Now, I have  updated the BIOS version to latest one:

    sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
    83ET76WW (1.46 )
    07/05/2013

I have run the above command showing the BIOS verison. Problem still
persist.

In addiditon to this I have updated kernel version to 3.16.x but no luck
here as well.
