Subject: 3.9-rc3+: reports battery as 0 mWh capacity on thinkpad x60

Hi!

[email protected]:~$ cat /proc/acpi/battery/BAT0/info
present: yes
design capacity: 0 mWh
last full capacity: 0 mWh
battery technology: rechargeable
design voltage: 14400 mV

This worked before... at least it works in 2.6 kernel used by debian.

This works for me in 3.9-rc3. May I see your .config?

Well, if this works, then maybe the Kconfig help text should be updated:

config ACPI_PROCFS_POWER
bool "Deprecated power /proc/acpi directories"
depends on PROC_FS
help
For backwards compatibility, this option allows
deprecated power /proc/acpi/ directories to exist, even when
they have been replaced by functions in /sys.
The deprecated directories (and their replacements) include:
/proc/acpi/battery/* (/sys/class/power_supply/*)
/proc/acpi/ac_adapter/* (sys/class/power_supply/*)
This option has no effect on /proc/acpi/ directories
and functions, which do not yet exist in /sys
This option, together with the proc directories, will be
deleted in 2.6.39.


Time to call the bluff now :)

This should probably be "default y", BTW.

But problem is not in /proc, /sys has zeros, too.

Can you narrow the time frame when it stopped working a bit?

Well, 2.6.32 from debian works ok, and self-compiled 3.1+ kernel also
seems to work ok.

I'm not sure if 3.7+ kernels worked, actually... I'd have to do some
compiling to check.

Hi Martin:
Thanks to report the bug.
Both charge_full_design and energy_full_design
indicate the battery Design Capacity.
Their difference is unit. charge_full_design uses "mAh".
energy_full_design uses "mWh". The
same for charge_full and energy_full.
So from this output, it still works on the v3.7+. Could
you continue narrow
the time frame?
Which version you found the issue? could you provide the
output of dmesg
on it and acpidump? They will give us more clues since acpi battery
driver just exposes
data from Bios. Thanks in advance.

Hi Lan,
this is actually a bug of Pavel, he had the problem. I just wanted to show
him what works on 3.7.10 in my case (yes, different files are on my system).
If you feel the *missing* files are a problem, I can try some newer kernels
on my computer (Dell Vostro 3550), sure. I am attaching the files anyway
but I think 300kB won't make it into the email lists.

Hi Martin:
Thanks for reminder.

Hi Pavel:
Could you provide following info and apply a acpi battery
bug on the https://bugzilla.kernel.org? This can help others
to trace the bug.

Ok, I'm not sure when it stopped working, but it works again in
3.9.0-rc8+. Good :-).

(And sorry for slow response).

In the meantime, I got chromium-browser disappearing on me, all at
once, before it started opening initial tabs. This is first time I
seen that, with dmesg saying:

chromium-browse[3728]: segfault at 95968e80 ip b666875e sp af5e9a20
error 4 in chromium-browser[b5e0d000+1960000]

. I hope it is just a coincidence, because otherwise 3.9 looks
usable...

Thanks,
Pavel
