[Bug 1210361] Re: [Samsung NP540U3C-A01UB] Incorrect battery/power status and missing /proc/acpi/battery

 

MeMo, 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-rc5

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.

Title:
  [Samsung NP540U3C-A01UB] Incorrect battery/power status and missing
  /proc/acpi/battery

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hi after the last Ubuntu upgrade, I am having these power related
  problems:

  1) the initial battery/power indicator does not change when the laptop
  is plugged/unplugged. If the laptop was on battery, the indicator
  continues to show it after I plug it in, and vice versa.

  2) Sleep never works when the lid is closed, however it can be invoked
  using  "/etc/acpi/sleep.sh" or selecting suspend from the menu.

  3) /proc/acpi/battery got disappeared

  I am attaching the following:

  - version.log
  - dmesg | grep ACPI
  - dmidecode
  - lshw
  - lscpu -vnvn
  - /proc/acpi when plugged
  - /proc/acpi when on battery
  - uname -a

  Ubuntu is my primary OS so I will appreciate any suggestions for resolving this issue. Thanks in advance!
