Here are the results:

Tested Mainline 3.12 (trusty): 3.12.031200-generic for i386

No change in the battery status issue - I did recognize a battery but
status (plugged/unplug and % charge) didn't change when I issued the
acpi command.

Further info: When I installed the kenel via terminal, part of the
output gave errors (note the "version string" error has been around a
long time, so it is not specific to that kernel):

Consult /var/lib/dkms/nvidia-304/304.88/build/make.log for more information.

Also when the computer booted, I got the "Could not apply stored
configuation for monitors" error (ended up with some bigger icons but
everything else seemed to work fine).

As noted before, my Ubuntu splash screen blinks some quick error in red
(too quick to be able to read it) before the login screen appears.  The
Ubuntu splash is also just a text of Ubuntu 12.04 with small dots below
it instead of the larger "Ubuntu" with the icon and large dots (has been
like this for a while with the newer 3.5.x kernels - the older, non-
mainline kernels I tested in #41 booted with the large text and icon).
Doubt it's related but may be some more info.

Let me know if there is anything else you want to test.  My impression
is that this issue may be some quirk with my 4yr old laptop and likely
affects very few, if any other, people.  If this becomes something that
is not worth your time to continue to work on, I do understand.

Title:
  No low battery notifications and no updated battery status (ACPI
  Errors

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  1. I do not get warnings when the battery is low (laptop promptly
  shuts down).

  2. Battery power level is not updated. using acpi the battery power
  shows the same level present when the laptop booted - it never updates
  (if booted at 98% it will show 98% until rebooted).

  3. Battery status (on power vs on battery) functions sporadically.
  Often after an update the status will work for several boots but then
  stops working (icon only shows status when booted - ie, if cord
  plugged in, the status will not change to "on battery" if unplugged;
  it still shows that the laptop is plugged in.

  4. In power settings, "Show battery status in the menu bar" is blank.
  I can select options from the dropdown menu but they are not retained
  (when I close and reopen the settings it is blank again).

  5. Went to gconf-editor apps > gnome-power-manager and noticed that
  there is no "notify" folder/keys.

  6. Noticed that there is no gnome-power-manager.desktop in
  /etc/xdg/autostart/ (wanted to add it to autostart to see if that
  would help).  I have tried using synaptic to reinstall gnome-power-
  manager but it didn't help.

  Currently, my status (icon changes to battery/plugged in) and acpi output is:
  Battery 0: Unknown, 98% (plugged in)
  Battery 0: Discharging, 72%, 00:59:42 remaining (on battery)

  I have also added my dmesg outputs for on battery and on power
  (attached).  The laptop is an MSI-171F.  I have tried blacklisting
  msi-wmi in modprobe.d/blacklist.conf (didn't help).  Also noticed that
  etc/acpi has sevearl asus*.sh files (touchpad, keyboard backlight) in
  the folder (could that be the problem)

  Note: I currently have Jupiter enabled but have disabled/uninstalled
  it

  before and it didn't seem to affect the behavior.
