[Lenovo x230, Thinkpad L530, T530, T430s] Battery button doesn't function

[Greg Vallande]

When pressing Fn+Battery key - the system responds as if you hit CTRL-L and locked the desktop. There are a few that are currently suffering from this problem.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.6 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. Please only remove that one tag and leave the other tags. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I've got an X230 too, I've read the manual and cannot find the Fn+Battery key combo. Which keys are you referring to?

[Colin Ian King (colin-king)]

@Jeff, can you answer my question in comment #3. Thanks.

[Jeff Marcom (jeffmarcom)]

@Colin,

I only added the L530 to this bug. However, I believe the key combo fn+f3 is standard for all of our lenovo's in the lab.

[Colin Ian King (colin-king)]

I'm confused, Fn-F3 on my x230 is screen lock - it even has the lock icon in the button.

[Jeff Marcom (jeffmarcom)]

This may be due to a difference in an engineering build vs retail on the laptops. I'll try and confirm.

[Colin Ian King (colin-king)]

..which of course may explain why your version with the battery button is issuing an screen lock code, which is what I have on my retail (UK) version.

[Colin Ian King (colin-king)]

@Jeff, any update on this?

[Colin Ian King (colin-king)]

@Jeff, it's nice that you can update the summary, but can you get back to my original question #3. Thanks!

[Colin Ian King (colin-king)]

@Jeff, I'm still waiting for your answer to my question in comment #3 - any followup?

[Colin Ian King (colin-king)]

Without wanting to sound like I'm whining, I'm waiting for some follup up on this issue. Everyone seems to like to update the bug with summary changes and shiney tags but no-one is addressing the fundamental questions I'm asking. I'd like to get this one resolved. :-)

[Jeff Marcom (jeffmarcom)]

@Colin,

see comment #5 to answer your question in #3.

Again, all of our lenovos have the key combo fn+f3 as the battery key.

If this helps at all (I don't know how relevant this is to you), that key combo for the lenovo w530 works as expected on precise 12.04.1.

Please let me know what you'd like me to try next. Sorry for the delayed response.

[Jeff Marcom (jeffmarcom)]

Okay, so a little more info,

I installed 12.04.1 on an x230 (which by the way the fn+f3 combo is the battery NOT the lock) and it works fine.

Loading 12.04 to see if I can reproduce. I was not the originator of the bug on the x230.

[Jeff Marcom (jeffmarcom)]

Works as expected on the x230 with 12.04 (kernel rev 3.2.0.23 #36)

[Jeff Marcom (jeffmarcom)]

Okay, so.

This original defect was opened on precise. However the kernel listed was a 3.5 rev.

I tested the following kernels and see that now the battery key does nothing no even logged with udevadm monitor:

quantal: 3.5.0.0300
quantal: 3.5.0.17
quantal: 3.5.0.22
raring: 3.8.0-1

This seems to be broken upstream.

[Jeff Marcom (jeffmarcom)]

Let me know if you require information. Please feel free to contact me directly.

[Jeff Marcom (jeffmarcom)]

Seems it's a package issue. Even when it's successful it doesn't invoke a change through udevadm. When I did a full installation of raring instead of just updating the kernel it works flawlessly on the x230 and the l530.

Seems this bug is invalid and just requires an update to gnome-power-statics.

[Colin Ian King (colin-king)]

Thanks for the feedback Jeff. Your findings do make a lot more sense.
