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

 

Hi! Were any of the information useful? Anything else that I can
provide?

I would really appreciate any suggestions for troubleshooting since this
problem is significantly affecting the usability of Ubuntu. The fact
that the development live distro also has this problem indicates a
hardware compatibility issue with the existing/future Ubuntu releases.
If this is the case, are there any packages that I can downgrade to at
least get the functionality back until this bug is fixed?

Also, in case it helps, the "suspend" function does work, but closing
the lid does not trigger it.

Thanks again!

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

Status in “linux” package in Ubuntu:
  Confirmed

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!
