Re: what to do when gnome power manager shows wrong battery capacity?



I found out why I got mixed up... I'm not an idiot after all :)

I have fedora core 6 system that I use for work - and on FC6 GPM shows
only W (not Wh or Ah) and it should be Wh as the number are the same
as from /proc/acpi/battery/BAT0/info

Here it is:

Laptop IBM Lenovo Thinkpad R52

cat /proc/acpi/battery/BAT0/info
present:                 yes
design capacity:         47520 mWh
last full capacity:      47690 mWh
battery technology:      rechargeable
design voltage:          10800 mV
design capacity warning: 2384 mWh
design capacity low:     200 mWh
capacity granularity 1:  1 mWh
capacity granularity 2:  1 mWh
model number:            IBM-92P1071
serial number:            7721
battery type:            LION
OEM info:                SONY



Gnome Power Manager:
Serial Number:     7721
Model:             IBM-92P1071
Capacity:          100%
Current charge:    47.7 W
Last full charge:  47.7 W
Design charge:     47.5 W

So in 1.5 years this old battery even got better :)

Why in Gnome Power Manager 2.16.3 the capacity is in W and not in Wh?

Thank you,
Valent.
