energy when full" value in upower becomes much
too large causing the battery to report a low percent.  Time is still
reasonable.  Killing upowerd seems to fix the problem.

Sorry for the double post.  Can this bug be reopened?  Also I think the
effected component should be upower not the kernel.

Dan,

Please open a separate bug. You have similar symptoms, but if it was the
same problem it'd already be fixed.

Title:
  ThinkPad battery applet shows incorrect information

Status in devicekit-power package in Ubuntu:
  Invalid
Status in upower package in Ubuntu:
  Confirmed
Status in upower package in Fedora:
  Fix Released

Bug description:
  Binary package hint: devicekit-power

  The GNOME applet shows the actual capacity divided by ten (8.8% when
  the battery is at 88%). I've attached output from  /usr/share/gnome-
  power-manager/gnome-power-bugreport. The time to depletion and time to
  full charge do not show at all.

  I've verified using tp-smapi-dkms that the applet shows incorrect
  data.

  This laptop runs Ubuntu 10.04.1 64-bit.

  == Correct data excerpt ==

  Battery Information:
    battery.charge_level.current = 8406  (0x20d6)  (int)
    battery.charge_level.design = 9324  (0x246c)  (int)
    battery.charge_level.last_full = 9527  (0x2537)  (int)
