F18, acpi problem on an Asus Ultrabook

Hi

I own an Asus Zenbook UX32. F18 64Bit is running great on this
machine. On thing in strange: The battery capacity seems to be less
than running Windows 8 on that Ultrabook.

I investigated this behaviour. I think, this issue is related to ACPI,
because there are no CPU or fan data in /proc/acpi.

[ukiewel@asus ~]$ ll /proc/acpi
total 0
dr-xr-xr-x 3 root root 0 Feb 17 22:23 button
- -rw-r--r-- 1 root root 0 Feb 17 22:23 wakeup

Using acpitools, my Asus Ultrabook is not recognised as Asus:

[ukiewel@asus ~]$ acpitool -A
Sorry, but no Asus ACPI extensions were found on this system.

The other informations provided by acpi tool are also wrong:

[ukiewel@asus ~]$ acpitool
Battery is not present, bailing out.
AC adapter : <info not available>
Thermal info : <not available>

While typing this mail, the Ultrabook runs on battery.


Here some details from dmesg:

Any idea how to fix it?

Thanks

Hi Uwe,

It sounds like a bug. I'm not really sure how you'd fix it. If you
file a bug, the maintainer may have some insights or workarounds.
