    For those of you who have a Sentelic touchpad on their zenbook, you may be interested to look at this thread:

    Re: Ubuntu and the asus zenbook (UX31)

    what kind of battery time you guys/girls get with zenbook u31?
    after installin 12.10 kubuntu with mainline 3.6.3 kernel it wont last about 4 hours.
    powertop shows:
    The battery reports a discharge rate of 9.41 W

    I havent done any Power Saving Optimizations.
    just grub settings:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force drm.vblankoffdelay=1 i915.semaphores=1"

    Re: Ubuntu and the asus zenbook (UX31)

    Hey,

    I'm running my system with Ubuntu 12.10 and I'm getting nearly 6h of battery live (displayed) (~ 4.9W - 5.4W with Wifi and brightness level 3).

    I've got kernel parameters, ALPM enabled and missing PowerTop tweaks activated AND I deactivated the SD-Card driver. This driver looks every (i think) 50ms for a new card --> drains energy!

    I will post my configs later that day (I'm on another pc).
    But with my config i'm getting RW-Errors on my /home directory (but only with kernels above 3.4 O.o)...would be interesting if anyone else is also getting this (with my config)!

    I get about 5 hours. I use "laptop-mode" with (almost?) no customization. I think the only thing I did was to blacklist the USB-3 port, which was getting shut-off permanently when the power cord was pulled. I can dig up my details if you like. For my money, it's much easier than tweaking a power script.

    I'm working with 3.2.23 . 3.5.19 is also installed, but with this kernel I'm getting the Read-Only Filesystem Error

The automatic check log I got claimed something about "battery error" and "no power". I have it 5 days now, no shutdowns whatsoever. I'll report here if the issue appears again.

    For the record, I am running UX21E with ELANTECH touchpad, I always update my BIOS to latest (2.13 at the time of writing), I am also using the power tweaks from the wiki.
    Same here with my UX31E.

    Unexepected shutdowns. First time ASUS has changed the motherboard and updated the BIOS to 214 version. Ran 3 weeks with no problem and now I'm here again.

    I've just opened a new ticket to Asus Support.

    Thanks, I will test your scripts and ALPM and 3.2.23 kernel.
    with 3.6.3 in suspend my asus eated 5% battery in two hours, so not so good.
    maybe kde is also battery eater.
    Code:
                 17.3 ms/s      51.0        Process        /usr/bin/plasma-desktop
                 16.3 ms/s      61.5        Process        /usr/bin/X :0 -core -auth /var/run/lightdm/root/:0  -nolisten tcp vt7 -novtswitch -background none
    but only possible to me is use xubuntu
    unity no thanks, and gnome shell isnt yet ready imho..

    Re: Ubuntu and the asus zenbook (UX31)

    overnight about 20hours in suspend and 40%battery drain.(with 3.2.23 kernel and powersave script and sata alpm enabled)
    I think I will change back to 12.04 kubuntu..

    Re: Ubuntu and the asus zenbook (UX31)

    The overnight drain wasn't better on 12.04 (at least for me)...I think it changed when I updatet the bios from 211 to 212 (3% to 35% in 24h)...I don't know what they changed in the bios because they do not release any changelogs

    I got only one solution: use hybrid suspend, hibernate or shut down. Just avoid suspend!
