Well, Bios update did not improve the behaviour. But I finally upgrade kernels to 3.8 (after a complete backup) and no more freeze since this upgrade (http://askubuntu.com/questions/119080 /how-to-update-kernel-to-the-latest-mainline-version-without-any-distro- upgrade/142000#142000).
So for me case closed. ** Changed in: linux (Ubuntu) Status: Incomplete => Fix Committed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1273284 Title: [ASUS ZENBOOK Touch UX31A] Intermittent complete freeze Status in “linux” package in Ubuntu: Fix Committed Bug description: It's been some months, I'm experiencing complete freeze with my Ubuntu PC : mouse, keyboard are not responding, the fan accelerates to the max. It seems to me that it occurs randomly. Not exactly though because it never freezes when the screen is locked !
