Subject: Battery Sometimes Not Detected
Date: Wed, 26 Oct 2011 18:05:33 -0400 [thread overview]
Message-ID: <4499333.9RBPNNDCzX@athena> (raw)
I wanted to submit this bug to the Kernel Bugzilla, but it appears to be
down.
Anyway, I'm on kernel 3.0, using 64-bit Arch Linux on a Dell Latitude
E6410. Every now and then, the battery shows up as though it's not
connected, even while running on it. This is seemingly random, and if it
happens, I just reboot my laptop and it will see the battery fine most of
the time. I want to say about one in ten boots it doesn't see the
battery on average. I filed this first against KDE, but then the problem
happened in XCE so it's not a KDE issue. Then, I filed it against upower
but they told me this is a kernel bug.
An interesting point to note is that while this problem happens whether
I am using my docking station or not, if I undock my laptop while the
laptop doesn't see the battery, all of a sudden the battery is
recognized.
Running "ls /sys/class/power_supply/" while suffering from this bug gives
me:
AC
