Hi guys, here's my final report: I managed to reproduce the problem even after installing ASUS Live update, even with smaller CPU usage. Key thing was to put more files to SSD (the problem came back, when SSD usage reached about 50 GB). So it seems both the CPU and SSD usage affect the stability. This was 3 weeks ago. I didn't post this earlier because I wanted to try to unplug the battery first, as Oleksij suggested. The most difficult part of this testing was to find a torx T5 screwdriver - seriously, the smallest I was able to find in Turku was T7! Fortunately my brother had one so when I visited him two weeks ago I was finally able to open my laptop and try this one last thing.
All crashing stopped completely after I opened my laptop and ***unplugged the battery***. I have so far tested this with Windows 7, Ubuntu 13.04 and 13.10, forced CPU usage to stay at 100% and filled my SSD up to 80% with 3 partitions (FAT32, NTFS and Ext4). Not a single crash in 2 weeks! I believe mine was actually a memory controller related problem that was originally caused by a bug in Ubuntu 11.10: https://help.ubuntu.com/community/AsusZenbook#Suspend Feels pretty stupid that I didn't try this 1½ years ago... maybe I was just too afraid of losing warranty (and I didn't find a suitable screwdriver) or something. But now everything works fine. I hope this helps. -- 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/989191 Title: Asus Zenbook UX31E powers off on plugin in/out AC adapter Status in The Linux Kernel: Unknown Status in “linux” package in Ubuntu: Triaged Bug description: When I have logged in to Unity and plug in or out AC adapter to Asus Zenbook UX31E, computer powers off.
