I recently install Fedora 22 (x86_64) on my new laptop Asus ROG G551JW-DM282T PC Portable Gamer 15,6".

Sometimes the laptop just freeze and I cannot anymore use the mouse or the keyboard.

Can you help me, in which logs I can find any clues?

Before it happens again, activate and test the Magic SysRq Key. It doesn't tell you how to make the change permanent, but you can find it in the third post in this thread. Just remember to test it, because different systems need different key-combos to make it work.

Did you follow the links? You use the key combos to try to get control of your laptop and, if nothing else, get an orderly reboot. If that doesn't work, we know that it's the kernel that's frozen.

@sideburns Ok I tried to reboot with the Magic SysRq Key when my laptop crash and nothing happened. I had to power reboot. I tried when the laptop is fine and the reboot work. What is the next step to debug and find the problem?

Now, at least, we know that it's a kernel issue, and that X and everything else are OK. We also know that we can ignore any suggestions that disabling SELinux will help.
