[kde-freebsd] HP Elitebook 8460p and problem with KDE 4.10, 5 battery monitor

[Craig Rodrigues]

Hi,

I am running an HP Elitebook 8460p laptop:
http://h10010.www1.hp.com/wwpc/pscmisc/vac/us/en/sm/notebooks/8460p.html

I am running a fairly updated FreeBSD-10 from sources:

FreeBSD 10.0-BETA2 #2 r257540: Fri Nov  1 21:41:42 PDT 2013

I am running kde 4.10.5 installed with the pkg utility from pkg.freebsd.org:

kde-baseapps-4.10.5_1          Basic applications for KDE


The full KDE desktop starts up and works great.  I have no major problems
with it.  Thanks!

However, if I reboot and unplug my laptop, I have one annoying problem.

The KDE Battery monitor thinks that I have no battery life left, and
suspends my laptop in 30 seconds.

>From the OS level, everything looks fine.  Here is the output
of:

 sysctl hw.acpi.battery

I'm not sure, but I think that the KDE battery monitor
is getting confused that the hardware supports having two batteries,
but I only have one battery installed.

I see that Alberto Villa submitted this patch to KDE:

https://git.reviewboard.kde.org/r/110941/

I think this patch is related to my problem and may solve it.  Has this
patch
been pushed upstream to KDE, or do we have it in the FreeBSD port?

Thanks.
