* use the fan up to its maximum speed (not up to what a designer years ago assumed would probably be enough)
  - see comment #13 for some guidelines.  As mentioned before, fan control by default is under firmware control.  So, one will have to enabled the thinkpad fan control manually to adjust fan settings outside of firmware control.  Have you tried these yet?

* in a heat emergency, suspend in 1 second instead of shutting down wasting 8 seconds and my session
   No.  The system has had a thermal overrun event that explicitly states to the machine "shut down" because the silicon is at risk from thermal meltdown.  This is the policy and will always be the policy.

Title:
  Shuts down when supposed to suspend as a reaction to self-caused
  overheat, session lost

Status in linux package in Ubuntu:
  In Progress

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.

  (The problem has remained the same from at least Ubuntu 11.10 through
  14.04)
