Battery recognition

Hey folks,

i am having problems with my new laptop an lenovo ideapad u430p.
Actually it's working very well, except the battery isn't correctly recognized on about every 3rd boot.
I have a xfce setup and xfce4-power-manager applet running, and when it is not working it shows that the laptop is on powerline and full, even when it is on battery.
Plugging the power in or off does not change anything.

i first thougt, some modules are not loaded. but a diff on a lsmod output of a working and a not working boot gives me no difference

i can see differences in /sys filesystem like:
/sys/devices/pci0000\:00/

but i have no clue where or how i can track that problem.

can sombody give me a hint? or does someone have similar problems?
Thanks in advanced

Re: Battery recognition

I saw this the first time you posted, but it seemed quite odd - I have no related experience, but maybe you can gather more data:

First, you say you see differences in the /sys/ entries (I find the symlinks easier to make sense of under /sys/class/power_supply myself).  But what are these differences?  Do you mean the entries are different when it 'works' and does not work as expected?

Have you tried other power managers, or other OSs (even a live cd/usb)?  Do they work consistently, or show the same issue?

Re: Battery recognition

Hey Trilby, thanks for your reply.

i haven't tried any other live distribution. haven't thought about this possibility, i will definitely give it a try.

The differnce in /sys filesystem is this:
working:

ll /sys/class/power_supply
insgesamt 0
lrwxrwxrwx 1 root root 0  5. Feb 21:52 ACAD -> ../../devices/LNXSYSTM:00/device:00/ACPI0003:00/power_supply/ACAD
lrwxrwxrwx 1 root root 0  5. Feb 21:52 BAT1 -> ../../devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT1

not working:

ll /sys/class/power_supply
insgesamt 0
lrwxrwxrwx 1 root root 0  5. Feb 22:03 ACAD -> ../../devices/LNXSYSTM:00/device:00/ACPI0003:00/power_supply/ACAD

One thing i recognized after a dozen of reboots, when it does not work it also does not shutdown correctly.
it gives me something like this (no logs found):

...systemd-udev[221] not responding killing it.
...systemd-udev[224] not responding killing it.
...systemd-udev[232] not responding killing it.

then a few lines, i can't remember.
keeps hanging, no shutdown just by pressing power_button 4 secs.

last line of journalctl when it does not work:

Feb 05 22:03:14 sepp-lappi systemd[1]: Shutting down.
Feb 05 22:03:14 sepp-lappi systemd[1]: Hardware watchdog 'iTCO_wdt', version 0

2 more things i found in journalctl:

Re: Battery recognition

Thanks for the info - I'm not sure where to look next, but other power management tools will almost certainly have the same proble (i.e. it's not an issue xfce's power manager).  As far as I know - which really isn't far in this case - the /sys/device directory tree is a virtual space that represents hardware the kernel is detecting.  So another distro/OS and/or another kernel version would be the next step if I was trouble-shooting this.  Have you had different kernel version since you've been running arch on this machine?  If so, was the issue present in all of them?

Re: Battery recognition

I am not sure if there were any kernel updates, the installation is quite new. so maybe one or two. I will look it up in the evening when i am home.
i will also give an live usb stick a try and post my findings.
Thx for your help so far.

Re: Battery recognition

Same problem here, this time with a Ideapad U330P (the same Haswell chipset).

Atfer some reboots (3 or 4, I'm not sure), the battery is not detected by the system (Gnome 3 in this case). Rebooting, the battery come back.
Happens with openSUSE, 13.1, too. But I think that not happens with Fedora 20, at least in my test. With this distro, battery is always detected.
