           Summary: Battery charge level is not displayed correctly
           Product: ACPI
           Version: 2.5
     KernelVersion: 2.6.22-gentoo.r4 (from a 2.6.22-3)
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Power-Battery
        AssignedTo: acpi_power-battery at kernel-bugs.osdl.org
        ReportedBy: StormByte at gmail.com


Most recent kernel where this bug did not occur: NA
Distribution: Gentoo
Hardware Environment: Samsung R70 Laptop
Software Environment:
Problem Description: The battery level is not displayed correctly though any
software supporting acpi. I tested with /proc/acpi/battery/bat1/{state &&
info}.
This is /proc/acpi/battery/BAT1/state 
present:                 yes
capacity state:          ok
charging state:          charged
present rate:            0 mA
remaining capacity:      5586 mAh
present voltage:         12477 mV

And this is  /proc/acpi/battery/BAT1/info 
present:                 yes
design capacity:         5200 mAh
last full capacity:      5700 mAh
battery technology:      rechargeable
design voltage:          11100 mV
design capacity warning: 0 mAh
design capacity low:     171 mAh
capacity granularity 1:  1 mAh
capacity granularity 2:  1 mAh
model number:            
serial number:           
battery type:            LION
OEM info:                SAMSUNG Electronics

The problem is: I have it most the time connected to the charger, lecture
sometimes is that charge is 5700, and thus, 100%, and sometimes it gets stuck
at 97% (like now: 5586).

Other odd thing is that battery is designed to have a capacity of 5200 mAh by
design, but last full capacity (wich can be reached sometimes) is 5700.. This
may confuse ACPI related programs so I dunno what to do. I don't think anyway
that this is related to theese other programs, as this behaviour is the same
for all programs I tested, so it must be something of ACPI controller.

Should you need any more information, just tell me and I'll post it.
