Speaking to Lenovo won't automatically fix the issue, because it is way harder to get people to install bios updates than to accept kernel updates.
Fan control disengaged mode works: fan runs 4700 RPM, which keeps temperature down at 84 C after several minutes at full load. Unfortunately in disengaged mode the fan always runs 4700 RPM, no matter what temperature or load. So, make the system switch between fan control modes according to temperature and its growth rate to narrowly avoid hitting 100 C (it needs to be done on many affected Lenovos). -- 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/1491797 Title: Shuts down when supposed to suspend as a reaction to self-caused overheat, session lost Status in linux package in Ubuntu: Incomplete Bug description: Error: Kernel foolishly shuts down the computer when it overheats. /var/log/kern.log W500 kernel: [1448.648529] thermal thermal_zone1: critical temperature reached (100 C), shutting down Consequence: Shutting down destroys session in Ubuntu, Gnome, and all applications that can't remember their latest conscious state (most applications). Attempted repair, failed: Laptop has suspending ability, but I can't find the setting for the kernel to make the computer suspend instead of shutting down. Repair suggestions: 1. Persistence of session, so that everything would reappear after the restart. (this would also make updating less disruptive) 2. Do not heat the machine like crazy; speed up fans or slow down processes. (problematic Lenovo Thinkpad W500 fan on low speed right up to the fiery end) 3. Put the computer to suspend when it's too hot.
