I have dual boot system on my laptop (Windows 7 and Ubuntu 14.04 LTS). I do not face any freezing problem with Windows 7, it runs smoothly.

Whereas sometime in random interval I face freezing problem with Ubuntu. At this moment mouse key boards does not work. This problem persist even after upgrading BIOS.

I have tried existing solution with no luck. Please let me know what all other information is required to understand this problem.


First check your laptop specification. Basically there is much trouble with some hardware for you kernel. and also the performance of your integrated graphic.

In case someone else finds this, a kernel upgrade fixed a similar problem. I had Ubuntu 14.04.2 kernel version 3.16.0-30, and doing a "apt -y upgrade" ended me up at kernel 3.16.0-49, and that solved the problem.

  • As of now my kernel version is 3.13.0-71-generic. I will try to upgrade to kernel 3.16.x and let you know if I face similar issue. – snoop Dec 15 '15 at 8:05
  • Now, I have upgraded kernel version to 3.16.0-55-generic, still same issue. No improvements. – snoop Dec 15 '15 at 14:24
