Sorry for long subject, but what to do when gnome power manager shows wrong battery capacity?
I have two laptops for who I see that battery capacity is stated as 88.8Wh but it is not! So when gnome starts I get an error message saying I have a faulty battery. What do I need to do? Submit a bug? To what component? Send an email? To whom?
Thank you, Valent.

Thank you, Valent.
how old are the batteries?
If they're more than say, a year old, it's probably true. battery charge life declines. Get the info on your battery by clicking on the gnome-power-manager icon and you can find out the info on your battery.

One laptop is brand new and other is 2 years old.
On both laptops there are 6-cell batteries - my googling showed me that capacity should be around 60Wh for a 6-cell battery.
On both laptops gnome-power-manager (GPM) shows that capacity should be 88.8Wh (which I think is wrong).
On new laptop actual capacity that GPM shows is 60Wh and on the old laptop is 44Wh (it droped from 60 to 44 in 2 years).

Well, if my physics teacher was right then no application shows wrong values. 6000mAh and 148000mV compute to 88.8Wh. So either the battery gives wrong values via acpi or the kernel reads them wrong (which is very unlikely because 6000mAh seem to be a too normal value for a read error)

Upps :) my bad... I mixed my units. I saw mAh but I read it mWh :(

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.

It will be case where the "smart battery" (deliberate quotes) is actually very dumb. For most of the DSDT's I've seen most of these numbers are hardcoded, and not queried from the battery.
I've even sent the Lenovo BIOS guys a DSDT patch to query the battery instead of a best guess, but it was ignored. This is why the new g-p-m code self-profiles, and corrects the values from ACPI.
Richard.
I also checked my old HP nx9030 and the battery label says this:
11.1V and 4400mAh (which is 48.84Wh) but GPM says that design charge is 88.8Wh!
This is obviously not correct - I can provide the photo from the battery label if you don't trust me.
here is other info from HP nx9030 laptop battery:
# cat /proc/acpi/battery/BAT0/info present: yes design capacity: 6000 mAh last full capacity: 2528 mAh battery technology: rechargeable design voltage: 14800 mV design capacity warning: 250 mAh design capacity low: 150 mAh capacity granularity 1: 10 mAh capacity granularity 2: 25 mAh model number: JM-6 serial number: 4063 battery type: LION OEM info: Hewlett-Packard

I'm back on my original question.
On HP Pavilion dv6426us GPM shows: Current Charge: 50.5 Wh Designed charge: 88.8 Wh
and /proc show this:
# cat /proc/acpi/battery/BAT0/info present: yes design capacity: 6000 mAh last full capacity: 4032 mAh battery technology: rechargeable design voltage: 14800 mV design capacity warning: 207 mAh design capacity low: 125 mAh capacity granularity 1: 10 mAh capacity granularity 2: 25 mAh model number: Primary serial number: battery type: LION OEM info: Hewlett-Packard
But I pulled the battery out and on the back of the battery on the label it says: 10.8V and 47Wh
that is 4350 mAh not 6000 mAh as /proc info says... and design voltage is also wrong.

Either the label is wrong, or the "smart" controller chip in the battery is wrong. If the battery is giving us wrong information, then it's not our fault.

I'm a but suspicious because I see same maximum capacity for different batteries and different laptops...
Can you correct battery info if users like me give you feedback and correct info?

I wasn't implying that fedora/gpm or any other component is wrong or that you made some mistake I am only asking how can I fix it. If I know exactly what are my battery specs and their "smart" electronics reports some bogus data I would like to have some way of correcting the wrong info.
