gnome-power-manager does not update often enough, only updates every 25% of battery charge

[singularity]

Binary package hint: gnome-power-manager

As the summary says. It should definitely update more, at _least_ once every 5%. I understand polling is to be kept to a minimum to avoid unnecessary CPU usage but really, it'd be nice if when I look at my battery stats, they don't go from 25% on first look, then to 0% on the next...

This bug is in Edgy.

g-p-m lists tell me this is a HAL problem.

[singularity (singularity00)]

Okay, this is not a HAL issue:

paul@paul-laptop:~$ lshal -m

Start monitoring devicelist:
-------------------------------------------------
acpi_BAT1 property battery.reporting.rate = 1804 (0x70c)
acpi_BAT1 property battery.reporting.current = 4469 (0x1175)
acpi_BAT1 property battery.reporting.rate = 1948 (0x79c)
acpi_BAT1 property battery.reporting.current = 4452 (0x1164)
acpi_BAT1 property battery.reporting.rate = 1781 (0x6f5)
acpi_BAT1 property battery.reporting.current = 4436 (0x1154)
acpi_BAT1 property battery.reporting.rate = 1883 (0x75b)
acpi_BAT1 property battery.reporting.current = 4421 (0x1145)
acpi_BAT1 property battery.reporting.rate = 1786 (0x6fa)
acpi_BAT1 property battery.reporting.current = 4405 (0x1135)
acpi_BAT1 property battery.reporting.rate = 1785 (0x6f9)
acpi_BAT1 property battery.reporting.current = 4392 (0x1128)
acpi_BAT1 property battery.reporting.rate = 1769 (0x6e9)
acpi_BAT1 property battery.reporting.current = 4376 (0x1118)
acpi_BAT1 property battery.reporting.rate = 1847 (0x737)
acpi_BAT1 property battery.reporting.current = 4359 (0x1107)
acpi_BAT1 property battery.reporting.rate = 1785 (0x6f9)
acpi_BAT1 property battery.reporting.current = 4345 (0x10f9)
...

So clearly, HAL and acpi are working. This is a g-p-m problem.

Can the maintainer please comment?

[Paul Sladen (sladen)]

There is no polling involved, ACPI battery updates come in and g-p-m status is updated.

Are you talking about the battery icon only having a limited number of positions?

Can you do a screenshot showing what appears to be wrong for you? For example if hovering over g-p-m says '75%' but typing 'acpi' at the command line says '53%'.

[singularity (singularity00)]

Yes, but it isn't just the battery icon, its the information dialog too. I wasn't able to take a screenshot with the battery-icon popup, but here's the dialog box which is the same. Take a look.

Just to drive the point home....

[singularity (singularity00)]

Any ideas on what might be causing this?

Okay, this is a hal issue, thanks much to Richard Hughes. Can the Ubuntu HAL maintainer apply this patch?

[Alexander Hall (compuguy1088)]

I have also seen this on a Acer Aspire 3003LCi, but slightly different way. The battery, on AC, reports charge correctly. Though, from observation, via g-p-m and acpi, when on battery, the battery reports 100% charge when the actual charge is 50%. When it is under 50%, it reports 0%.

Problem still exists in feisty...

When will Ubuntu's HAL be updated with the aforementioned fix?
