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

 

Folks,

After a long period of suffering, I found that this issue was caused by
a combination of hardware and software problems. Apparently my laptop
had power related problems, which were resolved by a motherboard
replacement. This fixed the main problem, but I was still having
problems having ubuntu recognizing the lid actions (open/close). After
some troubleshooting, I found that the crashplan daemon running in the
background was causing it.

Here's a one-liner for checking the lid actions in case you have a
similar problem:

while true; do cat /proc/acpi/button/lid/LID0/state; sleep 1; done

If you don't see "close" when you close the lid, then you might like to
check for running processes, starting with crashplan.

I tried to mark this case as solved, but I can only see "fix
committed/released" options. How can we properly close this case?

Thank you all from Canonical and Ubuntu community for your valuable help
and feedback!

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!
