Battery not detected under Power Statistics, Battery Indicator not showing in menu bar, and Battery Status setting under Power not sticking

[Patrick Akridge]

When I start Ubuntu, when I login to Unity OR Gnome (whether it being Classic or regular Gnome), the battery indicator won't be showing in the status bar..

Also, when the battery indicator isn't showing, the battery isn't detected in Power Statistics..

When I open Gnome-Control-Center, the Show Battery Status in Menu Bar setting under Power shows a blank option, and if you choose an option, it doesn't stick..

When I suspend and wake up the system, then it shows up..

I have tried other things to get it show up like Alt > F2 and "r" as the command

and Rebooting the system, and other things...

This happens EVERY time I reboot, and is not a one time thing so that is how I know it is a bug..

A quick Google search shows that it affects other users, not just me, so that is why I have changed the status of the bug to confirmed..

What I expected to happen..

I expected the system to display the status of the battery without having to put the system to "sleep" and wake the system..

What happened?

Every time I boot up the system after it has been completely powered off, the system doesn't display the battery indicator AND Power Statistics doesn't recognize my laptop battery that is in a fully functional condition (the battery isn't but 6 months old)..

What did I do for this to happen?

I did nothing but boot my system up..

Patrick,

Please do not confirm your bugs unless instructed by a triager. I will leave it as confirmed, tho, as this also effects me and I experience identical symptoms. Also, I'm not quite sure about your package choice. It seems that one component of Ubuntu detects our laptops as desktops, and effects Unity, Gnome-Control-Centre, rather than each individual program having a seperate bug.

Muchas Gracias!

Thanks...

I was asked to add the three rules of thumb, so I did..

[Patrick Akridge (everthingappleshow)]

I am sorry about the multi- bug report... I entered the packages that I needed to file the bug under, and it randomly created a SEPARATE bug for EACH package.

Patrick,

That's OK! It just seems like the bug is more Ubuntu itself recognizing it as a laptop- and just not telling each of those programs. I definitely appreciate you having a great description. :) I'd like to know what happens with this bug, as for the people that have it, it's a huge bumber.

Muchas Gracias!
Evan Peck :~)

Why was Unity removed?? It affects Unity in some cases...

Can we add that back?

Patrick,

Probably not. Omer knows when it's a Unity bug of not (he's a Unity community hacker). You said it effects both Unity and GNOME Shell, so that means it's not a bug SPECIFIC to Unity. As I said in #5, it might be a hardware detection problem, so run:

uname -a > uname-a.log

cat /proc/version_signature > proc_version_signature.log

sudo lspci -vvnn > lspci-vvnn.log (those are 2 v's not a w)

dmesg > dmesg.log

and attacht the 4 files it outputs (uname-a.log, proc_version_signature.log, lspci-vvnn.log, and dmesg.log).
Muchas Gracias!

I'm having the same problem. The funny thing is that "acpi -b" tells me that the battery is present and detected, but I can't find it in /proc/acpi/battery.

[Pedro Nariyoshi (pedro-nariyoshi)]

I'm adding acpi -b just in case. I'm wondering if this is a Kernel issue rather than a gnome issue. Or maybe /proc/acpi/battery was relocated somewhere else and gnome (and I) just don't know where.
