    I've noticed this too on the odd occasion. Sometimes from returning from suspend too. I haven't found (or looked) for a fix yet.

    Has anyone got the UMTS (3G) module working in Ubuntu?

    By the way, is the Intel version of the Lenovo x121e with Intel HD 3000 GPU better supported and more stable (through open source drivers) than the version with the AMD Fusion E-450 APU? Several reports mention that suspend/hibernate doesn't work that well with the AMD versions.

    Thanks!

    connect404 you're my hero

    On my brand new X121e with a gnome 3 ubuntu 11.10, I only got 3 to 4 hours of battery, I was even concerned being flogged a 4 cells battery instead of the 6 cells I ordered, but no.
    When I first ran Powerstat I got a 15 W average.
    Now after a simple "aspm=force" I get a 6.13 Watts on average with standard Deviation 0.05
    And I haven't even configured TLP yet

    Warm greetings from southern France

    I have the same issue. It happens roughly once a week. There is a bug record concerning this here

    Re: Lenovo x121e i3 Linux Hardware Compatability

    With Ubuntu 12.04 are the above power issues automatically fixed? Or do I need to do some of the above fixes, and if so which ones?

    And does anyone have any experience with the fingerprint reader?

    I'm very new to Ubuntu so just learning my way around...

    Thanks

    Concerning RC6 it should be enabled by default when the 3.4 kernel will be released to ubuntu. The actual one is 3.2.0-25-generic then you have to enable RC6 manually in grub (see the firsts post of this thread for details).

    See Linux 3.4 will use Intel's power saving RC6 GPU technology - The H Open: News and Features

    or try this search rc6 power saving linux kernel - Google

    I haven't got fingerprint reader so...

    Here is someone writing something intelligible about this. It does however appear beyond my ability to fix. i thought that someone here might know what to do with it.

    Thanks, so from what I can see 12.04 has RC6 enabled by default. I've done APSM=force and installed TLP, went from 8.54 W to 6.62W. Havent found anything for the fingerprint reader though.....

    Hi getting some problems with 13.04 on my x131e. Random system freeze leaves me unable to input or output anything.

    Is anyone else having this problem?
