Nick Moffitt, thank you for reporting this and helping make Ubuntu better. As per http://support.lenovo.com/us/en/products/laptops-and- netbooks/thinkpad-x-series-laptops/thinkpad-x240 an update to your computer's buggy and outdated BIOS is available (2.33). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-2.33 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1498387 Title: system hangs and CPU heats up in -29 but not -28 Status in linux package in Ubuntu: Incomplete Bug description: I filed this bug against linux-image-3.19.0-29-generic and hope that it has attached everything relevant. With linux-image-3.19.0-29-generic I can only run my thinkpad X240 for a few hours before I invariably trip over this bug and cause it to hang, heating up and driving the fan to full speed. I never have this trouble when I select linux-image-3.19.0-28-generic. Occasionally I'll reboot for updates (such as the recent network manager one) and forget to go down a build number, and I hit this again shortly after reboot. The screen remains in whatever state it was in, but I am unable to move the mouse or affect X with the keyboard (including trying to switch to a virtual console with Ctrl-Alt-F1). Nothing suspicious shows up in kern.log after the reboot, but I tend to have to do a hard power-off to get back to a useful machine so the journal may not be fully checkpointed in time.
