    acer-wmi: unable to detect available WMID devices

    I'm running UNR 9.04 on an Acer Aspire One D150-1920. On my most recent bootup, my usplash screen failed to load, instead being replaced with terminal script. it indicated that WMID devices were not detected.

    I pulled my dmesg.log and confirmed it:

    [ 17.880771] acer-wmi: Acer Laptop ACPI-WMI Extras
    [ 17.956594] synaptics was reset on resume, see synaptics_resume_reset if you have trouble on resume
    [ 18.009321] acer-wmi: Unable to detect available WMID devices
    Any ideas on a fix/workaround, so I get my usplash back?

    Yeah, I'm having nearly the same problem.
    Only I'm running the desktop edition of 9.10 on my acer
    aspire one.
    Any suggestions?

    The fix was this: you need to run this at the command line:

    fsck

    It will run a disk check just like in Windows, then repair the error.

    It worked for us - problem sorted immediately!

    Take care!

    This is a dangerous thing to do if not done correctly, read this wiki.
    http://en.wikipedia.org/wiki/Fsck

    and this paragraph.

    A system administrator can also run fsck manually if there is believed to be a problem with the file system. Because running fsck to repair a file system which is mounted for read/write operations can potentially cause severe data corruption/loss, the file system is normally checked while unmounted, mounted read-only, or with the system in a special maintenance mode that limits the risk of such damage.

    I'm having this problem too on an Aspire 5515. I doubt a fsck will fix it.
    This is not a signature.

    a forced fsck does not fix this. It appears that the battery is being detected improperly, as I see the model number change. I wonder if there's a way to force the model number and Energy (Design) attributes to be at a certain value regardless of what's detected by the power manager or the battery manager? That should solve all issues and be a decent workaround until a permanent fix is available.

    sudo apt-get update
    sudo apt-get install -f
    sudo dpkg --configure -a

    will force a fsck on next boot:

    sudo shutdown -F -r now
