[HP Folio 13-1020us Notebook PC] battery state incorrect on 12.10

[Alan Westhagen]

I have recently installed Ubuntu 12.10 64-bit desktop on an HP folio 13-2020us laptop. The battery status indicator in the top-of-screen panel always shows fully charged, even when the machine has been running disconnected for some time.

Status changed to 'Confirmed' because the bug affects multiple users.

I'm affected by this bug on a HP Folio 13-2000 on Debian Wheezy. Since package 'acpi' provides a small program that "displays information on ACPI devices" (see package description: http://packages.ubuntu.com/raring/acpi), I'm reassining this – as far as I know ACPI is handled by a kernel module.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.7 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I tested this with upstream kernel version 3.7.0 and the issue is still present; so maybe this is an upstream kernel bug. However, I'm not really sure this is a kernel bug at all – the output of 'acpi -a -b' seems to be correct… Alan, can you confirm this?

I don't know where UPower get's its information about battery and AC adaptor status.

[Stefan Nagy (stefan-nagy)]

At least in my case 'upower --dump' shows that the status of devices line_power_ACAD and battery_BAT1 isn't up to date. The time of the last update is nearly identical to uptime…

[Alan Westhagen (supportstuff)]

Yes, I am seeing the same thing. The output of 'acpi -a -b' looks
plausible. It's power widget in the panel that is clueless.

Since battery status seems to be detected correctly by the kernel and power management in GNOME (and Unity) is handled by gnome-settings-daemon [1], I'm reassigning this bug once again.

I guess this is a duplicate of #994745 – Alan, can you confirm that?

[Alan Westhagen (supportstuff)]

Yes, this is very likely the same bug. -- Alan

Thanks, I marked this bug as duplicate of bug #994745, which seems to be an upstream kernel bug. Looks like all the HP Folio 13 sub-models are affected…

Alan Westhagen, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
