Since then, it randomly freeze up while I work. It generally takes 10-20 mins to do that. Out of frustration, I started to change the kernel. It seems that every >4.0 kernel is freezing up my system. Now i am stable at 3.19.8 from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/ Please note: When using old kernel ( 3.19.8 ) i have no crash. But when i use the latest one, it freeze up and i can not use anything ( no kernel panic, no terminal, nothing, keyboard mouse doesn't work ). The freeze happens very randomly. It can take 5 mins or hours after working. And it takes me to switch off the laptop and start it again.
