    Hello Webmaster, I noticed that https://roshanbook.wordpress.com/2011/10/01/solving-lenovo-g460-headphone-problem/ is ranking pretty low for some keywords, this may be due to the new Google Panda update, or it could be due to a variety of other factors. I’m sure you already know about On-page SEO, where Google cares highly about proper formatting of various H1/H2/H3 tags, having your main keyword appear in the beginning of your post and having your post end with the keyword, along with having keyword related alt tags and very relevant LSI. However, you do not seem to have the proper Keywords or relevant Keywords in your posts and in the website. Right now you need a tool or plugin that will allow you to check on Keyword insights, search trends and check for backlink analysis and to find out your Keyword competition.

    Hi Ueeu I am using Kubuntu in this laptop after solving all the sound problems

    From here: It is posted by myself🙂
    http://ubuntuforums.org/showthread.php?t=1394553&page=2

    “I fixed the sound problem by adding few lines to the /etc/rc.local file

    Now the mic-jack and the internal mic work even after reboot. Used the method used in the thread I posted earlier (hda-verb tool)

    My rc.local file looks like this now: If some one can tell if there’s a better way that adding this to rc.local file please tell me.

    #!/bin/sh -e
    #
    # rc.local
    #
    # This script is executed at the end of each multiuser runlevel.
    # Make sure that the script will “exit 0″ on success or any other
    # value on error.
    #
    # In order to enable or disable this script just change the execution
    # bits.
    #
    # By default this script does nothing.

    /usr/local/bin/hda-verb /dev/snd/hwC0D1 0x14 SET_CONNECT_SEL 0
    /usr/local/bin/hda-verb /dev/snd/hwC0D1 0x17 SET_CONNECT_SEL 0
    /usr/local/bin/hda-verb /dev/snd/hwC0D1 0x17 SET_PIN_WIDGET_CONTROL 3
    exit 0”

    you have to install the command hda-verb

    This is about downloading hda-verb from here
    http://ubuntuforums.org/showthread.php?t=1618138

    “Thanks for your hint, it’s working! I downloaded HDA Verb from kernel.org, compiled it and copied the executable to /usr/local/bin. Wasn’t hard to find the right options for HDA VERB. In my case
    Code:
    sudo hda-verb /dev/snd/hwC0D0 0x0d SET_CONNECT_SEL 0”
